Project Background 

An Accessory Dwelling Unit (ADU) is a separate, self-contained small living unit with bathroom and kitchen facilities located on the same lot as the single family residence. It can be either detached from or attached to the primary residence with a separate entrance. A Junior Accessory Dwelling Unit (JADUs) is a unit with approximately 500 square feet of living space contained entirely within an existing single-family structure. 

In response to the Bay Area’s regional housing shortages, Governor Brown signed three new laws (SB 1069AB 2299 and AB 2406) in September 2016 to encourage the construction of ADUs and JADUs by easing the regulatory burdens and barriers of existing local laws. In response to these new state policies, the Palo Alto City Council adopted a new ADU and JADU ordinance on May 8, 2017. This ordinance became effective June 8, 2017. The City is currently studying options to update this ordinance.

Please note that ADUs are permitted in all residential zoned districts, including the Single Family Residential (R1) District.
