FENCE RULES – FORREST (COUNTY), MISSISSIPPI
OVERVIEW
Residential fences are permitted on private property within Forrest County, subject to local regulations.
This page applies to properties in the unincorporated areas of Forrest County; incorporated municipalities such as Hattiesburg and Petal may regulate fences under their own ordinances.
Fence-related requirements for Forrest County appear primarily in the Forrest County Planning Department materials, the Floodplain Damage Prevention Ordinance, the Ordinance for Stormwater Runoff, Illicit Discharges, and Illegal Connections, the Subdivision Regulations, and county road and drainage materials. Forrest County does not publish a consolidated residential fence code, a county zoning ordinance, 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.
Compiled From Forrest County Planning Department, Forrest County Floodplain Damage Prevention Ordinance, Forrest County Ordinance for Stormwater Runoff, Illicit Discharges, and Illegal Connections, Forrest County Subdivision Regulations, Forrest County Summary of Development Process, Forrest County Roads and Bridges Department, City of Hattiesburg official municipal materials, City of Petal official municipal materials, and Mississippi Damage Prevention Law / Mississippi 811 as of July 2026.
GOVERNANCE
The Forrest County Board of Supervisors governs county matters in unincorporated Forrest County. The Forrest County Planning Department administers county floodplain management, coordinates Phase II stormwater functions, supports subdivision review and mapping, and directs property owners to contact the department before development to confirm compliance with county ordinances.
The Planning Department expressly states that it does not issue certificates of occupancy or administer building codes. The referenced published materials do not identify the residential building code currently administered by Forrest County or establish a code-specific building-permit exemption for fences. The county construction-code posture is therefore No Local Code Status Published / Unclear for this page.
The Floodplain Damage Prevention Ordinance designates the Forrest County Planning Director or designee as the Floodplain Administrator. The Stormwater Runoff Ordinance is administered by the Forrest County Board of Supervisors or its designee.
The Forrest County Roads and Bridges Department maintains county roads, roadside drainage, culverts, and county rights-of-way. The referenced published materials do not publish a fence-specific county right-of-way setback or ordinary fence encroachment permit.
PERMIT AND APPROVAL REQUIREMENTS
• Building-Code Administration Context: The Forrest County Planning Department states that it does not issue certificates of occupancy or administer building codes. The referenced published materials do not identify the residential building code currently administered by Forrest County and do not establish a code-specific building-permit exemption or affirmative building-permit trigger for standard residential fences.
• Standard Residential Fence Permit: Outside the site-specific floodplain and land-disturbance conditions stated below, Forrest County does not publish a separate county fence permit, zoning permit, zoning certification, or building permit requirement for standard residential fences in the referenced published materials.
• General Development Contact: The Forrest County Planning Department directs property owners to contact the department before any development to confirm compliance with the county stormwater, floodplain-development, and subdivision ordinances. The referenced published materials do not state that this direction creates a separate general fence permit for every standard residential fence.
• Floodplain Development Permit: A floodplain development permit is required before development activities begin in identified Special Flood Hazard Areas and Community Flood Hazard Areas within county jurisdiction. The ordinance defines development to include excavation, drilling, filling, grading, paving, and other man-made changes to real estate. Fence work involving those activities in an identified flood-hazard area is subject to review by the Forrest County Floodplain Administrator.
• Stormwater Notification: The stormwater ordinance defines land-disturbance activity to include grading, digging, cutting, scraping, excavation, placement of fill, construction, substantial vegetation removal, and diversion or piping of a watercourse. For a project disturbing 0 to 0.9 acre, no stormwater permit or Stormwater Pollution Prevention Plan is currently required, but notification to the Forrest County Planning Department is required.
• Larger Land-Disturbance Projects: A project disturbing 1 to 5 acres requires a permit from the Forrest County Planning Department together with a Construction Notice of Intent and Stormwater Pollution Prevention Plan. A project disturbing more than 5 acres requires a permit from the Mississippi Department of Environmental Quality, with the required documents also provided to the county.
FENCE PLACEMENT RULES
• Property Lines: The referenced published materials do not specify 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.
• Flood-Hazard Areas: The floodplain ordinance defines an obstruction to include a fence where its location or characteristics may affect floodwater flow. A fence in an identified Special Flood Hazard Area or Community Flood Hazard Area may require floodplain review when it constitutes an obstruction or involves excavation, drilling, filling, grading, or another defined development activity.
