FENCE RULES – HARRISON (COUNTY), INDIANA

OVERVIEW

This page covers residential fence rules administered by Harrison County in unincorporated Harrison County. The Harrison County Advisory Plan Commission also provides planning administration for Crandall, Elizabeth, Laconia, Lanesville, Mauckport, Milltown, New Amsterdam, New Middletown, and Palmyra. Corydon maintains its own plan commission. Properties within incorporated municipalities may be subject to municipal ordinances or separate administrative requirements.

Harrison County allows fences, lattice-work, screens, hedges, and walls up to 7 feet in required side and rear yards. A front-yard hedge is limited to 3 feet. The zoning ordinance does not publish a general numeric fence-to-property-line setback or material-specific standards for wood, vinyl/PVC, or chain-link. Harrison County also does not publish a fence-specific permit requirement or exemption for standard residential fences. Separate requirements apply in certain floodplain, right-of-way, subdivision, agricultural, regulated-drain, pool-barrier, and excavation conditions. Updated September 2026.

Quick question	Harrison County answer
Permit or approval	Harrison County does not publish a fence-specific permit requirement or exemption for standard residential fences. Separate approval applies in certain conditions, including fences in Special Flood Hazard Areas, work within County right-of-way, and specified subdivision-development situations.
Typical fence height	In required side and rear yards, fences, lattice-work, screens, hedges, and walls may be up to 7 feet. A front-yard hedge is limited to 3 feet. The ordinance does not publish a general front-yard height standard for ordinary constructed fences. Fences connected with agricultural use may be any height.
Placement & property lines	The zoning ordinance does not publish a general numeric fence-to-private-property-line setback. Separate location limits can arise from road rights-of-way, easements, regulated drains, floodplain conditions, and subdivision requirements. Certain new-subdivision perimeter fences are required on the property line.
Common fence materials	Wood: no separate material-specific standard published. Vinyl/PVC: no separate material-specific standard published. Chain-link: no separate material-specific standard published.
Important local conditions	Fence rules may be further affected by new subdivisions adjoining agricultural land, exempt ten-acre divisions, agricultural use, floodplain or floodway location, County or state road right-of-way, regulated drains, swimming-pool barrier use, Indiana 811 excavation requirements, and private HOA, deed, or recorded easement restrictions.

The sections below explain the applicable height, placement, permit, subdivision, floodplain, drainage, road, pool, and utility requirements in more detail. Before purchasing materials or beginning construction, review the provisions that apply to the property and confirm site-specific requirements with the Harrison County Plan Commission / Planning & Zoning Office or the responsible agency for the particular condition.

GOVERNANCE

Residential fence regulation in unincorporated Harrison County is administered primarily through the Harrison County Board of County Commissioners and the Harrison County Advisory Plan Commission. The controlling local zoning source is the Harrison County Zoning Ordinance, amended September 15, 2025. The Plan Commission / Planning & Zoning Office processes zoning matters, subdivision applications, Improvement Location Permits, building permits and inspections, certificates of occupancy, and related land-use administration.

The Harrison County planning system also serves Crandall, Elizabeth, Laconia, Lanesville, Mauckport, Milltown, New Amsterdam, New Middletown, and Palmyra. Corydon is outside the County Plan Commission system and maintains its own plan commission. For property inside an incorporated municipality, the applicable municipal ordinances and administrative arrangements control.

Responsibility is divided by subject. The Plan Commission Administrator serves as Floodplain Administrator for the county floodplain program. The Harrison County Highway Department administers County right-of-way permits. The Harrison County Surveyor oversees the County Drainage Board for regulated-drain and drainage-board matters.

Indiana building and fire-safety rules apply statewide within their scope. Harrison County administers local building permits and inspections. The current statewide residential code is the 2020 Indiana Residential Code, 675 IAC 14-4.4, based on the 2018 International Residential Code with Indiana amendments. Indiana deleted model IRC Section R105, so Indiana does not have the model-code seven-foot fence permit exemption as a statewide rule.

PERMIT AND APPROVAL REQUIREMENTS

• Ordinary residential fence permit: Harrison County has a general Improvement Location Permit system, but the county does not publish a fence-specific local permit requirement or exemption for standard residential fences. The residential plot-plan requirements do not list a standard residential fence as a separate permit type.

• Improvement Location Permit plans: When an application requires a detailed site plan, walls, fences, and landscaping are among the site features shown on the plan.

• Special Flood Hazard Area: Harrison County defines erection of walls and fences as floodplain "development." A Floodplain Development Permit is required before development begins in a Special Flood Hazard Area (SFHA). The application may require a site development plan and other location or elevation information appropriate to the property and project.

• Identified floodway: For work in an identified floodway, Indiana Department of Natural Resources (DNR) authorization may be required before the local floodplain approval is issued. The local Floodplain Development Permit may not be less restrictive than the state floodway authorization. Indiana law also provides a limited exemption for qualifying agricultural fences used primarily to keep animals in or out when the fence does not obstruct floodwater or debris.

