Full Breakdown
Riverside County adopted the 2025 California Electrical Code in its entirety at Riverside County Code Section 15.04.160, and its amended Building Code permit-exemption list at Section 15.04.050 lists only specific electrical work that skips a permit: minor repairs like lamp replacement or plugging equipment into existing receptacles, temporary testing setups, and radio or television transmission equipment other than its power-supply wiring, towers, and antennas. Everything else, including new circuits, panel upgrades, and wiring for additions, needs a permit from Building and Safety before work starts, with fees set by Ordinance No. 671 and Appendix A. This applies only in the unincorporated area; Riverside, Temecula, Palm Springs, and the county's other cities enforce their own electrical permit rules.
Violations & Fines
Doing permit-required electrical work without one is Construction Without Permit under Section 105.1.3; the owner must obtain the permit and the building official may require testing to verify code compliance.