• Regulatory Floodways: Encroachments, including fill, new construction, substantial improvements, and other development, are prohibited in a designated regulatory floodway unless certification with supporting technical data from a registered professional engineer demonstrates that the encroachment will cause no increase in flood levels during the base-flood discharge.
• Streams Without Base-Flood Elevations or Floodways: A covered fence or other encroachment may not be placed within a distance from the stream bank equal to five times the stream width at the top of the bank or 25 feet from the top of the bank, whichever is greater, unless a registered professional engineer certifies that the encroachment will not increase flood levels during the base-flood discharge.
• Drainage and Watercourses: Property owners must keep the portion of a watercourse crossing their property free of trash, debris, excessive vegetation, and other obstacles that would significantly retard water flow. Existing private structures within or adjacent to a watercourse must be maintained so they do not become hazards to the watercourse’s use, function, or physical integrity.
• County Roads and Rights-of-Way: The Forrest County Roads and Bridges Department maintains county roads, roadside drainage, culverts, and county rights-of-way. The referenced published materials do not specify a fence setback from county road rights-of-way or publish an ordinary fence encroachment permit.
• 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: Forrest County does not publish a defined maximum height for standard residential fences in the referenced published materials.
• Yard-Based Height: The referenced published materials do not specify separate county height limits for front-yard, side-yard, rear-yard, corner-lot, rural residential, agricultural residential, or large-lot fences.
• Visibility: The referenced published materials do not specify a county clear-vision, sight-triangle, driveway-visibility, alley-visibility, or intersection-visibility standard for standard residential fences.
• Floodplain Context: The floodplain ordinance’s treatment of a fence as a possible obstruction concerns floodwater flow and encroachment review. It is not a countywide maximum-height rule for residential fences.
MATERIAL AND CONSTRUCTION LIMITS
• Standard Materials: Forrest County does not publish a defined countywide residential fence material or construction standard in the referenced published materials.
• Prohibited Materials: The referenced published materials do not specify county residential standards for wood, vinyl, chain link, masonry walls, electric fencing, barbed wire, razor wire, opacity, finished-side orientation, gates, columns, or decorative features.
• Flood-Flow Construction Context: Within regulated flood-hazard areas, fence design and placement may be reviewed when the fence could obstruct floodwater, alter flow capacity, collect debris, or function as an encroachment. This floodplain standard does not create a countywide material prohibition for fences outside the regulated area.
• Pool Barriers: Forrest County does not publish a county pool-barrier standard for private residential pool fences in the referenced published materials.
PRIVATE RESTRICTIONS
Private restrictions operate independently from Forrest County ordinances and administrative review. HOA covenants, subdivision restrictions, deed restrictions, private easements, architectural-review covenants, agricultural agreements, boundary agreements, recorded agreements, conservation easements, and similar private rules may be more restrictive than county-published standards.
Private restrictions are not treated as Forrest 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:
• County Location: Whether the property is in unincorporated Forrest County or inside an incorporated municipality such as Hattiesburg or Petal with separate municipal administration.
• Building-Code Administration: The Forrest County Planning Department states that it does not issue certificates of occupancy or administer building codes, and the referenced published materials do not identify a county residential code or code-specific fence-permit exemption.
• Floodplain Permit Review: Fence work involving defined development activity in an identified Special Flood Hazard Area or Community Flood Hazard Area is reviewed through the county floodplain-development permit process.
• Floodway and Stream Encroachment: Review may address the no-rise certification required for regulatory-floodway encroachments and the five-times-stream-width or 25-foot limitation for covered encroachments along streams without established base-flood elevations or floodways.
• Stormwater and Land Disturbance: Review may address Planning Department notification for 0 to 0.9 acre of disturbance, the county permit and stormwater-plan requirements for 1 to 5 acres, and Mississippi Department of Environmental Quality permitting for more than 5 acres.
• Drainage, Watercourse, and Road Context: Review may address obstructions that significantly retard water flow, hazards created by structures within or adjacent to watercourses, roadside drainage, culverts, and county right-of-way conditions.
• Utility Safety: Mississippi 811 notice and positive-response requirements apply when fence work involves excavation covered by the Mississippi Underground Utility Damage Prevention Act.
