FENCE RULES – FLORENCE (CITY), KENTUCKY

OVERVIEW

Residential fences are permitted on private property within City of Florence, subject to local regulations. For properties located outside City of Florence municipal limits, Boone County regulates fences in unincorporated areas.

Local fence rules appear primarily in the Boone County Zoning Regulations, including Section 3153, Location of Accessory Structures or Uses, Section 3655, Fences, Article 23, Florence Main Street Zoning Study, and related zoning-permit, visibility, floodplain, historic, and right-of-way provisions. City-specific rules also appear in the City of Florence Code of Ordinances, including Chapter 151, Building Regulations, Chapter 155, Flood Damage Prevention, and the City’s code-enforcement provisions.

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 Boone County Zoning Regulations, City of Florence Code of Ordinances, Boone County Planning Commission Zoning Permit Application – Accessory Structures, Boone County Encroachment Permit Application, and Kentucky statewide residential-code and utility-notice baseline rules as of June 2026.

GOVERNANCE

The City of Florence participates in the Boone County Planning Commission county-wide planning unit. The Boone County Zoning Regulations apply within the City of Florence and are administered through the Zoning Administrator, the Boone County Planning Commission, and the applicable City legislative and enforcement structure.

The City of Florence does not publish a single stand-alone residential fence code. Fence rules are distributed across the Boone County Zoning Regulations, the City of Florence Code of Ordinances, the zoning permit process, the Florence Main Street district standards, floodplain rules, historic-overlay review, right-of-way and encroachment materials, and code-enforcement provisions.

The City of Florence Code of Ordinances establishes a Code Enforcement Board with jurisdiction over City ordinances and zoning or nuisance provisions that are subject to civil enforcement. The zoning regulations also provide for complaint investigation and zoning-enforcement review through the Zoning Administrator or Zoning Enforcement Officer.

PERMIT AND APPROVAL REQUIREMENTS

• Zoning Permit: A zoning permit is the local zoning approval path for residential fences. The Boone County Zoning Regulations require zoning permits for accessory structures, and Section 3153 treats fences as accessory structures for fence-location rules. The published Boone County Planning Commission zoning-permit application for accessory structures applies to the City of Florence jurisdiction.

• Zoning Permit Sequence: The Boone County Planning Commission zoning-permit application states that a zoning permit must be issued before a building permit can be granted. Where a building permit is also involved, zoning approval comes first.

• Building Permit Baseline: Under the Kentucky Residential Code building-permit baseline, fences not over 7 feet high are exempt from a building permit. City of Florence does not publish a stricter local residential fence building-permit threshold or an all-fences building-permit rule in the official source materials reviewed for this page. Standard residential fences in City of Florence residential districts are limited by zoning to 6 feet, so the ordinary residential fence height listed in Section 3655 falls within that building-permit exemption.

• Retaining Walls: Retaining walls are handled separately from ordinary fences. A proposed retaining wall 4 feet or less that does not change overall grading or drainage, is not a substantive structural component of a grade, and would not cause property damage if it fails is handled through a Zoning Permit or Minor Site Plan application, as applicable. A retaining wall over 4 feet, a wall that changes grading or drainage, a wall that is a substantive structural grade component, or a wall that could cause property damage if it fails requires a Major Site Plan or Grading Plan application, as applicable.

• Florence Main Street District: Properties in the Florence Main Street (FMS) District are subject to Article 23 fence modifications in addition to Section 3655. FMS fences must meet Section 3655 except where Article 23 modifies those standards.

• Historic Overlay / Historic Landmark: In a Historic Overlay District or at a Historic Landmark site, a Certificate of Appropriateness is required before alterations or additions to a building, structure, or site. The code does not publish a separate fence-only historic standard outside that COA framework.

• Floodplain and Stream Review: A development permit is required before development activities in Special Flood Hazard Areas. The Boone County zoning-permit form also requires flood-level information where applicable and requires a Stream Construction Permit from the Water Resources Branch of the Kentucky EPA or approval from the Local Floodplain Coordinator if any portion of the lot or parcel is within a designated 100-year floodplain or near a blue-line stream with a tributary area of one square mile or greater and no designated flood elevations.

• Right-of-Way / Encroachment: No fence may be located within a public right-of-way. Work under or over Boone County roads and highways is handled through the Boone County Public Works Department Encroachment Permit Application. If a project adds a curb cut, the zoning-permit application requires an approved encroachment permit; for City of Florence locations, the form directs the applicant to City of Florence review, and for state roads it directs the applicant to the Kentucky Transportation Cabinet permit process.

FENCE PLACEMENT RULES

• Standard Residential Location: In residential districts and the GR-R district, fences are required to be located in the side or rear yards, except where a more specific City of Florence rule allows a corner-side-yard or FMS placement.

• Front Yards: The standard Florence residential rule does not create a citywide front-yard fence allowance. Front-yard fences are addressed only where a specific rule applies, such as the Florence Main Street District front-yard fence standard.

• Corner Side Yards: In the City of Florence, fences are permitted in the corner side yard only under the Florence-specific standards in Section 3655. The maximum height is 4 feet, the fence must be decorative, the opacity must be 50% or less, and utilitarian styles are prohibited.

• Florence Main Street District: In the FMS District, fences and walls 42 inches or less are permitted in front yards. Fences and walls higher than 42 inches are permitted for an enclosed courtyard. Article 23 does not state a separate numeric maximum for enclosed-courtyard fences or walls; for typical residential use, the Section 3655 residential maximum remains 6 feet unless another approved zoning condition applies.

• 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.

• Accessory-Structure Setback: The general 5-foot accessory-structure setback does not apply to fences located in side or rear yards. Fence placement is controlled by Section 3655 and the applicable yard, right-of-way, visibility, floodplain, historic, and site conditions.

