Honolulu County
Honolulu treats above-ground pools the same as in-ground pools for safety. Under ROH Chapter 16, which adopts the Hawaii State Residential Code (IRC) and Hawaii Building Code Section 3109, any residential pool capable of holding more than 24 inches of water must be enclosed by a 48-inch barrier, with openings that block a 4-inch sphere, self-closing/self-latching gates, and only a 4-inch maximum gap between the pool wall and the barrier when the pool wall itself is used as the enclosure. Ladders or steps must be removable, lockable, or independently fenced. A building permit from DPP is required before installation of any pool deeper than 24 inches.

East Honolulu FAQ
Does a small inflatable kiddie pool need a permit?
Temporary inflatable pools below the state code depth threshold are generally not regulated, but anything exceeding the threshold triggers barrier and permit rules.
Can I use the pool's own wall as the required fence?
Yes, if the wall is non-climbable, meets the minimum height on all sides including the downhill grade, and the ladder is removable or securely locked when unattended.
Honolulu FAQ
Do I need a permit to install an above-ground pool on Oahu?
Yes. Under ROH Chapter 16, any pool capable of holding water more than 24 inches deep, including above-ground models, requires a Department of Planning and Permitting (DPP) building permit before installation. The permit submittal includes a site plan, the manufacturer's data sheet, and a barrier plan, and DPP performs a final inspection before the pool may be filled.
Can the pool's own wall act as the safety barrier?
Yes, if the outer wall of the above-ground pool is at least 48 inches above the surrounding grade. Under Hawaii Building Code §3109.4 (adopted by ROH Chapter 16), when the pool wall serves as the barrier, the vertical gap between the top of the pool wall and the bottom of any deck-mounted barrier cannot exceed 4 inches, and openings in the pool wall cannot pass a 4-inch-diameter sphere.
What do I have to do with the ladder when the pool is not in use?
If the above-ground pool's wall is the barrier, the ladder or steps must either be capable of being secured, locked, or removed when the pool is not in use, or must be surrounded by a separate code-compliant 48-inch fence. When the ladder is removed or secured, any opening it leaves cannot allow a 4-inch sphere to pass through.
Are above-ground pool rules different for short-term rental properties?
The barrier standards under ROH Chapter 16 apply identically, but rental and shared pools also fall under Hawaii Department of Health rules in HAR Title 11, Chapter 10 (Public Swimming Pools). STR registrations under Ordinance 22-7 require all pools on the property to be code-compliant, and a non-compliant barrier can lead to suspension of the STR registration certificate.
