FENCE RULES – ERLANGER (CITY), KENTUCKY
OVERVIEW
Residential fences are permitted on private property within City of Erlanger, subject to local regulations. For properties located outside City of Erlanger municipal limits, Kenton County regulates fences in unincorporated areas.
Local fence rules appear primarily in the Erlanger Zoning Ordinance, especially Section 7.06, Fences and Walls, with related provisions in the Erlanger Code of Ordinances, Planning and Development Services of Kenton County zoning and building administration materials, clear-sight-distance standards, pool and spa standards, floodplain materials, and City street-cut or encroachment procedures.
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 the Erlanger Zoning Ordinance, Erlanger Code of Ordinances Chapter 98 and Chapter 150, Planning and Development Services of Kenton County building, zoning, code-enforcement, floodplain, and jurisdictional-services materials, and City of Erlanger Building/Zoning and Street Cut and Encroachment materials as of June 2026.
GOVERNANCE
The City of Erlanger adopts the zoning ordinance and code provisions that govern fences within city limits. The Erlanger Zoning Ordinance regulates land, structures, yards, development standards, fence and wall types, clear-sight areas, and related site standards.
The City of Erlanger does not publish a single standalone residential fence code. Residential fence rules are distributed across the zoning ordinance, city code provisions for invisible fences and permits, PDS zoning and building administration materials, floodplain materials, and public-works encroachment procedures.
Planning and Development Services of Kenton County administers zoning permits and zoning-code enforcement for Erlanger through its One Stop Shop and zoning/code-enforcement functions. PDS building-code administration materials also provide the building-permit exemption framework and identify fence projects as zoning-only permit work.
The City of Erlanger City Clerk administers the City Code permit requirement for invisible fences. City of Erlanger Public Works handles review and inspection when work involves excavating, digging, or cutting into city-owned streets or property.
PERMIT AND APPROVAL REQUIREMENTS
• Zoning Permit Required: A zoning permit is required before fence work. The Erlanger Zoning Ordinance lists fences, driveways, and decks among activities requiring a zoning permit, and PDS identifies fence permits as zoning-only permits for processing purposes.
• Building Permit Context: PDS lists fences not over 7 feet high as exempt from obtaining a building permit. The 7-foot figure is a building-permit exemption threshold, not a local maximum fence height and not a substitute for zoning approval.
• Taller Fences and Walls: Section 7.06 states that, in addition to a zoning permit, certain walls and fences may also require a building permit. The City fee schedule also distinguishes residential fences 6 feet or less from residential fences over 6 feet for fee purposes.
• Invisible Fence Permit: Invisible fences require a permit issued by the City Clerk. The City Code also regulates invisible-fence location and signage.
• Pool and Spa Barriers: Pools, spas, and related equipment are permitted only in the rear yard and may not be located within any required setback. Fences or enclosures used for pools and spas must meet the enclosure and gate requirements of the Kentucky Building Code.
• Floodplain Review: Fence work that involves construction activity in a designated floodplain may require state and local floodplain review before construction. PDS floodplain materials identify City of Erlanger separately for local floodplain-coordinator contact.
• Street Cut and Encroachment Review: Before excavating, digging, or cutting into city-owned streets or property, a City of Erlanger street-cut application is required and the work is subject to Public Works review and inspection.
FENCE PLACEMENT RULES
• Property Lines and Setbacks: The ordinance treats walls and perimeter fencing as permitted setback encroachments when regulated by Section 7.06, Fences and Walls. 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.
• Standard Residential Fence Locations: In the standard residential districts, ordinary residential fence placement is clearest in side-yard and rear-yard locations. The code does not specify a separate permitted front-yard height for ordinary residential fence types in those standard residential districts.
• Side and Rear Yards: In standard residential districts, ornamental metal, woven wire including chain link, wood or wood-like fences more than 50% open, and wood or wood-like fences less than 50% open may be used in side and rear yards, subject to the 6-foot residential height limit.
• Corner Lots and Double-Frontage Lots: Corner lots and double-frontage lots are restricted to front-yard fence regulations within any front-yard area adjacent to a street. Side-yard fences are permitted in all other yard areas. For corner lots, rear-yard fences are permitted only within rear-yard areas as defined by the ordinance.
• Corner-Lot and Double-Frontage Setbacks: On corner lots, fences must be set back one-half of the minimum required front-yard setback from the right-of-way along the side yard. On double-frontage lots, fences must be set back the minimum required front-yard setback from the right-of-way along the rear yard.
