FENCE RULES – HANCOCK (COUNTY), MISSISSIPPI
OVERVIEW
Residential fences are permitted on private property within Hancock County, subject to local regulations.
This page applies to properties in the unincorporated areas of Hancock County; incorporated municipalities such as Bay St. Louis and Diamondhead may regulate fences under their own ordinances.
Fence-related requirements for Hancock County appear primarily in the Hancock County Zoning Ordinance, the Flood Damage Prevention Ordinance, the Post Construction Run-Off and Erosion Control Ordinance, the Subdivision and Pier Regulations, county permit and stormwater materials, and the county Planning & Zoning Department and Roads & Bridges Department. Hancock County does not publish a consolidated residential fence chapter or a separate standard residential fence-permit page 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.

GOVERNANCE
The Hancock County Board of Supervisors governs county matters in unincorporated Hancock County. The Hancock County Planning & Zoning Department includes the Building Department and Zoning Department and administers local building permits, zoning, floodplain, stormwater, and development-review functions.
The Building Department states that Hancock County currently follows the 2018 International Building Code and 2018 International Residential Code and issues residential and commercial building permits. The 2018 IRC includes a building-permit exemption for fences not over 7 feet high. The referenced published materials do not state whether the county’s current code administration reflects participation in, or a prior statutory opt-out from, Mississippi’s State Uniform Construction Code framework.
The Zoning Department administers the Hancock County Zoning Ordinance. The Building Official or designee serves as the Flood Damage Prevention Ordinance Administrator, and the county Building Office processes the stormwater and land-disturbance materials identified in the Post Construction Run-Off and Erosion Control Ordinance. The Hancock County Planning Commission and Board of Supervisors administer subdivision review.
The Hancock County Roads & Bridges Department maintains county roads, roadside drainage, culverts, and related public infrastructure. The Mississippi Department of Marine Resources is the point of contact for wetlands permits in the Mississippi Coastal Zone, including Hancock County.
PERMIT AND APPROVAL REQUIREMENTS
• Building-Code Permit Context: Hancock County administers the 2018 International Residential Code. That code includes a building-permit exemption for fences not over 7 feet high. Hancock County does not publish a separate local fence permit requirement for standard residential fences. The exemption is not a zoning height allowance and is not converted here into an affirmative permit requirement for fences over 7 feet.
• General Permit Form Context: Hancock County publishes a Building & Zoning Permit Application for new residential and commercial structures and a New Residential Construction checklist, but neither document explicitly identifies a standard residential fence as work requiring those forms.
• 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 Hancock County Planning & Zoning Department before construction.
• Floodplain Development Permit: A Floodplain Development Permit is required before development begins in identified Special Flood Hazard Areas. The ordinance defines development to include buildings or other structures, filling, grading, paving, excavation, and drilling, and defines an obstruction to include a fence in, along, across, or projecting into a watercourse when it may alter or impede flow or collect debris. Fence work meeting those conditions is reviewed by the Flood Damage Prevention Ordinance Administrator.
• Stormwater and Land-Disturbance Context: The Post Construction Run-Off and Erosion Control Ordinance defines land-disturbance activity to include grading, digging, cutting, scraping, excavation, fill, construction, substantial vegetation removal, and diversion or piping of a watercourse. The county’s Storm Water Management materials direct development or drainage projects between 1 and 5 acres to the county and projects greater than 5 acres to the state permitting process. The referenced published materials do not explicitly state that ordinary fence-post excavation by itself requires a separate county stormwater permit.
• Coastal Wetlands Permit Context: Hancock County lies within the Mississippi Coastal Zone. Applications for wetland impacts are submitted through the Mississippi Department of Marine Resources. Fence-related excavation, clearing, fill, access work, shoreline work, or placement affecting coastal wetlands, marshes, tidal areas, waterways, or submerged lands may require wetlands review; this is not an ordinary fence permit for established upland lots.
FENCE PLACEMENT RULES
• Property Lines: The zoning 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.
• Corner-Lot Sight Triangle: On a corner lot where a front and side yard are required, no wall, fence, sign, structure, or plant growth may obstruct sight lines at elevations over 2 feet 6 inches above 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.
• Special Flood Hazard Areas: Fence placement in an identified Special Flood Hazard Area is subject to floodplain permit review when it involves a defined development activity or creates a watercourse obstruction.
• Regulatory Floodways: Within a regulatory floodway, encroachments, including fill, new construction, substantial improvements, and other development, are prohibited unless a registered professional engineer supplies supporting technical data demonstrating no increase in flood levels during the base-flood discharge.
• Streams Without Base-Flood Elevations or Floodways: Where no base-flood elevation or floodway data are available, no encroachment, including fill or other development, may be located within a distance from the stream bank equal to 5 times the stream width at the top of the bank or 20 feet on each side from the top of the bank, whichever is greater, unless a registered professional engineer certifies that the encroachment will cause no increase in flood levels during the base-flood discharge.
