Williamson County's county seat and one of Tennessee's wealthiest, most desirable cities — 21 miles south of Nashville, with one of the most complex development fee structures in the state: a $2.00/sq ft county Privilege Tax plus a tiered Education Impact Fee that together can exceed $20,000 on a single new-home permit.
Franklin is the county seat of Williamson County — consistently ranked among the highest-income counties in the United States — and one of the most sought-after residential destinations in the entire Nashville metropolitan area. Located approximately 21 miles south of downtown Nashville, Franklin has grown from a small Civil War–era market town to a city of over 92,000 residents (December 2024 estimate per the City of Franklin's own Development Report), with projections reaching approximately 103,000 by 2030. The city is known for its nationally recognized downtown historic district, top-ranked schools, high household incomes (median approximately $119,500), and a new-construction market averaging approximately $875,000 and 2,600 square feet.
For residential developers and homebuilders, Franklin carries one of the most layered development fee environments in Middle Tennessee — combining both city-level fees and county-wide charges on every new permit. At the city level, Franklin levies a Road Impact Fee — tiered by unit size and updated by Ordinance 2023-41, reaching up to $19,514 per unit for large detached homes at the January 1, 2026 rate — and a Parkland Impact Fee assessed per dwelling unit to fund parks and green space expansion proportional to growth. On top of these city charges, every permit is also subject to Williamson County's Privilege Tax of $2.00 per square foot of living and expandable space, plus a tiered Education Impact Fee that scales with home size and school district location.
A critical variable for Franklin developers is the Franklin Special School District (FSSD). FSSD operates its own K–8 schools within Franklin city limits. Because FSSD educates students through 8th grade, homes inside FSSD boundaries pay only the high school component (Grades 9–12) of the Williamson County Education Impact Fee — a meaningfully lower charge than the full K–12 rate that applies to projects outside FSSD. On a 3,400+ sq ft home, this distinction means the Education Impact Fee drops from $12,399 (outside FSSD) to $4,877 (inside FSSD). Combined with the city's Road Impact Fee and Parkland Impact Fee, confirming a parcel's FSSD boundary status and city fee exposure before closing is among the most consequential due diligence steps for any Franklin development project.

Every Franklin building permit 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, split equally between the Adequate Facilities Tax and the Adequate School Facilities Tax. The Education Impact Fee is a tiered per-lot charge — with a critical variable: homes inside the Franklin Special School District (FSSD) pay only the Grades 9–12 component ($602–$4,877), while homes outside FSSD pay the full K–12 rate ($1,681–$12,399). Verifying FSSD boundary status before closing is one of the most consequential due diligence steps in any Franklin pro forma.
