FENCE RULES – ROANOKE (COUNTY), VIRGINIA

OVERVIEW

Residential fences are permitted on private property within Roanoke County, subject to local regulations.

This page applies to properties in the unincorporated areas of Roanoke County; incorporated towns, cities, or other municipalities may regulate fences under their own ordinances.

Local fence rules appear primarily in the Code of Roanoke County and the Roanoke County Zoning Ordinance. The zoning ordinance contains a specific fence location-and-design rule, a zoning-permit exception for conforming fences, sight-triangle limits, floodplain overlay provisions, and screening / buffer-yard standards that can affect fences used as required screening. Roanoke County Development Services and the Office of Building Safety also publish residential permit, pool-barrier, plot-plan, stormwater, drainage, and inspection materials.

This page focuses on typical single-family residential fencing. If the jurisdiction’s adopted materials do not state a specific limit or requirement, this page notes that the code does not specify one.

GOVERNANCE

Roanoke County’s local fence framework is administered through the Code of Roanoke County, the Roanoke County Zoning Ordinance, and related building, zoning, development, stormwater, drainage, and pool-barrier materials.

The Roanoke County Zoning Ordinance applies to property within the unincorporated portions of Roanoke County. The zoning administrator administers and enforces the zoning ordinance, issues or denies zoning permits and certificates of zoning compliance, inspects buildings and land, and interprets zoning provisions.

Roanoke County adopts the Virginia Uniform Statewide Building Code through Chapter 7 of the County Code. Roanoke County Development Services and the Office of Building Safety administer building-code, residential-permit, pool-barrier, plot-plan, and inspection materials where those materials apply.

Roanoke County does not publish a single consolidated residential fence code. Fence-related rules appear instead in the zoning-permit exception for fences, the fence location-and-design rule, sight-triangle standards, screening / buffer-yard standards, floodplain overlay provisions, erosion and stormwater provisions, drainage materials, pool-barrier materials, and certain animal-control or rural-use standards.

The zoning ordinance defines structures broadly, but it also states that walls and fences are not deemed structures except as otherwise specifically provided in the ordinance. That fence-specific language controls this page’s treatment of zoning permits and fence placement.

PERMIT AND APPROVAL REQUIREMENTS

• Building Permit Baseline: Under the Virginia Uniform Statewide Building Code baseline, application for a building permit and related inspections are not required for fences of any height, unless the fence is required for pedestrian safety during construction or is used as the barrier for a swimming pool. Roanoke County adopts the Virginia Uniform Statewide Building Code through Chapter 7 of the County Code and does not publish a stricter local residential fence building-permit threshold for standard yard fences in the referenced published materials.

• Zoning Permit: The Roanoke County Zoning Ordinance requires zoning permits for structures and land uses, but it expressly lists fences as a zoning-permit exception when their location and design conform to Section 30-92, Section 30-100-8, and Section 30-100-9. A standard residential fence that conforms to those sections is therefore not published as requiring a zoning permit.

• Pool, Spa, And Hot-Tub Barriers: A fence used as the required barrier for a regulated residential pool, spa, or hot tub is reviewed through the pool / hot-tub permit and final building / barrier inspection process. Roanoke County’s pool materials require permits for pools over 150 square feet, pools holding more than 5,000 gallons, or pools deeper than 24 inches, and require code-compliant barriers for pools, spas, and hot tubs unless an approved safety cover serves as the barrier.

• Stormwater / Land Disturbance: Roanoke County regulates land-disturbing activity at 2,500 square feet or more and certain common-plan development activity, but Chapter 8.1 states that installation, maintenance, or repair of fence and signposts is not required to comply with that chapter unless federal law requires otherwise. That fence-post exception does not replace review for broader grading, filling, drainage work, floodplain development, stream-buffer work, or other land-disturbing activity connected to a larger project.

• Floodplain Review: In the Floodplain Overlay District, all uses, activities, and development within a floodplain area must be undertaken only after the required permit is issued. Fence-related excavation, grading, fill, obstruction, or other work in a special flood hazard area or floodway may require floodplain review when it qualifies as development under the zoning ordinance.

