Clark County, NV Swimming Pools & Spas: Hot Tub Rules (2026)

Clark County Title 22 and Title 30 regulate hot tubs and spas through the Department of Building and Fire Prevention. A building and electrical permit is required for any spa, hot tub, or whirlpool deeper than 24 inches or any spa with a capacity over 120 gallons regardless of depth. Plumbing permit is not required for self-contained portable spas that simply plug in, but the dedicated electrical circuit (typically 240V, 50A, GFCI-protected) must be inspected. Setbacks under Title 30 typically require 5 feet from side and rear property lines. Spas must meet the same barrier requirements as swimming pools under NRS 444.065 and IRC Appendix G unless the spa has a listed safety cover meeting ASTM F1346 (rigid, locking, capable of supporting a 50 pound load without opening) which satisfies the barrier requirement for residential spas. Federal VGBA applies to all suction outlets, so only UL-listed VGB-compliant drain covers may be used; older spas with single drains must be updated when modified or when covers are replaced. Electrical bonding of the spa shell, metal railings, metal decking, and nearby plumbing is required under NEC 680. Hot tubs located on decks or rooftops may require structural review for weight loading (roughly 100 pounds per square foot when full). Indoor spas have additional ventilation and humidity code requirements.
