Summary

Fairfield enforces the 2025 California Electrical Code, based on the 2023 National Electrical Code, under Municipal Code § 5.2.6. Local amendments let the chief building official cut power to a dangerous building, restrict temporary service to active construction permits, and force replacement of Federal Pacific or Zinsco electrical panels whenever electrical work is proposed on a property carrying one.

Adopt the California Electrical Code (CEC), 2025 edition, based on the 2023 National Electrical Code as published by the National Fire Protection Association (NFPA) and as adopted by the State Building Standards Commission in the California Code of Regulations, title 24, part 3. ... Section 110.2.1 – Unsafe electrical panels. Any Federal Pacific or Zinsco electrical panels shall be replaced when any work is proposed on the electrical system. The city may also require investigation or replacement of any electrical system or component where there is evidence of potential issues with the electrical system.

Full Breakdown

7 amends it in three ways. 1, the chief building official may withhold or disconnect electrical power from any building the code defines as dangerous, or where another hazardous condition exists, without waiting for a separate abatement process. 2 limits temporary electrical service to periods when a valid construction or repair permit is active, or when a project's conditions of approval specifically authorize temporary service, so a temporary hookup cannot outlive the permit it was tied to. 3 is Fairfield's targeted safety fix for two recalled panel brands: any Federal Pacific or Zinsco electrical panel found on a property must be replaced whenever any work is proposed on that property's electrical system, and the city can independently require investigation or replacement of any electrical component if there is evidence of a problem, even outside a permitted project.

3 for residential projects, though commercial and industrial jobs can pull a separate electrical permit. Permits issued under the electrical code carry the same one-year expiration and extension rules as building permits generally.

Violations & Fines

Violating the Electrical Code carries the same penalty structure as the rest of the Building and Housing Code: a misdemeanor punishable by a fine up to $2,000, up to six months in county jail, or both, with a first offense eligible to be charged instead as an infraction carrying a fine up to $500 per day. Work started without a required electrical permit also triggers an investigation fee billed at the building division's hourly rate.

Frequently Asked Questions

Does Fairfield require replacement of old electrical panels?
Yes, for two specific brands. Under § 5.2.7.3, any Federal Pacific or Zinsco electrical panel must be replaced whenever any work is proposed on that property's electrical system, and the city can require broader investigation or replacement if there's evidence of other electrical problems.
Can I get temporary power before my project is finished?
Only while a valid construction or repair permit is active, or if your project's conditions of approval specifically authorize it. Section 5.2.7.2 does not allow temporary electrical service to continue once the underlying permit expires.
What electrical code does Fairfield enforce?
The 2025 California Electrical Code, which is based on the 2023 National Electrical Code published by the National Fire Protection Association, adopted by the City under § 5.2.6 with local amendments in § 5.2.7.
