What happens if you skip the permit (and you needed one)
- St. John code enforcement issues $250–$500 stop-work orders and will require removal of unpermitted fences before you can sell; the citation appears on your property record.
- A fence built in a front yard or corner lot without permit creates a title lien issue — your title company will require proof of removal or retroactive permit ($150–$300 fee) before closing on a sale.
- Pool barriers built without permit trigger insurance denials on liability claims; if a child drowns, your homeowners policy may refuse to pay because the barrier did not meet IBC 3109 spec at time of installation.
- Lenders will not refinance a property with unpermitted fences over 6 feet; you must get retroactive sign-off or remove it, costing $500–$2,000 in labor.
St. John fence permits — the key details
St. John's primary fence rule is found in the local zoning ordinance: fences under 6 feet in rear and side yards are exempt from permitting; fences over 6 feet anywhere on the property require a permit; and ANY fence in a front yard — even 3 feet tall — requires a permit to confirm it does not violate corner-lot sight-distance rules. The sight-line rule is the biggest surprise for homeowners: if your lot is on a corner (including a corner of your own property where a side yard faces a public street), St. John requires 25-foot sight triangles to be maintained so drivers turning onto that street can see oncoming traffic. A fence as short as 30 inches can block this sight line if planted near the corner. The city's building department will ask for a site plan showing the property lines, the fence location, height, and proposed materials. For fences over 6 feet or any masonry, an engineer's footing detail is often requested, especially given St. John's 36-inch frost depth — posts must bottom at least 36 inches below grade, or deeper if soil conditions warrant (the glacial till in this area can shift). Unlike some Indiana municipalities that allow over-the-counter permits for residential fences, St. John typically requires a 1-2 week plan review for front-yard fences and corner-lot fences to confirm setback compliance.
St. John does NOT require a separate electrical or structural permit for wood, vinyl, or chain-link fences under 8 feet. However, if you are installing a pool barrier fence (required by IBC 3109 if the pool is 18 inches or deeper), the fence must be a minimum 4 feet tall with no gaps larger than 4 inches, and any gate must be self-closing and self-latching with a latch at least 54 inches above grade. Pool barrier fences trigger a detailed review and a final inspection before the pool is filled. St. John's building department will also cross-check your application against the local utility company's records (Vectren or Northern Indiana Public Service Company, depending on which utility serves your address) to confirm that no part of the fence is built into a recorded easement; if it is, you will need a written easement modification or relocation. Metal fences on slopes greater than 1:3 may require engineering review as well. The frost depth requirement is non-negotiable: a 36-inch hole in glacial till is labor-intensive, but cutting corners (planting posts only 24 inches deep) is a guarantee of failure inspection and removal in 2-3 years as frost heave pushes posts out of plumb.
Exemptions are narrower than homeowners expect: a like-for-like replacement (same height, same location, same material as an existing fence) is usually exempt IF you can provide proof of the original fence (a photo, or a recorded survey showing the old fence line). If you are upgrading from a 4-foot chain-link to a 6-foot vinyl fence in the same location, you DO need a permit because the height has changed. If you are replacing a 6-foot fence that was grandfathered under old code, St. John will apply current code, so the replacement also needs a permit to confirm compliance. Masonry fences (brick, stone) over 4 feet are always permitted, regardless of location, because they require a foundation and structural review. Wood privacy fences over 6 feet in rear yards are permitted. The gray area: a fence built on a property line. St. John requires the fence to be entirely on your side of the line (typically 6 inches inset to allow neighbor access for maintenance). If you and a neighbor agree to a shared fence, you MUST obtain written easement language and have it recorded; the building department will not issue a permit for a fence straddling the line without it.
St. John's proximity to Lake County and the karst geology to the south creates two unexpected complications. First, if your property is in a recorded flood zone (rare in St. John proper, but common in annexation areas along the Little Calumet River), the fence must not obstruct flood flow, and posts may need deeper footings to prevent scouring. Second, the karst geology (sink-hole prone areas south of St. John) means that if a inspector discovers a pre-existing sinkhole or subsidence, you may be required to relocate the fence or reinforce the footing. This is uncommon but does happen. Third, HOA approval is THE controlling gate: if your subdivision has an HOA, the HOA must approve the fence design, color, and location BEFORE you apply to the city. St. John's building department will request proof of HOA approval on the permit application form. If the HOA denies the fence, the city will not issue a permit, even if the fence meets all zoning and code requirements. This is the single biggest delay we see — homeowners assume the city controls it, only to discover the HOA has an 8-week architectural review board meeting schedule.
