Plumbing permits and septic in Clark County, Nevada
Updated · Editorial team; not yet technically reviewed
Short answer
In unincorporated Clark County, Building & Fire Prevention doesn't require a permit to stop leaks in drain, waste or vent pipes or to clear stoppages, including pulling and resetting a toilet. Replacing a defective trap or pipe with new material counts as new work and needs a permit. Septic systems county-wide are permitted by the Southern Nevada Health District.
What Clark County handles

Cities have their own departments
Las Vegas, Henderson and North Las Vegas run their own building departments; the county rules above apply to unincorporated areas. See the Las Vegas city page for local conditions like very hard water.
Septic on the edges of the valley
Septic is mostly found in rural and outlying areas. SNHD also certifies septic and well systems for real estate transactions, so buyers of an outlying property should ask for that record. For drain trouble, see drain cleaning.
