Electrical Permits: Brentwood vs Concord

Most electrical work in Brentwood requires a permit from the Building Division under the California Electrical Code (Title 24, Part 3), which adopts NFPA 70 with California amendments. Permits are required for new circuits, service upgrades, panel replacements, and most hardwired installations. Like-for-like replacement of receptacles, switches, and fixtures typically does not require a permit.

Concord requires electrical permits under the California Electrical Code (CEC) for most electrical work beyond like-for-like replacement of switches, receptacles, and fixtures. New circuits, service upgrades, panel changes, EV charger installations, solar interconnections, and any work in wet or hazardous locations require a permit and inspection by the Concord Building Division. Unpermitted work can trigger stop-work orders and mandatory tear-out.
