Honolulu's Land Use Ordinance (ROH Chapter 21) limits fences and walls to 6 feet in required yards. Fences taller than 6 feet or new fences costing over $1,000 require a building permit; shared boundary-line fences involve mutual consent and state cost-sharing law.
Under ROH Chapter 21, §21-4.30, walls and fences up to 6 feet may be placed in any required yard; front-yard fences in business and industrial districts are prohibited. Public utility fences may reach 8 feet plus security wire to 9 feet. Agricultural fences may reach 10 feet. Building permits are required for fences over 6 feet or any new fence installation exceeding $1,000 in cost. Fences must also comply with ROH Chapter 16 Building Code. For boundary-line fences, written neighbor permission is required when a fence is placed on the shared property line. Hawaii state law (HRS Chapter 664) governs shared fence cost disputes; courts equitably apportion construction and maintenance costs between adjacent owners.
Unpermitted fences over 6 feet or over $1,000 cost may result in stop-work orders and civil fines under ROH Chapter 16; removal or correction may be ordered by DPP.
