Summary
In unincorporated Orange County, building work needs a permit and paid fee before starting; skipping straight to construction doubles your permit fees under County Code Section 109.2.
Failure to pay fees and obtain a permit before commencing work shall be deemed a violation of this Code, except when it can be proven to the satisfaction of the Building Official that an emergency existed which made it impractical to first obtain the permit. A violation shall result in an assessment of double fees for work done prior to permit issuance.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 157).
Full Breakdown
Before any building, electrical, plumbing, or mechanical work begins in unincorporated Orange County, the applicant must file a permit application with OC Public Works describing the work, the property, and its valuation, then pay the fee set by the Board of Supervisors. Section 109.2 makes starting work before permit issuance a Code violation unless an emergency made getting the permit impractical first, and the Building Official then charges double the normal permit fee for work already done without one. Continuing without ever obtaining the permit can also be prosecuted as a misdemeanor under Section 114.1, with fines up to $500 and up to six months in jail for each day the violation continues.
Violations & Fines
Unpermitted work draws double fees under Section 109.2 and can be charged as a misdemeanor under Section 114.1: up to $500 and six months in jail per day.
