Permitting in California, explained
Every set submitted in California must be stamped by an architect licensed by the California Architects Board. Beyond licensure, the state layers requirements few other jurisdictions do: mandatory Title-24 energy compliance, seismic detailing tied to the local hazard zone, and — in much of the state — wildfire (WUI) ignition-resistant construction. These aren't optional line items; a set missing them is rejected at plan check.
On top of state rules, each city and county adds its own review. Coastal jurisdictions trigger Coastal Commission steps, hillside lots require additional geotechnical and structural coordination, and historic districts add design review. Our jurisdiction database scores each of these so your estimate reflects the real complexity of your specific address, not a statewide average.
