Is an ADU a Good Investment?

Whether an ADU (accessory dwelling unit) is worth the investment will depend on a variety of factors, including your specific circumstances, the local real estate market, and the costs and benefits of building an ADU. In general, we have found that they have been great investments for most of our clients.

There are several potential benefits to building an ADU, including:

  • ADUs Provide Rental Income:

    An ADU can provide a source of rental income for property owners. By adding an ADU to their property, property owners can rent out the space to generate additional income. This can be especially useful for property owners who have a large amount of unused space on their property or who are looking for a way to supplement their income and help pay down their mortgages.

  • ADUs Increase Property Values:

    An ADU also increases the value of your property. By adding additional living space, property owners are effectively increasing the overall built square footage of their property, which can make it more valuable. This can be a particularly good investment for property owners who are planning to sell their property in the future, as the added value of the ADU can increase the sales price when they are ready to sell.

  • ADUs Are A More Affordable Housing Option:

    ADUs also provide a more affordable housing option for homeowners who want to add additional living space to their property. Because they are typically smaller than traditional homes, ADUs can be less expensive to build and maintain. This can be especially appealing for homeowners who want to add a separate living space for family members but want to save money compared to purchasing a full house.

However, there are also several potential drawbacks to building an ADU, including:

  • Initial ADU Cost:

    Building an ADU can be a significant investment, as it requires the purchase of materials, labor, and any necessary permits and fees. This initial cost can be a significant financial burden for some property owners and/or require construction loans or refinancing of the main house to cover those costs. It is important to balance the cost with potential income or increased property values. Overall, we see most detached ADUs starting at an investment of around $200,000 or more. Check to see if rental income in your area will offset the initial investment and make it worth pursuing. In most larger cities rent is high enough to make it a good investment despite the initial costs of ADU construction.

  • Ongoing ADU Costs:

    In addition to the initial cost of building an ADU, there may also be ongoing lifecycle costs associated with maintaining the unit, such as utilities, insurance, and any necessary maintenance and repairs. These costs should be considered when evaluating the potential profitability of an ADU - balancing these costs with potential rental income.

  • ADU Zoning and Legal Issues:

    Depending on the location of the property, there may be local zoning laws or other legal restrictions that impact the ability to build an ADU or what you can do with it (for instance many cities ban renting ADUs as short term rentals like Airbnb). It is important to research and understand these laws and regulations before embarking on an ADU project.

Overall, whether an ADU is worth the investment will depend on a variety of factors and should be carefully evaluated on a case-by-case basis. However, in our experience most ADUs are excellent investments for homeowners as the potential rental income plus the increase in property values more than offsets the upfront and lifecycle costs.