The practical process: obtain HOA approval in writing (if applicable); order a property survey or mark property lines with chalk if you know them; measure the fence location and confirm it is at least 6 inches inside your property line; measure the height of the proposed fence; photograph any existing utility lines or easement markers; call or visit St. John Building Department to request the zoning setback requirements for your address and lot type (corner vs interior); file the permit application online if the portal is available, or in person with a site plan showing the fence footprint, height, and material; expect 1-2 weeks for review on corner-lot or front-yard fences, 3-5 days for rear-yard fences under 6 feet; once approved, you can build. Schedule a final inspection once the fence is complete — the inspector will verify height, sight-line compliance (if applicable), and footing depth (for masonry or fences over 6 feet). The footing depth is usually verified by exposing the top of the post hole or using a probe rod. Expect the inspection to take 30 minutes.
Three St. John fence (wood/vinyl/metal/chain-link) scenarios
St. John frost depth and glacial till: why 36 inches matters for fence posts
St. John sits in NRCS climate zone 5A with a frost depth of 36 inches. This means the soil freezes 36 inches below the surface in a typical winter. A fence post set only 24 inches deep (the lazy standard in milder climates) will heave out of the ground in late winter as ice lenses form in the soil, pushing the post up 2-4 inches. By spring, your fence is crooked. By the following winter, the post has shifted enough that the pickets no longer align, and the gate won't close. This is the most common reason fence complaints reach St. John code enforcement: homeowners hire out-of-state contractors who do not understand frost depth and cut corners on digging.
The local soil is glacial till, a dense clay-sand mixture left by the last ice age. This soil is difficult to excavate — you cannot use a hand auger past 2-3 feet; you need a power auger or a backhoe. A contractor unfamiliar with glacial till may bid the job low because they assume easy digging, then realize halfway through that they need machinery, blow the schedule, and either quit or shortcut the hole. The St. John building code explicitly requires that all fence posts be set to a minimum depth of 36 inches or the frost depth, whichever is greater. For masonry fences, the footer must extend to 40-48 inches. St. John's inspectors will probe the footing with a steel rod; if a post is only 24 inches deep, it fails inspection and must be reset.
The solution is to specify in writing to your contractor that all posts must be set 36 inches or deeper, and to request photographic proof during the dig. If you hire a local contractor familiar with St. John work, they will know this rule. If you use a national fence company or a contractor from Florida or Arizona, you must educate them. The permit application itself does not explicitly call out frost depth, but the final inspection will. The added cost of digging 36 inches instead of 24 inches is roughly $5–$10 per post (maybe $200–$500 for a 50-foot fence), but it is the difference between a fence that lasts 15 years and one that fails in 3 years.
HOA approval in St. John: the hidden gate that stops permits
St. John has a high HOA penetration, especially in subdivisions like Ashridge, Schermerhorn, and newer developments north of 93rd Avenue. The surprising rule: the HOA approval must be obtained and submitted with the permit application. St. John's building department will ask for proof of HOA architectural approval on the permit form. If you have not obtained it, or if the HOA denies the fence, the city will not issue a permit. This is not a legal bar (the HOA cannot prevent you from getting a city permit), but it is a practical one — the city's policy is to honor HOA design control and will not override an HOA rejection.
HOA approval is entirely separate from city permitting and follows the HOA bylaws, not the building code. An HOA might reject a fence because the color (white vinyl instead of brown) does not match the subdivision aesthetic, or because the height (7 feet instead of the HOA's allowed 6 feet) exceeds HOA rules, or because the location (too close to the front) violates HOA setbacks that are STRICTER than city code. You must obtain HOA approval first. This adds 4-8 weeks to the timeline if the HOA has a monthly architectural review board meeting; you submit the request, wait for the next meeting, receive a decision (approval or denial with requested changes), revise if needed, and resubmit. Only after HOA approval is in hand can you file the city permit.