• County Roads and Drainage: The Hancock County Roads & Bridges Department maintains county roads and drainage, but the referenced published materials do not specify a fence setback from county road rights-of-way or publish an ordinary fence encroachment permit.
• Coastal Wetlands: Fence-related work affecting coastal wetlands or waterways is subject to separate Mississippi Department of Marine Resources review. The referenced published materials do not state a coastal-wetlands setback as a countywide rule for established upland residential fences.
• 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 Height: The zoning ordinance does not specify a maximum height for standard residential fences.
• Yard-Based Height: The zoning ordinance does not specify separate front-yard, side-yard, or rear-yard height limits for standard residential fences.
• Corner-Lot Visibility: Within the 25-foot sight triangle, a fence may not obstruct sight lines at elevations over 2 feet 6 inches above the crown of the adjacent roadways.
• Building-Code Exemption: The 2018 IRC exemption for fences not over 7 feet high is a building-permit exemption, not a maximum permitted fence height and not an affirmative Hancock County permit trigger for fences over 7 feet.
MATERIAL AND CONSTRUCTION LIMITS
• Standard Materials: The zoning ordinance does not specify a general residential fence material or construction standard.
• General Material Prohibitions: Outside the limited subdivision drainage-safety requirement below, the zoning ordinance does not publish general residential prohibitions for wood, vinyl, chain link, electric fencing, barbed wire, razor wire, opacity, finished-side orientation, gates, columns, or decorative features.
• Subdivision Drainage-Safety Fencing: When fencing is required as a subdivision improvement adjacent to an open drainage canal, ditch, or borrow pit, the Subdivision and Pier Regulations require the subdivider to construct a galvanized chain-link fence at least 7 feet high, topped with 3 strands of barbed wire, with removable sections located and constructed in a manner acceptable to the Board of Supervisors or other governmental agency having jurisdiction. This is a subdivision drainage-safety requirement, not the general standard for an ordinary residential yard fence.
• Floodplain and Watercourse Construction Context: A fence in, along, across, or projecting into a watercourse may be regulated as an obstruction when its location or characteristics may alter or impede water flow or collect debris. This floodplain standard does not create a countywide material prohibition for fences outside the regulated area.
PRIVATE RESTRICTIONS
The Subdivision and Pier Regulations require proposed subdivision materials to include restrictive-covenant information. Those covenants, HOA rules, deed restrictions, private easements, architectural-review covenants, agricultural agreements, private boundary agreements, recorded agreements, conservation easements, and similar private restrictions operate independently from Hancock County review and may be more restrictive than county-published standards.
Private restrictions are not treated as Hancock County permit approvals unless the county’s published materials expressly make them part of county review.
REVIEW AND ENFORCEMENT CONTEXT
Fence issues are typically reviewed during permit or approval review when required, and through complaint-based code enforcement. Examples include:
• Building-Code Permit Context: Whether the proposed fence falls within the 2018 IRC exemption for fences not over 7 feet high, without treating the exemption as a zoning height allowance or an affirmative permit trigger above 7 feet.
• Corner-Lot Visibility: Whether a wall, fence, sign, structure, or plant growth obstructs sight lines above 2 feet 6 inches within the required 25-foot corner sight triangle.
• Floodplain Permit and Watercourse Review: Whether the fence is located in a Special Flood Hazard Area, involves defined development activity, or may function as an obstruction in, along, across, or projecting into a watercourse.
• Floodway and Stream-Bank Review: Whether the project requires a no-rise certification in a regulatory floodway or complies with the 5-times-stream-width or 20-foot limitation where base-flood elevation and floodway data are unavailable.
• Stormwater and Land Disturbance: Whether fence-related work is part of a broader project involving regulated grading, excavation, fill, construction, drainage alteration, substantial vegetation removal, or a development or drainage project meeting county or state acreage thresholds.
• Subdivision Drainage-Safety Fencing: Whether required subdivision fencing adjacent to an open drainage canal, ditch, or borrow pit meets the 7-foot galvanized chain-link, 3-strand barbed-wire, and removable-section requirements.
• Road, Right-of-Way, and Easement Context: Whether the fence remains on private property and avoids county road rights-of-way, drainage areas, and recorded easements, even though no ordinary county fence encroachment permit or road setback is published.
• Coastal Wetlands: Whether fence-related excavation, clearing, fill, access work, shoreline work, or placement affects wetlands within the Mississippi Coastal Zone and requires review through the Mississippi Department of Marine Resources.
• Private Restrictions: Whether HOA covenants, subdivision restrictions, deed restrictions, easements, or other private agreements impose additional height, material, placement, or design limits.
• Utility Safety: Whether the project involves digging, drilling, augering, boring, grading, or other excavation requiring Mississippi 811 notice and positive-response review.
