Ewa Gentry FAQ
Do I still need a fence if my hot tub has a locked cover?
A listed ASTM F1346 locked safety cover generally substitutes for a fence around a residential spa, but the cover must be in place whenever the spa is unattended.
Can I plug my spa into a regular outdoor outlet?
No. Most permanent spas require a dedicated 240V GFCI-protected circuit installed under permit; 120V plug-in models have their own listing requirements.
Urban Honolulu FAQ
Can I put a plug-in hot tub on my condo lanai?
Check your condo declaration first. Even if allowed, a fixed spa deeper than 24 inches will trigger Section 16-6.2 barrier rules and require a permit under Chapter 18.
Does a rooftop pool count as a spa or a pool?
It depends on depth and volume. Rooftop plunge pools deeper than 24 inches and above capacity thresholds are treated as pools under Article 16-6, with additional structural permit review.
