What Are Tennessee Impact Fees?
Tennessee growth charges flow through the County Powers Relief Act (Tenn. Code Ann. § 67-4-2901 et seq.), which lets qualifying high-growth counties levy school facilities taxes, alongside older private-act impact fees and adequate facilities taxes in middle Tennessee, plus utility tap and capacity fees statewide.
The Nashville ring — Williamson, Rutherford, Wilson, Sumner — carries the state's heaviest per-home charges. Tennessee figures on impactfees.org are model estimates for early comparison; county facilities taxes and private acts differ materially, so verify locally.
Tennessee figures are illustrative estimates from our statewide cost model — calibrated to local construction costs and community size — rather than verified fee schedules. Use them for early budgeting and site comparison, and see our methodology for how estimates are built.
