If you’re planning to install a new fence around your property in St. Louis, you might be tempted to skip the paperwork and just get started. But before you dig a single post hole, it’s worth knowing that most fence installations in St. Louis require a permit, and skipping that step can lead to fines, forced removal, or headaches when you go to sell your home.
This guide walks you through exactly what you need to know: when a permit is required, how to apply, what to expect during the process, and how to avoid the most common mistakes homeowners make.
Do You Need a Fence Permit in St. Louis?
The short answer: probably yes. Whether you’re located in the City of St. Louis or St. Louis County, most new fence installations require a permit . However, the rules vary depending on your specific municipality.
General triggers that require a permit include:
- Fences over a certain height (typically 4–6 feet, depending on location)
- Fences installed in front yards
- Fences on corner lots with visibility triangle rules
- Fences near utility easements or flood zones
Some smaller repairs or replacements of existing fence sections may be exempt, but it’s always best to check with your local building department before assuming you’re in the clear.
Pro tip: If you live in an unincorporated part of St. Louis County, your rules come from St. Louis County’s Department of Public Works. If you’re within a municipality like Chesterfield, Kirkwood, or Webster Groves, check with that city directly; each has its own code.
Step 1: Check Your Local Zoning and HOA Rules
Before you contact the building department, take two important preliminary steps:
Check your zoning district. Zoning regulations dictate where fences can be placed on your lot, how tall they can be, and what materials are allowed. Residential zones often have stricter limits than commercial ones.
Review your HOA guidelines. If you live in a subdivision governed by a homeowners association, your HOA may have its own approval process that runs parallel to, not in place of, the city permit process. Some HOAs require specific fence styles, colors, or materials to maintain neighborhood aesthetics.
Skipping either of these steps is one of the most common (and costly) mistakes property owners make.
Step 2: Gather Your Documents
Once you’ve confirmed a permit is needed, you’ll need to pull together a few key items before submitting your application:
- Site plan or plot survey – Shows your property boundaries, existing structures, and the proposed fence location. Your mortgage documents may include a survey; if not, you may need to commission one.
- Fence specifications – Height, material (wood, vinyl, aluminum, chain-link), and style of the fence.
- Setback measurements – The distance between the fence and your property lines, sidewalks, and easements.
- Contractor information – If you’re hiring a professional Fence Builder In St. Louis, MO, you’ll typically need their license number and contact information on the application.
Having these documents ready before you apply will save you significant time.
Step 3: Submit Your Permit Application
For most residents, the application can be submitted in one of three ways:
- Online – St. Louis County and many municipalities now offer online permitting portals. This option offers the quickest and most convenient solution .
- In person – Visit your local building and development services office. Bring all documents listed above.
- By mail – Some jurisdictions still accept mailed applications, but processing times are slower.
Permit fees for residential fences in the St. Louis area typically range from $50 to $200, depending on the jurisdiction and the scope of the project. Larger or more complex installations may carry higher fees.
Processing times vary. Simple residential permits in St. Louis County may be approved in as little as 2–5 business days through the online portal, while more complex applications or those requiring zoning review can take 2–4 weeks.
Step 4: Wait for Approval Before You Build
This is where a lot of homeowners get impatient and get into trouble. Do not start construction before your permit is approved. Building without a permit (or before approval arrives) can result in:
- Stop-work orders
- Fines ranging from $100 to $1,000 or more
- Mandatory removal of the fence at your own expense
- Complications during property sale inspections
Once your permit is approved, you’ll typically receive a permit placard or number that should be kept accessible at the job site during construction.
Step 5: Schedule Any Required Inspections
Depending on your municipality, a fence installation may require one or more inspections:
- Pre-construction/footing inspection – Verifies post hole depth and placement before concrete is poured.
- Final inspection – Confirms the completed fence matches the approved plans.
Your permit paperwork will indicate which inspections are required and how to schedule them. If you’re working with a licensed contractor, they should handle inspection scheduling as part of their service.
Common Mistakes to Avoid
Even well-intentioned homeowners run into problems. Here are the most frequent pitfalls:
Assuming your neighbor’s fence is on the property line. Many disputes arise when a homeowner builds “where the old fence was,” only to discover it was incorrectly placed. Always verify your property lines with an official survey.
Ignoring utility easements. Fences cannot be placed over underground utility lines or within certain setback distances from easements. Call 811 (Missouri’s “Call Before You Dig” service) before any digging begins; it’s free and required by law.
Choosing the wrong contractor. An experienced, licensed Landscaping Services in St Louis, MO provider or fence contractor will be familiar with local permit requirements and can often pull the permit on your behalf, saving you time and stress.
