List of California City / County ADU Requirements

Here is a list of California City and County ADU regulations specific for each area.  Many areas still default to the recent California memorandum regarding Accessory dwelling units and granny flats.

additional planning information from a specific city or county can be found on the pages listed below.

If you can’t find the city or county you are looking for, you can contact your city / county building department and locate the information that way.

If you have links to city and county information that are missing from the list below, please use the comment function at the bottom of this page so we can add it to our list.  Thank you!
