Full Breakdown

Sonoma County adopts the 2022 California Electrical Code (CCR Title 24, Part 3) by reference under Sonoma County Code § 7-13(A)(4), then locally amends CEC Section 105.2 to spell out what electrical work is exempt from a permit. Everything else, new circuits, panels, fixed wiring, and most new installations, needs a permit from the Permit and Resource Management Department before work starts. The only exemptions are minor repairs such as lamp replacement, reconnecting approved portable equipment to existing receptacles, temporary decorative lighting, reinstalling attachment-plug receptacles, repairing branch-circuit overcurrent devices in the same location, and communications wiring.

Violations & Fines

Doing exempt-list electrical work without a permit violates Sonoma County Code § 7-13; the chief building official can order a stop-work and assess a review fee equal to the permit fee under § 7-13(B)(4)(6).
