All California jurisdictions.
GSPE supports permit research and coordination statewide. Our jurisdiction directory covers all 58 California counties and the state’s incorporated cities and towns, helping clients identify the correct building, planning, sign, public works, and outside-agency approval path.
Find any California county, city, or town.
Search the statewide directory or choose a county. For unincorporated properties, the applicable county is generally the primary local permitting jurisdiction. Incorporated locations are typically administered by the city or town, with additional county, state, regional, fire, utility, airport, coastal, or transportation agencies involved when required by the project.
Send the project address, APN, or city. We can confirm the responsible jurisdiction, likely permit path, required departments, and outside-agency coordination based on the actual project scope.
Ask About Your JurisdictionThe incorporated-city directory is loaded from California public jurisdiction data maintained by the California Department of Technology using California Department of Tax and Fee Administration city/county boundary information. County coverage includes all 58 California counties. Jurisdiction names and boundaries may change; GSPE confirms project-specific requirements during research.
Coverage does not mean every project has identical requirements. Permit rules vary by location, project scope, zoning, code cycle, site conditions, fire authority, utilities, special districts, and other agency overlays. GSPE verifies the current process for each project before submittal.
