Swimming Pools & Spas in Kauai County, HI (2026)

Fencing Requirements

Kauai County enforces residential swimming pool barrier requirements through Kauai County Code Chapter 12 (Building Code), which adopts the Hawaii State Building Code (based on the 2018 IBC) and the Hawaii State Residential Code (based on the 2018 IRC). Pools, spas, and hot tubs holding water more than 24 inches deep require a barrier at least 48 inches high with no openings that pass a 4-inch sphere, and gates that open outward, self-close, and self-latch. Public and semi-public pools (hotels, condos, resorts) are separately regulated by the Hawaii Department of Health under HRS Chapter 321 and HAR Chapter 11-10, which require a continuous fence at least 4 feet high. Pool building permits are reviewed and inspected by the Kauai County Department of Public Works, Building Division.
