FENCE RULES – MERCER (COUNTY), WEST VIRGINIA
OVERVIEW
Residential fences are permitted on private property within the unincorporated portions of Mercer County, subject to applicable county and state requirements. The incorporated municipality of Bluefield may regulate fences under its own ordinances.
This page applies to the unincorporated portions of Mercer County. The referenced published materials do not establish a general county zoning ordinance for standard residential fences; incorporated municipalities regulate property within their own boundaries, and separate floodplain, road, utility, statewide fence-law, or private requirements may still apply where published.
Mercer County does not publish a consolidated residential fence code, fence-specific permit page, or general county zoning ordinance. The August 2018 Comprehensive Plan treated zoning and subdivision regulations as possible future tools rather than existing controls, and January 2024 County Commission minutes state that there were no zoning laws in the county.
This page focuses on typical single-family residential fencing. If the jurisdiction’s code, ordinance, or zoning materials do not state a specific limit or requirement, this page notes that the controlling regulatory text does not specify one. If no local code, ordinance, or zoning text 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 the Mercer County Government and Ordinance Directory, Mercer County Planning Commission materials, Mercer County Comprehensive Plan, January 2024 and March 2019 County Commission minutes, Mercer County Abandoned and Dilapidated Building Ordinance, Mercer County Floodplain Ordinance and Floodplain Administration information, West Virginia State Building Code materials, West Virginia 811 requirements, West Virginia fence statutes, contractor-licensing law, and WVDOH encroachment materials as of July 2026.
GOVERNANCE
The Mercer County Commission is the governing authority for unincorporated Mercer County. The Mercer County Planning Commission develops and maintains comprehensive planning strategy, but the referenced published materials do not establish that it administers a zoning ordinance, zoning map, fence permit, or certificate-of-zoning-compliance process.
The August 2018 Comprehensive Plan stated that there were no plans to pursue countywide zoning, while partial zoning near interstate interchanges was discussed only as an option. It also described subdivision regulations as a measure the county might consider. January 2024 County Commission minutes later stated, “No zoning laws in the County now.”
The Mercer County Abandoned and Dilapidated Building Ordinance applies to unincorporated territory but expressly states that it does not implement zoning restrictions or building-code restrictions. Its definition of structure excludes fences. That ordinance therefore does not create an ordinary residential fence code or fence-permit process.
The referenced published materials do not establish that Mercer County has adopted and currently enforces the West Virginia State Building Code. No county adoption order, code-enforcement department, applicable code edition, inspection program, or intergovernmental enforcement agreement is published in the referenced materials.
Floodplain review is administered through Mercer County Floodplain Management. Mercer County identifies Keith Gunnoe as County Floodplain Manager. State highway rights-of-way and qualifying road encroachments remain subject to the West Virginia Division of Highways.
PERMIT AND APPROVAL REQUIREMENTS
• Standard Residential Fences: Mercer County does not publish a fence-specific permit, zoning permit, certificate of zoning compliance, or general development approval requirement for standard residential fences in the unincorporated county territory.
• State Building Code Context: The referenced published materials do not establish that Mercer County has adopted and enforces the West Virginia State Building Code and do not publish a separate local building-permit requirement for standard residential fences.
• Floodplain Development Permit: The Mercer County Floodplain Ordinance requires a development permit and site-plan approval before development in regulated flood-hazard areas. Fence installation involving excavation, drilling, grading, fill, or another man-made site change is subject to county floodplain review when it constitutes development within a mapped floodplain. The ordinance does not publish a fence-specific floodplain standard.
• Floodway and Watercourse Conditions: Development governed by the Floodplain Ordinance may not encroach into a mapped floodway unless engineering analysis demonstrates no increase in the base flood elevation. The ordinance also maintains a flood protection setback equal to twice the watercourse channel width or 50 feet, whichever is less, measured from the top of the banks. These are floodplain-development conditions, not general county fence setbacks.
• Road and Right-of-Way Work: A fence, gate, post, excavation, or other work proposed within a state highway right-of-way or affecting highway access, drainage, shoulders, ditches, or culverts may require separate approval from the West Virginia Division of Highways.
