FENCE RULES – HARRISON (COUNTY), MISSISSIPPI

OVERVIEW

Residential fences are permitted on private property within Harrison County, subject to local regulations.

This page applies to properties in the unincorporated areas of Harrison County; incorporated municipalities such as Gulfport, Biloxi, D’Iberville, Ocean Springs and Long Beach may regulate fences under their own ordinances.

Fence-related requirements for Harrison County appear primarily in the Harrison County Unified Development Code as amended January 13, 2025, including Section 822 – Fencing and county drainage provisions; the Harrison County SmartCode v9 for SmartCode Special Use Districts; Harrison County Code Administration permit materials; and county floodplain and coastal-wetlands materials. Harrison County does not publish a separate standard residential fence-permit application in the referenced published materials.

This page focuses on typical single-family residential fencing. If the jurisdiction’s adopted code or ordinance materials do not state a specific limit or requirement, this page notes that the code does not specify one. If no local code or ordinance is available in the approved source packet, this page notes that the jurisdiction does not publish the relevant standard in the referenced published materials.

Compiled From Harrison County Unified Development Code as amended January 13, 2025, Harrison County SmartCode v9, Harrison County Office of Zoning, Harrison County Code Administration, 2018 International Building Code Section 105.2, Harrison County Building Permit Information Sheet, Harrison County Building Permit Application, Harrison County Development Permit Application and Instruction Sheet, Harrison County Flood Protection Information, Harrison County Drainage Management Site Plan Ordinance, Mississippi Department of Marine Resources wetlands-permitting materials, and Mississippi Damage Prevention Law / Mississippi 811 as of July 2026.

GOVERNANCE

The Harrison County Board of Supervisors governs county matters in unincorporated Harrison County. The Harrison County Office of Zoning administers and enforces the zoning portions of the Harrison County Unified Development Code, including Section 822 fence standards and the official zoning map.

The Harrison County Code Administration issues residential building permits and administers the county development-permit process for work in Special Flood Hazard Areas. The Harrison County Engineering Department and County Engineer administer applicable drainage-plan, roadway, and utility-review functions.

Harrison County identifies the 2018 International Building Code as an adopted county code. The referenced published materials do not identify the residential-code edition administered for ordinary one- and two-family work or state whether Harrison County is subject to, locally administers, or opted out of the Mississippi State Uniform Construction Code framework. The county construction-code posture is therefore Local Code Published but State Status Unclear for this page.

The Harrison County SmartCode v9 applies within the SmartCode Special Use District. Coastal-wetlands permitting is administered separately by the Mississippi Department of Marine Resources when proposed work affects regulated coastal wetlands or related areas.

PERMIT AND APPROVAL REQUIREMENTS

• Building-Code Permit Context: Harrison County identifies the 2018 International Building Code as an adopted county code. Section 105.2 includes a building-permit exemption for fences not over 7 feet high. Harrison County does not publish a separate affirmative building-permit trigger for fences over 7 feet or a separate standard residential fence-permit requirement in the referenced published materials.

• Zoning Compliance: Building-code permit exemptions and local construction-code administration are separate from zoning, setback, subdivision, floodplain, coastal-wetlands, stormwater, drainage, historic, right-of-way, easement, utility, and plat requirements. Confirm any applicable zoning conditions, setbacks, plat requirements, and site-specific limitations with the Harrison County Office of Zoning before construction.

• Floodplain Development Permit: A Harrison County development permit is required for any development in a Special Flood Hazard Area. The county application defines development to include fill, grading, excavation, drilling, buildings or other structures, and other man-made changes to real estate. Fence work involving those activities in a Special Flood Hazard Area is subject to review by Harrison County Code Administration before construction begins.

• Drainage Review: The County Engineer may require a Drainage Management Site Plan before grading or excavation that would fill, obstruct, or otherwise alter a creek, stormwater channel, or drainage facility. The code does not list ordinary fence installation as a separate Drainage Management Site Plan trigger.

• Coastal-Wetlands Review: The county development-permit instructions require Mississippi Department of Marine Resources approval paperwork and plans when that agency’s approval applies. Fence-related excavation, clearing, fill, access work, shoreline work, or placement affecting regulated coastal wetlands may require separate state review; this is not an ordinary permit requirement for established upland residential lots.

FENCE PLACEMENT RULES

• Property Lines: The ordinance does not state a setback requirement for standard residential fences from property lines; however, fences must be located entirely on the owner’s property and must not encroach into rights-of-way or easements.

• Front Yards and Streets: A privacy fence enclosing a front yard or placed adjacent to a street right-of-way may not exceed 4 feet. A fence adjacent to a street that is greater than 4 feet high must be placed at the building setback line.

• Corner-Lot Sight Triangle: On a corner lot where front and side yards are required, a wall, fence, sign, structure, or plant growth may not obstruct sight lines at elevations over 2 feet 6 inches above any portion of the crown of the adjacent roadways. The sight triangle is formed by measuring 25 feet from the intersection of the right-of-way lines and connecting those points.

• Drainage Easements: A public or private drainage easement may not be fenced or obstructed with material that obstructs the free flow of water, including the chain-link or rail examples stated in the code, when drainage is above ground.

• Maintenance Access: A fence along a drainage or utility easement must include a gate allowing ingress and egress for maintenance.

