Honolulu FAQ
Does my hot tub need a fence if I have a lockable cover?
A rigid, ASTM F1346-compliant safety cover that latches closed often satisfies the barrier rule in Section 16-6.2 for a private residential spa. Confirm with DPP during permitting.
Do I need a permit for a plug-in spa?
Yes, if it is a permanent installation or hardwired. Plumbing and electrical permits are typically required under Chapter 18 even for many 120-volt plug-in models.
Waipahu FAQ
Can we share a spa across multi-generational ohana units?
Yes if installed on a permitted pad with required bonding and barriers or cover. Section 16-6.2 protects children across the household.
Does a swim spa count as a pool or a spa?
