Why Designing and Building a Custom House is Better Than Buying

Are you in the thrilling process of finding a new home? The decision to buy a house is a huge commitment, but have you considered the benefits of designing and building a custom house? While purchasing an existing home may seem like a convenient option, there's something truly exceptional about customizing every aspect of your dream home. In this blog post, we'll explore why designing and building a custom house is an incredibly rewarding choice, and more accessible than you might think.

Unleash Your Creativity

One of the most compelling reasons to choose a custom house is the opportunity to unleash your creativity. When you buy an existing property, you may have to make compromises and settle for features that don't align with your personal style, taste, or needs. On the other hand, with a custom house, you have the freedom to collaborate with a design team to craft a home from the ground up according to your preferences.

From the layout, architecture, and interior design elements to the selection of materials and finishes, every detail is under your control. You can create spaces that reflect your personality and accommodate your specific needs, whether it's a spacious open-concept living area, a home office with plenty of natural light, or a luxurious master suite. The possibilities are boundless.

Maximize Functionality

Another significant advantage of designing and building a custom house is the ability to maximize functionality. Existing homes might have limitations in terms of layout, storage, or access to natural light. By starting from scratch, you can optimize the entire design to suit your lifestyle perfectly and ensure the home will function according to how you live.

Consider your daily routines and the flow of your household. Are you an avid entertainer? Then you can design a welcoming and expansive dining area that seamlessly connects the kitchen and living spaces. Do you love spending time outdoors? Plan for a beautiful backyard with a deck or patio, providing an oasis for relaxation and alfresco gatherings.

Creating a custom house allows for clever storage solutions, smart home technology integration, eco-friendly features, and energy-efficient design choices. By incorporating these elements, you can ensure that your home not only reflects your preferences but also enhances your daily life.

Financial Investment

While designing and building a custom house may seem cost-intensive initially, it can actually be comparible as an investment to buying a house on the market, and should be a sound financial investment in the long run. When you buy an existing house, there may be hidden maintenance issues or outdated systems that could lead to unexpected expenses down the road. By starting fresh with a custom build, you have control over the quality of materials, appliances, and overall construction.

Additionally, a custom house offers better value retention. As your home is specifically tailored to your needs and preferences, it stands out from generic houses on the market. It will likely have a higher resale value due to its unique features, premium craftsmanship, and customized finishes.

Building for the Future

Designing and building a custom house allows you to future-proof your home. You can integrate sustainable and energy-efficient features, such as solar panels, high-quality insulation, and water-conserving fixtures. By prioritizing environmentally friendly choices during construction, you contribute to a greener future and potentially reduce your utility bills.

Custom houses also give you the opportunity to plan for the future. If you have a growing family or envision aging in place, you can incorporate adaptable features like wider doorways, no-step entrances, or a main-level bedroom suite. Building a home that caters to your long-term needs ensures comfort and convenience for years to come.

Conclusion

While buying a house offers immediate occupancy, designing and building a custom house provides an unparalleled opportunity to create your perfect sanctuary. From igniting your creativity and maximizing functionality to making a sound financial investment and building for the future, the benefits of a custom build are immeasurable.

If you're ready to embark on an exciting journey of self-expression and create a home that truly reflects who you are, the decision is clear. Consider the advantages of designing and building a custom house – a tailor-made abode that you can proudly call your own.

ADU Design Considerations for Short-term vs Long-term Rentals

In recent years, the popularity of accessory dwelling units (ADUs) has surged due to their potential as income-generating properties. Homeowners are capitalizing on the opportunities provided by short-term rentals, such as Airbnb or VRBO, or long-term rentals to supplement their earnings. However, when it comes to designing an ADU for these rental purposes, there are several important considerations to keep in mind. In this blog post, we will explore the key design considerations for both short-term and long-term rental ADUs.

Short-Term Rental ADUs

Flexibility and Guest Experience

When designing an ADU for short-term rentals, flexibility is key. Consider incorporating modular furniture that can be easily rearranged to accommodate varying guest preferences. Additionally, emphasize the overall guest experience by selecting high-quality and durable materials, modern amenities, and stylish furnishings that align with the target demographic. Strive to create a space that feels inviting, unique, and comfortable to ensure positive reviews and repeat bookings.

Knowing that the short-term rental market is becoming increasingly competitive, consider design elements that enhance the guest experience while becoming instagrammable moments. Let your guests help you market the rental through their social media and referring your rental to other potential guests.

Privacy and Separation

Ideally, an ADU designed for short-term rentals should provide a sense of privacy and separation from the main residence. Consider features such as a separate entrance, dedicated outdoor spaces, and soundproofing measures to minimize any disturbances between guests and hosts. A well-designed layout with distinct sleeping areas and private bathrooms can enhance the overall appeal of the space. Specifically, a detached ADU is an ideal unit because it is physically separated from the main house.

Functional Kitchen and Amenities

A fully-equipped kitchen with modern appliances is a significant factor for guests who prefer short-term rentals as they often are choosing to stay in an Airbnb rather than a traditional hotel. Ensure the ADU's kitchen is well-designed, with ample counter space, and essential cooking utensils, and easy to use appliances. Other amenities, such as laundry facilities, reliable internet, and entertainment options, should also be considered to enhance the overall guest experience.

ADU Storage Solutions

Short-term rental ADUs often attract guests who may have a fair amount of luggage. Incorporate clever storage solutions, such as built-in closets, shelving, or under-bed storage, to maximize space and allow guests to keep their belongings organized during their stay.

Long-Term Rental ADUs

Functional and Practical Layout

While short-term rentals prioritize aesthetic appeal, long-term rental ADUs should focus on practicality and functionality. Ensure that the design places emphasis on optimizing the available space for everyday living. Consider incorporating features like ample storage space, efficient floor plans, high performance systems, and and elegant and durable materials to cater to long-term tenants' needs.

Private Outdoor Spaces

Long-term tenants often appreciate outdoor spaces where they can relax and unwind. Design the ADU to include private patios, balconies, or even small gardens, providing a sense of tranquility and allowing tenants to enjoy some fresh air, and make the smaller size of an ADU feel larger.

Sustainable and Cost-Effective Features

Long-term rental ADUs can benefit from energy-efficient designs and cost-saving features. Consider integrating energy-saving appliances, LED lighting, efficient insulation, and solar power options. These features not only reduce utility costs for tenants but also align with environmentally friendly practices. They can also help your ADU rental unit stand out in the competitive rental market.

Privacy and Noise Reduction

Long-term tenants typically value privacy and minimal noise disruption. Incorporate measures such as soundproofing materials, separated entrances, and well-insulated walls to create a peaceful living environment. Adequate separation and privacy between the main residence and ADU are also essential to ensure a harmonious coexistence.

ADU Storage Considerations

Considering ADUs are smaller dwellings, careful consideration should be paid to the design of storage space. For long term tenants, you may want to consider spaces for larger items like bikes, camping gear, and even car parking. Ample closet space for clothes and personal belongings is a great start, but often people who live in a rental long-term have other items and dedicated storage space can be a huge selling point for your ADU.

Conclusion

Designing an ADU for short-term rentals versus long-term rentals requires distinct considerations to appeal to the target renters. Short-term rentals should prioritize flexibility, guest experience, and privacy, along with functional amenities. On the other hand, long-term rentals should focus on practical layouts, efficient use of space, and sustainable features, while also prioritizing privacy and peace for tenants. By carefully considering these factors, homeowners can ensure their ADUs cater to the specific needs and preferences of their chosen rental market, ultimately maximizing the property's income potential.

ADU Design Guidelines: Sustainable Features

Adding an Additional Dwelling Unit (ADU) to your property can be a great way to increase rental income or extend the life of your home. But before you start construction, it's important to make sure that your ADU is designed in a way that is both sustainable and eco-friendly. In this blog post, we will discuss some of the most important features to consider when designing an ADU.

Orientation

The orientation of an ADU plays a vital role in maximizing sustainability. By carefully considering the placement of windows, doors, and the overall layout, homeowners can optimize the use of natural light and ventilation. Orienting the ADU to capture an abundance of sunlight can reduce the reliance on artificial lighting during the day, ultimately saving on energy consumption. Additionally, strategic positioning can promote passive cooling and heating, reducing the need for excessive air conditioning or heating systems. For instance, placing windows on opposite sides of the ADU allows for cross-ventilation, ensuring fresh air circulates throughout the space. By prioritizing sustainable orientation, ADUs can minimize their environmental impact while providing comfortable and energy-efficient living spaces.

Materials

In designing an ADU, incorporating sustainable materials is a paramount consideration for conscientious homeowners and designers. Utilizing sustainable materials not only promotes environmental preservation but also enhances the overall energy efficiency and durability of the ADU. From the foundation to the roof, sustainable materials can be implemented throughout the entire construction process. Choices such as FSC certified framing, reclaimed wood, bamboo flooring, and locally sourced products not only lend a unique aesthetic charm to the ADU but also significantly reduce the project's carbon footprint. Additionally, extra insulation coupled with active systems like solar panels and efficient heat pumps for heading and cooling can optimize energy efficiency, reducing the dependency on traditional energy sources - potentially even making your ADU net-zero energy. By employing sustainable materials, every aspect of an ADU's design can contribute to a greener and more sustainable future.

