Accessory Dwelling Units - ADUs
Accessory Dwelling Units:
What is an ADU?
ADUs have been an effective way of incorporating smaller living units into the fabric of the community that are affordable to a wider range of income levels, including elderly family members.
Changes in State Law
Due to the housing shortage in California, the State Legislature has passed significant housing-related laws in the past three years. In 2019, the legislature passed over 20 bills intended to fast-track housing production – including accessory dwelling units (ADUs).
Updates to State Law expands areas and conditions under which ADUs can be built. The ADU Ordinance and ADU Handout both reflect the regulations permitted by new state law, effective January 1, 2023. Be advised that this information is subject to change, as state guidelines and interpretations are typically issued after the enactment of the new law. We have created an interactive map to help determine ADU parking requirements.
