FENCE RULES – MOUNT WASHINGTON (CITY), KENTUCKY

OVERVIEW

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

Local fence rules for City of Mount Washington appear across the City of Mt. Washington Code of Ordinances, the Bullitt County and Cities Zoning Regulations adopted by reference, Bullitt County Planning & Zoning permit and zoning-compliance materials, City building and code-enforcement materials, subdivision regulations, encroachment rules, stormwater and floodplain rules, pool-enclosure standards, and the Mt. Washington SmartCode where that regulating framework applies.

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 Mt. Washington Code of Ordinances, Bullitt County and Cities Zoning Regulations, Bullitt County Planning & Zoning Building Permit / Zoning Compliance materials, City of Mt. Washington Building, Housing, and Construction materials, Mt. Washington SmartCode, Bullitt County Subdivision Regulations, City encroachment, stormwater, flood damage prevention, pool-enclosure, and code-enforcement materials, and attached Bullitt County permit and code-enforcement materials, as of June 2026.

GOVERNANCE

The City of Mount Washington administers local building and code-enforcement functions through its building, housing, construction, and code-enforcement structure. City code adopts the Kentucky Building Code and Kentucky Residential Code framework, while local zoning is administered through the zoning regulations and zoning-compliance process involving Bullitt County Planning & Zoning.

The Bullitt County and Cities Zoning Regulations contain the primary citywide zoning rules for fences, walls, hedges, front-yard visibility, and residential corner-lot visibility. The City code adopts zoning regulations and the zoning map by reference.

Bullitt County Planning & Zoning is part of the practical approval structure for zoning compliance. City building materials direct applicants to obtain zoning compliance from Bullitt County Planning & Zoning before City permit review when a City permit or zoning-compliance certificate is required.

The Bullitt County Subdivision Regulations apply to subdivision plats in Bullitt County and participating cities, including Mount Washington. Those regulations are relevant where fence placement is affected by recorded plats, easements, rights-of-way, setback lines, street sight lines, drainage, utilities, floodplain marking, protective covenants, or subdivision conditions.

The Mt. Washington SmartCode applies only where property is within an approved SmartCode / Community Plan regulating area. In those areas, site design, landscape, frontage, fence, garden-wall, and streetscreen standards may be reviewed through the SmartCode process.

PERMIT AND APPROVAL REQUIREMENTS

• Bullitt County Planning & Zoning Fence Treatment: Fences less than 6 feet in height do not require a permit from Bullitt County Planning & Zoning, but they must conform to applicable easement requirements, setback requirements, and sight distances. Inspections are required for all fences greater than 7 feet in height.

• City Permit and Zoning-Compliance Workflow: For projects that require City permit review, City materials direct applicants to obtain zoning compliance from Bullitt County Planning & Zoning before City permit review. The City’s permit workflow uses the zoning-compliance certificate as part of the local building-permit review process.

• Right-of-Way and Encroachment Approval: A City encroachment permit is required before work occurs within a City right-of-way or easement, including fence construction or removal, drainage ditch modifications, or other construction or disturbance in a City right-of-way or easement.

• Road Access and Driveway Encroachments: Where a fence project is connected with driveway access or work from a City, county, or state maintained roadway, the applicable City, county road department, or Kentucky Transportation Cabinet encroachment process may apply.

• Stormwater / Land-Disturbance Review: A stormwater quality management permit is required before land-disturbing activity that disturbs one acre or more. This is not an ordinary fence permit, but it may matter for fence work that is part of a larger grading, clearing, drainage, or land-disturbance project.

• Floodplain Development Permit: A development permit is required before development activities begin in a special flood hazard area. Fence work in a mapped floodplain or flood-prone area may require review by the Floodplain Administrator when the work qualifies as development or affects fill, drainage, structures, storage of materials, or watercourse conditions.

• Swimming Pool Barrier Review: A fence used as a swimming-pool enclosure is reviewed under the pool-enclosure rules, not only as an ordinary yard fence. Pool enclosures, including gates, must meet the City’s pool-enclosure requirements.

• SmartCode / Community Plan Review: In a property subject to the Mt. Washington SmartCode, fence, garden-wall, frontage, streetscreen, and landscape standards may apply through the SmartCode review structure before permits are issued.

FENCE PLACEMENT RULES

• Required Front Yards: In a required front yard, fences and walls may not materially impede vision across the yard above 30 inches in height.

• Other Yard Locations: Except in required front yards, the zoning regulations allow fences, walls, and hedges in a yard or along the edge of a yard. The code does not specify a single citywide numerical side-yard or rear-yard fence setback for standard residential fences, but Bullitt County Planning & Zoning requires fences to conform to applicable easement, setback, and sight-distance requirements.

• Planned Unit Development Front-Yard Exception: In a Planned Unit Development with site plan review, the Planning Commission may permit fences, walls, or hedges above 30 inches in a front yard when the site and buildings are designed to accommodate enclosure, or when the fence, wall, or hedge is required as a condition of approval.

• Corner Lots and Visibility Areas: On a corner lot in a residential district, objects that materially impede vision are restricted within the required visibility area. This affects fences, walls, hedges, plantings, structures, signs, and other visual obstructions.

• Rights-of-Way and Public Ways: Fences may not obstruct a street, alley, sidewalk, or other public way. Fence construction or removal within a City right-of-way or easement requires the applicable City encroachment approval.

• Drainage and Easements: Fence placement may be limited by recorded drainage easements, utility easements, rights-of-way, subdivision plats, stormwater facilities, drainage ditches, and other recorded site constraints. The subdivision regulations require plats to show rights-of-way, easements, setback lines, property lines, utilities, drainage information, and related subdivision conditions.