• Flag Lots: The stem portion of a flag lot is restricted to front-yard fence regulations. Other portions of the lot may have front-yard, side-yard, or rear-yard fences unless a more restrictive fence type or height is required along an adjacent lot line.
• Vacant Lots: A fence may be built on a vacant property only when a principal structure or principal use with the same ownership abuts the vacant property without a street or alley separating them. The fence must comply with Section 7.06, the material must be consistent around the property, and chain-link fences are prohibited on vacant properties in Residential and Commercial Districts.
• Planned Unit Development Lots: In a Planned Unit Development (PUD), the type, location, and height of fences and walls are controlled by the approved Concept Development Plan, Final Development Plan, or applicable PUD approval.
• Sight Triangles: Fences, walls, hedges, and other obstructions may not exceed 36 inches / 3 feet within required sight triangles.
• Invisible Fences: Invisible fences must be located at least 15 feet from any public right-of-way and no more than 15 feet in front of any principal building. A required warning sign must be posted on the property.
• Retaining Walls and Combined Walls: Retaining walls over 6 feet must be terraced or offset. A combined retaining wall and fence may be used, but the fence portion must meet the fence type and height allowed for the zoning district.
• City-Owned Streets or Property: Fence work that involves digging, cutting, or excavation in city-owned streets or property is subject to the City’s street-cut and encroachment process.
• Utility Safety: Kentucky law requires notice through Kentucky 811 before excavation where Kentucky’s underground utility damage-prevention law applies. For fence projects that involve digging, including fence post holes, notice must be given not less than two full working days and not more than 10 full working days before excavation begins, unless a different future start date is allowed by law. Kentucky locate requests are valid for 21 calendar days from the initial request. Kentucky law also includes exemptions, including certain agricultural tilling and certain nonmechanized excavation on private property where no operator right-of-way or easement is encroached.
FENCE HEIGHT AND VISIBILITY RULES
• Standard Residential Side and Rear Fences: In the standard residential districts — R-LLS, R-CVS, R-CPS, R-M, R-MF, and MHP — ordinary side-yard and rear-yard fences may be up to 6 feet high.
• Ordinary Residential Fence Types: The 6-foot side/rear residential height applies to ornamental metal, woven wire including chain link, wood or wood-like fences more than 50% open, and wood or wood-like fences less than 50% open.
• Front-Yard Height: The code does not specify a permitted front-yard height for ordinary residential fence types in the standard residential districts. A front-yard or street-adjacent fence location must be reviewed under the ordinance’s front-yard, corner-lot, double-frontage-lot, flag-lot, and sight-triangle rules.
• Corner-Lot and Double-Frontage Limits: On corner lots, fences must be set back one-half of the required front-yard setback from the right-of-way along the side yard. On double-frontage lots, fences must be set back the full required front-yard setback from the right-of-way along the rear yard.
• Street-Side Corner-Lot Limit for Wood-Type Fences: Wood or wood-like fences that are more than 50% open and wood or wood-like fences that are less than 50% open are not permitted along the street side yard of a corner lot. They are permitted in the rear on double-frontage lots.
• Sight-Triangle Height: A fence, wall, hedge, or other obstruction within a required sight triangle may not exceed 36 inches / 3 feet in height.
• Sight-Triangle Dimensions: Local street or driveway intersections with a local street use a 10-foot by 10-foot sight triangle. Local street or driveway intersections with a collector or arterial street use a 10-foot by 50-foot sight triangle. Collector or arterial street intersections use a 50-foot by 50-foot sight triangle. Street intersections with a railroad right-of-way use a 10-foot by 50-foot sight triangle.
• Sports Fences: Sports fences are separate from ordinary yard fences. Where allowed, sports fences may be up to 8 feet high, and fences up to 12 feet are permitted to enclose tennis courts or serve as baseball or softball backstops.
• Flood Retaining Walls: Flood retaining walls are governed by engineering requirements rather than a fixed zoning height.
• Planned Unit Development Height: In a Planned Unit Development (PUD), fence and wall height is controlled by the approved Concept Development Plan, Final Development Plan, or applicable PUD approval.
• Fence Height Measurement: Fence and wall height is measured from ground level where the fence or wall meets the ground to the highest point of the fence or wall. Fence-post finials may extend up to 8 inches above the maximum permitted fence height.
• Retaining Wall Measurement: For a combined retaining wall and fence, the retaining wall may extend to the highest finished grade, and the fence height is measured from the highest grade.
• Building-Permit Threshold: The 7-foot figure in the PDS building-permit materials is a building-permit exemption threshold for fences not over 7 feet. It is not a local fence-height maximum and does not replace Erlanger’s zoning height limits.
