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.
Rialto FAQ
Do I need a fence around my locking hot tub in Rialto?
Not if the spa has an ASTM F1346 locking safety cover. The cover satisfies the CBC §3109 barrier requirement for portable spas.
Can I plug a portable spa into a regular outlet?
Only if it's a 120V cord-and-plug spa under 50 amps with a built-in GFCI. Larger spas need a hard-wired dedicated circuit with permit and inspection.
