Full Breakdown

Municipal Code Section 5-9-101(3) adopts, by reference, the 'California Electrical Code, 2025 edition with errata (Title 24, Part 3, California Code of Regulations), based on the 2023 National Electrical Code, as published by the National Fire Protection Association,' as part of the City's Building Code Regulations under Ordinance No. 25-26 (Exhibit A), effective November 12, 2025. 3 states that 'permits are required for installations described in all codes adopted by reference unless specifically exempted by these codes or by the building official, in writing, for proper cause,' meaning electrical work needs a permit unless it falls under a listed exemption.

3 lets the building official charge an investigation fee if work starts before a permit is pulled. 1(D), requiring that 'all outside wiring on private property shall be underground,' with a narrow exception for temporary construction wiring installed under Section 590. That local underground-wiring rule applies City-wide to new private outside wiring, going beyond the base NEC text adopted at 5-9-101.

Violations & Fines

Electrical work is enforced under the Building Code's general violation provisions. Section 5-9-213 makes it a misdemeanor to install or alter electrical systems in conflict with the adopted codes or without a required permit, with each day of continuing violation treated as a separate offense punishable by fine or imprisonment. The City can also recover investigation costs, attorneys' fees, and cleanup expenses under Section 114.5.

Frequently Asked Questions

Which electrical code does Irvine enforce?
Irvine adopts the 2025 California Electrical Code, based on the 2023 National Electrical Code, under Municipal Code Section 5-9-101(3), effective November 12, 2025. The City then layers its own amendments on top in Section 5-9-403, most notably a rule requiring new outside wiring on private property to run underground rather than overhead.
Is a permit required for every electrical job in Irvine?
Under Section 5-9-205(A), permits are required for installations described in the adopted codes unless the building official grants a written exemption for proper cause. Routine repairs like swapping a fixture without altering wiring may qualify for an exemption, but new circuits, panel changes, and most wiring work need a permit.
Can I run new outdoor wiring overhead on my Irvine property?
No. Section 5-9-403(A) amends the Electrical Code to require that all outside wiring on private property be installed underground, with an exception only for temporary construction wiring permitted under Section 590 while a project is under active construction.