• Private Stable / Animal-Enclosure Context: Private stable standards require a plot plan showing the location and type of fencing, require no more than one horse or pony per two fenced acres, and require confined areas and fencing to be securely constructed. Residential chicken and dangerous-dog enclosure rules are separate animal-control or use-specific standards, not ordinary yard-fence permit rules.

FENCE PLACEMENT RULES

• General Fence Location: Except where Section 30-92 screening / buffer-yard standards or Section 30-100-8 sight-triangle limits apply, the Roanoke County Zoning Ordinance states that fences may be constructed in any location, on any lot.

• 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.

• Front Building Line: On a lot occupied by a residential use type, a fence located in front of the building line is permitted only within the 4-foot height limit. The zoning ordinance defines the building line as the line parallel to the street right-of-way passing through the point of the principal building nearest the street right-of-way.

• Sight Triangles: At intersecting rights-of-way of any two public streets, a clear sight triangle is formed by 20-foot legs measured along each right-of-way line from the intersection point. Within that triangle, nothing over 3 feet high may be constructed, placed, or permanently parked, and vegetation may not grow above 3 feet.

• Required Screening / Buffer Yards: When Section 30-92 applies to a development, site-development plan, or special-use condition, fences used as required screening must fit the screening, buffer-yard, durability, opacity, and traffic-safety standards of that section. The ordinary fence-location rule is expressly subject to Section 30-92.

• Drainage, Plot Plans, And Easements: Roanoke County plot-plan and drainage materials require projects using those materials to show utilities and easements, streets and entrances, drainage arrows, disturbed area, E&S agreement status, and erosion-and-sediment controls where applicable. All collected stormwater must be discharged to an approved location, and flood hazards or steep slopes may require additional information.

• Floodplain / Watercourse Areas: In special flood hazard areas, floodways, watercourses, drainage ditches, and drainage facilities, fence-related development must not adversely affect channel, floodway, watercourse, drainage-ditch, or drainage-system capacity.

• Utility Safety: Virginia law requires notice to the notification center / Virginia 811 before excavation or demolition where the Underground Utility Damage Prevention Act applies. For fence projects that involve excavation, including digging, drilling, augering, or other movement of earth, the excavator must submit a locate request and must review the positive-response information before work begins unless an exemption applies. A Virginia locate request is generally valid for 15 working days, and re-marking may be required before that period ends or when markings become illegible. Virginia law includes an important exemption for hand digging performed by an owner or occupant of a property. This statewide utility-notice framework is separate from local fence permitting, zoning, development approval, easement limits, right-of-way approvals, floodplain review, Chesapeake Bay Preservation Area review, Resource Protection Area review, stormwater review, wetland or shoreline approvals, HOA restrictions, and other applicable requirements.

FENCE HEIGHT AND VISIBILITY RULES

• Front Of Building Line: On a residential lot, fences located in front of the building line must not exceed 4 feet in height.

• Side And Rear Areas: Outside the front-building-line rule, the code does not specify a separate maximum height for standard residential fences in the referenced published materials. The Virginia building-code baseline uses fences of any height only as a building-permit application exemption, not as a local zoning height limit.

• Sight Triangles: In the required sight triangle at intersecting public street rights-of-way, nothing over 3 feet high may be constructed, placed, permanently parked, or allowed to grow as vegetation.

• Pool, Spa, And Hot-Tub Barriers: Required residential pool, spa, and hot-tub barriers must be at least 48 inches above grade, measured from the side of the barrier facing away from the pool. Openings must not allow passage of a 4-inch-diameter sphere, and Roanoke County’s barrier materials include separate clearance, gate, latch, chain-link, lattice, clear-zone, and poolside-setback standards.

• Animal-Enclosure Heights: Residential chicken enclosures and coops may not exceed 10 feet in height. The code does not publish an ordinary residential yard-fence height rule from the chicken-enclosure standard.

MATERIAL AND CONSTRUCTION LIMITS

• Standard Residential Materials: The code does not specify a list of permitted or prohibited materials for standard residential fences.

