FENCE RULES – UNION (COUNTY), SOUTH CAROLINA
OVERVIEW
Residential fences are permitted on private property within the unincorporated areas of Union County, South Carolina, subject to local regulations.
The County maintains a focused regulatory footprint regarding residential fencing, prioritizing structural safety and public visibility over aesthetic mandates. Because Union County does not maintain a standalone fence ordinance for standard residential districts in unincorporated areas, the regulatory framework relies primarily on state-adopted building codes and general safety standards to ensure the protection of the traveling public. Properties located within municipal limits—such as the City of Union, Jonesville, or Carlisle—follow their respective town ordinances rather than County rules.
Compiled from the Union County Code of Ordinances and the Building Maintenance and Code Enforcement department guidelines, as of February 2026.
GOVERNANCE
South Carolina does not publish a statewide residential fence code. For properties located within Union County’s unincorporated jurisdiction, fence standards are administered by the Union County Building Maintenance Department and Code Enforcement.
Governance is established through the Union County Code of Ordinances, specifically Chapter 6 regarding Buildings and Building Regulations. The Building Official is the authority responsible for the administration and enforcement of these regulations. In the absence of local zoning specifically for residential fencing, the County enforces the state-adopted International Residential Code (IRC) for structural safety. County requirements do not override homeowners association (HOA) requirements or private covenants.
PERMIT AND APPROVAL REQUIREMENTS
Union County utilizes structural height thresholds to determine when formal oversight is required for a residential fence.
• Building Permit Exemption: In accordance with technical code adoptions, a building permit is NOT REQUIRED for standard residential fences that do not exceed 7 feet in height.
• Permit Requirement: Any fence or wall structure 7 feet in height or greater requires a building permit prior to construction to ensure wind-load stability and structural integrity.
• Zoning Compliance: Building permit requirements are separate from zoning, setback, or plat requirements. Confirm any applicable zoning conditions, setbacks, and plat requirements with Union County Building Maintenance Department and Code Enforcement before construction.
• Contractor Requirements: Any contractor hired to perform fence installation for a fee must possess a valid Union County Business License.
• Swimming Pool Barriers: Fences serving as safety barriers for swimming pools or spas must comply with specific structural and height requirements (minimum 48 inches) as defined in the adopted building codes, regardless of the 7-foot permit threshold.
FENCE PLACEMENT RULES
Fences must be situated entirely on the owner’s private property and must not interfere with public infrastructure or utility access.
• 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.
• Rights-of-Way: No fence or wall may be placed within a public right-of-way or in any location that obstructs public sidewalks or roadways.
• 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: Fences should not be constructed in a manner that obstructs natural drainage flow or interferes with established utility or maintenance easements.
FENCE HEIGHT AND VISIBILITY RULES
The County regulates height and visibility primarily through structural safety thresholds and intersection visibility standards.
• Structural Height Threshold: Residential fences are permitted to be constructed up to 7 feet in height without requiring a structural permit or engineering review.
• Intersection Visibility (Sight Triangle): No fence, wall, or obstruction shall be erected or maintained in a manner that obstructs the view of motorists at street intersections or driveway exits.
• Safety Zones: On corner lots, specific vision clearance must be maintained. Fences that create a “blind spot” or traffic hazard are addressed through required modification or removal to ensure the safety of the traveling public.
• Height Measurement: Height is measured from the finished grade at the base of the fence to the highest point of the structure.
MATERIAL AND CONSTRUCTION LIMITS
Union County provides property owners with broad discretion regarding materials while requiring structures to be kept in a safe condition.
• Approved Materials: Union County does not define permitted or prohibited fencing materials for standard residential use in unincorporated districts.
• Construction Quality: All fences must be constructed in a safe and structurally sound manner. Fences must be able to withstand local weather conditions and should not pose a collapse hazard to neighbors or the public.
• Maintenance: Under general property maintenance standards, fences must be kept in a good state of repair. Fences that become dilapidated, leaning, or pose a safety hazard may be declared a public nuisance.
PRIVATE RESTRICTIONS
Homeowners association (HOA) requirements and private covenants operate independently from Union County regulations. Because the County’s regulatory footprint is limited, private subdivisions often utilize covenants to impose restrictions that the County does not, such as prohibiting chain link, requiring specific wood stains, or limiting fence height to 4 feet in front 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 neighborhood-specific 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:
The Building Maintenance Department and Code Enforcement maintain oversight through inspections and reactive enforcement.
• Installing a fence 7 feet or taller without a required building permit.
• Constructing a fence that obstructs visibility at an intersection, creating a traffic hazard.
• Placement of a fence within a public right-of-way or over a recorded utility easement.
• Allowing a fence to fall into a state of disrepair that constitutes a safety violation or public nuisance.
