FENCE RULES – ALEXANDRIA (CITY), VIRGINIA

OVERVIEW

Residential fences are permitted on private property within City of Alexandria, subject to local regulations.

For properties located outside City of Alexandria city limits, fence rules depend on the applicable county, town, city, or governing authority for the property location.

Local fence rules appear principally in the City of Alexandria Zoning Ordinance, including Section 7-202, Section 7-800, and Section 7-1700. Related requirements also appear in the City Code provisions for streets, sidewalks, encroachments, erosion and sediment control, the Environmental Management Ordinance in Article XIII of the Zoning Ordinance, City permit materials, Transportation & Environmental Services permit guidance, and Historic Preservation / Board of Architectural Review 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.

Compiled From City of Alexandria Zoning Ordinance, City of Alexandria Code of Ordinances, Permit Requirements, Land Use and Zoning materials, Virginia Erosion and Stormwater Management Program materials, Transportation & Environmental Services permit guidance, Right-of-Way Administrative Encroachment Permit materials, Historic Preservation materials, Old and Historic Alexandria District Fences, Gates + Walls guidelines, Parker-Gray District Fences, Gates + Walls guidelines, and Virginia statewide fence-law baseline materials as of July 2026.

GOVERNANCE

The City of Alexandria regulates residential fences through multiple sources rather than one consolidated fence code. The core zoning rules are in the Zoning Ordinance provisions for permitted obstructions in required yards, vision clearance, and fences on corner and through lots.

The Land Use Services Division of the Department of Planning & Zoning administers zoning questions for fences and directs property owners to the Zoning Planner of the Day for fence and shed zoning issues. The Department of Code Administration administers local building-permit review through the City permit system.

Transportation & Environmental Services administers right-of-way, encroachment, excavation, erosion and sediment control, stormwater, and Chesapeake Bay / Environmental Management review where those site conditions apply. Historic Preservation staff and the Board of Architectural Review administer fence, wall, gate, and exterior-work review in the Old and Historic Alexandria District, the Parker-Gray District, and other locally regulated historic contexts described in City materials.

PERMIT AND APPROVAL REQUIREMENTS

• Building Permit: City permit materials identify fences greater than 6 feet in height as a residential permit category. A fence that does not require a building permit must still comply with the Zoning Ordinance.

• Zoning Compliance: Fences must comply with Zoning Ordinance Section 7-202, Section 7-800, and, for corner and through lots, Section 7-1700. City Land Use and Zoning materials direct fence questions to the Zoning Planner of the Day through the Land Use Services Division of the Department of Planning & Zoning.

• Historic District / BAR Approval: Board of Architectural Review approval is required for fences in local historic districts. The Old and Historic Alexandria District and Parker-Gray District guidelines identify administrative staff review for construction or modification of fences, gates, garden walls, and retaining walls, and Board review for demolition of masonry walls of 25 square feet or more.

• Right-of-Way / Encroachment Approval: Encroachments into a public street, alley, sidewalk, or other public right-of-way require authorization under the City Code and right-of-way permit process. The Code specifically identifies Parker-Gray Historic District front fences that otherwise meet permitted front-yard height and location standards as eligible to be constructed in the public right-of-way through the encroachment framework.

• Erosion, Stormwater, and Chesapeake Bay Review: The City administers erosion and sediment control, VESMP, and Environmental Management requirements through Transportation & Environmental Services. City materials state that construction projects disturbing at least 2,500 square feet require a City-approved construction pollution prevention plan and site runoff controls. The Zoning Ordinance designates all land within the City as a Chesapeake Bay Preservation Area, divided into Resource Protection Areas and Resource Management Areas. Installation of fence posts is listed as an erosion-and-sediment-control exception, but that narrow exception does not remove review for larger clearing, grading, fill, Resource Protection Area work, shoreline work, wetland impacts, or other regulated land-disturbing activity.

• Pool Barrier: A fence used as a barrier for a private swimming pool, spa, or hot tub is reviewed as part of pool-barrier and building-code compliance and is not treated as an ordinary non-pool yard fence.

FENCE PLACEMENT RULES

• 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.

• Survey / Plat Context: Historic district fence and wall guidelines state that a survey plat may be required to ensure that a fence, gate, or wall is located on the applicant’s property.

• All Required Yards: Open fences not exceeding 4 feet in height are permitted in all required yards. An open fence is a fence whose surface is at least 50 percent uncovered.

• Side and Rear Yards: Open and closed fences not exceeding 6 feet in height are permitted in any yard except a front yard.

• Residential Lots Abutting Nonresidential Uses: Open and closed fences not exceeding 10 feet in height are permitted in required side or rear yards on a residential lot when that yard abuts a lot developed with a nonresidential use.

• Abutting Dwelling Openings: Outside the Old and Historic Alexandria and Parker-Gray Districts, fences exceeding 4 feet in height must be located at least 5 feet from a shared lot line along and beyond qualifying lower sill or threshold openings on an abutting principal dwelling, when those openings face the shared lot line and are within 3 feet of it.

• Corner Lots: On corner lots, open and closed fences not exceeding 6 feet in height are allowed in required secondary front yards only when they are behind the front building wall facing the primary front yard and meet the secondary-front-lot-line setback method in Section 7-1700.

• Through Lots: On through lots, open and closed fences not exceeding 6 feet in height must meet the Section 7-1700 secondary-front-yard setback method. Where abutting principal structures on the same side of the street face that street, the fence may be no closer than half the distance between the secondary front lot line and the average setback using the two abutting properties; otherwise, or where there are no abutting houses, the fence must be at least 3 feet from the secondary front lot line.

