FENCE RULES – LAKE (COUNTY), INDIANA
OVERVIEW
This page applies to unincorporated Lake County, Indiana, the territory administered by the Lake County Plan Commission under the county zoning and subdivision system. Incorporated cities and towns have their own land-use ordinances and are outside this county-page scope unless a separate official arrangement makes a county function applicable.
Lake County publishes a detailed residential fence framework. Residential fences are subject to building-permit review, may reach 6 feet along interior side and rear lot lines and yards, and are limited to 3.5 feet in street-yard areas. Fences may not occupy an existing or planned street right-of-way. The Unified Development Ordinance also regulates corner-lot visibility, drainage easements, hazardous fence materials, and regulated-drain easements. In Special Flood Hazard Areas, fence erection is regulated as floodplain development. Pool barriers, Indiana 811 excavation requirements, and private covenants can add separate conditions.
| Quick question | Lake County answer |
|---|---|
| Permit or approval | Fence permit / building-permit review applies. Fences are exempt from site-plan review under the general UDO provision, but remain subject to UDO standards and building-permit review. Fence permits are valid for six months. Special floodplain, regulated-drain, pool, or other site approvals may also apply. |
| Typical fence height | 6 feet along interior side and rear lot lines and within interior side and rear yards; 3.5 feet in street-yard areas. |
| Placement & property lines | Fences may be placed along interior side and rear lot lines, but may not be placed in an existing or planned street right-of-way. Easements, regulated drains, drainage flow, corner-lot visibility, and floodplain status can further affect placement. |
| Common fence materials | The UDO does not establish separate residential material standards for wood, vinyl/PVC, or chain-link. Barbed wire, razor concertina/concertina wire, electric fencing, and similar hazardous materials are prohibited in residential zoning districts. |
| Important local conditions | Fence rules may be further affected by corner-lot visibility, street rights-of-way, drainage or utility easements, regulated-drain corridors, mapped floodplain or floodway status, pools, rural/agricultural property, and Indiana 811 excavation requirements. |

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 Lake County Plan Commission / Planning & Building Department or the responsible office identified for the issue. Current local and state sources were verified in September 2026.
GOVERNANCE
The Lake County Council adopts county ordinances for the unincorporated jurisdiction. The Lake County Plan Commission and its Planning & Building Department administer zoning, subdivision regulation, building permits, inspections, and zoning enforcement in unincorporated Lake County. The county planning system does not extend its ordinary zoning jurisdiction into incorporated cities and towns.
The principal local land-use source is Unified Development Ordinance No. 2560. It combines zoning and subdivision standards and contains the county rules for residential fence height, street-yard placement, rights-of-way, corner visibility, hazardous fence materials, easements, drainage clearance, and regulated-drain plat provisions.
The Planning & Building Department administers the county building-permit system. Lake County’s published inspection requirements expressly recognize fence permits and state that they are valid for six months.
In mapped flood hazard areas, the Lake County Plan Commission also administers Flood Damage Prevention Ordinance No. 2559. The ordinance applies to Special Flood Hazard Areas in unincorporated Lake County and establishes a Floodplain Development Permit system for covered development.
Drainage-related fence issues may involve the Lake County Surveyor and Lake County Drainage Board. The UDO’s subdivision provisions include regulated-drain easement language that requires written County Surveyor approval before a fence is placed in a designated regulated-drain easement.
Indiana building and excavation requirements supplement these county rules. The statewide residential-code framework is the 2020 Indiana Residential Code, 675 IAC 14-4.4. Indiana deleted model IRC Section R105, so the model-code fence exemption for fences not over seven feet is not part of the Indiana residential code.
PERMIT AND APPROVAL REQUIREMENTS
• Fence permit / building-permit review: Lake County subjects fences to building-permit review. The UDO exempts fences, hedges, and walls from the general site-plan-review requirement, while expressly retaining UDO compliance and building-permit review.
• Fence-permit duration: Lake County’s inspection requirements state that fence permits are valid for six months.
• Permit documentation: Lake County Building Code No. 18 requires permit applications to include property and project information, including a plat or sketch showing lot boundaries and the project location, together with required plans or specifications.
• Indiana residential-code context: The Indiana Fire Prevention and Building Safety Commission code page identifies the 2020 Indiana Residential Code, 675 IAC 14-4.4, as the current statewide residential-code rule. Indiana deleted model IRC Section R105, so the model-code work exemption for fences not over seven feet does not apply as an Indiana statewide fence-permit exemption.
