One of Tennessee's fastest-growing counties south of Nashville — anchored by a booming Spring Hill auto corridor and a development fee environment that is actively evolving under state legislative pressure.
Maury County is home to an estimated 115,000 residents as of 2024 — making it one of Tennessee's fastest-growing counties over the past decade — with population growth fueled primarily by its position along the I-65 corridor south of Nashville. The county seat of Columbia anchors the southern end of the market, while Spring Hill — straddling the Maury-Williamson County line — has emerged as one of the region's most active residential construction markets.
The county contains approximately 47,800 housing units, with the median home value standing near $390,000 as of 2024. New construction activity is concentrated in and around Spring Hill, where builders have delivered thousands of units over the past several years to meet demand from workers relocating for jobs at the General Motors Spring Hill Assembly Plant and a growing base of Nashville-area employers. The average single-family home in the county spans approximately 2,100 square feet.
Maury County's development fee environment underwent a significant structural change effective November 1, 2024. By Resolution No. 08-24-38, the Maury County Board of Commissioners voted to cease its longstanding Adequate Facilities Tax — a private act privilege tax authorized under Chapter 118 of the Private Acts of 1991, capped at $0.50 per square foot for residential development — and replace it with a new tax on development levied under the County Powers Relief Act (T.C.A. § 67-4-2901 et seq.), as amended by Public Chapter 990 of 2024. To qualify, the county filed a population growth statement with the Tennessee Comptroller confirming 24.72% growth from 2010 to 2020 (80,956 to 100,974 residents), which was verified and approved. The new tax is assessed at $1.50 per square foot for residential development and $1.50 per square foot for non-residential development up to 150,000 square feet per structure — a rate three times higher than the previous cap and one of the most significant development fee increases in Maury County history. Builders with permits issued prior to October 31, 2024 are subject to the old AFT structure; all permits issued on or after November 1, 2024 are subject to the new County Powers Relief Act rate.

Local reporting and public records covering Maury County's development fee landscape, housing growth, and legislative activity.
Maury County joined Rutherford, Wilson, Williamson, and Montgomery counties in backing House Bill 2426, which would have allowed counties to raise their adequate facilities tax rates by up to 50% immediately and by up to 10% every four years thereafter. The bill stalled in committee amid opposition from the Tennessee Realtors Association and the Home Builders Association of Tennessee.
Read MoreMaury County Schools officials have pointed to rapid residential growth — particularly in the Spring Hill corridor — as a primary driver of school capacity shortfalls. With the $5,000 flat AFT generating limited revenue against a backdrop of escalating construction costs, school leaders have called for state authorization to increase the rate and dedicate more revenue to school capital projects.
Read MoreSpring Hill — which straddles the Maury-Williamson County line — continues to attract major national builders including D.R. Horton, NVR, and Meritage Homes. The city's location along I-65 and proximity to the GM Spring Hill Assembly Plant have sustained demand, while the relatively straightforward county fee structure compared to Williamson County keeps pro forma costs competitive for builders targeting the mid-$300K to $500K price range.
