Fontana FAQ
Does a hot tub need a fence around it in Fontana?
Not if it has a locking safety cover meeting ASTM F 1346 standards. Otherwise pool fence rules apply.

You can install it but electrical and plumbing permits plus inspection are required for safe, legal operation.
Hesperia FAQ
Does a plug-in portable spa need a permit?
A cord-and-plug 120V portable spa generally does not require a building or electrical permit, but if it holds water more than 18 inches deep it is a 'swimming pool' under HSC §115921(a) and the SB 442 two-feature safety requirement applies.
Is a locking spa cover enough by itself?
An ASTM F1346 compliant safety cover counts as one of the two required SB 442 features (HSC §115922(a)(3)). A second feature — such as exit door alarms or a self-latching door — is still required.
