Antioch, CA Building Safety: Electrical Permits (2026)

The City of Antioch Building Division issues electrical permits under the California Electrical Code (CEC), which is Part 3 of Title 24 of the California Code of Regulations, based on the 2023 National Electrical Code with California amendments. Permits are required for: new electrical service installations; service upgrades (e.g., 100A to 200A panel); sub-panel installations; new circuits for appliances, EV chargers, HVAC, or outlets; rewiring of existing circuits; installation of generators, solar panels, or battery storage; and low-voltage systems in some cases. Minor repairs like replacing a like-for-like outlet, light fixture, or switch generally do not require a permit. Homeowners performing work on their own owner-occupied, single-family residence may pull permits themselves and perform the work under California Business and Professions Code Section 7044 (homeowner exemption), but they must sign an affidavit and the home cannot be sold or offered for rent for at least one year after the work. All other electrical work must be performed by a C-10 licensed electrical contractor. Required inspections typically include: rough/wiring inspection before drywall; service/panel inspection; and final inspection after cover plates and fixtures are installed. EV charger installations (Level 2) require a permit and typically trigger load calculations; Antioch participates in streamlined EV charger permitting under AB 1236. Solar and battery permits are processed under SB 379 streamlining rules, generally within 3 business days for standard systems. Working without a permit is a code violation subject to double-permit fees, stop-work orders, and potential demolition of non-compliant work. Unpermitted electrical work also affects home insurance and resale value.
