FENCE RULES – ST. JOHN (TOWN), INDIANA
OVERVIEW
This page applies to residential fence work within the municipal boundaries of the Town of St. John, Indiana. The Town administers its own Unified Development Ordinance and local fence building-permit process. Lake County remains relevant where a property is affected by a county legal drain, while Indiana agencies administer statewide building-code, excavation, floodway, and related requirements that can apply to a particular site.
St. John publishes a direct residential fence rule in its 2026 Unified Development Ordinance. Standard residential fences are generally limited to rear or side yards and a maximum height of 6 feet. Corner lots are treated as having two front yards and use a 10-foot property-line distance plus easement and vision-triangle restrictions. A narrow decorative-front-yard exception allows fencing up to 3 1/2 feet high when it is at least 6 feet from the property line and outside an easement. Wood and vinyl are expressly recognized, while chain-link, barbed-wire, and electrical fencing are prohibited. Current local and state sources were verified in September 2026.
| Quick question | St. John answer |
|---|---|
| Permit or approval | A Town building permit is required to install a fence. The Town also requires a plat of survey and a post-hole inspection. Separate floodplain, floodway, regulated-drain, pool, or other site-specific approvals can apply. |
| Typical fence height | Standard residential maximum: 6 feet. Decorative front-yard fencing: maximum 3 1/2 feet. Pool-barrier fencing has separate special-use requirements. |
| Placement & property lines | Standard fences are in rear or side yards. On a corner lot, the fence must be at least 10 feet from the property line and outside easements and the vision triangle. Decorative front-yard fencing must be at least 6 feet from the property line and outside an easement. Fence post holes must remain within the property lines. |
| Common fence materials | Wood: expressly recognized. Vinyl/PVC: vinyl expressly recognized; PVC is not separately named. Chain-link: prohibited by the current UDO. |
| Important local conditions | Fence rules may be further affected by corner lots, recorded easements, storm-drainage maintenance corridors, mapped floodplain or floodway status, Lake County regulated drains, pool-barrier use, Indiana 811 excavation requirements, new-construction stormwater controls, and private subdivision or HOA restrictions. |

The table above is for quick reference. Additional fence-rule details appear in the corresponding sections below. 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 Town of St. John Building & Planning Department or the responsible office identified for that issue.
GOVERNANCE
The Town of St. John regulates residential fences through Chapter 24, its Unified Development Ordinance (UDO). Ordinance 1883 adopted the current UDO on April 8, 2026. The official code host identifies the code as current through Resolution 2026-06-23. Section 24-45 contains the Town’s dedicated fence standards for residential and commercial lots.
The Town of St. John Building & Planning Department coordinates land-use development, construction permitting, and inspections. For residential fences, the Town publishes a specific building-permit process rather than relying only on a general accessory-structure rule. The Town’s current permit system is Cloudpermit, and Building & Planning remains the local office responsible for fence permit administration and required inspections.
Floodplain administration is a separate Town function under the UDO. The Floodplain Administrator administers development permits in identified special flood hazard areas, and the Town’s floodway provisions coordinate certain floodway work with the Indiana Department of Natural Resources. Town stormwater/MS4 requirements can also apply to individual lots within a permitted development project.
Lake County has a separate county-level drainage role. The Lake County Surveyor, working with the Lake County Drainage Board, manages the county legal-drain system. A St. John property affected by a regulated drain can therefore have a county drainage layer in addition to the Town fence rules. Indiana’s statewide residential building code, Indiana 811 excavation law, and other applicable state rules remain separate from the Town’s local zoning and permit system.
PERMIT AND APPROVAL REQUIREMENTS
St. John publishes a fence-specific local permit requirement. The Town of St. John Building & Planning fence information states that a building permit is required to install a fence and currently lists a $75 fence permit fee.
• Fence permit submittal: The Town requires one copy of the plat of survey showing the proposed fence in relation to the property lines and primary structure, together with a completed building-permit application identifying the contractors who will perform the work.
