One of Tennessee's most active new-construction markets — straddling the Williamson–Maury County line, where a parcel's county location determines which fee structure applies. Williamson County parcels carry the $2.00/sq ft Privilege Tax plus Education Impact Fee; Maury County parcels carry the $1.50/sq ft CPRA Development Tax.
Spring Hill is one of the fastest-growing cities in Tennessee and among the most active residential construction markets in the Nashville metropolitan area. With a population approaching 50,000 residents, the city has expanded dramatically since the 1990 opening of the Saturn manufacturing plant — and has continued growing at an extraordinary pace through the 2010s and 2020s, attracting major production builders and a new-construction market anchored by homes averaging approximately $620,000 and 2,700 square feet. Its position along the I-65 corridor, roughly 30 miles south of Nashville, makes it a natural growth point between the Nashville and Columbia–Maury County markets.
The most consequential planning variable for any Spring Hill development project is a straightforward geographic question: which county does the parcel fall in? Spring Hill is the only major city in Middle Tennessee that straddles two county lines — the Williamson–Maury County boundary runs directly through the city. The two counties carry meaningfully different development fee structures. Williamson County parcels are subject to the $2.00 per square foot Privilege Tax plus a tiered Education Impact Fee (up to $12,399 per unit), a combined burden that can exceed $18,000 before city-level charges are added. Maury County parcels, by contrast, carry the county's County Powers Relief Act (CPRA) Development Tax of $1.50 per square foot, enacted effective November 1, 2024 under Resolution No. 08-24-38 — a significantly lower per-permit exposure than the Williamson County side.
At the city level, Spring Hill levies development-related charges on new residential permits. Builders should contact the City of Spring Hill Planning & Development Services directly to confirm current city-level fee schedules before finalizing pro formas, as fee structures are subject to periodic revision in response to Spring Hill's continued rapid growth. County boundary verification — confirming which county a specific parcel falls in before permitting — is among the most important due diligence steps for any Spring Hill development project. The fee calculator below shows city-level charges alongside both Williamson and Maury county fees, so you can compare the total estimated burden for each scenario side by side.

Spring Hill spans two counties — verify your parcel's county location before permitting, as the applicable fee structure differs significantly.
Spring Hill parcels located in Williamson County are subject to two county-wide charges collected by the County Trustee at permit issuance. 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 based on finished square footage, ranging from $1,681 on homes up to 1,399 SF to $12,399 on homes 3,400 SF and above. On a typical Spring Hill home on the Williamson side, these two county fees combined can exceed $16,000 per unit.
Spring Hill parcels located in Maury County are subject to the county's County Powers Relief Act (CPRA) Development Tax of $1.50 per square foot, enacted effective November 1, 2024 under Resolution No. 08-24-38. This replaced the prior $0.50/SF Adequate Facilities Tax (private act) and represents a significantly lower per-permit burden than the Williamson County side. On a 2,700 SF home, the Maury County fee totals $4,050 — compared to over $14,000 for an equivalent home on the Williamson side. Maury County does not levy a separate Education Impact Fee.
Local reporting and public records covering Spring Hill's development landscape, housing market, and county fee policy across Williamson and Maury counties.
Bowen National Research found Williamson County's household count grew 55% between 2010 and 2025 — triple the statewide rate — with a projected shortfall of 10,000+ units by 2030 and a countywide median listing price exceeding $1.3 million.

Read Full ResolutionBy Resolution No. 08-24-38, the Maury County Board of Commissioners voted to replace its longstanding private-act Adequate Facilities Tax with a new County Powers Relief Act development tax of $1.50 per square foot — effective November 1, 2024 — tripling the county's per-SF residential development charge and directly affecting all Spring Hill parcels on the Maury side.
