Accessory Dwelling Units

In 2017, the state amended Government Code Section 65852.2 regarding Accessory Dwelling Units (ADUs) and added Government Code Section 65852.22 to provide a unique option for Junior ADUs, which is a unit up to 500 square feet in size contained within an existing home.  

On May 15, 2018, City Council adopted Ordinance No. 5834 (effective date: June 14, 2018) amending Title 30 of the Municipal Code, The Zoning Ordinance, to adopt local development regulations related to ADUs and Junior ADUs (adding Municipal Code Section 30.185.040); and Resolution No. 18-030 approving the ADU Covenants (deed restrictions enforcing terms regarding sale, rental, and owner occupancy) as to form.

In October 2019, Governor Newsom signed new housing bills including several that further amended Government Code 65852.2 and 65952.22, effective January 1, 2020. The City is currently reviewing the new laws and determining what amendments to Title 30 Section 30.185.040 Accessory Dwelling Units may be necessary for compliance. The City’s current ADU regulations still apply in 2019.

The City’s ADU ordinance does not apply in the Coastal Zone because Title 30 has not been submitted to the California Coastal Commission for certification. Therefore, the provisions of Government Code 65852.2 and 65852.22apply in the Coastal Zone until Title 30 is certified by the California Coastal Commission. A proposed ADU may require a Coastal Development Permit (CDP) depending on the project type.
