Can I build an Accessory Dwelling Unit (ADU)?

Accessory Dwelling Units (ADU) and a Junior Accessory Dwelling Unit (JADU) may be allowed accessory to a primary residence in residential, mixed-use, and agricultural and resource zoning districts. ADUs may be permitted on lots with a primary residence, which may be either a single-family home or multi-family residential building. JADUs may only be constructed out of existing or proposed space within a single-family residence.

ADUs are prohibited on parcels subject to Williamson Act contracts and on parcels within the Z (Accessory Dwelling Unit Exclusion) Combining District.

Note that short-term/vacation rentals are not allowed in ADUs under any circumstance.

As with all development, code-compliant access, water supply, and adequate wastewater disposal either onsite with a private septic system or through public utilities are required. Please visit the Accessory Dwelling Unit page for a complete list of development standards, fee information, and links to more information.
