East Honolulu FAQ
Do I need a permit for a Hawaii Kai fence?
Usually yes. ROH 18-3.1 only exempts retaining or riprap walls up to 30 inches. Taller walls, masonry fences, and pool barriers require a Honolulu DPP permit before construction starts.
Are hillside walls reviewed more strictly?
Yes. Kuliouou and Hawaii Loa hillside lots often need engineered drawings and drainage analysis for retaining walls above 30 inches, on top of the standard 18-3.1 building permit process.
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.
