ADU-image

Accessory Dwelling Units (ADUs) offer a variety of benefits to communities. They help increase housing supply, provide an affordable housing option for many low- and moderate-income residents, allow elderly and/or disabled persons live independently yet close to family members or caregivers, and benefit homeowners by providing extra income that can assist in mitigating the cost of living. 

In September 2016, Governor Jerry Brown signed into law Senate Bill (SB) 1069 and Assembly Bill (AB) 2299, intended to streamline the approval process for ADUs. In addition, the City has chosen to adopt further changes intended to help streamline the approval process, encourage the use of ADUs to help the City meet its housing goals, and ensure quality development in the City’s residential neighborhoods. These changes include: 

  • Establishing a minimum ADU size of 200 square feet;
  • Increasing the maximum allowable detached ADU size to 1,200 square feet, and the maximum allowable attached ADU size to the lesser of 1,200 square feet or 50 percent of the legally-established primary dwelling floor area (lot coverage maximums still apply);
  • Eliminating parking requirements for ADUs which are either:
    1. located within one-half mile of a public transit stop (based on the actual walking route between the ADU and the transit stop rather than on a straight line between the two points);
    2. located within an architecturally and historically significant historic district;
    3. located entirely within the existing principal residence or an existing habitable accessory structure, resulting in no net addition of habitable floor area on the property;
    4. in an area where on-street parking permits are required but not offered to the occupant of the ADU; or
    5. when there is a car share vehicle located within one block of the ADU.
  • Requiring a minimum private storage area of 200 cubic feet;
  • Specifically requiring all ADUs provide kitchen and sanitation facilities separate from the main dwelling unit; and
  • Requiring all new ADUs be registered to the Residential Rental Inspection Program (RRIP).

The City has prepared an Accessory Dwelling Unit Manual to help homeowners learn more about ADUs and assist them in the process of developing one. This Manual includes information on designing, developing, and renting ADUs, and can be downloaded here.

If you are interested in constructing an ADU on your property, we recommend your first step be to contact Planning Staff to discuss zoning and development requirements. Staff may be reached by phone at (925) 252-4920. Staff is also available in-person at the front counter Monday-Friday, from 8:00 a.m. to 12:00 p.m., and 1:00 p.m. to 5:00 p.m.
