FENCE RULES – GRETNA (CITY), LOUISIANA
OVERVIEW
Residential fences are permitted on private property within City of Gretna, subject to local regulations.
The principal residential fence standards for City of Gretna appear in Division 8, Fencing and Screening, of the Unified Development Code. Related permit administration appears on the Building Department page and in Chapter 10 of the City of Gretna Code of Ordinances. Separate historic-district fence approval rules appear in Chapter 52 and on the Historic District Commission page.
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.
The City’s published permit guidance states that all new and replacement fences must be permitted, and the Building Department states that fencing of any size requires a building permit. Within the historic districts, exterior fence work visible from public right-of-way is also subject to Historic District Commission review.
Compiled From the Unified Development Code, Chapter 10 and Chapter 52 of the City of Gretna Code of Ordinances, the Building Department page, the Historic District Commission page, the Planning and City Development page, the Permitting page, and the City of Gretna Fence Factsheet as of March 2026.
GOVERNANCE
Residential fence administration in the City of Gretna is split among the Building Department, the Department of Planning and City Development, and, where historic-district review applies, the Historic District Commission.
The controlling dimensional and design standards for standard residential fences appear primarily in the Unified Development Code, especially Sec. 58-261 Fence Regulations and the related Sec. 58-222 Clear Vision Areas. General building-permit administration appears in Chapter 10 of the City Code. Historic-district approval requirements appear in Chapter 52 Historic Preservation and the Historic District Commission materials.
The City does not publish all residential fence rules in a single standalone ordinance section. Permit policy is stated on the Building Department page and the City’s Fence Factsheet, while height, placement, and material controls appear in the Unified Development Code and historic-district materials.
PERMIT AND APPROVAL REQUIREMENTS
• Building Permit: The Building Department states that fencing of any size requires a building permit, and required permit(s) must be obtained before any work is begun.
• No Published Height-Based Permit Exemption: The City’s published materials do not state a local permit exemption for standard residential fences under a stated height threshold. The stated policy is that fencing of any size and all new and replacement fences must be permitted.
• Residential Permit Fee: The City’s Fence Factsheet states that residential fence permits are free.
• Zoning Compliance: Building permit requirements are separate from zoning, setback, or plat requirements. Confirm any applicable zoning conditions, setbacks, and plat requirements with Department of Planning and City Development before construction.
• Application Materials: The City’s published fence guidance calls for identification of the property’s zoning district and historic-district status, a site plan showing the fence location, all structures, proposed fence height, and proposed fence material, and a signed fence affidavit.
• Stamped Drawings: The City’s published fence guidance states that stamped drawings are required for fences over 8 feet and for chain walls with an above-ground height over 12 inches, which are treated as retaining walls.
• Historic District Review: Within Gretna’s historic districts, exterior work visible from public right-of-way must receive a Certificate of Appropriateness from the Historic District Commission. The historic-preservation ordinance specifically includes fences and boundary walls, and requires review for changes to or construction of walls and fences along a public street.
FENCE PLACEMENT RULES
• Lot-Line Placement: The Unified Development Code allows residential lot fencing along lot lines and does not state a separate side-yard or rear-yard setback requirement for standard residential fences.
• Side Yard Limit: A side yard fence may not extend in front of the front corners of any residence.
• Corner Lots: On corner lots, a side-yard or rear-yard fence facing a side street must satisfy at least one of these conditions: it must be set back at least the same distance as the front building line of the primary structure on the adjacent lot facing the side street, but not greater than 10 feet; or, if located within 10 feet of a side or rear property line abutting a street, it may not exceed 6 feet in height; or it must be located and designed so the zoning administrator determines it minimizes interference with view, including the clear-vision-area rules.
• Front Yard Areas: In R-1 and R-2 districts, front yard fences are allowed only in the areas identified by the Unified Development Code: on the north side of the Westbank Expressway (US 90), excluding the Old Garden Park neighborhood overlay district, and in the Jonestown neighborhood overlay district.
• Historic District Street-Facing Fences: Within the historic districts, changes to existing walls and fences, or construction of new walls and fences, along a public street require Historic District Commission review.