Active Systems

Active systems play a crucial role in contributing to the sustainable design of an Accessory Dwelling Unit (ADU). Incorporating renewable energy sources such as solar panels can provide clean electricity to power the electrical components of the ADU. Other systems to consider include installing a rainwater harvesting system which can collect and store rainwater for various purposes, reducing the dependency on municipal water sources. Furthermore, incorporating a geothermal heating and cooling system can utilize the stable temperature of the earth to efficiently regulate indoor climate, reducing the need for fossil fuel-based heating and cooling. These active systems not only decrease the environmental impact of the ADU but also contribute to long-term energy savings, making them an essential component of a sustainably designed ADU.

Passive design strategies for ADUs

Passive strategies are crucial for the sustainable design of an Accessory Dwelling Unit (ADU). By incorporating these strategies, homeowners can achieve energy efficiency and reduce environmental impact while ensuring a comfortable living space. For example, designing the ADU to maximize natural daylight, utilizing large windows and skylights, may reduce reliance on artificial lighting during the day, thus saving energy. Another strategy is proper insulation and air sealing, which prevents heat loss in the winter and heat gain in the summer. This reduces the need for excessive heating or cooling, resulting in significant energy savings. Additionally, passive solar design can be implemented by orienting the ADU to capture natural sunlight and heat, coupled with interior thermal mass from things like concrete floors you can reduce the need for artificial heating and lower overall energy consumption. By integrating such passive strategies, ADUs can contribute to a sustainable and energy-efficient living environment for homeowners. Plus, passive strategies often don’t cost any more to incorporate into your ADU project.

Simplicity and Less is More

Embracing simplicity and adopting a "less is more" approach can prove to be a prudent strategy for a sustainable ADU project. By prioritizing simplicity in design, construction, and functionality, we can reduce the environmental impact associated with materials, energy consumption, and waste generation. A minimalistic approach not only promotes efficient resource allocation but also encourages thoughtful use of space, enabling the creation of compact, smartly designed living areas that optimize functionality within a smaller footprint. By consciously scaling down, we reduce the demand for resources and energy, curbing both carbon emissions and operational costs. Moreover, a simpler design aesthetic can withstand the test of time, reducing the need for frequent renovation and minimizing the consumption of additional materials over the lifespan of the ADU. In essence, simplicity and a "less is more" mentality offer a sustainable pathway for an ADU project that focuses on responsible and efficient resource utilization in an environmentally conscious manner.

In conclusion, ADUs have emerged as a practical and sustainable solution to address the changing needs of homeowners and communities across the country. With their flexibility, affordability, and minimal impact on the environment, ADUs have transformed the way we think about housing. By providing an additional living space, ADUs not only offer a way to combat the housing crisis but also promote multigenerational living, create opportunities for rental income, and foster community cohesion. As cities adapt their policies and regulations to facilitate the construction of ADUs, it is clear that these innovative structures will continue to play a crucial role in shaping the future of housing, offering both homeowners and renters a versatile and efficient living option. The next step is making every ADU as sustainable as possible, to ensure that these housing types are great for our communities as well as the environment we call home.

Unlocking the Potential of Your Property: The Power of Backyard Cottage Plans

Are you a homeowner looking to optimize the space on your property and create an additional living area that serves multiple purposes? Look no further than the charm and versatility of a backyard cottage, otherwise known as an accessory dwelling unit. In this article, we'll explore the many benefits of incorporating a backyard cottage into your property and discuss why purchasing a pre-designed ADU plan can be a game-changer. From accommodating loved ones to generating rental income, backyard cottages offer a range of possibilities. So, let's dive into the world of backyard cottage plans and discover the transformative potential they hold.

Maximizing Your Space with Backyard Cottage Plans

Backyard cottages, also known as accessory dwelling units (ADUs), have emerged as a popular solution for homeowners seeking to maximize the the potential of their property. By utilizing the available space in your backyard, you can unlock the untapped potential of your property and enhance its value - all for less investment than purchasing another property.

The benefits of having a separate living area within your property are numerous. Firstly, backyard cottages provide a convenient and comfortable space for accommodating guests. Instead of squeezing visitors into your main residence, a separate living area offers privacy and independence for both you and your guests, especially for extended stays. Additionally, a backyard cottage can serve as an ideal home office, providing a quiet and dedicated workspace away from the distractions of your primary dwelling. This setup promotes productivity and work-life balance and is an increasingly popular home amenity with more and more remote or hybrid work arrangements. Furthermore, backyard cottages open up opportunities for generating rental income. By renting out the cottage, homeowners can generate passive income or offset mortgage costs, making it a smart financial investment.

When considering the construction of a backyard cottage, opting for a pre-designed plan offers significant advantages. A pre-designed backyard cottage plan streamlines the construction process and saves valuable time. These plans are meticulously crafted by experienced ADU designers who understand the intricacies of ADU construction and maximizing the livability of smaller sized dwellings. By choosing a pre-designed plan, you gain access to a comprehensive blueprint that is tailored to maximize functionality and beautiful, modern aesthetics. This eliminates the need to start from scratch and go through the time-consuming design and approval process. With a pre-designed plan, you can confidently move forward with your ADU construction project, knowing that you are working with a proven design that limits your risk.

Convenience and Efficiency of Pre-Designed ADU Plans

Most homeowners like you want to see what you are going to get before paying for an ADU design. Pre-designed ADU plans are a great way to start the path to building an ADU in your backyard while seeing the design before you get started. It takes the guesswork out of the design process.

Purchasing an ADU home plan also is more convenient than going with a custom design as most of the work is already done. It saves months of time and eliminates the stress of having to make hundreds of design decisions. Starting with a ready-to-use ADU blueprint makes adding a backyard cottage a relatively simple process which ultimately saves both time and money.

One the biggest benefits of selecting one of our modern ADU designs is that they are all crafted by experienced designers who have been designing beautiful ADUs for years. The plans are proven to be livable, efficient uses of space, and offer a range of styles that can compliment almost any main home. Our plans are carefully crafted to be incredibly functional and are optimized to provide great places to live within the size limitations placed on ADU projects.

By not starting from scratch you get reduced cost, a faster timeline to completion, and a proven ADU design that is beautiful, functional, and affordable.

Customization within Pre-Designed Backyard Cottage Plans

Although we believe that the best option is to pick the plan that best meets your needs and jump right into the engineering and permitting process, we understand that sometimes you may want to make some tweaks or revisions to the ADU plans we offer. Customization is definitely a possibility and can still end up being more affordable than going with a fully custom ADU design process.

We work closely with many of our clients to make adjustments to our plans to meet your needs or taste. This can include small tweaks to the interior layout, kitchen cabinets, or windows, to larger changes to the overall form and structure. Of course, there will be some extra fees for this work and the more changes you make the higher those need to be. But overall this is still a very economical way to get a beautiful ADU that is semi-custom and adjusted to your unique property or project goals.

Along with some design changes that need to be documented in the drawing set in order to get engineering and building permits approved, there are many smaller changes that you can control later in the process. There is a lot of flexibility with the selection of interior finishes that you can make further down the road. Things like tile selection, cabinets, countertops, and even flooring or light fixtures can be ways that you can put your fingerprint on the project and customize the design to meet your taste.

If there is one of our designs you are leaning towards but you have ideas for changes, don’t hesitate to reach out and we can discuss doing a semi-custom projects specifically for you. We will simply listen to your ideas, offer some thoughts, and then put together a proposal based on the agreed upon scope of work. It is simple, straight forward and with our fixed prices you never pay more than what we quote for the changes.

Time and Cost Efficiency of Pre-Designed ADU Plans

None of us have enough time, especially when you are balancing jobs, family commitments, and want some time leftover for fun, hobbies, or relaxing. Saving time is one of the biggest values of starting with a pre-designed ADU or guest house floor plan. Starting with a plan set eliminates the lengthy design process typically associated with custom ADU designs. In general we typically find that a custom design takes about 6 months from start to being ready to submit for permit approval. Starting with a pre-designed plan for your backyard cottage or rental unit can bring that timeline down to just a month or so.

And since you are starting with a set of drawings ready to go, you can bring them straight to a contractor to get cost estimates on day one. Rather than working for months crafting a design only to find it is above your budget, starting with a finished plan can give you a better sense of the total project cost from day one. In fact, some of our clients have come to us with a builder already on board so they get rough cost feedback prior to making a purchase. This makes budgeting and financial planning more manageable for your ADU project.

Let's also talk about design fees here for a minute. We have designed over 50 custom ADU projects and have talked with architects and designers who have done hundreds of these projects. In general you can expect to pay between 10-15% of the total project cost on design fees when going the custom route. Prices can vary but if you see fees that are much lower than that I’d have serious reservations about the quality of the design you will receive. On the other hand our designs start at around one thousand dollars. This is a huge cost savings when compared to the custom route. Even if you want to make some revisions to our designs, the final price will typically be less than half of the cost of a custom ADU design.

We can provide our plans at a fraction of the cost because of economies of scale. We develop our designs to work on a wide range of properties, fit a range of styles, and come in a variety of sizes and configurations so we don’t have to start from scratch for each project. These savings are passed on to you.

