Hot tubs and spas in Pearl City follow the residential pool article, with Section 16-6.2 barriers triggered above depth thresholds and ASTM-rated covers an acceptable substitute for spa fencing.
No separate hot tub chapter exists in the ROH. Spas fall under Chapter 16 Article 6 together with the adopted Hawaii State Residential Code and plumbing code. Section 16-6.2 barrier requirements apply when statutory depth or capacity is met, but a locked, rigid cover meeting ASTM F1346 may replace the barrier for spas, useful for Pearl City townhome lanais. Electrical bonding of the spa shell and equipment is mandatory under the adopted electrical code, and a Chapter 18 permit is required for hard-wired installations. Plug-and-play 120-volt units generally need only GFCI receptacle compliance, not a full plumbing permit.
Using a non-ASTM cover as barrier substitute, skipping electrical bonding, or omitting the installation permit for a hard-wired spa triggers Section 16-6.2 and Chapter 18 enforcement.
