FENCE RULES – JOHNSON (COUNTY), INDIANA

OVERVIEW

This page applies to property within Johnson County that is subject to Johnson County zoning jurisdiction. The Johnson County Unified Development Ordinance applies to land where no municipal jurisdiction has zoning powers and control, as shown on the County's Jurisdictional Area Map. Property governed by a city or town zoning system is outside the ordinary county zoning scope described here.

Johnson County requires an Improvement Location Permit (ILP) for all fences within its zoning jurisdiction. For lots zoned Single-Family Dwelling Residential (SR), Duplex Residential (DR), or Multi-Family Dwelling (MR), fences are limited to 3.5 feet in front yards and 6 feet in side or rear yards, with a corner-lot exception allowing one required front yard to reach 6 feet. Those districts also prohibit barbed, razor, and electrified wire, restrict chain-link construction, and bar fences from drainage or utility easements. Countywide sight-clearance and right-of-way rules can apply beyond those three districts. Updated August 2026.

Quick question	Johnson County answer
Permit or approval	Yes. Johnson County requires an Improvement Location Permit (ILP) for all fences within the County UDO jurisdiction. The County does not publish a separate fence-specific structural building-permit requirement for a standard residential fence. Drainage, pool, road/right-of-way, floodway, stormwater, or other site conditions can create additional review.
Typical fence height	For lots zoned Single-Family Dwelling Residential (SR), Duplex Residential (DR), or Multi-Family Dwelling (MR), the maximum is 3.5 feet in a front yard and 6 feet in a side or rear yard. On a corner lot, one, but not both, required front yards may have a fence up to 6 feet. The UDO does not extend this height rule to Agricultural (AG), Agricultural / Residential (AR), or Manufactured Home Park (MH) districts.
Placement & property lines	The UDO does not publish a fence-specific numeric setback from a private property line. Fences may not occupy a public right-of-way. In SR, DR, and MR districts, a fence may not be erected in a drainage or utility easement. Separate County stormwater rules also restrict fences in drainage easements and require County Drainage Board acceptance for encroachments into County Regulated Drainage Easements.
Common fence materials	Wood: not specifically addressed by the ordinary residential fence subsection. Vinyl/PVC: not specifically addressed as an ordinary fence material. Chain-link: restricted on SR, DR, and MR lots to vinyl-coated black or dark green chain link with no slats.
Important local conditions	Fence rules may be further affected by corner-lot and driveway sight areas, subdivision visibility covenants, drainage and utility easements, County regulated drains, swimming-pool barrier use, accessory solar screening, road or INDOT rights-of-way, rural or agricultural conditions, and private HOA or deed restrictions.

Before purchasing materials or beginning construction, read the sections that apply to the property, review the linked official sources, and confirm site-specific questions with the Johnson County Department of Planning and Zoning or the responsible office identified for that issue.

GOVERNANCE

Johnson County administers local zoning and subdivision regulation through the Johnson County Department of Planning and Zoning and the Johnson County Plan Commission. The controlling land-use document is the Johnson County Unified Development Ordinance. The UDO applies where no municipal jurisdiction has zoning powers and control, rather than automatically to every parcel within the geographic county.

The UDO combines the County's zoning and subdivision-control systems. The Johnson County Commissioners are the legislative body for the UDO; the Department of Planning and Zoning administers Improvement Location Permits and day-to-day zoning administration; and the Plan Commission and Board of Zoning Appeals perform the review functions assigned to them by the ordinance.

Fence regulation is distributed across several County systems. The UDO controls the fence ILP, residential district height and material rules, sight clearance, rights-of-way, and subdivision standards. The Johnson County Surveyor and County Drainage Board administer County regulated-drain and drainage-easement encroachments. County road or INDOT authority can apply where work enters a public or state-highway right-of-way.

Johnson County also administers local building permits under its Building Code. For standard residential fences, however, the current UDO and County Code do not publish a separate fence-specific structural building-permit requirement or exemption. The affirmative County land-use approval expressly tied to fences is the ILP.

