Propane installations in Mililani Town follow ROH Chapter 20's adoption of NFPA 1 Ch. 69 and NFPA 58. HFD permits are required, and tanks or aggregated capacity of 125 gallons water capacity or more need plan review.
LP-gas storage and installations in Mililani Town are governed by ROH Chapter 20 through NFPA 1 Chapter 69 and NFPA 58. HFD permits are required under NFPA 1 Sec. 69.1.2 for new installations and meaningful modifications. Containers or aggregated containers of 125 gallons water capacity or more must be submitted for plan review, covering setback from structures, ventilation, and anchoring. Containers within 10 feet of a public vehicular way need impact protection (bollards). Multi-family developments and townhome clusters common in Mililani require particular attention to setback and separation, and many HOAs further regulate tank placement, screening, and aesthetics.
Unpermitted or unsafe installations can be red-tagged by HFD, cited under Chapter 20, and may jeopardize certificates of occupancy and HOA approvals.
