Fence Permit in St. Louis, Missouri

Sometimes, depending on the project

Quick answer
The City of St. Louis is an independent city, not part of St. Louis County, and the two run completely separate building departments, so a St. Louis County or Clayton permit page does not apply to an address inside the city and vice versa. The City Building Division requires a building permit for "all new fences of any type", with one exemption: replacing an existing fence at the same height, material and location. Title 25 of the Revised Code narrows that exemption further, withdrawing it when the fence encloses a swimming pool, hot tub or spa. In a City Historic District or at a City Landmark, all fences also need Cultural Resources Office approval even where the Building Code alone would not require a permit.

What a fence permit costs in St. Louis
How to apply in St. Louis
In St. Louis, most residential fences fall under the model code's 7-foot building-permit exemption, so the real approval step is a lightweight zoning or land-use permit built around a simple site plan showing the fence's location, height, and material, checked against setbacks and any corner-lot sight-triangle rule. A fence that will serve as a required swimming-pool barrier is the exception, since barrier fences carry life-safety requirements of their own.
What most fence permit applications include:
- For St. Louis, a fence 7 feet or under is exempt from the model code's building permit, the same threshold the IRC uses for other small projects (IRC 2021 R105.2).
- That exemption only removes the building-code permit. It does not authorize skipping a jurisdiction's own zoning approval, which is why an exempt fence can still need its own land-use or zoning permit rather than a building permit (IRC 2021 R105.2).
- Whatever your jurisdiction calls that approval, the application centers on a basic site plan: a drawing of the property showing the fence's location, height, and material, and how it relates to the property lines (common local zoning practice).
- For St. Louis, the same plan is checked against required setbacks and, on corner lots or near intersections, a sight-triangle rule that caps fence height so it does not block sightlines for drivers (common local zoning practice).
- For St. Louis, a fence that will serve as a required swimming-pool barrier is handled as life-safety work rather than the light zoning process, and at least one state's adopted residential code requires a building permit for barrier fences regardless of the general fence exemption (Oregon Residential Specialty Code 2021, R101.2.2).

Inspections and closing out your permit
In St. Louis, inspection follows the permit: a fence that never needed one gets no inspection at all under the model code, and a permitted fence typically gets a single final check rather than the staged inspections used for a house. The exception is a fence serving as a swimming-pool barrier, which gets its own dedicated barrier inspection covering height, gaps, and gate hardware.
- In St. Louis: inspection duty attaches only to work for which a permit is required, so a fence that qualified for the permit exemption carries no inspection obligation under the model code (IRC 2021 R109.1).
- In St. Louis: where a fence permit was issued, the process skips the staged foundation, frame, and rough-in inspections used for buildings and goes straight to one final inspection once the fence is finished (IRC 2021 R109.1.6).
- In St. Louis: that single check is typically a zoning compliance inspection rather than a structural review, confirming the fence matches the approved height and site plan (common local practice).
- A fence built as a swimming-pool barrier breaks that light-touch pattern in St. Louis: it is separately inspected for barrier compliance, commonly required before the pool itself can be signed off (ISPSC 305; local pool-barrier inspection programs).
- In St. Louis: that barrier inspection checks dimensional rules from the swimming pool and spa code rather than ordinary fence rules, including the minimum 48 inch barrier height and limits on openings and gaps a young child could pass through (ISPSC 305).
- Gate hardware is inspected too in St. Louis: a self-closing, self-latching gate is part of the barrier requirement, since an unlatched gate defeats the fence's purpose as a barrier (ISPSC 305).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the St. Louis permit portal or by phone at (314) 622-3313.

- Where do you apply for a fence permit in St. Louis?
- You can apply through the St. Louis permit portal or contact the City of St. Louis Building Division, Permit Section (Department of Public Safety) directly. The links are listed on this page.
- Can a homeowner pull a fence permit themselves in St. Louis?
- Under Missouri law (RSMo 701.055.1 and 701.055.2; RSMo 327.101.2(5)(a); RSMo 327.191.2(5)(a); RSMo 700.656.5): Missouri does not license general contractors at the state level and has no statewide owner-builder permit statute, disclosure affidavit, or resale restriction comparable to Florida's one year rule. Whether a homeowner may pull the permit and do the work is decided by the city or county that issues the permit. Where state law does speak, it is permissive: RSMo 327.101.2(5)(a) and RSMo 327.191.2(5)(a) let an unlicensed person render architectural and engineering services for the construction, remodeling or repair of a privately owned dwelling house, provided the drawings say the person is not licensed, so plans for a house do not have to be sealed by an architect or engineer. RSMo 701.055.1 expressly preserves a property owner's right to install, modify or repair their own on-site sewage disposal system as long as the state standard is met, and RSMo 701.055.2 adds that no permit or contractor registration is required simply to clean it. RSMo 700.656.5 exempts a person who installs a manufactured home on his or her own property for his or her own occupancy from the otherwise mandatory state installer license. None of these exemptions excuses a local permit where the local jurisdiction requires one. Confirm how St. Louis applies this before you apply.
