Yucaipa, CA Building Safety: Electrical Permits (2026)

Section 15.04.030 adopts the California Electrical Code, 2025 Edition (Part 3, Title 24, California Code of Regulations), including all annexes, as the electrical code of the City of Yucaipa. It incorporates and amends the National Electrical Code, 2023 Edition, published by the National Fire Protection Association, and it covers design, construction, installation, alteration, repair, relocation and use of electrical systems along with permits and fees. A copy sits in the Building Division of the Development Services Department for public inspection.

Three local amendments change the base code. Article 310.3(B).1 requires copper wire for wiring No. 6 and smaller in all installations, and the Building Official can consider aluminum wiring for feeder lines only, on an individual basis where adequate safety measures can be ensured. Article 310.121 requires continuous inspection of any aluminum conductors of No. 6 or smaller used for branch circuits, performed by an independent testing agency approved by the Building Official, to check the torque of connections at their termination points. Article 690.13(A)(1) requires the PV disconnecting means at a readily accessible location on the outside of the building, nearest to the point of entrance of the system conductors and within 3 feet of the main electrical service meter, with an additional disconnect at the remote location when part of a PV system sits on a detached structure.

Permit administration comes from the city's amendments to the California Building Code in § 15.04.015. Section 109.2 sends electrical permit fees to the most recent City Council resolution, with the plan review fee due when plans are submitted. A residential permit becomes invalid unless work starts within 365 days of issuance, and a commercial permit unless it starts within 180 days. Section 109.8 allows a re-inspection fee when work called for inspection is not complete or corrections are not made, though not the first time a job is rejected. The City Council is the board of appeals under Section 113.3.
