Honolulu FAQ
Do I need a permit for a 6-foot wood fence in Honolulu?
Generally no, as long as it is not on a street corner or in a flood zone. Fences exceeding 6 feet require a building permit.
Are there extra rules for fences on corner lots?
Yes. Corner lots lose the 6-foot permit exemption, and fence height and placement are also subject to Land Use Ordinance visibility requirements.
Can I install barbed wire on my residential fence?
No. ROH Chapter 16 prohibits the use of barbed or razor wire for any fence in Honolulu.
Waipahu FAQ
Do I need a permit for a Waipahu fence?
Usually yes. ROH 18-3.1 exempts only retaining or riprap walls up to 30 inches. Taller walls, masonry fences, and pool enclosures require a Honolulu DPP building permit before work begins.
Can a tenant pull the fence permit?
Typically no. Building permits run against the property, so the landlord or licensed contractor must pull the permit. Tenants should secure written landlord consent before requesting fence changes.
