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.
Pearl City FAQ
Do I need a permit for a Pearl City 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 construction begins.
Do renters near Pearl Harbor pull their own permits?
Typically no. Military-family renters should secure landlord approval, and the permit is usually pulled by the owner or licensed contractor. The permit still runs against the property, not the occupant.
