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

Orange County Codified Ordinances Sec. 7-2-9 (Section 90-16, Permits) bars installing electrical equipment or performing electrical work, or altering or adding to existing equipment, within or on any building, structure or premises, publicly or privately owned, in the unincorporated area of Orange County, without first securing a permit from the Building Official. The Board of Supervisors adopted the 2023 National Electrical Code and 2025 California Electrical Code as the underlying technical standard under Sec. 7-2-1, and OC Public Works enforces it, with the Building Official empowered to interpret the code, issue stop-work orders, and disconnect utilities in an emergency under Sec.

7-2-7. Sixteen classes of work are exempt from the permit requirement under Sec. 7-2-9(a), including minor repairs such as replacing lamps or plugging portable equipment into existing receptacles, like-for-like repair or replacement of fixed motors, transformers or appliances, temporary decorative lighting, reinstallation of attachment-plug receptacles, and taping joints. Everything else needs a written application to OC Public Works describing the work, with load calculations, specifications and schedules submitted for plan review before a permit issues. Commercial and industrial owners doing recurring work can apply for an annual permit instead of one per job, reporting completed work to OC Public Works within fifteen days of each month's end under Sec.

7-2-9(d). A permit expires if authorized work is not started within twelve months of issuance, or if it is suspended or abandoned for 180 days; work can resume only after the permit is extended or reissued under Sec. 7-2-9(e). Under Sec. 7-2-10(f), starting electrical work before a permit is issued and paid for is itself a violation, and the Building Official assesses double the normal fee on top of any other penalty; fees themselves, including plan-check and investigation fees, are set by the Board of Supervisors.
