Full Breakdown

6 gauge or smaller used for branch circuits receive continuous inspection by an independent testing agency approved by the Building Official to confirm proper torque at their termination points. Both provisions were adopted by Ordinance 2629 on November 12, 2025. Because the Electrical Code is folded into Title 15's Building Code family rather than issued as a standalone rule, electrical work in Westminster is permitted and inspected through the same Building Division process as other construction trades, and any wiring project must be reviewed against the 2025 California Electrical Code as amended before the Building Official signs off.

Violations & Fines

Electrical work performed without a permit, or that fails to meet the 2025 California Electrical Code as adopted and amended by Sections 15.12.010 and 15.12.020, does not pass Building Official inspection and cannot receive final sign-off or a certificate of occupancy. Unapproved aluminum branch-circuit wiring lacking the required continuous independent-agency inspection under Section 110.5.1 is a specific, locally-added violation the Building Official checks for separately from the base state code.