• Right-of-Way: A fence must not encroach into a public street, alley, sidewalk, or other public right-of-way unless authorized through the City’s right-of-way or encroachment process. Barbed-wire fences are prohibited adjacent to any street, public alley, or court line within the City.

• Stormwater / Chesapeake Bay Context: Ordinary fence-post installation is listed as an erosion-and-sediment-control exception, but broader fence-related work involving clearing, grading, fill, land disturbance, Resource Protection Areas, Resource Management Areas, tidal wetlands, tidal shores, nontidal wetlands connected by surface flow, perennial-flow waters, or the 100-foot RPA buffer may require separate review under the City’s Environmental Management, erosion, stormwater, or shoreline-related requirements.

• 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 Yards: Open fences are permitted in required front yards when they do not exceed 4 feet in height.

• Side and Rear Yards: Open and closed fences are permitted in side and rear yards when they do not exceed 6 feet in height.

• Residential Lots Next to Nonresidential Uses: Open and closed fences up to 10 feet in height are permitted in required side or rear yards on a residential lot when the yard abuts a lot developed with a nonresidential use.

• Corner and Through Lots: Open and closed fences up to 6 feet in height are permitted in required secondary front yards only when the Section 7-1700 placement standards and the Section 7-800 vision-clearance rules are met.

• Vision Clearance: Within the area enclosed by a diagonal line connecting two points located 30 feet from the intersecting curb line, the Zoning Ordinance prohibits fences, structures, shrubbery, or other obstructions to vision more than 4 feet above curb grade. A tree trunk is excepted, but branches or foliage less than 8 feet above grade are not.

• Historic District Waiver: In the Old and Historic Alexandria District and the Parker-Gray District, the Board of Architectural Review may waive or modify the front-yard and side/rear-yard fence requirements when it finds that the proposed fence would be architecturally appropriate and consistent with the character of the district. The Board may also waive Section 7-800 vision-clearance requirements where doing so is consistent with historic character.

• Permit Trigger Context: The City permit materials identify fences greater than 6 feet in height as a residential permit category. That permit trigger is separate from the zoning height limits that determine where and when a fence may be placed.

MATERIAL AND CONSTRUCTION LIMITS

• Standard Residential Materials: Outside the specific historic-district and barbed-wire rules stated below, the code does not publish a comprehensive material list, finished-side rule, or fence-orientation rule for standard residential fences in the referenced published materials.

• Open Fence Standard: An open fence must have at least 50 percent of its surface uncovered.

• Historic District Materials: Old and Historic Alexandria District and Parker-Gray District guidelines state that fences, gates, and walls must be architecturally appropriate to the structure and may be made of wood, metal, or masonry. The guidelines state that the Board discourages poured-in-place concrete and synthetic materials such as fiberglass or vinyl.

• Historic District Design: The historic district guidelines identify iron and other metal fences as appropriate for late nineteenth- and early twentieth-century Victorian structures and state that wood fences must have vertical pickets.

• Barbed Wire: The City Code prohibits construction or maintenance of a barbed-wire fence adjacent to any street, public alley, or court line within the City.

• Trellises Attached to Fences: A trellis attached to a fence must comply with Section 7-202 and Section 7-1700. A trellis that exceeds 6 feet in height and 15 feet in length must also comply with those sections.

• Pool Barriers: Fences used as swimming-pool, spa, or hot-tub barriers must meet the applicable pool-barrier rules and inspections for that pool installation.

PRIVATE RESTRICTIONS

Private restrictions operate independently from City zoning, building, historic, right-of-way, stormwater, Chesapeake Bay, and utility-safety rules. HOAs, condominium associations, covenants, subdivision restrictions, deed restrictions, private easements, architectural-review covenants, conservation easements, and private boundary agreements may impose standards that are more restrictive than the City’s published rules.

City approval of a building permit, zoning-compliant placement, Board of Architectural Review approval, right-of-way encroachment permit, or stormwater-related review does not override private restrictions unless the private instrument itself provides otherwise.

REVIEW AND ENFORCEMENT CONTEXT

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

• Building Permit Review: Fences greater than 6 feet in height are identified as a residential permit category in City permit materials.

• Zoning Review: Section 7-202 controls permitted fence obstructions in required yards, Section 7-800 controls vision clearance, and Section 7-1700 controls qualifying fences on corner and through lots.

• Historic Review: Fences in the Old and Historic Alexandria District and Parker-Gray District may require Historic Preservation staff or Board of Architectural Review approval depending on the proposed work and review category.

• Right-of-Way Review: Encroachments into public streets, alleys, sidewalks, or other public rights-of-way are reviewed through the City Code and Transportation & Environmental Services permit framework.

• Stormwater and Chesapeake Bay Review: Fence-related work can trigger erosion, stormwater, VESMP, Chesapeake Bay Preservation Area, Resource Protection Area, or Resource Management Area review when it involves regulated land disturbance, clearing, grading, fill, shoreline or wetland conditions, or work beyond ordinary fence-post installation.

• Visibility and Safety: Review may involve the 30-foot vision-clearance triangle, the 4-foot obstruction limit within that triangle, barbed-wire restrictions along streets, alleys, and court lines, Virginia 811 utility safety, and pool-barrier requirements when the fence is part of a pool enclosure.
