Kapolei propane storage must meet NFPA 58 through Honolulu Chapter 20, with larger aggregate capacities triggering HFD plan submittal and vehicle barrier protections.
ROH Chapter 20 adopts NFPA 1 Chapter 69, which incorporates NFPA 58, the LP-Gas Code. Typical Kapolei residential installations such as 20-pound grill cylinders and small whole-house tanks are allowed with proper installation. Any container or aggregated set of containers with a water capacity of 125 gallons or more requires HFD permit and plan submittal. Vehicular barrier protection is required within 10 feet of public vehicular ways, a rule relevant to commercial propane exchange cages at Kapolei retail centers. Restaurants and industrial users at Kapolei Enterprise Center must also meet separation-distance and ventilation rules.
Non-compliant storage can draw HFD red tags, delay business occupancy, and increase insurance exposure after a release.