Peace of Mind and ADU Expertise

Starting a project of this magnitude can be intimidating and stressful. ADUs, although relatively small in size, still are a significant investment. Our goal is to give you peace of mind and start you off on the right foot. We have over a decade of experience designing ADU projects and embed this vast design knowledge into each plan set. Our pre-designed backyard cottage plans are created by professionals with experience in ADU design and construction, giving you a higher quality project for a much lower cost.

The plan you select has been carefully crafted to reduce the risk of design flaws or unforseen issues. Our experience leads to plans that are relatively simple and affordable. They maximize the use of space - which is imperative in these small homes - and recommend systems that are efficient and increase the comfort of living in the ADU.

And importantly we offer support, guidance, and access to additional resources and knowledge to help your project be a success. Along with the drawings themselves we offer consultations, custumizations, and can be on call if you need additional design support.

Conclusion

Backyard cottage plans offer homeowners like you an incredible opportunity to maximize your property's potential, whether it's creating additional living space, accommodating loved ones, or generating rental income.

A Homeowner's Guide to Financing ADU Projects: Unlocking the Potential of Your Property

Imagine this: You've been living in your cozy home for years, cherishing countless memories within its walls. But as life evolves, you find yourself needing additional space for various reasons—an aging parent who requires close care, a growing family, need for a home office, or even an opportunity to generate passive income. That's when the idea of an Accessory Dwelling Unit (ADU) comes into play. This comprehensive guide will walk you through the financing options available to homeowners like yourself, empowering you to turn your ADU dream into a reality.

Meet Sarah, a homeowner with a growing family and a desire to create a separate living space for her elderly parents. She wanted her parents to be close by, yet maintain their privacy and independence. Sarah had heard about ADUs and was fascinated by the concept, but she had concerns about financing such a project. However, after researching different options and exploring financing avenues, she discovered a range of possibilities that made her ADU dream achievable within her budget. Inspired by Sarah's success, let's delve into the world of financing ADU projects and explore the various avenues available to homeowners.

Understanding the Cost of ADU Projects Before exploring financing options

It's essential to have a clear understanding of the potential costs involved in ADU construction. Factors such as size, design complexity, location, and desired amenities can significantly impact the overall budget. By carefully evaluating these elements, you can develop a realistic financial plan and explore suitable financing options.

Based on recent construction data, detached, new construction ADUs can fall anywhere from $200,000 to almost $1,000,000 to build. This is a crazy wide range, but it reflects the variety of ADUs, the various costs in different markets, and the complications that each unique site or design can have on construction costs. If you take out the outliers, building a project budget of between $240,00 to $380,000 would allow you to build a high-quality accessory dwelling unit project.

Traditional Financing Solutions for ADUs

These are some of the most common and easiest ways to get financing for the construction of your ADU project.

1. Home Equity Loans and HELOCs: Utilizing the equity in your home to secure a loan can be an effective way to finance your ADU project. Home equity loans provide a lump sum, while a Home Equity Line of Credit (HELOC) allows you to access funds as needed.

2. Cash-Out Refinancing: If you have substantial equity in your home, consider refinancing your mortgage to access cash for your ADU project. This option allows you to replace your existing mortgage with a new loan while withdrawing a portion of your home's equity as cash. Typically this would mean taking out a new 30-year mortgage which can spread your ADU payments out over a long period of time. This is great for rental units as it can mean having positive cashflow on a monthly basis.

Government ADU Financing Options

1. FHA 203(k) Rehabilitation Loan: This program is designed for homeowners seeking to finance both the purchase or refinancing of a home and the cost of ADU construction. It provides a single loan, combining the costs into one mortgage payment.

2. Fannie Mae HomeStyle Renovation Loan: Similar to the FHA 203(k) program, this loan option allows homeowners to finance the purchase or refinance of a home along with the cost of renovations, including ADU construction.

Alternative Financing Strategies for ADU Projects

1. Construction Loans: These loans provide short-term financing to cover the costs of construction. Once the ADU is complete, homeowners can refinance the construction loan into a traditional mortgage.

2. Personal Loans: For smaller ADU projects, personal loans can offer a flexible financing solution. Although interest rates may be higher, they often have less stringent requirements and faster approval processes.

3. Hard Money Loans: A hard money loan is a specific type of asset-based loan: a financing instrument through which a borrower receives funds secured by real property. Hard money loans are typically issued by private investors or companies. The downside of using hard money loans is they typically have a high interest rate and shorter repayment term.

ADU-Specific Financing Programs

Some regions and organizations offer specialized financing programs tailored to ADU projects. Research local programs, grants, or incentives that may help offset the costs of construction or provide favorable loan terms. These programs rarely will cover the full cost of building an ADU but can be combined with some of the other financing options described above to help you cover the full project costs.

Embarking on an ADU project can be a transformative journey that enhances your living situation and opens doors to new possibilities. By understanding the costs involved and exploring various financing options, homeowners like you can confidently pursue their ADU dreams. Whether it's tapping into home equity, leveraging government programs, or exploring alternative financing strategies, the path to financing your ADU project is within reach.

ADU Design Guidelines: Mechanical, Electrical, and Plumbing systems

Modern ADU Plans: A Comprehensive Guide to Mechanical, Electrical, and Plumbing Systems for Your ADU Project

If you're considering building an Accessory Dwelling Unit (ADU) on your property, it's essential to familiarize yourself with the intricate systems that make these structures functional and efficient. In this comprehensive guide, we will delve into the world of Mechanical, Electrical, and Plumbing (MEP) systems specifically tailored for ADU projects. As an expert architect, I will provide you with the knowledge necessary to make informed decisions and ensure a successful ADU construction process.

Mechanical Systems: Efficient Comfort at Your Fingertips

Mechanical systems play a vital role in providing comfortable and healthy living conditions within your ADU. A well-designed heating, ventilation, and air conditioning (HVAC) system will help maintain suitable temperature levels, adequate indoor air quality, and efficient energy usage.

Consider installing a zoned HVAC system to optimize comfort and reduced energy consumption. This way, you can independently control the temperature in various areas of your ADU, ensuring personalized comfort for you and your tenants. Additionally, investing in Energy Star-rated appliances will not only save you money on utility bills but also contribute to a greener environment.

For ADUs we typically recommend ductless mini-split systems as they are efficient, provide both heating and air conditioning, and can have multiple wall mounted units to allow for individual controls per room. Another option we have integrated into ADU projects is radiant floor heating.

Electrical Systems: Powering Your Modern ADU

The electrical system is the backbone of your ADU, providing the necessary power for all your appliances and devices. From lighting fixtures to kitchen appliances and entertainment systems, it's crucial to plan the electrical layout meticulously.

To maximize efficiency and safety, consult with a licensed electrician during the design phase. A well-designed electrical system will ensure ample power supply and prevent overloaded circuits. Also, consider incorporating energy-efficient LED lighting and smart home technology to enhance energy savings and convenience.

We always design fully electric ADUs with the goal that any of our ADUs can be converted to net zero energy projects by installing solar panels. And if solar isn’t possible due to your property, you can still purchase sustainably generated power from your utility company.

Plumbing Systems: Seamless Water Flow

Plumbing systems are the lifeline of any ADU. Adequate water supply, efficient wastewater disposal, and reliable water heating are essential components of a proper plumbing system. Consult with a plumbing professional to ensure the plumbing layout meets local building codes and regulations. Installing low-flow fixtures, such as toilets and faucets, can help conserve water and reduce monthly utility expenses. Consider integrating a tankless water heater to provide an instant and endless supply of hot water, enabling your tenants to enjoy the comforts of modern living.

The Benefits of Modern Design for Your ADU: What You Need to Know

As the popularity of accessory dwelling units (ADUs) and laneway houses continues to rise, so does the demand for modern designs that fit seamlessly into their surroundings.

When it comes to ADU design, modern style has become increasingly popular in recent years. But what does "modern design" actually mean for ADUs, and why should you consider it for your next project? In this blog post, we'll take a closer look at modern design principles that we incorporate into ADUs.

Minimalism and Simplicity

One of the key features of modern design is minimalism and simplicity. This means that modern ADUs often have clean lines, simple forms, and a lack of ornamentation. The focus is on functionality and practicality, which can be especially useful when designing a small space like an ADU. We believe in the philosophy of less, but better. Meaning we keep the form of our ADU designs simple and efficient but invest in high quality systems and materials leading to a better end result. Consider quality over quantity.

Natural Materials

Modern design also emphasizes the use of natural materials, such as wood, stone, and metal. These materials are often used in their raw or untreated state, giving the ADU a more organic and authentic feel. The use of natural materials also helps the ADU blend in with its surroundings and create a more harmonious relationship with nature. We love natural cedar siding, exposed wood in the interiors, and concrete floors. Being true to the materials lets us celebrate how our buildings are built while relying on the natural beauty of the material to be the defining design features in our ADUs.

Energy Efficiency

Modern design principles often prioritize energy efficiency and sustainability. This means incorporating features such as high-quality insulation, efficient heating and cooling systems, LED lighting fixtures, and energy-efficient appliances. By designing an ADU with energy efficiency in mind, you can reduce your carbon footprint and save money on utilities in the long run. This coincides with the simple forms we discussed above, as we aim to design tight building envelopes that are energy efficient and optimized for the local environment.

