Summary

City-specific rules exist: Las Vegas, North Las Vegas, and Henderson have their own plumbing permits rules that differ from Clark County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

Any owner or authorized agent who intends to perform grading or construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building, structure, pool, spa, sign or ATS, or to erect, install, enlarge, alter, repair, remove, convert or replace any electrical, gas, mechanical or plumbing system, the installation of which is regulated by this code, or to cause any such work to be done, shall first make application to the building official and obtain the required permit(s).

Exception: This section does not apply to buildings, structures, or service equipment and installations directly used in utility generation or distribution which are installed on properly recorded easements belonging to water, gas, power, telephone, or other utility companies which are pre-emptively regulated and governed by the Nevada Public Utilities Commission, State of Nevada charter, or other public franchise, including, but not limited to, the Las Vegas Valley Water District, Southern Nevada Water Authority, Clark County Water Reclamation District, NV Energy and Southwest Gas. This exception does not apply to site preparation, block walls, fences, or habitable public areas, such as offices, meeting rooms, and service counters.

Full Breakdown

Under Clark County Code § 22.02.165, any owner or contractor who intends to install, alter, repair, remove, or replace a plumbing system must first apply to the building official and obtain a permit before starting work. The county's Plumbing Code, adopted at § 25.08.010, is the 2024 Uniform Plumbing Code as amended by the Southern Nevada Amendments. Minor fixes -- clearing a stoppage or swapping a fixture in place without touching concealed piping -- are exempt under § 22.02.195. This applies only in unincorporated Clark County, including the Las Vegas Strip resorts in Paradise and Winchester; Las Vegas, Henderson, North Las Vegas, Boulder City, and Mesquite enforce their own codes.

Violations & Fines

Working without a required permit is a misdemeanor punishable by up to $1,000 and six months in jail per day of violation, plus a work-without-permit fee up to $4,000 for residential or $50,000 for other construction.

The 2024 Uniform Plumbing Code as amended by the Southern Nevada Amendments, adopted as the Plumbing Code of Clark County under § 25.08.010.
