Accessory Dwelling Unit Regulations

State Law and ADU Ordinance Update

In 2017 and 2019, the State legislature amended Government Code §65852.2 and added Government Code §65852.22 to ease development standards and facilitate the construction of Accessory Dwelling Units (ADUs) and Junior Accessory Dwelling Units (JADUs).

On November 10, 2020, City Council adopted amendments to the Inland Zoning Ordinance Title 30 subsection §30.185.040 Accessory Dwelling Units, effective on December 10, 2020. Council also adopted amendments to the Coastal Zoning Ordinance Title 28 new Chapter 28.86. The Title 28 amendments are not effective for the Coastal Zone until certified by the California Coastal Commission and accepted by City Council, anticipated in 2021. In the meantime, ADU projects in the Coastal Zone will be reviewed under State law regulations.
