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.
Rancho Cucamonga FAQ
Can I just plug in a spa and skip the permit?
No. Even cord-connected spas that plug into a 120 volt outlet require permits if they hold water deeper than 18 inches, and most hot tubs need a dedicated 240 volt circuit.
Do I need a fence around my backyard hot tub?
Not if you install a locking rigid cover meeting ASTM F1346 and keep it secured when unattended. Otherwise the standard pool barrier rules apply.