• Public Right-of-Way: Hedges may not be planted in a public right-of-way. Fence placement adjacent to a street remains subject to the 4-foot privacy-fence rule, the building-setback-line rule for taller street-adjacent fences, and the corner-lot visibility standard.

• SmartCode Special Use District: Where the Harrison County SmartCode v9 applies, private-frontage standards provide additional site-specific direction. The Porch & Fence frontage places a fence at the Frontage Line in the identified T3 through T5 settings, while the Common Yard frontage in the identified T2 through T4 settings remains unfenced.

• Utility Safety: Mississippi law requires notice through Mississippi 811 before excavation where the Mississippi Underground Utility Damage Prevention Act applies. For fence projects that involve digging, including digging, drilling, augering, boring, grading, or other movement of earth, notice generally must be given at least three full working days before excavation begins. Mississippi 811 is a notification center and does not mark lines itself; member utilities or their locators mark covered facilities, and the excavator must check the positive-response status before beginning work where required. This statewide utility-notice framework is separate from local fence permitting, zoning, development approval, easement limits, right-of-way approvals, floodplain review, stormwater review, drainage review, historic or design review, HOA restrictions, and other applicable requirements.

FENCE HEIGHT AND VISIBILITY RULES

• Maximum Fence Height: Constructed fences may not exceed 8 feet in height. Fence height is measured from ground level to the top of the fence.

• Fence Posts: Posts may extend no more than 8 inches above the top of the fence.

• Front-Yard and Street-Adjacent Privacy Fences: A privacy fence enclosing a front yard or placed adjacent to a street right-of-way may not exceed 4 feet. A street-adjacent fence greater than 4 feet must be placed at the building setback line.

• Building-Permit Exemption Threshold: The 7-foot exemption in 2018 International Building Code Section 105.2 is a building-permit exemption, not the county zoning maximum. Section 822 allows constructed fences up to 8 feet, but Harrison County does not publish an affirmative building-permit trigger for the over-7-foot range in the referenced published materials.

• Corner-Lot Visibility: Within the required 25-foot sight triangle, walls, fences, signs, structures, and plant growth may not obstruct sight lines at elevations over 2 feet 6 inches above any portion of the crown of the adjacent roadways.

MATERIAL AND CONSTRUCTION LIMITS

• Prohibited Fence Types: Electrified, barbed-wire, razor-wire, and stockade fences are prohibited in all zoning districts except when used in conjunction with an agricultural or industrial use. The exception does not make those fence types permitted for an ordinary residential use that is not agricultural.

• Finished Side: The code encourages fences to be installed with the finished side facing the adjacent property or arterial street. It states this as an encouraged orientation rather than a mandatory finished-side requirement.

• Landscaped Berms: Berms topped with landscaping are treated as fences and are subject to the applicable fence standards.

• Drainage-Easement Construction: Fencing in a public or private drainage easement may not use a material that obstructs above-ground water flow, and a fence along a drainage or utility easement must provide a maintenance gate.

• Other Standard Materials: Outside the prohibited fence types, drainage-easement conditions, and site-specific SmartCode standards, the code does not establish a general residential prohibition on wood, vinyl, ornamental metal, masonry, or chain-link fencing.

PRIVATE RESTRICTIONS

Private restrictions operate independently from Harrison County fence rules. These may include HOA covenants, subdivision restrictions, deed restrictions, private easements, architectural-review covenants, utility or drainage easements, conservation easements, agricultural agreements, and private boundary agreements.

A private restriction may impose a lower height, different material, additional setback, design-review requirement, or other limitation even when a fence complies with the Harrison County Unified Development Code.

REVIEW AND ENFORCEMENT CONTEXT

Fence issues are typically reviewed during permit or approval review when required, and through complaint-based code enforcement. Examples include:

• Fence Height and Street Placement: Whether a fence exceeds the 8-foot maximum, whether a front-yard or street-adjacent privacy fence exceeds 4 feet, or whether a taller street-adjacent fence is placed in front of the building setback line.

• Building-Code Permit Context: Whether the fence is within the 7-foot building-permit exemption in 2018 International Building Code Section 105.2. The referenced published materials do not state an affirmative permit trigger for fences over that threshold.

• Corner-Lot Visibility: Whether a fence or related obstruction interferes with sight lines above 2 feet 6 inches within the required 25-foot corner sight triangle.

• Drainage and Easements: Whether a fence obstructs an above-ground drainage easement, lacks a required maintenance gate along a drainage or utility easement, or involves grading or excavation that affects a creek, stormwater channel, or drainage facility.

• Floodplain and Coastal Review: Whether fence-related excavation, drilling, grading, fill, clearing, shoreline work, or other development occurs in a Special Flood Hazard Area or affects regulated coastal wetlands.

• SmartCode Frontage: Whether a property lies within a SmartCode Special Use District and is subject to a Porch & Fence or Common Yard private-frontage standard.

• Materials and Construction: Whether prohibited electrified, barbed-wire, razor-wire, or stockade fencing is proposed for a nonagricultural residential use, and whether the finished-side and landscaped-berm provisions are addressed.

• Private Restrictions and Utility Safety: Whether an HOA covenant, deed restriction, easement, or other private agreement imposes additional limits, and whether excavation requires Mississippi 811 notice and positive-response review.
