Full Breakdown
Under ROH Article 6, a residential pool cannot get a building permit until the owner provides a fence, wall, or other enclosure, or in the alternative a pool cover or similar protective device. The specific barrier standards are set by Sections 3109.4 and 3109.5 of the International Building Code, as amended, which the ordinance incorporates rather than restating. The building official may modify height, design, or gate requirements for good cause, or substitute other protective devices offering equal protection. Hotel pools are exempt. Public pools instead fall under the State Department of Health's rules at Hawaii Administrative Rules, Title 11, Chapter 10, covering construction, illumination, and operation.
Violations & Fines
Building or operating a pool without the required permit and barrier violates ROH Chapter 16 Article 10 penalty provisions; the department of planning and permitting can withhold or revoke the permit.
