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.
