Summary
La Mesa enforces the California Electrical Code, 2025 Edition, incorporating the 2023 National Electrical Code, adopted under LMMC § 14.10.010. The Uniform Administrative Code (Chapter 14.11) requires a Chief Building Official permit for most electrical work, and the local exemption list covers only a few minor installations. Unpermitted electrical work draws an investigation fee and can be charged as a misdemeanor.
There is hereby adopted by the city of La Mesa for the purpose of operation and maintenance of all electrical wiring and electrical apparatus of any nature, whether inside or outside of any building, the California Electrical Code, 2025 Edition (Part 3, Title 24, California Code of Regulations), incorporating the National Electrical Code, 2023 Edition, published by the National Fire Protection Association. There is one copy of said Code on file in the office of city clerk for use and examination by the public as required by law.
Full Breakdown
The City of La Mesa adopts the California Electrical Code, 2025 Edition (Part 3, Title 24, California Code of Regulations), incorporating the National Electrical Code, 2023 Edition published by the National Fire Protection Association, under LMMC § 14.10.010, governing operation and maintenance of all electrical wiring and apparatus inside or outside any building. A copy is kept on file with the city clerk. Permitting runs through the Uniform Administrative Code at Chapter 14.11: § 14.11.040 (UAC § 301.2.1) lists the narrow set of jobs that need no building permit, and only a few brush against electrical work, such as antennas supported on the roof, and light standards, flag poles and antennas not over 35 feet in height above finish grade when fully extended; the same section warns that unless otherwise exempted, a separate electrical permit is still required for exempted building items.
Fees are set under the City Council's fee resolution per § 14.11.070, with plan review billed at 65 percent of the permit fee, and a permit expires under § 14.11.050 if work is not commenced within one calendar year, is stopped for six calendar months, or runs past three calendar years. Electrical work started without a permit triggers the § 14.11.070 investigation fee, equal to the permit fee, before the Chief Building Official will issue one, and the Chief Building Official may deny any permit under § 14.11.060 where the property already has an unsafe or substandard building violation on record.
Violations & Fines
Violating the electrical permit requirement or any technical code adopted under Chapter 14 is a misdemeanor under § 14.11.030: up to a $500 fine, up to six months in county jail, or both, with each day of continued violation counted as a separate offense. Unpermitted electrical work also draws the § 14.11.070 investigation fee equal to the permit fee.
