Temecula, CA Swimming Pools & Spas: Hot Tub Rules (2026)

Hot tubs and spas in Temecula are subject to many of the same rules as swimming pools. Portable, factory-built spas with locking covers may not require a building permit for the unit itself, but always require an electrical permit for the 240V GFCI-protected circuit (typically a 50-amp dedicated circuit on a manual disconnect within sight of and at least 5 feet from the spa per NEC Article 680). Built-in/in-ground spas require a full building permit like a pool. Under California Health & Safety Code §115921(a)(8), a hot tub or spa with a locking safety cover meeting ASTM F1346 is exempt from the broader pool barrier requirements; if the cover is not lockable, two of the seven Pool Safety Act features apply. Setbacks from property lines typically 3-5 feet; setbacks from windows/doors often required by code. Electrical bonding requires equipotential bonding of all metal within 5 feet, ground/neutral bar separation, and GFCI on the disconnect. Spa drainage to landscaping is allowed if dechlorinated; no spa water should drain to street/storm drain. Pump and blower noise must stay within TMC §9.20 limits (50 dBA daytime, 45 dBA nighttime at the property line) — schedule filtration cycles outside quiet hours. HOAs may impose additional architectural rules on placement and screening.