The HOA approval letter must be included in the permit packet. St. John's building department will not accept a verbal approval or an email; it must be a formal letter from the HOA board or architectural review committee, signed and dated. If you are unsure whether your property is in an HOA, check your deed or property tax statement, or call St. John's building department — they often know which subdivisions have HOAs. Common HOA restrictions in St. John: no chain-link in front yards, vinyl or wood only; maximum 6 feet in rear yards, 4 feet in side yards, none in front; earth tones (brown, tan, gray) only; no vinyl in historic subdivisions. If your HOA allows a fence and you have written approval, the city will usually issue the permit within 1-2 weeks.

Common questions
Do I need a permit for a fence under 6 feet in my backyard?
If your backyard is a true rear yard (not visible from a public street) and the fence is under 6 feet tall, no permit is required in St. John, assuming it is not a pool barrier and you have HOA approval (if applicable). If your property is on a corner or the side yard faces a public street, any fence — even 3 feet tall — requires a permit to verify sight-line compliance. Call St. John Building Department to confirm your lot type.
What is a corner-lot sight-line requirement, and why does it matter?
St. John requires a 25-foot sight triangle at the corner of your property where two streets meet (or where a side yard faces a public street). A fence, shrub, or other obstruction in this triangle can block drivers' view of oncoming traffic and is a liability and code violation. The city's building department will review the fence location on a site plan to confirm it does not block the sight triangle. This is the reason fences in front yards and on corner lots require permits even if they are short.
How deep do fence posts need to be in St. John?
St. John's frost depth is 36 inches, so all fence posts must be set at least 36 inches below grade. Masonry fences require an even deeper footer (40-48 inches). Posts set only 24 inches deep will heave out of the ground in winter and cause the fence to fail. The final inspection will verify depth, usually with a probe rod. Make sure your contractor understands this requirement before starting the dig.
Is my HOA approval required before I apply for a city permit?
Yes. If your property is in a subdivision with an HOA, you must obtain written HOA architectural approval BEFORE submitting the city permit application. St. John's building department will request proof of HOA approval and will not issue a permit without it. HOA approval is a separate process from city permitting and can add 4-8 weeks if the HOA has quarterly or monthly meetings. Contact your HOA president or architectural review committee to start the approval process.
What is the cost of a fence permit in St. John?
Fence permit fees in St. John typically range from $50–$200, depending on whether it is a simple fence (chain-link, wood privacy under 6 feet) or masonry (which requires engineering review). Exemptions under 6 feet in rear yards incur no fee. Costs rise if a site plan, property survey, or engineer's detail is required (add $300–$800). Always call the building department to confirm the fee for your specific project.
Can I install a fence on the property line, or does it have to be on my side?
Fences must be set entirely on your side of the property line, typically 6 inches inset to allow neighbors access for maintenance. If you and a neighbor agree to a shared fence, you must have a written easement agreement recorded with the county before St. John will issue a permit. Fences straddling the line without an easement will be flagged during inspection and must be relocated, which is expensive and disruptive.
Do pool fences require a different permit process?
Yes. All pool barriers (regardless of fence height or type) require a permit under IBC 3109. The fence must be a minimum 4 feet tall with no gaps larger than 4 inches, and any gate must be self-closing and self-latching with a latch at least 54 inches above the ground. St. John will require a detailed plan review and a final inspection before the pool is filled. Masonry pool fences also require an engineer's footing detail.
What happens if I build a fence without a permit in St. John?
St. John code enforcement will issue a stop-work order ($250–$500 fine) and may require removal of the fence. An unpermitted fence creates a lien on your property and will show up during a title search, blocking refinancing or sale until a permit is obtained retroactively (typically $150–$300 additional fee) or the fence is removed. If the fence is in a front yard or corner lot, the title issue is more severe and can prevent closing entirely.
How long does it take to get a fence permit in St. John?
Rear-yard fences under 6 feet that are exempt from permitting can be built immediately after HOA approval (if needed). Permitted fences (front-yard, corner-lot, over 6 feet, or masonry) typically take 1–3 weeks for review, depending on whether the city requests revisions to the site plan or footing detail. Masonry fences and those requiring engineering may take 2–4 weeks. Always call the building department to ask about current review times.
Do I need a property survey to get a fence permit in St. John?
A full survey is not always required, but St. John typically asks for a site plan showing property lines and the proposed fence location. If you are familiar with your lot lines (from a deed or prior survey), you can mark them yourself. If you are unsure, a property survey ($300–$500) is safer and prevents neighbor disputes or setback violations. For corner-lot fences or sight-line-sensitive locations, a survey is highly recommended.
