Summary
Hawaii County zoning lets a shared boundary fence up to six feet sit on the line without setback. The County sets no cost-sharing or spite-fence rule; boundary disputes are civil matters handled between owners under Hawaii state law.
No fence, wall, architectural feature, or other obstruction shall be placed or be without gates or openings so as to prohibit complete access around any main building at all times.
Full Breakdown
Chapter 25 treats a perimeter boundary fence or wall up to six feet as permitted on the property line with no yard requirement (25-4-43(a)), so a shared fence is typical. The County does not require a neighbor's consent, mandate cost-sharing, or regulate "spite fences." Those are private civil matters under Hawaii common law, resolved between owners or in court. The Zoning Code does require that a fence not block complete access around a main building (25-4-43(b)) and enforces the three-foot corner sight-triangle (25-4-42(b)) for traffic safety near shared street corners.
Violations & Fines
The County enforces zoning/sight-triangle rules, not private boundary disputes; owners resolve cost-sharing or encroachment claims civilly.