Indiana's currently effective residential-code framework is the 2020 Indiana Residential Code, 675 IAC 14-4.4, based on the 2018 International Residential Code with Indiana amendments. Indiana replaced model IRC Section R105, so the model-code seven-foot fence permit exemption is not an Indiana statewide rule. Local permit treatment must therefore come from the applicable County or municipal requirements.

PERMIT AND APPROVAL REQUIREMENTS

• Improvement Location Permit (ILP): Johnson County requires an ILP for the erection, alteration, or modification of all fences within the UDO jurisdiction. The application is filed under the County's adopted ILP process, and the applicable fee is collected before issuance. The UDO also provides for a final inspection of work covered by an ILP. Johnson County Improvement Location Permit application

• Structural building permit: Johnson County publishes building-permit administration for residential construction, but the current UDO and County Code do not publish a separate structural building-permit requirement or fence-specific exemption for a standard residential fence. The required local fence approval that is expressly published is the ILP.

• Indiana model-code permit exemption: Do not apply the model IRC rule that exempts certain fences seven feet or less from permitting. Indiana replaced model Section R105 in the 2020 Indiana Residential Code, so that model exemption does not operate as a statewide Indiana fence-permit rule.

• County regulated-drain or drainage-easement condition: The County stormwater ordinance states that structures and fences may not be erected in a drainage easement unless otherwise accepted by Johnson County, and any outlet, crossing, or encroachment of a County Regulated Drainage Easement requires application and acceptance from the County Drainage Board. The UDO separately states that fences on SR, DR, and MR lots may not be erected in drainage or utility easements. Johnson County legal-drain encroachment application

• Stormwater or land-disturbance condition: Johnson County stormwater requirements can apply when a project involves clearing, grading, excavation, or other land disturbance within the stormwater ordinance's scope. The County does not publish an automatic Stormwater Permit requirement solely because a standard fence ILP is required; the separate stormwater trigger depends on the land-disturbance and project conditions.

• Private residential pool barrier: When a fence is used to restrict access to a residential swimming pool, Indiana's residential code requires a compliant access barrier. One accepted method is walls or fencing at least 4 feet high completely surrounding the pool and deck area, with self-closing and latching gates and doors capable of being locked. Other approved barrier methods may be used under the state code.

• Road, right-of-way, or state-highway work: The fence ILP does not authorize occupation of a public road right-of-way. The UDO prohibits fences in a right-of-way, and separate County Highway or INDOT approval can apply when related excavation, access, or construction enters a public or state-highway right-of-way.

FENCE PLACEMENT RULES

• Public right-of-way: Johnson County's UDO states that walls, fences, and signs are not permitted in a public right-of-way. The apparent edge of pavement, ditch, mowing line, curb, or an existing fence line should not be treated as proof of the legal right-of-way or property boundary.

• Private property line: The UDO does not publish a fence-specific numeric setback from an ordinary private property line. A property line is still distinct from a public right-of-way, recorded easement, County regulated-drain easement, drainage swale, or other restricted area.

• SR, DR, and MR drainage or utility easements: On lots zoned Single-Family Dwelling Residential (SR), Duplex Residential (DR), or Multi-Family Dwelling (MR), the UDO states that a fence may not be erected in any drainage or utility easement.

• Other County drainage easements: The County stormwater ordinance separately prohibits structures and fences in drainage easements unless otherwise accepted by Johnson County. An encroachment into a County Regulated Drainage Easement requires County Drainage Board acceptance. Johnson County legal-drain encroachment application

• Subdivision drainage swales: For secondary plats, County-required covenant language protects drainage swales and ditches along dedicated roads and in dedicated drainage easements from being altered, dug out, filled, tiled, or otherwise changed without a compliant drainage system and written approval from the County Surveyor. Fence work should not be used to obstruct or alter those drainage features.

• Corner-lot and driveway sight areas: Fence placement must preserve the sight-clearance areas described in the next section. Those restrictions are measured from street right-of-way lines and also apply near the intersection of a street right-of-way line with a driveway pavement edge or alley line.

