Accessory Dwelling Units (ADU) and Junior Accessory Dwelling Units (JADU)  

In response to the Bay Area’s regional housing shortages, the State of California adopted legislation (SB 13, AB 68, and AB 881) to encourage the construction of Accessory Dwelling Units (ADU) and Junior Accessory Dwelling Units (JADU) by reducing the regulatory barriers commonly found in local zoning ordinances.  Please click on the following link to view the ADU Regulations:

Code Section 25.48.030 - Accessory Dwelling Units

For an overview of the ADU requirements, including FAQs (frequently asked questions) and development standards, please visit our Accessory Dwelling Unit Guidelines


Review and Approval Process:
The approval process for ADUs and JADUs is ministerial (neighborhood notification is not required if they comply with all ADU requirements).  However, you will be required to file an application for an ADU Permit with the Planning Division.  Once the ADU Permit is approved, you may then submit an application for a building permit.