Open Floor Plans

Another hallmark of modern design is open floor plans, which prioritize flow and connectivity between different spaces. In an ADU, an open floor plan can help create a sense of spaciousness, even in a smaller space. It can also make the ADU feel more versatile and adaptable to different uses. The best example of this is by designing a “great room” that combines the kitchen, dining, and living spaces into one open room. This helps make smaller sized ADUs feel spacious and they are more functional than having separate rooms for each function.

Large Windows and Natural Light

Modern design principles emphasizes the use of large windows and natural light to create bright and airy spaces. This can be especially important in an ADU, where space may be limited. By incorporating large windows and plenty of natural light, you can create an inviting and comfortable space that feels much larger than it actually is. Additional benefits include using natural light which can reduce energy use, and natural ventilation which can create a more comfortable and healthy indoor environment. Plus we use large windows and sliding doors to make strong visual impact on our ADU designs, creating more beautiful design solutions.

Conclusion

Modern design can help create ADUs that are both functional and aesthetically pleasing. By prioritizing minimalism, natural materials, energy efficiency, open floor plans, and natural light, you can have an ADU that is perfect for your needs. Whether you're building an ADU as a rental property, a guest house, or a place for aging relatives to live, a modern design can help you achieve your goals while creating a beautiful and comfortable space that will stand the test of time.

Why settle for prefab? Here's why a custom ADU design is the way to go.

When it comes to building an accessory dwelling unit (ADU), there are two main options: choosing a prefabricated unit, or investing in a custom ADU design. While prefab ADUs seemingly offer a quick and easy solution for those seeking an additional dwelling space, they are not the best fit for everyone. Here are a few reasons why a custom ADU design might be the way to go to achieve your ADU dreams.

An ADU tailored to your needs and preferences

A custom ADU design allows you to tailor your unit to your specific needs and preferences. With a prefabricated ADU, you are often limited to a set number of design options that may not fit your unique needs. A custom ADU design, on the other hand, allows you to work with a designer or architect to create a space that is exactly what you need and want. Having worked with hundreds of clients over the years, we love taking client’s ideas and crafting beautiful solutions. Even with our pre-designed ADU plans, we offer customization services to adapt the designs to client’s needs.

An ADU that fits your property

One of the biggest downsides to a prefab ADU is that it may not fit your property. Because these units are pre-designed, they may not work with the specific layout of your property, potentially leading to difficulties during installation. Features such as trees, existing structures, site topography, or adjacent power lines or other utilities could hamper the ability to install a prefabricated ADU. With a custom ADU design, you can ensure that the unit fits your property and takes advantage of site features, orientation, views, and other strategies to seamlessly integrate the new unit to your property.

Materials, systems, and finishes selection

While prefab ADUs are often marketed as a more affordable option, the materials used in their construction are typically pre-selected by the company fabricating the unit. There is limited opportunity for you to pick the materials, finishes, fixtures, and systems that will define the look and feel of your ADU. A custom ADU design allows you to choose the materials, leading to a design that aligns with your style. Plus you have the opportunity to focus on picking materials for durability, quality, and sustainability.

An environmentally friendly ADU

Custom ADU designs can be more environmentally friendly than prefab units. One of the biggest advantages of a custom design is it can be tailored to respond to the site, climate, and take advantage of active and passive strategies for sustainable design. Orienting the ADU’s roof towards the sun and adding a PV system could make your ADU a net-zero energy home. Designing the unit to get natural light and ventilation can reduce energy usage further and create a healthy indoor environment. Because you are able to choose the materials, systems, and features of your unit, you can select high-performance, environmentally friendly options such as energy-efficient appliances, solar panels, solar hot water systems, and sustainable building materials. This can lead to a lower environmental impact and reduced energy costs over time.

Custom design doesn’t have to cost more

Many prefab ADU companies will advertise that their units are more affordable than a custom solution. On the surface this could look like it is true. The price tag on many prefab accessory dwelling units are very attractive. However, it is important to consider the full costs of adding an ADU. Often prefab ADU prices don’t include things like site prep, getting utilities to the ADU, concrete work, pathways and landscaping, permitting fees, and other important aspects of adding an ADU. At the end of the day, the size of the unit, quality of materials selected, and the finishes, fixtures, and systems chosen for the ADU are the biggest determining factor of project cost. A custom design could come in at the same overall cost as a prefab unit and in some cases could even be cheaper. We have designed many nice ADUs that are comparable in cost to the prefab designs we see on the market.

In conclusion, while prefab ADUs can be a quick and easy solution for some, a custom ADU design is often the better option. With a tailored design for your taste and property, ability to select all the materials, and the ability to design a great accessory dwelling unit within your budget, a custom ADU is a smart investment in the long run.

We would love to help you achieve your ADU goals. whether through a fully custom design or by starting with one of our pre-designed ADU plans and adapting it to meet your needs. You can check out our plans for sale here, or contact us if you are thinking about doing a custom ADU.

Building a Laneway House in Vancouver? Here's What You Need to Know

Vancouver: a city of towering glass skyscrapers, sweeping mountain and ocean vistas, and laneway houses! These tiny homes are a quintessential part of the city's character, but what are the regulations for building one? Let's take a look.

First things first: what's a laneway house, you ask? Think of it as a tiny home that's built in the space between the main house and the back alley. They're typically around 500-750 square feet, may include an attached garage, and they're perfect for adding some extra housing stock to the city without taking up more green space.

Now, the regulations. Here are the basics:

1. You have to own a house that's already on the property. Sorry, apartment-dwellers, you're out of luck on this one. But if you're a homeowner looking to add some extra rental income or a place for grandma to stay, they are a great option. You can include an ADU or Laneway House as part of a development of a new house.

2. You have to have a back alley. This one should be pretty self-explanatory, but just in case you were thinking of paving over your backyard to make a "faux" alley -- don't. Laneway houses have to face onto an actual city-owned laneway.

3. Your lot has to be at least 32 feet wide. Sorry, skinny lot owners, but you need a bit more space to make a laneway house work. The lot also has to be at least 3,000 square feet in size.

4. You have to follow size and design regulations. According to the City of Vancouver’s Laneway Housing How To Guide “Laneway housing regulations allow for a range of architectural approaches and building forms, from traditional to contemporary. Special design considerations apply to upper storeys, windows, landscaping, and lane frontages to enhance neighbourliness and liveability.” Laneway houses can't be bigger than the main house on the property, and they can't be taller than 17 feet with a sloped roof or 14 feet if the roof is flat. They also have to be set back at least 16 feet from the main house, and they have to fit into a certain aesthetic style that matches the neighbourhood. Think of it as a tiny design challenge!

5. A laneway house should be located and designed to preserve existing trees, including those on neighbouring properties and City property. The city requires an arborist report as part of the permitting process to ensure trees are protected.

6. Unfortunately, a parking space is required which doesn’t make sense in a dense and expensive city like Vancouver that has good public transit options and bike infrastructure. But even a progressive city like Vancouver can make bad regulations. So as you consider your ADU project, just remember that you will most likely have to slide a parking space next to your Laneway house.

7. You have to get a permit and pass an inspection. This one shouldn't come as a surprise, but it's worth mentioning. You'll need to get a permit from the city before you start building your laneway house, and you'll have to pass an inspection before it's deemed habitable.

All of these regulations might seem like a lot, but don't worry -- they're there to make sure that laneway houses are safe, functional, and fit in with the character of the city. It is recommended that you hire a designer to assist with the project - even the City of Vancouver’s Laneway Housing How To Guide recommends hiring someone. Plus, once you've navigated the rules and built your own little laneway oasis, you'll be the envy of all your neighbours.

So, there you have it: the regulations for building a laneway house in Vancouver. It's a bit of a process, but the end result is a charming, functional little home that can provide extra income, increase your property value, and housing options for the city.

If you have any additional questions about how to get started with a Laneway house or would like us to help guide you through the design process, please reach out through the button below.

Understanding California's Title 24 Requirements for Accessory Dwelling Units

Accessory Dwelling Units, or ADUs, are becoming an increasingly popular way to add living space and housing options to existing residential properties. In California, ADUs are subject to a number of regulations and requirements, including Title 24 of the California Code of Regulations. Title 24 sets standards for energy efficiency, lighting, and other aspects of building design and construction. In this blog post, we will explore California's Title 24 requirements for ADUs and explain what homeowners and builders need to know to ensure compliance.

Promoting Energy Efficiency

One of the main purposes of Title 24 is to promote energy efficiency and reduce the environmental impact of buildings. California has set ambitious goals for reducing greenhouse gas emissions and promoting sustainable building practices, and Title 24 is a key tool in achieving these goals. The regulations apply to all new construction and remodeling projects in the state, including new construction ADUs.

Insulation, Systems, and Construction Considerations

For ADUs, Title 24 requires compliance with specific energy efficiency standards. This includes requirements for insulation, air sealing, heating and cooling systems, and more. For example, ADUs must have insulation that meets minimum R-value requirements, and they must be designed to minimize air leakage. HVAC systems must also meet certain efficiency standards to reduce energy consumption and emissions. We typically recommend that ADUs have insulated wall cavities in addition to continuous rigid insulation around the entire outside of the home. We also recommend ductless mini-split systems as an efficient way to provide heating and cooling.