• Right-of-Way and Sight Triangle: No fence may be located in a public right-of-way, and no fence may be located where it obstructs the sight triangle for a motorist or pedestrian as defined through the zoning regulations’ Article 32 visibility framework.

• Plot Plan Conditions: The zoning-permit application requires the plot plan to show lot lines, street centerlines, right-of-way lines, adjoining residences where applicable, historic landmarks or districts, streams or rivers where applicable, existing and proposed structures, setbacks, utility poles and boxes, and existing or proposed easements.

• 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

• Residential Districts: The maximum fence height in residential districts and the GR-R district is 6 feet.

• Side and Rear Yards: Standard residential fences located in permitted side and rear yards are subject to the 6-foot residential maximum.

• Corner Side Yard – City of Florence: A Florence corner-side-yard fence may be up to 4 feet high and must meet the Florence-specific decorative-design and opacity standards.

• Florence Main Street Front Yard: In the FMS District, front-yard fences and walls may be up to 42 inches high.

• Florence Main Street Courtyard: In the FMS District, fences and walls higher than 42 inches are permitted for an enclosed courtyard. Article 23 does not publish a separate numeric maximum for enclosed-courtyard fences or walls; for typical residential use, the Section 3655 6-foot residential maximum remains the residential fence-height reference.

• Visibility: No fence may obstruct the sight triangle for any motorist or pedestrian. Intersection sight-distance determinations are handled under Article 32 by the applicable roadway authority, including the Kentucky Transportation Cabinet, County Engineer, or City Engineer depending on the roadway.

• Building-Permit Threshold: The 7-foot Kentucky Residential Code figure is a building-permit exemption threshold. It is not a local maximum fence height, and it does not replace the City of Florence zoning height limits.

MATERIAL AND CONSTRUCTION LIMITS

• Finished Side: All fences must have the finished side facing out. Structural supports may not be visible from adjoining properties or rights-of-way unless the fence is designed so that supports are visible from both sides.

• Durability and Maintenance: All fences must be constructed of durable materials, installed to withstand the elements, and maintained in good repair.

• Residential Prohibited Materials: Barbed wire, stock wire, chicken wire, electric fences, and similar fences are not permitted for residential uses in residential districts.

• City Barbed-Wire Rule: The City of Florence Code of Ordinances prohibits barbed wire fencing on all property used for residential purposes and on all property located within a residential zone.

• Corner Side Yard Materials: In a City of Florence corner side yard, fences must be decorative, such as wrought iron, architectural steel, picket, wood or vinyl picket, or post and rail. The fence must have opacity of 50% or less. Chain link with or without vinyl coating, barbed wire, stock wire, chicken wire, chains on posts, and similar utilitarian styles are not permitted in this location.

• Florence Main Street Materials: In the FMS District, fences must be compatible with the design and material of the building and block. Cast iron, dark architectural steel, or milled wood picket-style fences are identified as most appropriate in front yards. Chain link, plastic, PVC, split rail, rustic wood, unmilled dimensional lumber, and similar materials are prohibited. FMS fences must have opacity of 50% or less.

• Ordinary Side and Rear Chain Link: Section 3655 does not list standard chain link as a prohibited material for ordinary residential side-yard or rear-yard fences. Chain link is prohibited in Florence corner-side-yard fences and in the FMS District fence standards described above.

• Agricultural Fences: Fences for agricultural purposes are exempt from Section 3655. That exemption is an agricultural-purpose rule and does not replace the standards for ordinary residential yard fencing.

PRIVATE RESTRICTIONS

HOAs, subdivision covenants, deed restrictions, private easements, architectural-review covenants, recorded private agreements, agricultural agreements, and other private restrictions operate independently from City of Florence zoning and Boone County Planning Commission review.

A fence that satisfies the public zoning rules may still be limited by a private restriction. The City of Florence materials reviewed for this page do not state that the City enforces private HOA or covenant restrictions as part of ordinary residential fence approval.

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 location, height, materials, right-of-way location, sight-triangle impacts, easements, floodplain status, historic-overlay status, and FMS district standards may be reviewed through the zoning-permit process.

• Building-Permit Exemption Context: Fences not over 7 feet are exempt from a building permit under the Kentucky Residential Code baseline, but that exemption does not remove local zoning-permit, height, placement, visibility, floodplain, historic, right-of-way, or private-restriction requirements.

• Height and Yard Location: Residential fences are reviewed against the 6-foot residential maximum, the side/rear yard placement rule, the Florence corner-side-yard standards, and the FMS front-yard or courtyard standards where applicable.

• Visibility and Right-of-Way: Fences are reviewed for public right-of-way encroachment and sight-triangle obstruction. Encroachment work under or over Boone County roads and highways is handled through the Boone County Public Works encroachment permit process, and state-road work is handled through the Kentucky Transportation Cabinet where applicable.

• Materials: Finished-side orientation, durable construction, maintenance, barbed-wire limits, electric-fence limits, corner-side-yard decorative requirements, and FMS material prohibitions are review points where applicable.

• Floodplain and Stream Conditions: Fence or wall work that is part of development activity in a Special Flood Hazard Area, designated 100-year floodplain, or blue-line stream context may require floodplain or stream approval before work begins.

• Historic Overlay Conditions: Work in a Historic Overlay District or at a Historic Landmark site may require a Certificate of Appropriateness when it is an alteration or addition to a building, structure, or site.

• Complaint-Based Enforcement: The City of Florence code-enforcement structure and the Boone County Zoning Regulations provide mechanisms for investigation and enforcement when a fence is alleged to violate zoning, right-of-way, material, location, maintenance, or approval requirements.
