Getting a Building Permit in Stockton
Stockton is the county seat of San Joaquin County, and building permits for residential projects are issued through the City of Stockton Community Development Department. We prepare plans for submittal to the local building department and manage the plan check process through approval.
Our process includes a site visit and measurements, design, construction drawings, structural and Title 24 energy coordination, submittal, and corrections. Stockton has a diverse housing stock — older Craftsman and Victorian homes near downtown, mid-century ranches in established neighborhoods, and newer subdivisions in the north and south. ADU and garage conversion projects are increasingly common as homeowners look to add rental income or accommodate extended family.
We also work with clients in Lodi, Tracy, Manteca, Ripon, and other communities in San Joaquin County.

Frequently asked questions
Do I need a permit for a garage conversion in Stockton?

Yes. California state law permits ADUs on most single-family and multifamily lots, and Stockton has adopted local ADU standards consistent with state law. Detached ADUs, attached ADUs, and junior ADUs are all possible depending on your property. We can review your lot and advise on feasibility.
