Bay Area ADU Regulations for Permit Application

Based on what could be permitted on your property, we can assist you in considering the options available for creating an ADU on your parcel. Here are some of the critical regulations governing ADU construction in the Bay Area:

ADUs are allowed in most residential lots

ADUs are allowed on most residential lots as long as they meet specific zoning requirements; local zoning ordinances may restrict the number of ADUs permitted on a lot, as well as their size and location.

 

Permissible ADU square footage

ADUs can be up to 1200 sq. ft. for detached units and up to 50% of the existing living area for attached units. For instance, if your primary dwelling is 2000 sq. ft., you can have an ADU of up to 1000 sq. ft.

Permissible ADU square footage

Additional parking

One parking space on site is required for the ADU unless the ADU is within half a mile of public transportation or if the ADU is part of the primary dwelling or an existing accessory structure.

 

Your property’s zoning

For ADU to be permitted on your property, it must be zoned for residential use and mixed-use districts. Both ADU and junior ADU may be allowed on one lot.

 

Lot size

The size of your property can impact your ability to build an ADU. Local zoning ordinances may restrict the maximum number of units permitted on a lot and their size. For example, some cities within the Bay Area may limit the total square footage of all structures on a lot, impacting your ability to build a detached ADU.

Some ADUs may have yet to be eligible for permits under prior zoning regulations; with updated rules, many may now qualify for permits subject to the Bay Area code regarding site standards, environmental reviews, and utility connections for your unit to be legal.

The layout of your property may impact your ability to build an ADU; for example, if the property has limited space, finding a place for ADU can be challenging. Additionally, if your property is located on a steep slope or has other topographical challenges, it may be more difficult to build an ADU.