• Residential accessory solar screening: If a fence is used to screen a residential ground-mounted accessory solar energy system, the solar equipment must be outside the front yard, behind the front facade, and properly screened by a fence. The solar equipment may not exceed 6 feet or the height of the screening fence, whichever is less. The solar system also has separate easement, County Drain, and right-of-way restrictions.

• Rural and agricultural boundaries: Qualifying agricultural partition fences, livestock boundaries, and other farm-adjacent conditions can be governed by separate Indiana fence statutes. Those statewide rules do not replace the County ILP, right-of-way, sight-clearance, drainage, or zoning-district rules that apply to the site.

• Indiana 811 before digging: Before covered excavation for fence-post holes, submit a locate request through Indiana 811 at least two full working days before digging. A locate ticket is valid for 20 calendar days. Indiana publishes a narrow exception when an owner or tenant uses only hand tools on the person's own property and does not excavate more than 12 inches below the surface; that exception does not extend to powered equipment, deeper digging, or other excavation outside its terms.

FENCE HEIGHT AND VISIBILITY RULES

• Single-Family Dwelling Residential (SR), Duplex Residential (DR), and Multi-Family Dwelling (MR) – side or rear yards: A fence in a side or rear yard may not exceed 6 feet in height.

• SR, DR, and MR – front yards: A fence in a front yard may not exceed 3.5 feet in height.

• SR, DR, and MR – corner lots: On a corner lot, a front-yard fence may be up to 6 feet tall within one, but not both, of the required front yards. The separate sight-clearance rules still apply.

• Agricultural (AG), Agricultural / Residential (AR), and Manufactured Home Park (MH) districts: Single-family dwellings can occur in these districts, but the UDO's 3.5-foot front-yard and 6-foot side/rear fence subsection is expressly written for SR, DR, and MR lots. The UDO does not publish that same ordinary fence-height framework for AG, AR, or MH lots.

• Countywide corner-lot sight triangle: No fence, wall, hedge, tree, shrub, sign, or other object that obstructs sight lines between 2.5 feet and 8 feet above the street may be placed or remain within the triangle formed by the intersecting street right-of-way lines and a line connecting points 35 feet from their intersection. For a rounded property corner, the measurement uses the intersection of the right-of-way lines extended.

• Driveway and alley sight area: The same 2.5-foot-to-8-foot sight-line restriction applies to the area within 10 feet of the intersection of a street right-of-way line with the edge of a driveway pavement or an alley line.

• Secondary-plat visibility covenant: Johnson County requires visibility language in the restrictive covenants and deeds for secondary plats. That covenant uses a 2.5-foot-to-8-foot obstruction band and a corner triangle extending 40 feet along neighborhood and local road right-of-way lines, or 75 feet along arterial-street right-of-way lines. It also carries the 10-foot driveway/alley sight-area restriction. Because this recorded covenant can be more restrictive than the general 35-foot UDO triangle, subdivision lots should be checked for the recorded covenant that applies to the property.

• Fence-height measurement: The ordinary SR/DR/MR fence subsection states the maximum heights above but does not publish a separate fence-specific measurement method for grade, posts, columns, or caps. Do not substitute building-height rules for a fence-height rule unless the County expressly applies them to the project.

• Indiana spite-fence context: Indiana law separately 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. That statewide rule is not a general 6-foot zoning maximum and does not replace Johnson County's district-specific height standards.

MATERIAL AND CONSTRUCTION LIMITS

• SR, DR, and MR prohibited materials: Barbed wire, razor wire, electrified wire, and similar materials are prohibited for fences on lots zoned SR, DR, and MR.

• SR, DR, and MR chain-link fences: Chain-link fences must be vinyl-coated black or dark green and may not be filled with slats.

• Wood: The ordinary SR/DR/MR fence subsection does not specifically identify wood as an allowed or prohibited residential fence material. That silence should not be converted into an affirmative material approval.

• Vinyl/PVC: The ordinary residential fence subsection does not specifically identify vinyl or PVC panel fencing as an allowed or prohibited material. The separate requirement that chain-link be vinyl-coated does not establish a general rule for vinyl/PVC fence systems.

