Honolulu's Land Use Ordinance Section 21-4.30 defines required yards and street setbacks, including what fences and structures may occupy property lines shared with neighbors across Oahu.
ROH/LUO 21-4.30 is the island-wide yard and street-setback rule. It specifies minimum front, side, and rear yard depths by zoning district and identifies which fences, walls, eaves, and accessory structures may project into required yards. Hawaii has no dedicated ROH 'spite fence' statute; instead, neighbor-line fence disputes are resolved under the height and yard provisions of 21-4.30 together with 21-4.60. Common rules allow fences on the property line up to district height maximums, prohibit encroachment across the line, and require any shared wall to be supported equally. Easements and shoreline setbacks add further limits near the ocean or drainage channels.
Setback violations under LUO Article 2 enforcement can result in mandatory relocation, daily civil penalties, and recordation of notices of violation against the title that may impede sale or refinancing.
