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.
Kailua FAQ
Is a permit needed for a standard wooden fence in Kailua?
Wooden fences 6 feet or shorter in residential yards are often exempt, but check ROH 18-3.1 and any SMA overlays before building.
What happens if I skip the permit?
You risk a stop-work order, after-the-fact permit fees at multiple times normal cost, and forced removal if the structure violates code.
