Honolulu FAQ
Can I build a 6-foot privacy fence along my property line without asking my neighbor?
If the fence is entirely on your property, no consent is needed, but you still need a building permit if it costs over $1,000. If placed exactly on the shared line, written neighbor permission is required.
Who pays when a shared boundary fence needs repair in Honolulu?
No Honolulu ordinance specifies a split; Hawaii HRS Chapter 664 governs disputes, and courts divide costs equitably. Neighbors should agree in writing on maintenance responsibilities before building.
Are there different fence height rules for front versus back yards?
The LUO 6-foot maximum applies to required yards overall. Front-yard fences in commercial and industrial districts are prohibited; residential front yards may have fences up to 6 feet with a permit.
Waipahu FAQ
Can I put a fence on the line in Waipahu?
Yes. ROH 21-4.30 permits fences on shared property lines up to the district height cap in 21-4.60. Fence and footings must remain fully on your side to avoid encroachment and neighbor disputes.
What about a neighbor's spite fence?
Honolulu has no spite fence statute. Remedies rely on ROH 21-4.30 and 21-4.60 height and setback rules, nuisance claims, and state trespass law. Start with a complaint to Honolulu DPP.
