A. Notwithstanding any other provisions of this code, the development of ADUs and JADUs is permitted on all lots zoned for residential or mixed-use development with the following provisions and exceptions as outlined in this code.

B. An ADU or JADU must be located on a lot developed with or proposed to be developed with one or more residential units and on the same lot as a single-family residence, multifamily structure, or mixed-use building.

C. If an ADU is proposed on a lot located in the coastal zone, the ADU shall be sited and designed to avoid adverse impacts to coastal resources, including by conforming with all applicable local coastal program policies and standards, including those that govern wetlands, streams, environmentally sensitive habitat areas, public views, public access, and coastal bluffs. ADUs and/or JADUs shall not be permitted in existing buildings or structures that are nonconforming as to coastal resource protection policies or development standards of the local coastal program.

D. To protect against wildfires, maintain necessary defensible space around existing structures, and allow for better egress in an emergency, no ADUs shall be permitted in areas within designated very high fire hazard severity zones; however, JADUs are allowed. Within the very high fire hazard severity zones, for ADU applications submitted on or before May 13, 2022, an ADU shall be permitted upon satisfying all other requirements of this title. If the very high fire hazard severity zones are modified after an ADU application is submitted for a property not previously contained in the very high fire hazard severity zone, then the ADU may be permitted upon satisfying all other requirements of this title. ADUs that fall under subdivision (e) as provided for in Government Code Section 65852.2 are exempt from this requirement. (Ord. No. 2022-011, § 5, 8-1-22; Ord. No. 2022-024, § 4, 12-5-22; Ord. No. 2023-009, § 6, 10-23-23)