• Property in a Special Flood Hazard Area: Flood Damage Prevention Ordinance No. 2559 requires a Floodplain Development Permit before development begins in a Special Flood Hazard Area. For floodplain-management purposes, the ordinance expressly includes the erection of walls and fences within the definition of development. The permit requirement applies to development located wholly within, partially within, or in contact with a Special Flood Hazard Area.
• Mapped floodway property: The UDO prohibits development in a Special Flood Hazard Area classified as Floodway or identified as floodway on the applicable flood map. Flood Damage Prevention Ordinance No. 2559 also addresses Indiana Department of Natural Resources authorization for floodway development and provides that, where regulations overlap, the more stringent restriction prevails.
• Flood Fringe / Fringe property: The UDO requires a zoning variance for development in areas classified Flood Fringe or Fringe and requires site-plan approval before a building or zoning permit is issued for development in that setting.
• Regulated-drain easement: A fence within a designated regulated-drain easement requires written approval from the Lake County Surveyor under the UDO subdivision provisions.
• Swimming-pool fence: Lake County’s pool requirements establish a separate barrier system for residential swimming pools. The county recognizes a yard fence at least 4 feet high with locking gates, a qualifying fence around the top of the pool, or an automatic-cover alternative under the county checklist.
FENCE PLACEMENT RULES
• Interior side and rear lot lines: In residential zoning districts, a fence or wall may be located along interior side and rear lot lines and within interior side and rear yards, subject to the applicable height, easement, drainage, floodplain, and visibility rules. The UDO does not establish a separate numeric fence setback from those interior side or rear lot lines.
• Street-yard areas: Residential fences and walls may be located in street-yard areas subject to the county’s 3.5-foot maximum height, right-of-way limits, and corner-visibility requirements.
• Street rights-of-way: A fence or wall may not be located within an existing or planned street right-of-way. When the relationship between the proposed fence and the right-of-way cannot readily be determined, the county may require a survey.
• General easements: The UDO makes the property owner responsible for removing and replacing a fence or wall located within an easement when Lake County or a utility provider requires access.
• Drainage easements: A fence or wall placed in a drainage easement may not restrict overland stormwater flow and must maintain at least 2 inches of clearance between the bottom of the fence or wall and the ground.
• Regulated-drain easements: A fence may not be placed within a designated regulated-drain easement without written County Surveyor approval. Indiana regulated-drain law and county drainage administration can also establish a drain right-of-way extending as much as 75 feet from the statutory reference line, subject to reductions and site-specific determinations.
• Corner lots: Corner-lot fence placement is subject to the visibility triangle described in the height and visibility section below. Non-opaque fences receive a specific visibility-band exception, while the separate street-yard height and right-of-way requirements remain applicable.
• Special Flood Hazard Areas: Flood Damage Prevention Ordinance No. 2559 applies to Special Flood Hazard Areas in unincorporated Lake County. The ordinance uses the Lake County Flood Insurance Rate Map and Flood Insurance Study dated January 26, 2023, together with subsequent FEMA updates and specified Indiana Department of Natural Resources flood data. Fence erection within an affected area is floodplain development.
• Floodway and Flood Fringe / Fringe: The UDO prohibits development in mapped Floodway areas. Development in areas classified Flood Fringe or Fringe follows the county zoning-variance and site-plan approval requirements.
• Rural and farm property: Farm fences are expressly recognized in the A-1 zoning district and along farm property lines. They may not be placed in an existing or planned road right-of-way. Indiana agricultural and partition-fence laws can also apply where their statutory land-use conditions are met.
• Indiana 811 before digging: Before covered excavation for fence-post holes, submit an Indiana 811 locate notice. Current Indiana guidance requires notice at least two full working days before excavation, excluding Saturdays, Sundays, and legal holidays, and states that the ticket is valid for 20 calendar days. The owner-or-tenant hand-tool exception is limited to work on that person’s own property at a depth of no more than 12 inches.
FENCE HEIGHT AND VISIBILITY RULES
• Interior side and rear yards: Residential fences and walls may be up to 6 feet high along interior side and rear lot lines and within interior side and rear yards.
• Street yards: Residential fences and walls may be up to 3.5 feet high in street-yard areas.
• Height measurement: Fence height is measured from the average finished grade on the inside of the fence to the top of the fence. When a fence is installed on top of a wall or landscape feature, height is measured from the average finished grade at the base of that wall or feature to the top of the fence.
• Fence posts: Posts may extend up to 12 inches above the highest connected portion of the fence.
• Corner-lot visibility triangle: On a corner lot, the UDO creates a visibility triangle from points extending 20 feet along each street lot line from the lot-line intersection. Within that triangle, the regulated obstruction band extends from 3 feet through 10 feet above the elevation of the street-intersection center point.