• Processing and permit placard: The Town states that fence building permits require at least two working days to process. The permit must be paid before issuance, and the permit placard is to be displayed in the window of the primary building where the fence is being constructed.
• Post-hole inspection: A fence requires a post-hole inspection. The inspection is scheduled after the post holes have been dug and before the posts are installed.
• Indiana residential-code permit context: The currently effective statewide residential code is the 2020 Indiana Residential Code, 675 IAC 14-4.4, which adopts the 2018 International Residential Code with Indiana amendments. Indiana deleted model IRC Section R105, so the model-code seven-foot fence work exemption is not an Indiana statewide permit exemption. St. John’s express local fence building-permit requirement governs the ordinary local permit question.
• Special Flood Hazard Area: St. John’s UDO defines development to include the erection of walls or fences. Under UDO Section 24-72 – Floodplain Administration, a floodplain development permit is required before development located wholly within, partially within, or in contact with an identified special flood hazard area. The application is made to the Floodplain Administrator and includes site-development information sufficient to locate the proposed development.
• Regulatory floodway: For work in a regulatory floodway, the UDO states that Indiana Department of Natural Resources approval is required before the local building permit for excavation, deposit, construction, or obstruction activity, unless an applicable general license or exemption applies. The local floodplain development permit cannot be less restrictive than the state floodway approval or applicable exemption criteria.
• New-construction lots within a permitted project: The Town’s Erosion and Sediment Control for Individual Lots Within a Permitted Project – Packet A requires a Declaration of Responsibility, compliance with the permitted project’s erosion-control provisions, stable construction access, perimeter erosion and sediment controls before land disturbance, minimization and cleanup of sediment and tracking, repair and stabilization of disturbed adjacent lots, and final stabilization. Unvegetated areas expected to remain inactive for 15 days or more must be temporarily or permanently stabilized, and vegetated areas with less than 70% density must be restabilized using appropriate methods.
• Individual-lot and one-acre stormwater thresholds: Packet A states that an individual building lot containing less than one acre may be required to complete the Declaration of Responsibility and comply with the Town stormwater ordinance within the local MS4 area. Its typical building-lot detail states that all new construction sites require the applicable MS4 and stormwater erosion-control detail and that a project disturbing one acre or more must obtain the Construction Stormwater General Permit. The packet is directed to individual lots within permitted projects and does not publish a separate fence-specific erosion permit for an ordinary existing-lot fence project.
• Pool-related fence permit: When a separate fence is installed as part of a pool installation, the Town requires a separate fence permit in addition to the pool permit. Above-ground and in-ground pool barriers are subject to the separate construction requirements described below.
• Ordinary zoning/improvement-location approval: St. John does not publish a separate improvement-location permit for a standard residential fence. The fence building-permit process is the ordinary local administrative path, with separate approvals added only when a specific site condition such as floodplain, floodway, regulated-drain, pool, or another applicable rule requires them.
FENCE PLACEMENT RULES
St. John’s fence rule does not publish one universal numeric side- or rear-property-line setback for every residential fence. Instead, it regulates the yard in which the fence may be located, gives separate corner-lot and decorative-front-yard distances, requires post holes to remain within the property lines, and preserves easement, drainage, vision, and other site-specific constraints.
• Ordinary residential location: A standard residential fence must be located in the rear or side yard.
• Corner lots: A corner lot is treated as having two front yards. The fence must be at least 10 feet from the property line and may not be located in an easement or within the vision triangle for road-user safety.
• Decorative front-yard fencing: Decorative fencing may be placed in a front yard only when it is outside an easement and at least 6 feet from the property line. The separate 3 1/2-foot height limit is addressed in the height section below.
• Post-hole location: The Town’s permit guidance states that all fence post holes must be located within the property lines. A curb, sidewalk, ditch, mowing line, tree line, existing fence, or online mapping line does not establish the legal property boundary.
