Hot tubs and spas in Kailua are regulated under the Residential Swimming Pools article of ROH, with barrier and plumbing requirements applying when depth or capacity thresholds are met.
There is no dedicated hot tub or spa chapter in the Revised Ordinances of Honolulu. Instead, these fixtures are regulated under ROH Chapter 16, Article 6 in conjunction with the Hawaii State Residential Code adopted by ROH Sec. 16-1.2 and the plumbing code. Where a hot tub meets the statutory depth or water capacity threshold, the fencing and barrier rules in ROH 16-6.2 apply. Safety covers meeting ASTM standards may satisfy barrier requirements in many residential configurations, which is how most Kailua backyard spas are compliant. Electrical bonding and GFCI protection are required.
Non-compliant spas may face citations for missing barriers or uncertified electrical work, along with required corrective work before reuse.