• County right-of-way: The Harrison County Highway Department right-of-way permit process applies to nonemergency work performed within Harrison County right-of-way. The current Right-of-Way Permit fee is $50. Ordinance 2026-5 contains an agricultural exemption.

• New major subdivision adjoining agricultural or reserved land: When the subdivision perimeter-fence requirement applies, the subdivider must enter a written agreement with the adjoining property owner concerning installation, cost, and equal maintenance. The agreement is recorded before the secondary plat is executed. If the adjoining owner does not sign within 90 days after receiving the agreement, or within another reasonable period set by the Plan Commission, the subdivider is not required to install the perimeter fence at that time; later requests are governed by Indiana law.

• Exempt ten-acre divisions: The subdivision ordinance requires the perimeter of the original tract to be identified with a lawful partition fence before transfer or creation of a lot, subject to a Plan Commission Administrator waiver in whole or in part. Existing fencing can satisfy the requirement when the adjoining property owner provides the required written acceptance.

• Indiana permit framework: Indiana deleted model IRC Section R105 from the state residential code. As a result, the model IRC seven-foot fence permit exemption is not an Indiana statewide permit rule. Local zoning, building, floodplain, right-of-way, subdivision, drainage, and other approvals apply according to the provisions governing those conditions.

FENCE PLACEMENT RULES

• Required side and rear yards: Fences, lattice-work, screens, hedges, and walls not more than 7 feet high may be located in a required side or rear yard. The ordinance does not publish a separate numeric fence-to-property-line setback for this provision.

• Front yard: A hedge in a front yard must be maintained at 3 feet or less. The zoning ordinance does not publish a general front-yard height standard for ordinary constructed fences in the same provision. Retaining walls are separately listed as accessory uses that may be located in required front, side, or rear yards.

• Property-line setback: Harrison County does not publish a general numeric setback requiring a standard residential fence to stand a stated number of feet inside a private lot line. The ordinance separately requires accessory buildings to be at least three feet from a side lot line; that standard applies to accessory buildings, not fences.

• New subdivision perimeter fence: Under the Harrison County Subdivision Control Ordinance, a required perimeter fence for a new major subdivision adjoining A-R-zoned land or land used for crops, livestock, or conservation is ordinarily placed on the property line. It may be placed on the subdivision lot or in a common area when the adjoining owners agree, significant existing vegetation makes property-line installation impractical, or the Plan Commission determines another location better serves the properties. When the fence is shifted inward under this rule, no structures may be located between the fence and the adjoining property line.

• Agricultural-edge grass buffer in newly platted land: Land platted immediately adjacent to agricultural land must include a 25-foot-wide grass buffer in which trees, ornamental flowers, vines, shrubs, and vegetable gardens are prohibited. The 25-foot requirement is a subdivision landscaping buffer, not a general fence setback.

• Exempt ten-acre divisions: Each interior lot line must be identified with inter-visible fiberglass or metal T-posts spaced no more than 300 feet apart, subject to the stated roadway exception. Where a sinkhole or sinkhole-type depression exists on the parcel, the deed must include a restrictive easement protecting land at least 66 feet from the center of the depression or sinkhole eye; land-disturbing activity and structures are prohibited within the protected area.

• County and state road rights-of-way: Road-edge features such as pavement, curbs, ditches, mowing lines, and existing fences are not legal property or right-of-way boundary markers. Work within Harrison County right-of-way is subject to the County permit system. Property along a state highway can also be subject to Indiana Department of Transportation right-of-way and encroachment requirements.

• Regulated drains: Indiana regulated-drain law creates a statutory access and right-of-way framework administered locally through the County Surveyor and Drainage Board. Depending on the drain and statutory adjustments, the corridor can extend up to 75 feet measured from the centerline of a tiled drain or the top of bank of an open drain. A permanent structure in the statutory right-of-way requires drainage-board consent. The regulated-drain corridor is site-specific and is not a countywide 75-foot residential fence setback.

• Property boundaries and recorded interests: Assessor maps, tax maps, visible occupation lines, tree lines, hedges, and existing fences do not establish the legal private boundary. Recorded easements, plats, right-of-way documents, and survey monuments can affect fence placement even where the zoning ordinance publishes no numeric fence setback.

• Indiana 811 before post-hole excavation: Before covered digging, augering, drilling, or other excavation for fence posts, submit a locate request through Indiana 811. Indiana Utility Regulatory Commission underground-facility guidance states that a locate ticket is valid for 20 calendar days. Indiana law requires notice at least two full working days before excavation, not counting the day notice is submitted, and no more than ten calendar days before the expected start. An owner or tenant using only hand tools on the person's own property is exempt when excavation is 12 inches or less deep. The exception does not extend to powered augers, deeper excavation, contractor work, or easement work.

FENCE HEIGHT AND VISIBILITY RULES

• Side and rear yard maximum: Fences, lattice-work, screens, hedges, and walls may be up to 7 feet high in required side and rear yards.

• Front-yard hedge: A hedge in a front yard must be maintained at 3 feet or less. The zoning ordinance does not publish a general front-yard height limit for ordinary constructed fences in the same provision.