• Designated easements: Town permit guidance states that if a fence is placed on a designated easement and utility work later requires access, the property owner is responsible for removing the fence and replacing it at the owner’s expense. Corner-lot fences and decorative front-yard fences are more restrictive because Section 24-45 expressly bars them from easements.
• Storm-drainage ditches and channels: Under UDO Section 24-87 – Open Watercourse, access to storm-drainage ditches and channels is provided by maintenance easements at least 20 feet wide on each side, measured horizontally from the top of bank and exclusive of the ditch or channel width. Those maintenance easements must be kept free of obstructions. A fence affecting such an easement must comply with that obstruction-free maintenance requirement.
• Lake County regulated drains: The Lake County Surveyor and Drainage Board administer the county legal-drain system. Indiana regulated-drain law can create a statutory right-of-way that may extend up to 75 feet from the centerline of a tiled drain or the top of bank of an open drain, subject to statutory reductions and site-specific determinations. A permanent structure may not be placed in a regulated-drain right-of-way without the required drainage-board consent. This is a parcel-specific drainage condition, not a universal St. John fence setback.
• Roads and rights-of-way: Section 24-45 does not publish a separate universal residential fence setback from every road right-of-way. Property-line, easement, drainage, and vision requirements still apply, and state-highway or other public right-of-way controls may add separate restrictions where the property actually adjoins such a corridor.
• Indiana 811 before digging: Before covered fence-post excavation, the homeowner or excavator must submit a locate request through Indiana 811 / Indiana Utility Regulatory Commission excavation guidance. Indiana treats planting or removing fences and fence posts as excavation. Utilities have two full working days, excluding Saturdays, Sundays, and legal holidays, to mark underground facilities, and a locate ticket is valid for 20 calendar days. A property owner or tenant using only hand tools on the person’s own property at a depth of 12 inches or less falls within the limited statutory exception; deeper digging, powered excavation, contractor work, or other covered excavation requires the normal locate process.
FENCE HEIGHT AND VISIBILITY RULES
St. John uses a straightforward ordinary residential height limit with a separate front-yard decorative-fence exception. Corner-lot visibility is an additional placement condition rather than a different general height maximum.
• Standard residential fence: Maximum height is 6 feet.
• Corner lot: The 6-foot residential maximum remains applicable, but a corner-lot fence must also be at least 10 feet from the property line and outside the easement and vision triangle.
• Decorative front-yard fence: Maximum height is 3 1/2 feet. The fence must also be outside an easement and at least 6 feet from the property line.
• Vision triangle: Section 24-45 prohibits a corner-lot fence within the vision triangle. The fence section does not publish a dimensional formula for the vision triangle.
• Above-ground pool barrier: Town pool guidance requires fencing at least 5 feet and not more than 6 feet high for the stated above-ground pool barrier method. This is a pool-specific safety rule, not the minimum height for an ordinary residential fence.
• In-ground pool or spa barrier: Town guidance allows an approved ASTM F1346 safety cover or a 6-foot fence that completely surrounds the in-ground pool or spa. This is a special pool-barrier branch and does not change the ordinary 6-foot residential maximum.
MATERIAL AND CONSTRUCTION LIMITS
St. John’s current UDO names the principal residential fence materials directly and also publishes three categorical material prohibitions. The material rule applies in addition to the yard, height, easement, corner-lot, pool, and other site-specific requirements.
• Wood: Expressly recognized as a fence material.
• Vinyl/PVC: Vinyl is expressly recognized. PVC is not separately named by the UDO.
• Aluminum: Expressly recognized.
• Wrought iron: Expressly recognized.
• Similar-style material: The ordinance also recognizes a ‘similar style material’ category. It does not publish a separate residential approval list for every possible material within that category.
• Chain-link: Prohibited by the current UDO.
• Barbed wire: Prohibited by the current UDO.