Lighting Considerations

In addition to energy efficiency requirements, Title 24 also sets standards for lighting in ADUs. These requirements are designed to promote energy efficiency and ensure that ADUs are well-lit and safe for occupants. This includes requirements for the type and placement of light fixtures, as well as the use of lighting controls such as timers and motion sensors. To meet lighting requirements and reduce energy consumption we recommend LED light fixtures throughout all ADU projects.

Accessible Design

Another important aspect of Title 24 for ADUs is the requirement for accessible design. California law requires that all new construction and remodels meet accessibility standards under the Americans with Disabilities Act (ADA). This includes ADUs, which must be designed to be accessible for individuals with disabilities. This may include features such as wider doorways, lower countertops, and accessible bathroom facilities.

Solar Energy Requirements

An important aspect of Title 24 is the requirement to add solar energy systems that will offset the energy use of new construction residential projects. This includes ADUs. It is important to consider this requirement when budgeting for your project as well as locating the ADU on your property. Making sure the roof pitch is best oriented towards the sun will help you get the maximum benefits of a PV system. Along with solar energy production, you could also consider solar hot water systems and a way to further reduce your energy consumption and make your ADU more sustainable.

How To Comply

Most jurisdictions in California require a Title 24 report that analyzes your ADU design and does that calculations to show it complies with the code requirements. There are many companies that can provide these reports in only a few days time and typically for a few hundred dollars. They will provide the documentation and/or drawings needed to submit to your building department as part of the permit review process.

Overall, California's Title 24 requirements for ADUs are designed to promote energy efficiency, safety, and accessibility. While complying with these requirements can add some additional costs to a project, it is important to ensure that ADUs are built to the highest standards of quality and sustainability. By following these requirements, homeowners and builders can create ADUs that are comfortable, safe, and environmentally friendly, and that will provide long-lasting benefits for years to come.

Typically Title 24 reports are performed once the design of the ADU is completed but prior to submitting to permit. You can use our pre-designed ADU drawing sets to send to a company that provides Title 24 Reports and typically you can get the report in a few days.

Seattle Is Permitting More ADUs Than Single Family Homes

According to a recent article in the Seattle Times, the growth in popularity of ADUs has seen the more ADUs permitted than single family houses. This is a welcome change in that it shows that changes to local regulations meant to encourage ADUs are working, but also that demand ADUs and multi-unit properties is outpacing the antiquated idea of single family houses in our cities.

We are definitely a fan of densifying our cities and ADUs are an important part of that. Density is beneficial for everyone as it leads to more amenities, new neighbors, more customers for local small businesses, and a larger tax base to fund public infrastructure like public transit, parks, and schools.

One of the things that drives what we do is providing more housing opportunities and more affordable homes. As this article points out, ADUs can help achieve these goals whether they are for rental or turned into a for-sale home by condoizing the property.

It is encouraging to see so many new homes being permitted, although this is still just a small drop in the bucket for the number of homes we need to be building to keep up with demand and growth projections. We would love to see ADU regulations be standardized state-wide or even nationally, rather than city by city. Having a patchwork of different rules and restrictions makes ADUs harder to design and build and often limits some types of ADUs, like modular or pre-designed ADUs.

We believe it would benefit everyone to make ADUs more accessible by taking down barriers to this housing type. It would make housing more affordable overall, it would make ADUs more attainable for more homeowners, it would allow for more multi-generational living or co-housing options, and will help meet our housing needs by working within the context of our many single family housing neighborhoods.

Another interesting aspect of this data is the balance between detached ADUs (DADU) - or backyard cottages - and attached ADUs - often called junior adus - which are often renovations to interior spaces like basements or attics. Detached ADUs are definitely leading the way but it was pretty close

It is also interesting to read that ADUs are becoming an amenity that developers are including in new homes. Rather than taking a property and building a single family house, developers see the interest in ADUs and are making projects that already have detached ADUs or attached adus included. And in places where it is allowed, sometimes both - meaning 3 units are being built instead of just one. This is really great to see.

Still, ADUs are a very small percentage of the overall housing production, with the most homes coming from new multi-family housing developments. Out of the approximately 11,000 homes built in the Seattle area, a little under 1,000 came from ADUs. Backyard Cottages, basement apartments, garage conversions, and other types of ADUs are still growing in popularity and will continue to be an important part of our future housing supply. Especially in neighborhoods that aren’t zoned for larger scale development, ADUs can easily become the easiest and most affordable way to add new homes.

Overall, this is great to see in the Seattle area and aligned with what we are seeing in many cities across the country. As more state legislatures adopt state-wide ADU regulations we are optimistic that ADUs will become an even larger piece of the housing pie.

10 Design Features of Accessible ADU Plans

Designing an accessible ADU is an important consideration for homeowners who want to create a living space that accommodates the needs of all individuals, regardless of mobility or disability. This is especially important when building an ADU for an aging family member, or when downsizing your home as you get older. By incorporating universal design principles and accessibility features into ADU plans, homeowners can create a space that is functional, comfortable, and safe for everyone. In this blog post, we will explore the key design features of accessible ADU plans. We will also highlight some of the benefits of designing an accessible ADU and provide tips for homeowners who are considering this type of project.

10 Design Features of Accessible ADU Plans:

1. Wide doorways and hallways: Accessible ADUs typically have wider doors and hallways to accommodate wheelchairs and other mobility devices. This also may lead to extra space around furniture to allow for easy movement around the accessory dwelling unit.

2. No-step entry: A no-step entry eliminates the need for stairs or steps, making it easier for wheelchair users to enter and exit the ADU. This could take the shape of a ramp or landscaping paths that lead up to the ADU level. We also typically look to do slab-on-grade construction for ADUs to keep the floor level as low as possible to allow for easier transitions.

3. Open floor plan: An open floor plan provides plenty of space for maneuvering a wheelchair or mobility device. This design feature also allows for flexibility in furniture arrangement.

4. Accessible kitchen: An accessible kitchen typically features countertops at a lower height, ample floor space for turning a wheelchair, and accessible appliances and storage. We used these strategies in the kitchen design for the Modern Japandi ADU - with custom height counters at 32” plus a space on the island without lower cabinets so a wheel chair could roll under the counter.

5. Accessible bathroom: An accessible bathroom often includes features such as a roll-in shower, grab bars, and a toilet with sufficient clearance on both sides. For the Modern Japandi ADU we did a barrier free shower, extending the floor and wall tiles into the shower area for seamless transition. We also used a special toilet paper roll hanger that doubles as a grab bar. We put extra blocking in the walls of the shower so additional grab bars could be added in the future. We also made sure to specify a shower head that had a hand shower attachment which is helpful when bathing with limited mobility.

6. Lever handles: Lever handles on doors, cabinets, and faucets are easier to operate than traditional knobs and handles, making them ideal for individuals with limited hand strength or mobility.

7. Non-slip flooring: Non-slip flooring can help prevent slips and falls, which can be especially dangerous for individuals with mobility impairments. We carefully select tiles and other flooring materials that won’t get slippery even when wet.

8. Adequate lighting: Adequate lighting is important for individuals with low vision or vision impairments. A well-lit ADU can also help prevent falls and accidents. WIth ample light fixtures and dimming switches we aim to give a wide range of lighting options that can be adjusted based on the time of day or lighting needs for specific activities.

9. Universal design: Universal design principles aim to create spaces that are accessible and usable by everyone, regardless of age or ability. Accessible ADUs often incorporate universal design features to make them more functional and appealing to a wider range of users.

10. Single Floor ADUs: this one may be obvious but many of our ADUs are designed as a single level to allow them to be more accessible for all. Stairs are a big barrier and a risk when getting older. Making sure there is at least one bedroom and one full bathroom on the main level of the ADU, or having the entire ADU on one level makes it possible to be converted into an accessible ADU that is ideal for aging-in-place.

By incorporating these design features into accessible ADU plans, homeowners can create a living space that is functional, comfortable, and safe for individuals with disabilities or mobility impairments. Accessible ADUs can also provide a valuable solution for families seeking a home that accommodates their unique needs.

We have worked with clients on a range of accessible ADU designs and have translated our lessons learned into many of our available ADU plans for sale. Check out our shop for the single level ADUs. We can also work with you to make adjustments to one of our designs or custom design an accessible ADU that will meet your needs.

This bathroom was designed specifically for accessibility. The room has extra width allowing for the turning radius of a wheel chair. The toilet paper holder is designed to double as a grab bar to assis with getting on and off the toilet. The shower is barrier free with the tile seamlessly flowing into the bathing space with a linear drain across the back. The shower is equipped with a hand shower making bathing easier from a seated position.

Prefab ADUs vs Pre Designed ADUs vs Custom Designed and Built ADU

You may be thinking about adding an ADU to your property and considering the best option to achieve your goals. There are three primary ways to deliver an ADU project: Prefabricated ADUs, Pre Designed ADUs, and Custom Designed ADUs. All have their strengths and weaknesses which we discuss below.

Prefab ADU

Before we discuss the strengths and weaknesses of this approach lets quickly touch on the definition of Prefab vs Modular and other common terms. Prefabricated typically refers to projects where all, or parts of the building are manufactured in a factory and shipped to the site to be assembled. This could be wall panels, roof trusses, and other specific building components, or could be the whole unit itself. Modular construction is typically referring to projects where the whole unit is made off site and shipped as a single object and the placed on a foundation. Sometimes multiple modules are combined together to complete the structure. For example, when you are driving on the highway and see those extra wide load trucks with homes on the back, that would be a modular home. If you see a truck that is flat packed with wall panels, that would be prefabricated. For this article we lump these two approaches together in this prefab ADU category.

