ROH Sec. 21-4.60 caps building heights and defines building envelope planes for Kailua structures. Residential districts typically allow 25 to 30 feet, protecting windward viewsheds and ocean breezes.
Honolulu's Land Use Ordinance sets maximum structure heights at ROH 21-4.60, with cross-references in 21-3.70-1 for residential districts. Most Kailua R-5 and R-7.5 zones permit 25-foot flat-roof heights, extending to 30 feet for pitched roofs under envelope-plane provisions that slope inward from side property lines. Heights are measured from existing grade to the highest roof point. Lanikai, Kalama, and other beach-adjacent neighborhoods may face additional view-corridor protections. Rooftop equipment, chimneys, and solar structures have limited envelope exceptions. Historic or special district overlays may reduce allowable heights further.
Exceeding height limits can force roof modification or demolition, void certificates of occupancy, and create lender and insurance complications.
