Swimming pool permit rules in Honolulu County, HI — also covering above-ground pools, in-ground pools, and spa installations — set fencing, barrier, alarm, and inspection requirements.
Any residential swimming pool construction, installation, or substantial modification on Oahu requires a building permit from the Department of Planning and Permitting, with fees set under Chapter 18.
ROH Chapter 18 establishes the permit-fee framework for building, electrical, plumbing, and sidewalk work, which includes swimming pools. Construction is further governed by Article 16-6 (Residential Swimming Pools) and the Hawaii State Residential Code adopted at ROH 16-1.2. Applicants submit plans to the Department of Planning and Permitting (DPP) covering structural, electrical bonding, and plumbing systems. Permits are required for in-ground and above-ground pools that exceed statutory depth or capacity thresholds, as well as for barrier, deck, and equipment installations. Inspections are required before final approval.
Building without a permit may trigger stop-work orders, permit-after-the-fact fees, daily civil fines under Chapter 16, and required corrective work to meet code.
