Honolulu's LUO Section 21-4.60 defines 'fence' and governs allowed materials including wrought iron, wire, wood, vinyl, and plastic supported by post foundations across all Oahu zoning districts.
The Land Use Ordinance defines a fence at ROH 21-4.60 as a barrier of wrought iron, wire, wood, vinyl, plastic, or similar material supported by post foundations that serves to enclose or screen a lot. The same section controls both height and permitted materials; there is no separate ROH section devoted solely to fence materials. Masonry walls over a certain height are treated as walls rather than fences and fall under structural building code provisions in Chapter 16. Barbed wire, razor wire, and electrified fences are restricted in most residential zones and require special approval in industrial and agricultural districts. Materials must also satisfy the building code's wind-load requirements for Oahu's hurricane zone.
Using prohibited materials triggers LUO enforcement: notice of violation, removal or replacement orders, daily fines, and, for electrified fences in residential zones, potential nuisance abatement action.
