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.
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?