• Subdivision Sight Lines: In subdivision street-intersection contexts, proper sight lines must be maintained and the clear sight triangle must remain free of shrubs, structures, signs, and other visual obstructions.

• Floodplain and Watercourse Locations: Fence work in special flood hazard areas, flood-prone areas, or areas involving watercourses, fill, drainage, or land disturbance may be subject to floodplain or stormwater review.

• 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

• Required Front Yards: In a required front yard, fences and walls may not materially impede vision across the yard above 30 inches in height.

• Other Standard Residential Yard Areas: The code does not specify a general citywide maximum fence height for standard residential fences outside required front yards. Other limits may apply through inspection thresholds, visibility rules, SmartCode standards, pool-enclosure requirements, floodplain review, easements, plats, or private restrictions.

• Bullitt County Planning & Zoning Inspection Threshold: Fences greater than 7 feet in height require inspections. Fences less than 6 feet do not require a permit from Bullitt County Planning & Zoning, but must conform to applicable easements, setbacks, and sight distances.

• Residential Corner-Lot Visibility: On a corner lot in a residential district, no obstruction may materially impede vision between 2.5 feet and 10 feet above the centerline grades of intersecting streets within the visibility triangle measured 90 feet from the point of intersection along the intersecting street centerlines. Existing trees may remain if their branches are not closer than 6 feet to the ground.

• SmartCode Side and Rear Yard Fences: In areas governed by the Mt. Washington SmartCode, side- and rear-yard fences must be at least 3 feet and not more than 7 feet in height.

• SmartCode Streetscreens: In SmartCode areas, streetscreens must be at least 3 feet and not more than 8 feet in height. A streetscreen may be replaced by a hedge or fence only where the SmartCode waiver process allows it.

• Swimming Pool Enclosures: Swimming-pool enclosures, including gates, must be at least 4 feet high. Pool-enclosure gates must be self-latching, with latch placement meeting the City’s pool-enclosure rule.

MATERIAL AND CONSTRUCTION LIMITS

• Standard Residential Fence Materials: The code does not specify a general citywide list of permitted or prohibited materials for standard residential fences outside special regulating contexts.

• SmartCode Frontage Fences: In Mt. Washington SmartCode areas, fences facing frontages must be wood or metal pickets.

• SmartCode Side and Rear Yard Materials: In SmartCode areas, fences away from frontages may be closed wood boards, masonry, trellis, lattice, hedge, or a combination of those materials, and may include brick or stone piers.

• SmartCode Garden Walls and Gates: In SmartCode areas, garden walls must be made of stone, brick, or stucco. Gates within garden walls must be made of wood or metal.

• Hedges: Hedges are treated with fences and walls in the zoning regulations. They are permitted in yards or along yard edges outside required front-yard visibility limits, but may not be used to materially impede required front-yard or corner-lot visibility.

• Pool Enclosures: A natural barrier, hedge, pool cover, or other protective device may substitute for a pool enclosure only where approved as providing protection at least equivalent to the required pool enclosure.

• Unspecified Materials: The code does not specify a standard residential rule for chain link, vinyl, ornamental metal, wood privacy fences, finished-side orientation, barbed wire, electric fencing, razor wire, or fence-post materials for ordinary residential fences.

PRIVATE RESTRICTIONS

Private restrictions operate independently from City and Bullitt County zoning or permit review. A fence that satisfies public regulations may still be limited by private covenants, HOA rules, subdivision restrictions, deed restrictions, architectural-control covenants, private easements, recorded plats, private maintenance agreements, boundary agreements, or other private property documents.

Recorded subdivision plats may show easements, rights-of-way, setback lines, protective covenants, drainage features, utility locations, and other site limitations that affect fence placement. The City and Bullitt County source materials do not state that private HOA or deed restrictions are enforced as City fence rules.

REVIEW AND ENFORCEMENT CONTEXT

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

• Bullitt County Planning & Zoning Review: Fence projects may be reviewed for the published 6-foot permit note, 7-foot inspection threshold, easement compliance, setback compliance, and sight-distance compliance.

• City Permit Review: Projects requiring City permit review use the City building and zoning-compliance workflow, including zoning-compliance information from Bullitt County Planning & Zoning where applicable.

• Front-Yard Visibility: Required front-yard fences and walls may be reviewed if they materially impede vision above 30 inches.

• Corner-Lot Visibility: Residential corner-lot fences, walls, hedges, plantings, and other obstructions may be reviewed if they affect the required visibility triangle between 2.5 feet and 10 feet above street centerline grades.

• Right-of-Way and Easement Conflicts: Fence construction or removal in a City right-of-way or easement may require encroachment approval, and fences may not obstruct streets, alleys, sidewalks, or other public ways.

• SmartCode Areas: Properties governed by the Mt. Washington SmartCode may be reviewed for fence materials, frontage conditions, side- and rear-yard fence height, streetscreen height, garden-wall materials, and Town Architect compliance.

• Pool Barriers: A fence used as a swimming-pool enclosure may be reviewed under the City’s pool-enclosure requirements, including the 4-foot enclosure height and self-latching gate requirements.

• Stormwater and Floodplain Conditions: Fence work that is part of land disturbance, drainage changes, work in a special flood hazard area, or work affecting watercourses may be reviewed under stormwater or floodplain requirements.

• Subdivision and Plat Conditions: Recorded subdivision plats, easements, setback lines, protective covenants, drainage facilities, rights-of-way, utility locations, and subdivision sight-line requirements may affect where a fence can be placed.