• Other fence materials: The ordinary residential fence subsection does not publish a general approved-material list for aluminum, wrought iron, steel, composite, masonry, stone, split rail, picket, horizontal-board, wire-mesh, or similar fence systems. A project involving a wall, structural component, special use, or special site condition may enter a different County or state rule.

• Finished side, opacity, and decorative construction: Johnson County does not publish a general finished-side orientation, ordinary residential opacity percentage, picket-spacing, or fence-post/cap rule in the SR/DR/MR fence subsection. Separate screening rules for dumpsters, commercial uses, towers, solar facilities, and other specialized uses should not be treated as ordinary residential fence standards.

• Gates: The UDO definition of a fence includes entrance and exit gates, so a gate that is part of the enclosure is part of the regulated fence. Pool-barrier gates have the separate state safety requirements described below.

• Residential pool-barrier construction: When the fence serves as a required residential pool barrier, one accepted Indiana-code method is a wall or fence at least 4 feet high completely surrounding the pool and deck area, with self-closing and latching gates and doors capable of being locked. Pool-barrier use is a separate safety condition and should not be used as the ordinary yard-fence height rule.

• Qualifying boundary hedges and live fences: Indiana law contains separate rules for qualifying boundary hedges or live fences, including a statewide height-and-width framework in the circumstances covered by that statute. Those provisions apply to qualifying live boundary fences and should not be applied to every ornamental shrub or privacy planting.

PRIVATE RESTRICTIONS

Homeowners-association covenants, architectural-review rules, subdivision restrictions, deed restrictions, private easements, boundary agreements, agricultural agreements, recorded partition-fence agreements, and other private instruments operate independently from Johnson County's public fence regulations and may be more restrictive.

Johnson County's UDO expressly distinguishes private covenants from County zoning rules. The County enforces regulations contained in the UDO; private restrictive covenants are enforced by the homeowners association or affected property owners through civil proceedings rather than through ordinary County zoning enforcement.

The County-required secondary-plat visibility covenant is an important special case. Johnson County requires the sight-line language to be included in restrictive covenants and deeds for secondary plats, but once recorded it operates as a property restriction in addition to the UDO's general 35-foot sight triangle. A fence project on a subdivision lot should therefore be checked against both the County UDO and the recorded restrictions for that lot.

A County ILP does not establish a private boundary, grant a right to occupy an easement, or override an HOA, deed restriction, private agreement, or adjoining owner's property rights.

REVIEW AND ENFORCEMENT CONTEXT

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

• ILP review: The Department of Planning and Zoning reviews the fence project through the Improvement Location Permit process, including the applicable UDO location, height, material, easement, and sight-clearance standards.

• Final inspection: The UDO provides for final inspection of work covered by an ILP. A fence should be constructed in the approved location and configuration so the completed work remains consistent with the permit and applicable UDO standards.

• Height and material review in SR, DR, and MR districts: Review can include the 3.5-foot front-yard maximum, 6-foot side/rear maximum, corner-lot exception, hazardous-material prohibition, and chain-link coating/no-slats requirement.

• Sight-clearance review: Corner-lot, driveway, and alley conditions can be reviewed under the UDO's 35-foot corner triangle and 10-foot driveway/alley sight areas. A subdivision lot can also carry the County-required recorded visibility covenant using 40-foot or 75-foot corner measurements.

• Drainage and regulated-drain review: A fence in or near a drainage easement or County Regulated Drainage Easement can require separate review by the County Surveyor or Drainage Board. In SR, DR, and MR districts, the UDO itself bars fences from drainage and utility easements.

• Pool-barrier review: A fence used as a residential pool barrier must satisfy the separate Indiana residential-code access-control requirements rather than only the ordinary yard-fence standards.

• Road and utility excavation: Right-of-way restrictions and Indiana 811 excavation requirements operate independently from the fence ILP when the work enters a public right-of-way or involves covered digging.

• UDO violations: The County UDO authorizes notice of violations, corrective action, administrative appeal to the Board of Zoning Appeals, and other enforcement remedies. Private HOA or deed restrictions remain outside ordinary County UDO enforcement.