• Agricultural use: A fence connected with an agricultural use may be constructed or maintained at any height under the county zoning provision. The agricultural-use exception applies to fences associated with agricultural use.

• Corner-lot vision-clearance definition: The zoning ordinance defines a corner-lot vision-clearance triangle as an area free from visual obstruction between 3 and 12 feet above established grade, with the diagonal connecting points 15 feet from the street corner along each property line. The ordinance does not publish this definition as a general fence-specific setback or height standard for every residential corner lot.

• Indiana spite-fence law: Indiana law treats a structure in the nature of a fence that unnecessarily exceeds 6 feet and is maliciously erected or maintained to annoy an adjoining owner or occupant as a nuisance. This statewide nuisance provision is separate from Harrison County's seven-foot side/rear zoning allowance.

• Private residential pool barrier: When a fence serves as a required barrier for a private residential swimming pool, Indiana's residential code applies separate safety requirements. One recognized wall/fence barrier method is at least 4 feet high with qualifying gate or door controls. The four-foot standard applies to pool barriers rather than to ordinary Harrison County yard fences.

MATERIAL AND CONSTRUCTION LIMITS

• Wood: The county zoning ordinance does not publish a separate wood-specific standard for standard residential fences.

• Vinyl/PVC: The county zoning ordinance does not publish separate residential standards for vinyl/PVC color, opacity, orientation, or construction.

• Chain-link: The county zoning ordinance does not publish a separate residential chain-link material standard.

• Other standard residential fence construction: The county zoning ordinance does not publish countywide residential standards for finished-side orientation, opacity percentage, picket spacing, or a general material list for masonry, aluminum, wrought iron, composite, wire, and similar fence types. It also does not publish a separate standard residential rule for barbed wire, razor wire, or electric fencing.

• Walls, screens, lattice-work, and hedges: The seven-foot side/rear-yard provision applies to fences, lattice-work, screens, hedges, and walls. Retaining walls are separately recognized as accessory uses permitted in required front, side, or rear yards.

• Subdivision agricultural-edge fence: A required perimeter fence under the new-major-subdivision agricultural-edge rule must be sufficiently tight and strong to hold cattle, hogs, horses, mules, and sheep and must meet the referenced Indiana partition-fence standard unless the adjoining property owners agree in writing to an alternative fence type or to no fence. An existing partition fence in good repair can satisfy the rule when identified in the written agreement.

• Pool-barrier construction: A fence used as a residential swimming-pool barrier must satisfy Indiana residential-code barrier and gate requirements. These standards apply when the fence serves as a pool barrier.

PRIVATE RESTRICTIONS

Homeowners association covenants, private subdivision restrictions, deed restrictions, architectural-review covenants, recorded private easements, boundary agreements, conservation easements, and other private instruments operate independently from Harrison County zoning and may be more restrictive. County zoning compliance does not establish compliance with a private covenant or authorize construction on another person's land.

Harrison County's subdivision ordinance also uses recorded agreements for specific public subdivision requirements. The new-major-subdivision agricultural-edge fence provision requires a written, recorded agreement addressing installation, cost, and maintenance between the subdivider and adjoining owner when that rule applies. Exempt ten-acre divisions can rely on written acceptance of an existing partition fence. These recorded subdivision agreements are separate from HOA covenants and other private neighborhood restrictions.

Public drainage or utility easements, road rights-of-way, and regulated-drain statutory corridors are separate from private covenants. A fence that meets the county's ordinary seven-foot side/rear-yard rule may also be subject to a recorded easement or statutory access restriction.

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 compliance: The Plan Commission / Planning & Zoning Office reviews applicable fence, wall, hedge, lattice-work, and screen requirements under the zoning ordinance.

• Improvement Location Permit administration: When an Improvement Location Permit applies to the project or broader construction, the Administrator reviews the submitted plan for zoning compliance. Harrison County's published ILP materials do not state a fence-specific trigger or exemption for standard residential fences.

• Floodplain review: A fence or wall in an SFHA is floodplain development and is reviewed through the Floodplain Development Permit process. Work in an identified floodway can also require Indiana DNR authorization.

• County right-of-way: Nonexempt work inside Harrison County right-of-way is subject to Highway Department permit review and Ordinance 2026-5.

• Subdivision conditions: Applicable subdivision review can include agricultural-edge perimeter-fence agreements, fence type and location, the 25-foot grass buffer on newly platted land adjoining agriculture, exempt ten-acre division fencing and lot-line markers, and sinkhole restrictive-easement conditions.

• Agricultural and partition-fence conditions: The county's any-height fence provision applies to fences connected with agricultural use. Qualifying partition-fence situations can also be governed by Indiana fence law and recorded agreements.

• Drainage, road, and utility conditions: Separate review can apply when a fence occupies a regulated-drain corridor, enters a public right-of-way, or involves covered excavation near underground facilities. Indiana 811 notice addresses underground-utility excavation and is separate from zoning, floodplain, drainage, and road approvals.
