Most renovation work in unincorporated Orange County requires building permits. Structural, electrical, plumbing, mechanical, and roofing work all need permits. Cosmetic work does not. Apply through OC Development Services.
Under Orange County's adopted building code, permits are required for: structural alterations, electrical work, plumbing modifications, HVAC, roofing, window/door replacements changing openings, and additions. Cosmetic work (painting, flooring, replacing fixtures in kind) is exempt. Kitchen and bathroom remodels typically require permits for electrical and plumbing. The process involves plan submittal, review, permit issuance, inspections, and final sign-off. OC Development Services offers online applications through their ePermit system. Energy upgrades (solar, EV charging) qualify for expedited review under California law. Licensed contractors are required for electrical and plumbing work.
Unpermitted work: stop-work orders, double fees, required opening of walls for inspection. Can complicate property sales and insurance.
