Chino FAQ
I bought a plug-in 110V portable spa — do I still need a permit?
Most 110V plug-in spas under 200 gallons may not require an electrical permit if they use a listed cord-and-plug GFCI assembly, but a building permit and SB 442 cover are still required because water depth exceeds 18 inches (HSC §115921 and §115922).
Is an ASTM F1346 safety cover alone enough to satisfy SB 442?
No. SB 442 requires at least two features (HSC §115922). The cover counts as one — pair it with an enclosure, exit alarm, self-closing door device, or water-entry alarm.
Fontana FAQ

Not if it has a locking safety cover meeting ASTM F 1346 standards. Otherwise pool fence rules apply.
