Unincorporated Riverside County

Riverside County requires a permit before constructing, enlarging, altering, repairing, moving, demolishing, or changing the occupancy of a building or structure, and before installing or altering regulated electrical, gas, mechanical, or plumbing systems. The county also requires final approval and, where applicable, a certificate of occupancy before use or occupancy.

Note: Riverside states exempt work still must comply with code and other laws, and the exemption does not authorize work performed in violation of county or state requirements.

Building code

Riverside County's building-codes page still lists the 2022 California codes, but the county separately published that the 2025 California Building Standards Code became effective January 1, 2026. As of March 21, 2026, the current code basis should be treated as the 2025 California Building Standards Code plus applicable Riverside County ordinances and Title 25 requirements. This is an inference from the county's later code-update notice because the general codes page appears stale.

Permit validity

The building permit application states the permit becomes null and void if no approved inspection is obtained for 180 days. The county allows one written 180-day extension if requested before expiration.

Owner-builder

Riverside's application requires an owner-builder declaration if the applicant is claiming exemption from contractor licensure. The form states owner-builders either perform work themselves or through their own employees, or contract exclusively with licensed contractors. The form also notes a civil penalty of up to $500 for a false exemption claim and states owner-builders bear the burden of proving work was not built for sale if sold within one year of completion.

Contractor requirements

The application form requires contractors to declare that they are licensed under California Business and Professions Code Chapter 9, beginning with Section 7000, and that the license is in full force and effect.

Scheduling deadline

Inspection requests are accepted each business day before 3:00 p.m., subject to available space. Inspections are normally performed the next business day under normal conditions. The county does not accept weekend or holiday inspections under the standard process and does not provide exact appointment times.

Typical sequence: Use the permit-specific inspection code list supplied with the permit, request each stage only when ready, keep the permit, site plan, approved stamped plans, and supporting documents on site, and obtain final inspection approval before occupancy or use.
