Hot tubs and spas in unincorporated LA County require building permits for permanent installations from LA County Building & Safety. GFCI protection mandatory. Safety covers required when not in use. May require barrier depending on design and accessibility.
Hot tubs and spas in unincorporated LA County require building permits for permanent installation (in-ground or built-in). Portable plug-in hot tubs under standard household electrical circuits may be exempt from building permits but still require safety barriers. All spas must comply with the Swimming Pool Safety Act barrier requirements regardless of whether a building permit is needed. A hard safety cover meeting ASTM F1346 can serve as the barrier for spas. Electrical connections for 240V spa circuits require a separate electrical permit and inspection. Spa water must not be discharged to storm drains.
Installing a permanent hot tub without a building permit carries standard building code violations with double retroactive fees. Inadequate safety barriers carry fines of $250-$1,000 per day. Improper electrical connections (especially the required GFCI protection and bonding) create electrocution hazards with serious code violations. Draining spa water to storm drains violates environmental regulations.