The main advantage to prefab is a potentially faster schedule, and that build quality could be better within a factory where they don’t have to deal with weather and other site conditions and where machines and better tools could allow for more accurate construction. Many prefab companies will state that their builds are higher quality with smaller tolerances when compared to site build ADUs.

The other advantage is that often these can be built ahead of time and sold as a product, meaning the length of time for the construction can be dramatically cut down. If the unit is already built and just needs to be shipped to site, all that would be needed is site specific work like utilities, foundations, etc. at which point the finished unit could be craned into place and installed in a couple of days.

While the time argument is compelling, not many of the prefab companies have inventory of units sitting around waiting to be sold. Most build to order and have long lead times as demand increases and labor is hard to come by. Often it takes just as long to order and receive a prefabricated ADU as it does to custom build one on site. Hopefully this is a short term challenge and over time prefabricated units will become available in a shorter timeframe. When this is the case it will be a very compelling argument to choose a prefabricated ADU.

There are a couple downsides to Prefabricated ADUs. The primary one is that your choices for the design is limited. These ADU projects are predesigned and manufactured so you don’t have the ability to adjust the design, select different materials, and make other revisions that you may get to make if you were going a more custom route. The other challenge is that these projects show up to site as large objects that need to be moved into place, meaning often you need a crane and other large equipment to help assemble the ADU. The drawback here is that there could be site conditions that prevent prefabricated units from being viable at all. Overhead power lines, trees, steeply sloped sites, and other conditions may make your property unable to accommodate a prefabricated unit.

It is important to check with the company and share details about your property to verify if they can actually install their product on your property, and what additional installation costs may be required.

The other issue to look carefully at before moving in this direction is the cost. It is important to understand the base cost of the prefabricated parts of the project, with the additional cost required for the site specific work. You may see a prefab ADU being advertised for say $200,000 but typically that wouldn’t include things like excavation, concrete foundation work, utility installation, complications with access to the site, landscaping and other costs that you would need to incur. When comparing prices make sure you are comparing the total project costs and not just the cost of the prefabricated ADU itself. These additional costs could add thousands of dollars and maybe even $100,000 or more depending on the specifics of your property. I’m not trying to scare anyone away from exploring prefabricated accessory dwelling unit options, but know that the sticker price on a website may not be the full project cost to you.

Pre Designed ADU

Where Prefab ADUs are a fully built unit shipped and installed on site, Pre-designed ADUs are where you are simply purchasing the design drawings for an ADU project. Typically this could be a PDF file, a CAD file, or perhaps a Sketchup or BIM file like Revit or ArchiCAD. Most likely it would be a PDF of the ADU plans that you could then print, share with a local designer or engineer to make revisions, and submit for permit review at your local building department.

There are many advantages to starting your ADU project with a pre-designed plan set. It can save a significant amount of time when compared to going with a custom designed ADU project. Instead of working with a designer to start a new design from scratch you can pick a design that you like and meets your project goals and then just make some small revisions to get it ready for permit approval. We find that starting with ADU plans can save approximately 4-5 months of time.

When you save time, you also save money. Hiring a designer or architect to design a custom ADU should cost about 10% of the project budget. For a nice $300,000 ADU that would mean design fees of around $30,000. Although, this can be great value when the custom designed ADU is specific to your property, aesthetic taste, and project goals, for those who can’t afford this premium price, starting with a pre-design accessory dwelling unit can cut this fee significantly. We sell our plans for around $1,000 and often make small revisions for another $1,000 to $2,000 for our clients. You can then take the drawings to a structural engineer to complete their work for another few thousand dollars. Alltogether you can probably get a permit ready set of drawings for close to $5,000 or less. This is much more affordable for most people than going with the custom route. All of our plans are designed by talented architects and designers who specialize in ADUs, and many are award winning designs, meaning you are getting a high-quality design for a fraction of the cost of a custom ADU.

Another advantage to a pre-designed ADU is that you can get construction cost estimates done pretty early in the project. If you have engaged a general contractor already, they can probably give a good estimate of what a design would cost by analyzing the ADU design drawings and/or seeing images of other built projects with the same design. You can also ask the company selling the plans about cost estimates from other builds. Having this cost information up front can help you develop a project budget and know whether the ADU will be a good investment.

This all being said, there are many reasons why a custom ADU design could be the best approach for your project. We will explore that in the next section.

Custom Design and Built ADU

To be honest, if money wasn’t a barrier, I would recommend that everyone go with a custom designed ADU project. Hiring a skillful designer to craft an ADU design that is specific to your goals, taste, and property can give you the best result. However, it is never the case that money isn’t a factor in people’s decisions.

Custom ADU design is definitely the most expensive option of the three. It also probably takes the longest as you have to work with the designer to develop design ideas, work through iterations, and ultimately land on the best solution for the project. We typically estimate that the design process takes about 5-6 months for most of our clients. This could be longer or shorter depending on your ability to make decisions, the size and complexity of the project, and the local jurisdiction and their rules and regulations. Often there are city requirements that require additional work or bringing on other consultants that can add time and cost to the design phase. .

The other aspect of custom designed ADUs is that often people who go this route want something more unique or higher end. Even when they say they are on a tight budget, in our experience people tend to make decisions or select designs or materials that can push up the cost. My opinion is that you get what you pay for and often these decisions lead to better quality projects that are beautiful spaces to live. But it is important to consider that once you start designing, the sky is the limit and you may talk yourself into doing something higher end than what you started out imagining. This can be both a pro and a con to going with a custom designed accessory dwelling unit.

Advantages start with designing something specific to your property. Taking cues from the main house, the site topography, solar orientation, views, landscape features, neighborhood context, privacy concerns, and the taste of the owner means that a custom design project can really perform better than most other options. It allows you to make adjustments that mean the ADU can fit seamlessly into the surroundings and compliment what is already there. You can’t really get this level of site-specific advantages when going with a prefabricated ADU or a pre-designed ADU. This is also why we tend to not recommend garage conversions very often. They just limit what is possible by too much, meaning the end result is not ideal for what you could get with a fully custom, ground up construction ADU.

If you can afford it, we would highly recommend this approach. If budget is tight, that is when you should definitely start exploring the other options described above.

One of our favorite designs is this split level ADU that stacks two bedrooms while providing a light filled living space with open kitchen, living, and dining areas. The large floor to ceiling glass provides great views and natural light to flood the interior, making the smaller sized ADU feel much larger.

Features of The Best ADU Designs

What makes one ADU design better than another? Lessons learned from designing over 60 custom ADUs and offering award winning pre-designed ADUs has lead us to some fundamentals in good ADU design. Designing the best ADU for your property requires careful planning, consideration of your needs, and the help of an experienced design team. Through years of experience we have crafted beautiful and functional ADUs that are some of the best available plans on the market. In this blog post, we'll explore what makes the best ADU design.

1. Functionality and Flow

   The best ADU designs take into account the function and flow of the space. A well-designed ADU should feel spacious and open, with well-defined areas for living, sleeping, and cooking. The layout should flow smoothly from one area to another, and provide ample storage space. The design should also take into account the specific needs of the inhabitants, such as mobility and accessibility requirements. Since ADUs are smaller homes, it is imperative that their layouts are efficient and functional.

2. Energy Efficiency

   Another important aspect of the best ADU design is energy efficiency. An ADU that is built with energy-efficient materials and features can save you money on your utility bills and reduce your environmental impact. Features such as continuous insulation, low-flow fixtures, and energy-efficient appliances can help you save on energy costs, while also making your space more comfortable and sustainable. Passive strategies like sun shading, natural light, thermal mass and other features are things that a great ADU design can incorporate.

3. Integration with the Existing Property

   The best ADU design is one that seamlessly integrates with the existing property. A well-designed ADU should complement, but not necessarily mimic, the style and character of the main home, while also providing a unique and independent living space. It's important to consider the landscaping and outdoor areas when designing an ADU, so that the entire property looks cohesive and well-designed.

4. Privacy and Comfort

   Privacy and comfort are also important aspects of the best ADU design. The design should take into account the privacy needs of the inhabitants, as well as provide a comfortable and relaxing living space. This can be achieved through the use of soundproofing materials, adequate lighting, and comfortable furnishings. This is important both in terms of the interior design of the ADU, providing privacy between spaces, as well as between the ADU and the main house.

5. Flexibility and Adaptability

   Finally, the best ADU design should be flexible and adaptable to changing needs. An ADU that can be easily modified or repurposed as your needs change can save you money and hassle in the long run. The design should take into account the possibility of future modifications, such as adding or removing walls, or changing the use of the space - perhaps from a rental unit to a home office, or from a guest suite to a home for an aging parent. One of the true benefits of an ADU is that they can be used for so many things over the years.

In conclusion, the best ADU design is one that takes into account functionality, energy efficiency, integration with the existing property, privacy and comfort, and flexibility and adaptability. By working with an experienced design team, you can create an ADU that meets your specific needs and enhances the value of your property.

