ADU guide

What Is an ADU

An accessory dwelling unit is a separate living space with facilities for daily living. A garage can be considered for conversion, but not every garage room is a separate dwelling.

Requirements depend on your property and the agency reviewing it. Confirm current details with that agency before finalizing plans.

Questions to consider

  • Clarify whether the planned space will be a room in the home or a separate unit
  • Consider access, cooking facilities, bathroom, and utility connections
  • Compare the City and County guidance for the jurisdiction responsible for the address
  • Ask a qualified professional to assess the existing garage and proposed use

Common questions

Can a garage become an ADU?

A garage may be a candidate for conversion. The reviewing agency and project professional can evaluate eligibility and the required work for the address.

Is a studio automatically an ADU?

No. A workspace or studio may not be a separate dwelling. Describe how you plan to use it and what facilities it will have to the reviewing agency.
