I want to build an Accessory Dwelling Unit (ADU) on my property. What are the requirements and process?

All residential properties are allowed one ADU of at least 800 square feet.   Depending on lot size and capacity, an ADU may be as large as 1,000 square feet. In addition to an ADU, single-family residences may also have a Junior Accessory Dwelling Unit (JADU). A JADU is created within the walls of a single-family residence and may share restrooms with the primary residence, and must contain a basic kitchen. JADUs are allowed up to 500 square feet. Please visit Development Code Section 22.42.120 for additional ADU requirements. 

Once you have plans ready, you may submit through the Planning inquiry form. No additional forms are required at this stage. Please allow a few days for the Planning and Building and Safety Divisions to review for completeness. Once authorization is received, a planner will assist you on the next steps for formal building plan check submittal to the Building and Safety Division. There is a 15-working day turnaround once accepted by the Building and Safety Division. Every subsequent submittal is 10 working days. When all comments/corrections have been addressed, your permit will be issued for the ADU.