• Electrical fencing: Prohibited by the current UDO.
• Decorative front-yard construction: The UDO defines the qualifying front-yard fence as ornamental, aesthetic, and designed to enhance the beauty of the property; it may incorporate decorative elements or designs. The 3 1/2-foot height, 6-foot property-line distance, and easement restrictions also apply.
• Ordinary residential construction details not separately specified: Section 24-45 does not publish separate ordinary residential rules for finished-side orientation, opacity, picket spacing, post caps, composite, masonry, bamboo, corrugated materials, razor/concertina wire, or similar unlisted construction details. Other Town provisions or special-use rules can still govern when a fence serves a different regulated function.
• Above-ground pool barrier construction: Town guidance requires the fence to completely surround the pool and deck area and to be immediately adjacent to the pool walls. It must include both a self-closing and latching gate capable of being locked when the pool is not in use, and the fencing must be in place before final inspection.
• In-ground pool or spa barrier construction: If the pool or spa uses a fence rather than an approved ASTM F1346 safety cover, Town guidance requires a 6-foot fence completely surrounding the pool or spa and a gate capable of being locked when the pool or spa is not in use. The Town’s published guidance states that the gate is to be self-closing or latching. Pool barriers must also comply with the applicable Indiana residential-code requirements identified by the Town.
PRIVATE RESTRICTIONS
HOA covenants, private subdivision restrictions, deed restrictions, architectural-review covenants, recorded private easements, boundary agreements, agricultural agreements, recorded partition-fence agreements, conservation easements, and other private instruments operate independently from St. John’s public fence requirements and may be more restrictive.
The Town’s fence guidance specifically directs property owners to review the covenant agreement associated with the deed for subdivision-specific rules and states that those rules are enforced by the developer or homeowners association separately from Town requirements. Private restrictions should also be distinguished from public utility or drainage easements, regulated-drain rights-of-way, floodplain controls, and other governmental requirements that can affect the same part of a 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: Building & Planning can review the plat of survey, fence location, height, material, corner-lot conditions, easements, and other UDO requirements before the local fence building permit is issued.
• Post-hole inspection: The Town requires inspection after the holes are dug and before the posts are installed. This creates an inspection point for the approved fence location before the fence is completed.
• Height, yard, and material compliance: The 6-foot residential maximum, rear/side-yard rule, 3 1/2-foot decorative-front-yard exception, corner-lot conditions, and prohibitions on chain-link, barbed-wire, and electrical fencing can become enforcement issues when a fence does not match the current UDO.
• Floodplain or floodway review: A fence that qualifies as development in an identified special flood hazard area is subject to the local floodplain development-permit framework. Regulatory-floodway work can also require Indiana Department of Natural Resources approval or evidence of an applicable general license or exemption before local permit action.
• Storm-drainage maintenance easement: A fence affecting a storm-drainage ditch or channel can be reviewed against the UDO requirement for obstruction-free maintenance easements at least 20 feet wide on each side measured from the top of bank.
• New-construction erosion control: On an individual lot within a permitted project, the Town’s Packet A assigns erosion and sediment-control responsibilities, including pre-disturbance perimeter controls, sediment/tracking cleanup, temporary stabilization for qualifying inactive areas, and final stabilization. Projects disturbing one acre or more are also identified as requiring the Construction Stormwater General Permit.
• Lake County regulated-drain review: A parcel affected by the county legal-drain system can be subject to Lake County Surveyor and Drainage Board requirements in addition to Town fence rules.
• Pool-barrier review: When a fence serves as an above-ground or in-ground pool barrier, the separate Town permit, height, enclosure, gate, and final-inspection requirements apply.
• Indiana 811 excavation: Fence-post digging is covered excavation unless a narrow statutory exception applies. The locate process remains separate from the Town fence permit, property-line determination, easement restrictions, drainage review, floodplain review, and private covenants.