MATERIAL AND CONSTRUCTION LIMITS
• Ordinary Residential Materials: In the standard residential districts, the ordinance allows ornamental metal, woven wire including chain link, wood or wood-like fences more than 50% open, and wood or wood-like fences less than 50% open for ordinary side-yard and rear-yard residential fencing.
• Wood-Like Materials: Wood-like materials include materials designed to resemble wood, such as composite or vinyl.
• Masonry Walls: Masonry walls are described as brick, concrete block, stone, or a combination of those materials. Unfinished concrete block may not be used as a facing material. The current residential fence rules do not list masonry walls as an ordinary standard residential fence type.
• Hedge Fences and Mixed-Material Fences: Hedge fences and mixed-material fences are described in the ordinance, but they are not listed as ordinary standard residential fence types in the standard residential districts.
• Flood Retaining Walls: Flood retaining walls are listed as allowed in residential districts and are subject to engineering requirements.
• Finished Side: Fences and walls must be constructed so that the finished side faces the exterior of the property.
• Maintenance: Fences and walls must be maintained in good order and must be erected and maintained in a safe manner.
• Signs and Lettering: Fences may not contain advertising, signs, logos, or other lettering unless the sign regulations allow it.
• Required Screening: Where a fence or wall is used as part of required screening, required vegetation must be planted on the exterior side of the fence or wall. Walls and fences used for landscaping or screening must be opaque and constructed of masonry, stone, wood, vinyl, or a material similar in composition and appearance to the principal building.
• Prohibited Materials: Fences or walls topped with or containing broken glass or similar material are prohibited. Fences constructed of readily flammable material, such as paper, cloth, or canvas, are prohibited; traditional wood fences are excluded from that prohibition.
• Unlisted Materials: Fence materials not described in the ordinance are not permitted unless the Zoning Administrator approves the material as a like-material that meets or exceeds the intent of the fence standards.
• Barbed Wire and Electric Fencing: Barbed wire and electric fencing are permitted only in the Agriculture district where accessory to a permitted agricultural use. They are not ordinary residential fence materials under Erlanger’s residential fence rules.
• Chain Link on Vacant Lots: Chain-link fences are prohibited on vacant properties in Residential and Commercial Districts.
• Pool Enclosures: A fence used as a pool or spa barrier must meet the enclosure and gate requirements of the Kentucky Building Code.
PRIVATE RESTRICTIONS
HOAs, subdivision covenants, deed restrictions, private easements, architectural-review covenants, private boundary agreements, and other private restrictions operate independently from City zoning rules and may be more restrictive.
The Erlanger Zoning Ordinance states that private agreements such as deed restrictions or covenants are not enforced by the City unless the City is directly a party in interest. Private restrictions may still affect whether a fence is allowed on a specific property.
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 Review: Fence work is reviewed through the zoning-permit process for compliance with the Erlanger Zoning Ordinance.
• Building Review: Certain walls and fences may also require building review, while PDS lists fences not over 7 feet as exempt from obtaining a building permit.
• Side and Rear Fence Height: Ordinary residential side-yard and rear-yard fences in the standard residential districts are reviewed against the 6-foot residential height limit.
• Front-Yard and Street-Adjacent Locations: Because the code does not specify a permitted front-yard height for ordinary residential fence types in the standard residential districts, front-yard and street-adjacent fence locations are reviewed through the ordinance’s front-yard, corner-lot, double-frontage-lot, flag-lot, and sight-triangle rules.
• Corner Lots and Double-Frontage Lots: Review may include whether a fence is in a street-adjacent front-yard area, whether the required right-of-way setback applies, and whether wood-type fences are barred along the street side yard of a corner lot.
• Clear-Sight Areas: Fences, walls, hedges, or other obstructions over 36 inches / 3 feet in required sight triangles may create a zoning compliance issue.
• Materials and Finished Side: Review may include prohibited materials, unlisted materials, finished-side orientation, and whether the fence is maintained in good and safe condition.
• Vacant Lots: Fences on vacant lots are reviewed for the same-ownership abutting-property rule, material consistency, and the chain-link prohibition.
• Invisible Fences: Invisible fences may be reviewed for the required City Clerk permit, right-of-way distance, front-of-building distance, and signage.
• Pool Barriers: Fences used as pool or spa barriers may be reviewed under pool, enclosure, gate, and building-code requirements.
• Floodplain and Right-of-Way Conditions: Fence work in a designated floodplain or involving city-owned streets or property may require separate floodplain, street-cut, or encroachment review.
