East Honolulu's Fence Regulations: The Rules That Matter
Every city handles fence regulations a little differently. In East Honolulu, Hawaii, there are 6 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.
Permit Requirements
The City and County of Honolulu Department of Planning and Permitting requires a building permit for any fence greater than 6 feet in height and any wall greater than 30 inches in height, under ROH Chapter 18. Fences at or below 6 feet and walls at or below 30 inches are exempt from the building permit requirement.
Key details: Code Section: ROH Chapter 18 (Building Code). Permit required - fences: Greater than 6 feet. Permit required - walls: Greater than 30 inches. Exempt: Fences <= 6 ft; walls <= 30 in. Permitting agency: Honolulu Dept. of Planning and Permitting (DPP).
Building a fence over six feet or a wall over 30 inches without a permit is a violation of ROH Chapter 18, subject to stop-work orders, civil fines, and after-the-fact permit penalties. Work done without a permit may have to be removed or brought into compliance at the owner's expense.
Neighbor Fence Rules
East Honolulu neighbor fence disputes fall under ROH 21-4.30 yard setbacks combined with 21-4.60 height limits, since Hawaii has no dedicated spite fence statute for Hawaii Kai or Aina Haina lots.
Key details: Primary section: ROH 21-4.30. Height companion: ROH 21-4.60. Spite fence law: None. Marina shared walls: Check easements.
Encroachment onto a neighboring East Honolulu parcel triggers LUO enforcement actions, mandatory fence relocation, civil fines, and potential private civil suits for trespass or nuisance.
Pool Barriers
East Honolulu pool owners in Hawaii Kai, Portlock, and Aina Haina must install code-compliant barriers under ROH Sec. 16-6.2, with public pools in the CDP subject to companion rules at 16-7.9.
Key details: Code section: ROH 16-6.2. Minimum height: 4 feet. Gate requirement: Self-closing, self-latching. Opening spacing: Under 4 inches.
Non-compliant pool barriers can prompt immediate DPP orders to drain the pool, daily civil fines, and potential personal liability following any drowning incident.
This is not one of those rules that cities tend to ignore. East Honolulu actively enforces its pool barriers requirements.
Material Restrictions
The Honolulu Land Use Ordinance does not restrict materials for ordinary residential fences, but where a solid wall or fence is required as a buffer between commercial/industrial and residential uses, chain link is expressly excluded. In certain special districts and the apartment precinct, dwelling fences must use open material such as wrought iron or lattice, not chain link.
Key details: Code Section: ROH Sec. 21-4.70-1(d); Sec. 21-5.70-2/-7/-9/-10. Ordinary residential fence material: Not generally restricted. Required buffer fences: Chain link excluded. Apartment precinct dwelling fences: Open material (wrought iron/lattice), not chain link.
Installing a prohibited material where a non-chain-link buffer wall or fence is required, or a non-conforming dwelling fence material in a regulated precinct, is enforced by DPP through notices of violation, civil fines, and orders to replace the fence with conforming material.
Height Limits
In East Honolulu, which is governed by the City and County of Honolulu Land Use Ordinance, walls and fences (other than retaining walls) up to 6 feet may enclose or project into any required yard. Public-utility fences may reach 8 feet (9 feet with security wire), and fences on agriculturally dedicated land may reach 10 feet.
Key details: Code Section: ROH Sec. 21-4.30(c). Standard max (any required yard): 6 feet. Front yard (business/industrial districts): Fences prohibited in required front yard. Public utility fences: 8 ft (9 ft with security wire). Agricultural-dedicated land: Up to 10 feet.
Fence and wall height violations are enforced by the City and County of Honolulu Department of Planning and Permitting (DPP). A structure exceeding the six-foot limit can trigger a notice of violation, a civil fine, and an order to lower or remove the structure. Building a fence over six feet (or a wall over 30 inches) without the required building permit is a separate violation under ROH Chapter 18.
Retaining Walls
In East Honolulu, retaining walls containing fill within a required yard may not exceed six feet, measured from the lower of existing or finish grade to the top of the wall. Walls protecting a cut have no height limit, and safety railings or fences on top of a retaining wall are limited so the combined height stays within prescribed limits.
Key details: Code Section: ROH Sec. 21-4.40. Max fill retaining wall (required yard): 6 feet. Wall protecting a cut: No height limit (6 ft if also holds fill). Safety railing of different material: <= 6 ft above the wall. Permit threshold: Walls over 30 inches (ROH Ch. 18).
Retaining walls that exceed the six-foot fill limit in a required yard, or combined wall-plus-fence assemblies over the allowed height, are enforced by DPP and may require redesign, lowering, or removal, plus after-the-fact permit penalties for walls over 30 inches built without a permit.
The Bottom Line
East Honolulu's fence regulations rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming East Honolulu is broadly strict or permissive.
Keep in mind that East Honolulu can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
