Accessory Dwelling Units are permitted in accordance with Ordinance No. 1021, adopted by the Brentwood City Council. These types of projects must be allowed under California Senate Bill (SB) 13 and California Assembly Bill (AB) 68, which were signed into law by Governor Newsom on October 9, 2019 and took effect on January 1, 2020.

Accessory Dwelling Units (ADUs) and Junior Accessory Dwelling Units (JADUs) are allowed in single-family and multi-family residential zoning districts, in accordance with specific standards and conditions. ADUs may be constructed as new units separated from the main home, as long as they adhere to setback requirements. They may also be attached to or located within the existing home and, in some circumstances, ADUs may be constructed within an existing garage or within an existing outbuilding on the property.

To initiate an application to construct an ADU or a JADU, please submit a Building Permit Application and all required materials.
