Permits & licenses in Contra Costa County.
Outside every city line in Contra Costa County, the building permit, the plan review and the inspection belong to the county. California writes one code for the whole state — Title 24, the California Building Standards Code, republished by the Building Standards Commission every three years — and state law hands its enforcement to local government: the county's department on the unincorporated land, each city's department inside its own line. Hospitals answer to HCAI and public schools to the Division of the State Architect, not to either building counter.
- The Department of Conservation and Development issues building and planning permits for unincorporated Contra Costa County; filings and construction plans run through the county's ePermits Center.

How it moves
Your package is reviewed against the current Contra Costa County submission requirements before it's filed — forms, editions, scales, signatures. Then it's tracked in the queue and carried through comments. A resubmittal means the back of the line; the pre-filing review is there to help keep you out of it. The habit comes from volume: the team has processed 400+ permits annually across Maryland, D.C., and Virginia counters.