• Finished Side / Orientation: The code does not specify a finished-side, opacity, or orientation requirement for standard residential fences.

• Barbed Wire, Razor Wire, And Electric Fences: The code does not specify a separate residential rule for barbed wire, razor wire, or electric fences in the referenced published materials.

• Required Screening Materials: Where Section 30-92 screening applies, screening must be visually opaque, constructed of durable material, installed within a required buffer yard, and continuously maintained. Acceptable screening materials include stockade fences, decorative masonry walls, brick walls, earth berms, and/or mixed evergreen and deciduous vegetation; alternative materials may be approved by the zoning administrator if their characteristics and design meet the section’s intent and standards.

• Pool-Barrier Construction: Pool, spa, and hot-tub barriers have separate construction standards. Chain-link mesh is limited to 1.75 inches measured along the horizontal axis; lattice openings may not exceed 1.75 inches; pedestrian gates must open outward away from the pool and be self-closing and self-latching; barriers must maintain a 36-inch exterior clear zone and be at least 36 inches from the property line unless a legal recorded easement is provided.

• Residential Chicken Enclosures: Residential chicken keeping requires hens to be kept in a predator-resistant coop or chicken enclosure, with coops and enclosures behind the front building line, at least 10 feet from side and rear property lines, at least 35 feet from any residential dwelling on an adjacent lot, and securely constructed.

• Dangerous-Dog Enclosures: A dangerous dog kept outdoors must be in a securely enclosed and locked pen or structure with secure sides and a secure top. If the enclosure has no bottom secured to the sides, the sides must be embedded into the ground at least 2 feet.

• Private Stable Fencing: Private stable standards require all confined areas and fencing to be securely constructed; perimeter fencing of a yard is not treated as a confined area for that section.

PRIVATE RESTRICTIONS

HOA covenants, subdivision restrictions, deed restrictions, private easements, architectural-review covenants, agricultural agreements, private boundary agreements, recorded drainage or access agreements, conservation easements, and other private restrictions operate independently of Roanoke County zoning and permit review and may be more restrictive than county rules.

Roanoke County’s drainageway provisions recognize that private easements, covenants, deed restrictions, and other recorded instruments may create separate drainageway maintenance obligations. The county code does not publish a general rule that private HOA or architectural covenants are enforced as county fence approvals for standard residential fences.

REVIEW AND ENFORCEMENT CONTEXT

Fence issues are typically reviewed during permit or approval review when required, and through complaint-based code enforcement. Examples include:

• Zoning Permit Exception: Conforming fences are listed as a zoning-permit exception only when their location and design comply with the screening / buffer-yard rule, sight-triangle rule, and fence location-and-design rule.

• Residential Height Review: Review may involve the 4-foot height limit for fences located in front of the building line on residential lots.

• Sight-Triangle Review: Review may involve the 20-foot public-street sight triangle and the 3-foot obstruction and vegetation limit within that triangle.

• Pool-Barrier Review: Review applies when a fence serves as a residential pool, spa, or hot-tub barrier, including permit, barrier-responsibility, clear-zone, gate, latch, inspection, and final-approval requirements.

• Screening / Buffer-Yard Review: Review may involve Section 30-92 when a fence is used as required screening or when a development, site-development plan, or special-use condition is subject to screening, landscaping, or buffer-yard standards.

• Stormwater And Drainage Review: Fence-post installation is exempt from Chapter 8.1 stormwater compliance unless federal law requires otherwise, but broader grading, drainage changes, common-plan disturbance, stormwater work, and drainageway obstructions may be reviewed under the stormwater, plot-plan, drainage, or easement framework.

• Floodplain Review: Review may involve special flood hazard areas, floodways, watercourses, drainage ditches, and drainage facilities when fence-related work qualifies as development, excavation, grading, filling, obstruction, or other regulated activity.

• Animal-Enclosure Review: Review may involve residential chicken enclosures, private-stable fencing, or dangerous-dog enclosures where those separate animal-control or use-specific standards apply.