The design locates the large floor to ceiling windows overlooking the trees in the backyard, providing great views into nature but lots of privacy from the surrounding houses.

ADU Plans For Sale. A Great Way To Begin Your ADU Project

If you're looking to add extra space and value to your property, you may be interested in purchasing ADU plans that are for sale online. ADUs are quickly becoming popular among homeowners as a way to increase living space or generate passive income, and there are numerous benefits to building one on your property.

When searching for ADU plans for sale, it's important to understand the different types of ADUs available and which options may be best suited for your needs. The most popular types of ADUs include garage conversions, backyard cottages, and basement apartments.

Garage conversions are one of the most popular types of ADUs and involve converting an existing garage into a separate living space. Basement apartments are another popular option, which involves converting an existing basement into a livable space.

These can be affordable options for homeowners as it eliminates the cost of building a separate structure. However, they aren’t the best option for many. Not every property has a suitable garage or basement, many homeowners don’t want to lose the parking or storage space, and if the existing garage structure or basement isn’t in good condition or built to code, it could actually be more expensive to convert it into an ADU that building a new detached ADU. It is also difficult to purchase a pre-designed ADU plan for a garage or basement conversions. You will most likely have to spend more on the design fees to make a custom solution for the specifics of your garage structure or basement space.

Backyard cottages, or Detached ADUs, are standalone structures that are typically built in the backyard and can range from small studio apartments to larger two-bedroom homes. When searching for ADU plans for sale, it's important to consider factors such as size, layout, and design. Many homeowners opt for open floor plans, which create a sense of spaciousness and make the most of the available square footage. Others may prefer a more traditional layout, with separate rooms for living, dining, and sleeping. The design style of an ADU is also important, as it can impact its rental value and overall appeal.

Another important consideration when purchasing ADU plans for sale is local zoning and building regulations. It's essential to understand the requirements in your area and work with professionals such as designers, architects, engineers, and contractors to ensure that your ADU meets all necessary codes and regulations. Starting by purchasing ADU plans can save time while still working with a local expert to help with small revisions and the permitting process.

When it comes to purchasing ADU plans for sale, there are numerous resources available online. Many websites like Modern ADU Plans, offer a variety of plans to choose from, ranging from small, basic structures to larger, more complex designs. The cost of these plans can vary widely, with some plans available for a few hundred dollars and others costing several thousand dollars or more. There is also the option of starting with an ADU plan and the working with us to adapt or revise the design to meet your specific needs.

It's important to be selective when choosing a plan, and consider factors such as the size of your property, local zoning codes, your budget, and your desired outcome. You may also want to consider the potential resale value of your ADU, as this can impact your long-term investment. All of these factors can influence the appropriate project budget and the ultimate return on your investment.

ADUs As A Strategy For Passive Income

Our Personal ADU Investment Story

If you are considering adding an ADU project to your property as an investment and have any questions, don’t hesitate to reach out. I started this business to help people realize the dream of adding an ADU and starting to earn passive income through real estate investment. Althought I am trained as an architect and have designed dozens of custom ADU projects over the years, it is through building one for ourselves that really proved the power these small projects can have on improving your life and wealth.

My wife and I added an ADU to a property we owned in Portland, Oregon, converting an interior part of a house into a 1 bedroom rental unit. We rolled up our sleeves and did most of the work, from designing a compelling modern interior aesthetic, to lifting a sledge hammer to do the initial demolition work.

The original house was purchased for around $325,000 and we spent about $100,000 on the build to add the internal ADU. We did a lot of the construction work ourselves to save on labor costs - it would be been closer to $150,000 if we hired a GC to do the whole thing. We then rented the ADU for around $1,800 a month. We also rented the main house for around $2,400 per month and the rental income from the two units combined covered the full mortgage payments, maintenance costs, property management fees, and left a a few hundred dollars per month in our pocket.

After 4 years or renting out the property we moved across the country and ended up selling it for about $610,000. Overall, it was a great investment and adding the ADU was a huge part of that. We probably put in about $175,000 in cash including the down payment, property improvements, adding the ADU, and general maintenance and upkeep. Just with the sales price we earned close to a 100% return on that initial investment. Of course a hot market helped a lot, but making two cash generating rental units pushed up the sales price significantly.

ADUs Are A Great Passive Income Strategy

As the cost of living continues to rise across the country, it has become increasingly difficult for many people to afford their monthly bills and expenses or to purchase property of their own. In order to generate additional income, many people are turning to passive income strategies like investing in real estate. One real estate investment that has become increasingly popular in recent years is building accessory dwelling units (ADUs) on existing properties. This allows you to maximize the investment in your own property, and helps people afford to purchase a home by using rental income to help cover mortgage payments. In this blog post, we will explore the concept of ADUs as a strategy for generating passive income.

What Are ADUs?

ADUs, also known as accessory apartments, in-law units, or granny flats, are self-contained living spaces on the same property as a primary residence. These living spaces are typically smaller than the primary residence and can be used for a variety of purposes, such as rental units, guest houses, or additional living space for family members. ADUs can be attached to the primary residence, such as in the form of a basement apartment, or detached, such as a separate backyard cottage. In general, ADUs are great investments that can have a great ROI.

Why Build an ADU?

There are a number of reasons why building an ADU can be a smart investment strategy. One of the primary reasons is that an ADU can generate passive income in the form of rental income. Renting out an ADU can provide a steady stream of monthly income that can help cover mortgage payments, utility bills, and other expenses. Additionally, an ADU can increase the value of a property, making it an attractive investment option when considering the long term value of a property and future sales price.

Another advantage of building an ADU is that it can provide flexible living arrangements for homeowners. For example, if a homeowner has aging parents who require assistance with daily living, an ADU can provide them with a separate living space while still allowing them to be close to their family. Additionally, if a homeowner has adult children who want to live independently, an ADU can provide them with a more affordable living option. These benefits are financially positive as an ADU could be more affordable than the cost of assisted living or market rate housing in high demand cities, saving significant costs on a month-to-month basis.

How Much Income Can You Generate with an ADU?

The amount of income you can generate with an ADU will depend on a variety of factors, including the size and type of ADU, the location of the property, and the rental rates in the local market. In general, however, ADUs can be a lucrative source of passive income. According to a report from the National Association of Home Builders, the median rental income for an ADU in the United States is approximately $1,400 per month. In higher cost cities like Berkeley, Seattle, Los Angeles, or Vancouver, Canada, it is possible to rent out ADUs for over $3,000 per month. And where you can list them on AirBnB or other short-term rental sites, we have seen people earn well over $4,000 per month in revenue off a well designed ADU.

Of course, the amount of income you can generate will also depend on your rental strategy. If you choose to rent out your ADU on a long-term basis, you can expect to generate a consistent stream of monthly income. However, if you choose to rent out your ADU on a short-term basis, such as through a platform like Airbnb, you may be able to generate even more income per night, although the income stream may be less consistent from month to month.

Beyond the rental income, resale value is another aspect of investing in an ADU, although this technically is not passive income it is still important to consider at the outset of your ADU project. A 2021 study covered in Porch.com showed that homes in the western U.S. sold for about 35% higher than homes without an ADU. When combined with the rental income you can earn prior to selling a property, ADUs almost pay for themselves twice.

What Are the Costs of Building an ADU?

The cost of building an ADU will depend on a number of factors, including the size, type, and location of the unit, as well as the cost of materials and labor in your area. According to a report from the Urban Land Institute, the cost of building a detached ADU can range from $90,000 to $500,000, while the cost of building an attached ADU can range from $75,000 to $250,000. In our experience, when you combine the full cost of the project, including design, engineering, permits, utilities, site improvements, and construction, most ADU projects cost over $200,000 and could be much higher in expensive cities. Yet, this is still a strong investment.

While building an ADU can be a significant investment, it is important to keep in mind that it can also provide a significant return on investment in the form of rental income and increased property value. Additionally, there may be financing options available to help offset the initial costs of building an ADU, such as home equity loans or lines of credit.

Starting with a market analysis of the rental prices can help you work backwards to determine the maximum project budget. As a back of the envelope calculation you can spend about $100 on the development of an ADU for every $1 of monthly rent. For example, if you could rent your ADU for $3,000 per month in Berkeley, California, a comfortable project budget would be around $300,000.

This is just a general rule of thumb and not meant to replace a more in-depth financial analysis. There could be many reasons why you want to spend more than the rough estimate above. For instance if you wanted to add an amenity for the main house like a garage below the ADU, or you wanted to build a fancier unit with higher-end finishes knowing it would be more durable and have lower lifetime costs. Or perhaps you wanted to invest in super efficient systems or passive house construction to reduce energy usage, lowering the operational costs. Another reason to increase the up front investment would be to consider the resale value of the property in the future. Good design can often add 10% or more to the sales price of a property. Often going with the cheapest solution is not the best investment.

Questions to Ask Yourself When Considering an ADU as an Investment

• What are the long-term goals for the project?

• What is the local market for rental units? What is the average monthly rent for similar sized units in your location?

• How many bedrooms are ideal to maximize the rental price?
  (Typically we would see 2br units as the best option for investment ADUs)

• What do I need as a monthly ROI to make this project worth it?
  (You want it to be cashflow positive after any financing you take out to fund the project)

• What financing options are available and how much will I need to borrow?

