Murrieta, CA Building Safety: Building Permits (2026)

030 sets the scope of Title 15: it applies to the construction, alteration, moving, demolition, repair and use of any building or structure and the installation, alteration, repair or replacement of electrical, plumbing and mechanical systems within the city, unless specifically exempted, and it excludes structures and equipment preempted by state law, such as public utility towers and poles. 52, though retaining walls tied to grading still need a Title 15 permit. 130 requires any owner or authorized agent who intends to construct, enlarge, alter, repair, move, demolish or change the occupancy of a building, or to erect, install, alter, repair, remove, convert or replace a regulated electrical, gas, mechanical or plumbing system, to first apply to the building official and obtain the permit; projects of one acre or more also trigger a requirement to obtain the state's NPDES Construction Stormwater Permit, proof of which the city can demand at any time.

140, a permit expires and becomes void if the authorized work is not commenced within one year of issuance, or if it is suspended or abandoned for 180 days, with no recorded inspection approval counting as no progress. The building official may grant a one-year extension for good cause, and subsequent extensions or renewals beyond that first year are granted solely at the building official's discretion, with renewal fees set by the city council based on project scope and remaining plan-review and inspection work. 040, and a permit paid for with a dishonored check is automatically revoked.
