Full Breakdown
040 layers city-specific amendments on top of it. 4 puts the permit-pulling duty for commercial jobs squarely on a licensed electrical contractor rather than a property owner or general contractor. The city also tightened several technical rules: conductor material defaults to copper, aluminum or copper-clad aluminum, and no aluminum conductor smaller than #6 AWG is allowed anywhere in the city regardless of what the base NEC would otherwise permit. Non-metallic sheathed cable (Romex, Type NM/NMC/NMS) is permitted in one- and two-family dwellings and in Type III, IV and V multifamily construction, but it is barred outright from commercial applications even inside a mixed-use building.
Accessory structures or signs on the same lot must run their connecting conductors underground except in agricultural areas, and any panel with spare circuit breaker positions must have raceways stubbed to an accessible location for future circuits. 4(A), covered separately from this general electrical permit framework. Plans for panels with open breaker space, underground runs, and commercial permit applications are all reviewed by the Building and Safety Department before a permit issues.
Violations & Fines
Electrical code violations are prosecuted under the same enforcement chain as the rest of Title 15: Section 90.4 ties violations to the prohibitions in Section 15.02.060 and the penalties in Chapter 1.20. Chapter 15.04.070 makes each day a violation continues a separate offense, and Section 15.04.080 lets the city seek civil abatement, including an injunction, on top of any criminal penalty.