• What is the maximum project budget for the ADU?
  (include all potential costs like design fees, engineering, surveys, permits, and construction, etc.)

• Who will manage the rental unit when it is complete?
  (There really is no such thing as truly passive income. Rental properties take time and effort to manage. Are you ready to take on this work on your own or do you want to hire a rental management company to handle it for you?)

In conclusion, ADUs can be an excellent investment for those looking for a passive income stream. They offer homeowners an opportunity to create additional space on their property while generating rental income.

To maximize the return on investment, homeowners should consider factors such as location, design, and potential rental income when deciding on an ADU project and crafting the project budget. It’s also important to be aware of local zoning and building regulations and work with experienced professionals such as designers, architects, contractors, and property managers to ensure a successful outcome.

While the initial investment may be high, the long-term benefits of owning an ADU are clear. Not only can they generate passive income, but they also increase the value of a property and can provide a multi-generational housing solution for families.

As the demand for affordable housing options continues to rise, ADUs will continue to be an attractive investment for homeowners looking to generate passive income while also contributing to their local communities. By taking advantage of the benefits of ADUs, homeowners can build a secure financial future for themselves and their families.

ADU Design Guidelines: Maximizing Living Space Efficiency

Accessory Dwelling Units (ADUs) have gained significant attention as versatile living spaces that offer homeowners various benefits. Whether it's accommodating family members, generating rental income, or creating a home office, ADUs play a crucial role. In this comprehensive guide, we'll delve into the importance of thoughtful ADU design, with a specific focus on maximizing living space efficiency. We'll also highlight the advantages of using pre-designed ADU plans in simplifying the design process and saving valuable time.

The Role of Living Space in ADUs:

ADUs are all about providing functional living spaces. These spaces can encompass living rooms, bedrooms, and multipurpose areas, making them versatile and adaptable to different needs. Whether you're housing family members or renting out the ADU, the design of the living space plays a pivotal role in making the unit comfortable and appealing.

Local ADU Regulations and Zoning Requirements:

Before diving into ADU design, it's essential to understand local regulations and zoning requirements. These regulations can significantly impact the design of your living space. Factors such as setback requirements, size limitations, and zoning considerations must be taken into account to ensure compliance. Call your local building department or read your local ADU zoning code to learn about the restrictions in your area. Once you understand the overall size limitations you can then start considering how to divide the area of the ADU into adequate living spaces.

Advantages of Using Pre-Designed ADU Plans:

Designing an ADU can be a complex process, especially if you're starting from scratch. However, pre-designed ADU plans offer several advantages:

1. Streamlined Process: Pre-designed plans simplify the design process by providing a comprehensive blueprint. You won't need to spend extensive time on custom design, reducing project delays.

2. Expertise: These plans are crafted by experienced designers who understand the nuances of ADU design and construction. You can trust that the design is optimized for efficiency and functionality.

3. Efficiency: Pre-designed plans are carefully created to maximize every square foot of living space. This efficiency is essential for creating a comfortable and functional ADU.

Maximizing Living Space Efficiency:

Efficient space planning is key to ADU design. Consider the following strategies:

1. Open Floor Plans: Open layouts create a sense of spaciousness and flexibility. They're ideal for making the most of limited square footage.

2. Multifunctional Areas: Design living spaces that serve multiple purposes. For example, a fold-down bed can transform a living room into a bedroom.

3. Natural Light: Maximize natural light with large windows and strategically placed skylights. This not only brightens the space but also makes it feel more spacious.

4. Smart Storage: Incorporate built-in storage solutions to minimize clutter and maximize usable space.

5. Small Bedrooms: with smaller overall sizes for ADUs than main houses, it is important to allocate the right amount of space for each function. We recommend smaller bedrooms, and larger living rooms to give more space to the places you spend the most time while awake.

6. One Bathroom: WIth limited square footage it is better to have larger kitchens and living areas than to have multiple bathrooms. If you really must have a second bathroom, consider only a 1/2 bath.

ADA Compliance and Accessibility:

Creating ADU layouts that consider ADA guidelines is essential for creating accessible ADU living spaces that are ready for aging-in-place. This includes features like wider doorways, accessible bathrooms, and proper ramp access. These design considerations ensures that your ADU can accommodate a wide range of occupants comfortably and can set your ADU apart from others in your rental market.

Interior Finishes and Aesthetics:

Interior finishes play a crucial role in enhancing the overall appeal of your ADU living space. Consider these factors:

1. Materials: Choose durable and visually appealing materials that align with your design preferences.

2. Color Palettes: Use colors strategically to create a sense of continuity and spaciousness. We tend to stick to white, light gray, and neutral colors that can compliment a wide range of styles.

3. Design Styles: Select design styles that resonate with your tastes while maintaining a cohesive look. We think modern styles are in higher demand on rental markets and can demand higher rental rates.

Designing ADU living spaces that are both efficient and comfortable is a rewarding endeavor. By maximizing every square foot, ensuring ADA compliance, and carefully selecting interior finishes, you can create a space that serves your needs seamlessly. Consider the advantages of using pre-designed ADU plans, which streamline the design process and save valuable time. With thoughtful planning and the right resources, your ADU can become a functional and inviting living space that enhances your property's value and functionality.

Garage Conversion vs. New Construction: Choosing the Best ADU Option

Are you considering converting your garage into an accessory dwelling unit (ADU)? It's a popular choice among homeowners who want to create more living space on their property and already have a garage structure in place. However, while converting a garage into an ADU can be a tempting option, it may not always be the best choice. In this blog post, we'll explore the pros and cons of garage conversion versus new construction for an ADU.

First, let's define what an ADU is. An ADU is a self-contained living unit that is added to a property's existing structures. ADUs are becoming increasingly popular in many cities as a way to address the housing shortage and provide additional living space for homeowners or rental income.

When it comes to converting a garage into an ADU, there are several advantages. The existing structure of the garage means that the foundation and framing are already in place, which potentially can save time and money compared to building from scratch. In addition, many garages already have utilities such as electricity and plumbing connected, which can also save on costs. We say potentially because starting with an older garage where the foundation, framing, siding, or roof are in poor shape could actually cost more to repair than building a completely new ADU from the ground up.

However, there are also several disadvantages to converting a garage into an ADU. For example, most garages are not designed with the same level of insulation as a living space, which can result in higher heating and cooling costs. Garages may also not have enough natural light, which can make the space feel dark and cramped. You could add windows and doors to bring in more light of course, but often older garages are built on property lines that may limit the ability and location where windows can be added. Additionally, converting a garage may not always be possible due to zoning regulations or structural limitations.

Another drawback is that often garages don’t have the utility hookups that will be required. Water, sewer, and electrical connections could require you to cut up existing foundations or slab within the garage in order to get the utilities to the right places. This isn’t a deal breaker, but is a costly part of the conversion process.

On the other hand, building a new ADU from scratch can offer several advantages. For one, a new ADU can be designed specifically for living, with features such as proper insulation, natural lighting, and more spacious layout. A new construction ADU can also be designed to match your aesthetic taste, or the style of the existing home and be tailored to the needs of the homeowner or potential renters. Additionally, new construction ADUs are often larger than converted garages, providing more living space and potentially increasing rental income and property value.

While building a new ADU may seem like a more expensive option at first, it's important to consider the long-term benefits. A new construction ADU is likely to have a longer lifespan than a converted garage, which may require more maintenance and repairs over time. And when you consider energy efficient design and construction the new ADU will probably be much cheaper to operate on a monthly basis with lower utility bills. A new ADU can also potentially increase the value of your property more than a converted garage, which can be especially important if you plan to sell in the future.

In conclusion, while converting a garage into an ADU may seem like an attractive option, it's important to carefully consider the pros and cons before making a decision. In many cases, building a new ADU from scratch may offer more long-term benefits and be a better investment for homeowners. Ultimately, it's important to work with a trusted advisors, designers, and builders to explore all of your options and make an informed decision based on your unique situation and goals.

We are happy to answer questions and help advise you on the right path to adding an ADU based on the specifics of your property and your personal project goals. Please reach out to tell us about your ideas and we will do our best to help in any way we can.

ADUs in the News: "Senior Housing that Seniors Actually Like" in the New York Times

The New York Times recently published a great article discussing how ADUs are a great option for elderly housing - whether moving into an ADU as you age or even building them for adult children to be close by. Multi-generational living can have tremendous benefits, and building an ADU can be a lot more affordable than renting in a retirement community. It is great to see that ADUs are growing in popularity across the country.

We have been designing ADUs for almost 10 years now, and housing for elderly people is one of the main reasons our clients have decided to pursue adding an Accessory Dwelling Unit to their property. Some were younger couples building an ADU for an aging family member to live (It is enticing to have some on-site childcare from grandma). While others were building an ADU designed for aging-in-place and barrier free living so they could downsize yet stay in the community they have grown to love. In this case, renting out the main house generated income for retirement and more than offset the cost of building the ADU.

Regardless of the reason, ADUs are great options for senior housing as it keeps them engaged in the community, brings them closer to family, and is often much more affordable than renting in a retirement community.

It is great to see communities across the country embrace ADUs as a great housing option. They won’t solve housing shortages along, but are a step in the right direction and can help provide a more diverse range of housing to address issues like senior living.
