FENCE RULES – BARNWELL (COUNTY), SOUTH CAROLINA
OVERVIEW
Residential fences are permitted on private property within the unincorporated areas of Barnwell County, South Carolina, subject to local regulations.
The County regulates fences as structures to ensure they do not create safety hazards at intersections or interfere with public infrastructure. Properties located within municipal limits—such as the City of Barnwell, Blackville, or Williston—follow their respective town ordinances rather than County regulations.
Compiled from the Barnwell County Zoning Ordinance and the Barnwell County Land Development Regulations, as of February 2026.
GOVERNANCE
South Carolina does not publish a statewide residential fence code. For properties located within Barnwell County’s unincorporated jurisdiction, fence standards are administered by the Barnwell County Building and Zoning Department.
Primary governance is established through the Barnwell County Zoning Ordinance. The Zoning Administrator is the official charged with the administration and enforcement of these regulations. Technical safety and structural standards follow the state-adopted International Residential Code (IRC). County requirements do not override homeowners association (HOA) requirements or private covenants.
PERMIT AND APPROVAL REQUIREMENTS
Barnwell County uses technical definitions to establish regulatory authority, and administrative requirements for standard residential fencing differ from primary structures.
• Building Permit: In accordance with state-adopted technical codes, a structural building permit is required if a fence exceeds 7 feet in height or for masonry/concrete walls that require structural footings.
• Administrative Compliance: Property owners are responsible for ensuring that fence placement and height adhere to codified standards for setbacks and visibility. Barnwell County Building & Zoning may confirm setbacks, overlays, and zoning permitting needs.
• Zoning Compliance: Written approval from the Zoning Administrator may be required for projects in certain overlay districts or those involving non-standard heights to ensure compliance with the official zoning map and safety mandates.
FENCE PLACEMENT RULES
Fences must be situated entirely on the owner’s private property and must not interfere with public infrastructure or roadway safety.
• 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.
• Utility Notification: South Carolina state law mandates that SC 811 be contacted at least three full business days prior to breaking ground on any fence project. The required waiting period excludes the day of the notice, weekends, and holidays, allowing utility operators time to verify and mark underground lines. Excavators must strictly adhere to the “tolerance zone” by utilizing only hand tools or soft digging methods within 24 inches of any utility indicators.
• Easements and Drainage: No fence or structure may be constructed in a manner that obstructs natural drainage flow or interferes with recorded utility or maintenance easements.
• Setbacks: Fences are permitted as allowable encroachments into required yard setbacks provided they do not violate visibility mandates.
FENCE HEIGHT AND VISIBILITY RULES
The County enforces safety envelopes to protect motorists at intersections and to ensure structures do not impede vision clearance.
• Intersection Visibility (Sight Triangle): On any corner lot, no fence, wall, or obstruction is permitted between the heights of 2.5 feet and 10 feet above the center line grades of the intersecting streets.
• Safety Dimensions: This restriction applies to the triangular area bounded by the street lines and a line joining points along said street lines 25 feet from the point of intersection.
• Standard Height: Standard fences are permitted up to 7 feet without a structural permit. Any fence exceeding 7 feet requires a building permit.
• Accessory Heights: Fences are exempt from the primary structure height limits of a zoning district but must remain within safe structural and visibility bounds as determined by the Building Official.
MATERIAL AND CONSTRUCTION LIMITS
The County requires fences to be kept in a safe condition but does not define residential fencing materials.
• Approved Materials: Barnwell County does not define permitted or prohibited fencing materials for standard residential use.
• Construction Quality: All fences must be constructed in a safe and structurally sound manner and must not pose a collapse hazard to the public.
• Maintenance: Property owners are responsible for maintaining fences in a good state of repair. Fences that become dilapidated or pose a safety hazard may be subject to code enforcement action under the County’s property maintenance standards.
PRIVATE RESTRICTIONS
Homeowners association (HOA) requirements and private covenants operate independently from Barnwell County regulations. Private rules often impose more restrictive standards, such as prohibiting specific materials (e.g., chain link), requiring specific wood stains, or limiting fence height to 4 feet in all yards. The County does not monitor or enforce private covenants; property owners are responsible for ensuring their project meets both County ordinances and any applicable HOA restrictions.
REVIEW AND ENFORCEMENT CONTEXT
Fence issues are typically reviewed during permit or approval review when required, and through complaint-based code enforcement. Examples include:
• Constructing a fence that obstructs the 25-foot sight triangle at an intersection.
• Placement of a fence within a public right-of-way or over a recorded drainage easement.
• Installing a fence that exceeds 7 feet in height without a required structural building permit.
• Allowing a fence to fall into a state of disrepair, constituting a public nuisance or safety hazard.
