Quick answer
Williamson County's Zoning Ordinance and Swimming Pools brochure both describe fencing standards required around swimming pools, a minimum 4-foot self-latching fence under Section 11.04(D)(13), but this is a zoning safety requirement tied to pool permitting, not a standalone fence permit. No Building Codes Department page or document states whether building a residential fence unrelated to a pool requires its own permit in unincorporated Williamson County. Contact the Building Codes Department at 615-790-5718 or the Planning Department at 615-790-5725 to confirm.

What a fence permit costs in Williamson County
How Williamson County compares in Tennessee
No Tennessee jurisdiction we have verified sets a size threshold for this permit, so what actually differs between them is the fee.
How to apply in Williamson County
In Williamson County, 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 Williamson County, 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 Williamson County, 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 Williamson County, 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 Williamson County, 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 Williamson County: 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 Williamson County: 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 Williamson County: 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 Williamson County: 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 Williamson County: 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 Williamson County: 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 Williamson County permit portal or by phone at 615-790-5718.

- You can apply through the Williamson County permit portal or contact the Williamson County Building Codes Department directly. The links are listed on this page.
- Can a homeowner pull a fence permit themselves in Williamson County?
- Under Tennessee law (T.C.A. 62-6-103; Tenn. Comp. R. & Regs. 0780-02-23-.01(1)(i), -.05(3), -.05(4)(b)2.; Tenn. Comp. R. & Regs. 0780-02-01-.05(2)(a)): Tennessee lets a homeowner act as their own builder. Under T.C.A. 62-6-103, as the State Fire Marshal's Office explains it, an owner may construct a single residence once every two years for personal use without a contractor's license, so long as the home is not for resale, lease, or rent, and anyone the homeowner hires whose portion of the work is $25,000 or more must be a licensed contractor. In state permit areas the owner pulls a property owner's permit, limited by rule to one per 24 month period, and the work is subject to the same inspections and fees as a contractor's job; proof of licensure is waived at permit purchase only when the owner personally performs the work. For electrical work, a homeowner may wire their own residence only after obtaining a residential property owner's electrical permit, which covers only the applicant and immediate family, does not authorize help from anyone unlicensed, and is limited to one per 12 month period unless the owner lost the home to fire or windstorm. Confirm how Williamson County applies this before you apply.
