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.
San Bernardino FAQ
Do I need to fence a hot tub in San Bernardino?
Not if you install a rigid locking safety cover meeting ASTM F1346 and keep it locked when the spa is not in use. The cover substitutes for the perimeter barrier and satisfies the state secondary safety feature requirement.
Does my spa need a dedicated electrical circuit?
Yes. California Electrical Code requires a dedicated 240-volt GFCI-protected circuit with a disconnect between 5 and 50 feet from the spa. A licensed electrician should handle the install and pass inspection.