• Non-opaque fences in the visibility triangle: The UDO expressly excepts non-opaque fences from the visibility-band obstruction prohibition. The separate 3.5-foot street-yard maximum and right-of-way prohibition continue to apply.
• Hedges and natural plantings: Hedges and natural plantings regulated as barriers are subject to the same location and height rules as fences and walls.
• Pool barriers: When a fence serves as a residential swimming-pool barrier, Lake County’s separate pool requirements call for a yard fence at least 4 feet high with locking gates, unless another qualifying barrier method in the county requirements is used.
• Indiana spite-fence law: Indiana law separately treats a fence-like structure that unnecessarily exceeds six feet and is maliciously erected or maintained to annoy an adjoining owner or occupant as a nuisance. This statewide nuisance provision is separate from Lake County’s zoning height limits.
MATERIAL AND CONSTRUCTION LIMITS
• Wood, Vinyl/PVC, and Chain-link: Lake County’s residential fence provisions do not establish separate material-specific standards for wood, vinyl/PVC, or chain-link. These materials remain subject to the county’s general fence height, placement, visibility, easement, drainage, floodplain, and construction rules.
• Hazardous fence materials in residential districts: Barbed wire, razor concertina, concertina wire, electric fences, and similar hazardous materials are prohibited in residential zoning districts. Agricultural fencing and specialized security fencing are governed by separate provisions where applicable.
• Opacity at corner visibility areas: Non-opaque fences are excepted from the 3-foot-to-10-foot visibility-band obstruction rule within the corner-lot visibility triangle. An opaque fence does not receive that exception. The separate 3.5-foot street-yard height limit remains applicable.
• Fence posts: Fence posts may project no more than 12 inches above the highest connected part of the fence.
• Drainage-easement clearance: A fence or wall in a drainage easement must provide at least 2 inches of clearance above the ground and may not restrict overland stormwater flow.
• Hedges and natural plantings: Hedges and natural plantings regulated as barriers follow the same UDO height and location standards as fences and walls.
• Finished-side, picket-spacing, and ordinary gate standards: The UDO does not establish a countywide residential finished-side orientation requirement, a general picket-spacing standard, or a general gate-swing standard for ordinary fences. Pool gates and other special-purpose enclosures are governed by their applicable requirements.
• Floodplain construction: Within a Special Flood Hazard Area, erection of a fence is regulated as floodplain development and is subject to the applicable floodplain permit, flood-zone, and obstruction provisions. Building-specific elevation and floodproofing standards apply to the types of buildings and structures identified in the flood ordinance.
PRIVATE RESTRICTIONS
HOA covenants, subdivision covenants, deed restrictions, architectural-review requirements, private easements, conservation easements, boundary agreements, and recorded agricultural or partition-fence agreements can impose additional or more restrictive conditions on a residential fence.
Public site constraints operate independently of private covenants. These can include utility or drainage easements shown on a recorded plat, regulated-drain easements administered by the County Surveyor or Drainage Board, street rights-of-way, and mapped floodplain conditions.
A private approval does not replace a required Lake County fence permit, floodplain approval, regulated-drain approval, or Indiana 811 notice. Likewise, issuance of a county permit does not alter an enforceable private restriction that applies to the 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:
• Fence-permit review: Planning & Building may review the proposed fence location and construction for compliance with the UDO and local building-permit requirements. Fence permits are valid for six months.
• Height and street-yard review: Residential fences are subject to the 6-foot interior side/rear maximum, the 3.5-foot street-yard maximum, the right-of-way prohibition, and the county’s fence-height measurement rules.
• Corner-lot visibility: Corner-lot installations are subject to the 20-foot visibility triangle and the 3-foot-to-10-foot obstruction band, including the non-opaque-fence exception.
• Easement and drainage conflicts: Fences in easements remain subject to access requirements, and fences in drainage easements must preserve overland flow and the required two-inch ground clearance.
• Regulated-drain conflicts: A fence in a designated regulated-drain easement requires written County Surveyor approval.
• Floodplain review: Fence erection in a Special Flood Hazard Area is floodplain development under Ordinance No. 2559 and requires the applicable Floodplain Development Permit. Mapped Floodway and Flood Fringe / Fringe areas also carry the UDO restrictions described above.
• Pool-barrier review: A fence used as a swimming-pool barrier is subject to the county’s pool-specific barrier and gate requirements.
• Utility excavation: Fence-post excavation is subject to Indiana 811 requirements when the excavation falls within the state utility-notice law.
• Zoning enforcement: The Lake County Plan Commission administers zoning enforcement in unincorporated Lake County, including violations involving required permits, fence height, placement, visibility, and other applicable UDO standards.
