One of Tennessee's fastest-growing towns — 30 miles south of Nashville in southern Williamson County — with a layered development fee structure that combines city-level road, parks, and wastewater impact fees with Williamson County's $2.00/sq ft Privilege Tax and tiered Education Impact Fee.
Thompson's Station is a rapidly growing town in southern Williamson County, located approximately 30 miles south of Nashville between Franklin and Spring Hill. From a population of just 2,194 in 2010, the town has expanded to an estimated 9,260 residents in 2025 — a growth rate faster than 98% of similarly sized American cities. This explosive growth has been accompanied by a robust new-construction market, with homes averaging approximately 3,044 square feet and a median sale price of around $800,000. The town's appeal lies in its rolling terrain, preserved rural character, top-ranked Williamson County schools, and convenient access to I-840 and nearby employment centers in Franklin and Brentwood.
For residential developers and homebuilders, Thompson's Station carries a multi-layered development fee structure that requires careful advance planning. At the city level, every new single-family detached permit is subject to a Road Impact Fee of $4,154 and a Parks Impact Fee of $564 per dwelling unit (Ordinance 2023-006), totaling $4,718 in town impact fees alone. A building permit fee of $0.78 per square foot (with a 10% plan review fee on top) also applies to all new residential construction.
In addition to all town-level fees, every Thompson's Station building permit also triggers two Williamson County charges paid directly to the County Trustee at application. The Privilege Tax is a flat $2.00 per square foot of living and expandable space, and the Education Impact Fee is a tiered per-lot charge based on home size — ranging from $1,681 to $12,399 for homes in the full Williamson County Schools district. On a 3,000+ sq ft home, total fees across city and county can readily approach or exceed $24,000, making comprehensive pre-close fee analysis essential.
