Swimming pool permit rules in Williamson County, TN — also covering above-ground pools, in-ground pools, and spa installations — set fencing, barrier, alarm, and inspection requirements.
In unincorporated Williamson County, any pool designed to hold water more than 30 inches deep needs a building permit and must meet zoning setbacks. Pools 30 inches or shallower with no permanent filter or decking are exempt.
Williamson County Zoning Ordinance Section 23.04 defines a regulated swimming pool as any structure, above or below grade, designed to hold water more than 30 inches deep for recreation. Building one in the unincorporated county requires a permit from the Building Codes Department (615-790-5718) and zoning compliance through the Planning Department. Pools are accessory uses that cannot cover more than 20 percent of the lot, and on septic lots the Sewage Disposal Management Department must approve the location. A final inspection is required once the pool is filled and permanent fencing is in place.
Building a regulated pool without a permit is a zoning and building-code violation, subject to a stop-work order, correction, and retroactive permitting. Filling the pool before final inspection is not allowed.