• Paid Installation: West Virginia contractor-licensing law applies to a person who, for compensation, undertakes covered residential work costing $5,000 or more. The statutory contractor definition excludes a person who personally performs construction work on real property the person owns or leases. Contractor licensing is separate from county permits, site restrictions, and other approvals.
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.
• Floodplain and Stream Areas: In regulated flood-hazard areas, fence installation involving excavation, drilling, grading, fill, or other development is subject to county floodplain review. The flood protection setback described above applies only where the Floodplain Ordinance governs the proposed development.
• Floodway Encroachments: Fence-related excavation, fill, or other development that would create an encroachment in a mapped floodway is subject to the ordinance’s engineering no-rise requirement.
• State Highways and Rights-of-Way: Fence placement must not obstruct a public highway, shoulder, ditch, culvert, drainage facility, or access area. WVDOH approval is separate from county administration where proposed work affects a state-maintained right-of-way.
• Utility Safety: West Virginia law requires notice through West Virginia 811 before excavation or demolition where the Underground Facilities Damage Prevention Act applies. For covered fence work involving digging, drilling, augering, boring, trenching, grading, or other excavation, notice must be given not less than 48 hours, excluding Saturdays, Sundays, and federal or state legal holidays, and not more than 10 workdays before work begins. A change in the proposed starting date or time requires at least 24 hours‘ advance notice, excluding Saturdays, Sundays, and legal holidays. West Virginia 811 notice is separate from local fence permitting, zoning approval, building-code review, easement limits, right-of-way or WVDOH approval, floodplain review, stormwater review, drainage review, historic or design review, HOA restrictions, and other applicable requirements.
FENCE HEIGHT AND VISIBILITY RULES
Mercer County does not publish a defined maximum height for standard residential fences in the referenced published materials.
The referenced published materials do not establish separate front-yard, side-yard, rear-yard, corner-lot, driveway-visibility, clear-vision, or sight-triangle fence limits for the unincorporated county territory.
The 7-foot building-permit exemption contained in the incorporated 2018 residential and building codes is not presented as a Mercer County rule because local State Building Code adoption and enforcement were not confirmed.
MATERIAL AND CONSTRUCTION LIMITS
Mercer County does not publish defined material, opacity, finished-side, orientation, gate, post-spacing, masonry-wall, barbed-wire, razor-wire, electric-fence, or security-fence standards for ordinary residential lots in the referenced published materials.
West Virginia’s lawful-fence and agricultural partition-fence statutes contain specialized standards for livestock and agricultural boundaries. Those standards do not operate as ordinary residential subdivision or city-lot fence rules.
The referenced published materials do not establish a Mercer County residential pool-barrier standard or locally administered pool-code requirement.
PRIVATE RESTRICTIONS
HOA covenants, subdivision restrictions, deed restrictions, private easements, architectural-review covenants, acknowledged agricultural partition-fence agreements, conservation easements, and other private agreements operate independently of county administration and may be more restrictive than the published governmental requirements.
Mercer County does not enforce a private restriction merely because it affects fence location, height, materials, or appearance unless an official source establishes a separate governmental role.
REVIEW AND ENFORCEMENT CONTEXT
Fence issues are typically reviewed during permit or approval review when required, and through complaint-based code enforcement. Examples include:
• Floodplain Development: Fence-related excavation, drilling, grading, fill, or other development in regulated flood-hazard areas.
• Floodway and Watercourse Conditions: Encroachments in mapped floodways and development within the Floodplain Ordinance’s flood protection setback.
• Road and Drainage Conflicts: Encroachments into public rights-of-way, highway shoulders, ditches, culverts, drainage areas, or access points.
• Boundary and Easement Conflicts: Fence placement beyond the owner’s property or within a recorded easement or right-of-way.
• Utility Excavation: Covered digging or excavation performed without the required West Virginia 811 notice.
• Rural and Agricultural Conditions: Livestock containment, lawful-fence standards, agricultural partition fences, hedge fences, stream boundaries, cattle guards, or other specialized state-law contexts.
• Private Restrictions: HOA, deed, subdivision, easement, or private-agreement requirements that operate separately from county rules.
