Placer County, CA Building Safety: Electrical Permits (2026)

400 adopts the 2025 California Electrical Code (Title 24, Part 3 of the California Code of Regulations, based on the 2023 National Electrical Code), including its reference Annex C, as the code the building services division enforces on every electrical permit. 440 modify and supplement that adopted code. 1, the chief building official may withhold or disconnect electrical power from any building classified as dangerous under the Placer County Code or otherwise hazardous. 430 adds an elevation-specific clearance rule: above 3,500 feet, the main service panel must have covered protection while keeping a readily accessible path to it, unless all over-current devices besides the main disconnect sit inside in a readily accessible sub-panel.

1 so that temporary electrical service can be authorized only during active construction or repair under a valid permit, or where the conditions of approval specifically allow temporary service. Because the county sits partly above 3,500 feet in the Sierra foothills and Tahoe basin, the panel-clearance and temporary-power rules apply on top of the base NEC requirements enforced at lower elevations, and any electrical work still needs its own permit and inspection through the building services division even when it accompanies an otherwise exempt structure.