• Utility Safety: Louisiana’s Underground Utilities and Facilities Damage Prevention Law requires the person responsible for excavation or demolition to provide notice to the regional notification center (Louisiana 811) before digging. Notice must be provided at least two (2) full business days before the proposed commencement date of the excavation or demolition. Markings are considered valid up to 20 calendar days from the “mark-by” time, as long as the marks remain visible.
FENCE HEIGHT AND VISIBILITY RULES
• Side and Rear Yards: A side-yard or rear-yard fence or wall may not exceed 8 feet in height.
• Sloping Grade: Where a fence follows a sloping grade, height may be averaged across stepped 6-foot segments or increased by 1 inch for every 20 feet of fence length for a uniform-height fence. In either case, no portion of the fence may exceed 9 feet.
• Fence Columns: Columns in side-yard or rear-yard fences or walls, if spaced not less than 5 feet apart, may not exceed 9 feet in height.
• Front Yards: A front-yard fence or wall may not exceed 4 feet in height.
• Height Measurement: Fence height is measured from the nearest interior adjacent grade of the permit holder’s property and includes the height of any chain wall.
• Clear Vision Areas: In R-1 and R-2 districts, fences and walls may not exceed 3 feet in height within clear vision areas.
• Intersection Visibility: Within clear vision areas, there may be no obstruction between 3 feet and 8 feet in height, measured from the crown of the abutting streets. Fence columns, posts, and similar supports in the clear zone may not exceed 18 inches in width or diameter.
• Driveway Visibility: A front-yard fence or wall may not be constructed in a way that creates a traffic-safety hazard by obstructing view from a driveway to the adjoining street or vice versa.
MATERIAL AND CONSTRUCTION LIMITS
• Street-Facing Fence Materials: The Unified Development Code states that all fences facing public right-of-way must be constructed of wood, wrought metal, or cast metal, and must expose the finished side outward. The zoning administrator may allow an alternative material of similar appearance and durability.
• Published City Materials Guidance: The City’s Fence Factsheet identifies wood, brick, stucco, metal, and wrought/cast metal as allowed fencing materials.
• Chain Link: Chain-link security fencing may be established only on side and rear yards that do not face a street. The City’s published fence guidance also states that chain link or chain link plus fabric is prohibited in front yards or anywhere it can be seen from the street.
• Barbed and Razor Wire: Barbed wire and razor wire are not allowed in residential, business, or commercial districts.
• Chain Walls: A chain wall must be constructed of concrete or masonry, must be at least 6 inches wide, and may not exceed 12 inches in height above the outside adjacent grade. A higher wall is treated as a retaining wall and requires stamped design by a design professional.
• Structural Soundness: Fences must be structurally sound and durable. Paper, cloth, reeds, canes, and canvas may not be used as fence materials or as attachments or supplements to a fence.
PRIVATE RESTRICTIONS
Private covenants, subdivision restrictions, and homeowners’ association rules operate independently of City of Gretna regulations and may be more restrictive than the municipal standards summarized here.
REVIEW AND ENFORCEMENT CONTEXT
Fence issues are typically reviewed during permit or approval review when required, and through complaint-based code enforcement. Examples include:
• Permit Review: The City reviews all new and replacement fences through the permit process, including fence location, height, material, and required application documents.
• Historic District Review: Within the historic districts, the Historic District Commission reviews exterior fence work visible from public right-of-way before building-permit issuance.
• Visibility and Corner-Lot Conditions: Review may address clear-vision-area obstructions, driveway sight hazards, and corner-lot fence placement or height where a fence faces a side street.
• Material Compliance: Review may address whether a street-facing fence uses allowed materials, whether the finished side faces outward, whether chain-link is visible from the street, and whether prohibited wire materials are used.
• Construction Compliance: Review may address chain wall height, retaining-wall treatment where applicable, and whether stamped plans were required for work exceeding the published thresholds.
• Permit Conformity: The Unified Development Code authorizes permit revocation when permitted work is not in conformity with the governing article.
