Maury County Land Investment Growth Despite Higher Development Taxes

According to tnimpactfees.com, on November 1, 2024, Maury County tripled the development tax attached to every new residential building permit, from fifty cents a square foot to a dollar fifty. That kind of increase usually cools a market. Builders who had spent years treating the county as the discount alternative to Williamson County's fee schedule kept pulling permits anyway. That is the part of the Maury County growth story that gets skipped when the conversation jumps straight to the GM battery plant.

The easy explanation is the one most people already know. Ultium Cells committed $2.3 billion to a battery plant in Spring Hill in 2021, added another $275 million to that investment later, and is building toward a workforce of 1,700. That money is real, and it did pull people south along I-65. But a battery plant twenty-some miles away does not explain why a developer would pick a parcel in downtown Columbia over a comparable site in Williamson County. Fees and zoning explain that. Jobs explain population growth. Those are two different questions, and land investors who conflate them tend to misprice both sides of the county line.

What Actually Moved Bristol Development Group

Bristol Development Group is building The Drake, a mixed-use project in downtown Columbia pairing residential units with bakeries, coffee shops, and retail space. When the company laid out its reasoning for the site, it did not point to Ultium or Spring Hill's manufacturing jobs. It pointed to Williamson County's impact fees and what it described as increasingly restrictive zoning, and said those two conditions pushed the project south into Maury County instead.

That is a specific, dated example of a builder doing the math and choosing Columbia on cost and process grounds, not proximity to a factory. It is worth sitting with, because it means the growth Maury County is experiencing right now is being shaped as much by what Williamson County's planning commission does as by anything happening at the Ultium campus.

The Fee Math That Still Favors Maury County, For Now

Here is what a builder is actually working with on the Maury County side of a residential permit today:

• A city of Columbia building permit fee of $0.60 per square foot of space under roof, covering plumbing, gas, and mechanical work
• A 25 percent plan-checking fee layered on top of any permit that requires plan review
• Maury County's Development Tax of $1.50 per square foot, collected by the county Building and Zoning Office on every new residential permit

The $0.60 city permit fee and $1.50 county tax total roughly $4,200 for a 2,000-square-foot home, before any applicable plan-checking fee and before a foundation is poured. That $1.50 county rate is triple what it was before November 2024, when the private-act adequate facilities tax sat at $0.50 per square foot. The county raised it under a specific resolution, and the timing matters. Anyone who priced land in Maury County based on pre-2024 fee assumptions is working from a number that no longer exists.

There is no single public figure I can point to for a directly comparable Williamson County fee total, and I would rather say that plainly than guess at one. But Bristol Development Group's own stated reasoning, choosing Maury County specifically because Williamson County's fees and zoning were harder to work with, tells you the gap was wide enough in 2025 to move a real project with real capital behind it. The open question for anyone underwriting a deal today is how much that gap has narrowed since Maury tripled its own tax, and whether Williamson County's rules have shifted in the meantime too. Maury County's Building and Zoning Office was still meeting on its comprehensive plan advisory committee as recently as May 2026, which means the rules Bristol built around have not finished settling.

What the Price Data Actually Shows

Maury County's median sale price reached $439,000 in March 2026, up 2.5 percent from a year earlier, with 197 homes sold that month compared to 166 the year before. Time on market stretched too, from 95 days to 114. That is a market absorbing meaningfully more inventory, not one riding a straight appreciation line. More homes are selling, but they are sitting longer to do it.

Columbia itself tells a quieter version of that story. Zillow's home value index for the city put the average at $374,557 as of April 2026, up only about 1 percent year over year, a much flatter read than the county-wide sale price figure. That gap is not a contradiction. Spring Hill's newer subdivisions, closer to the Ultium campus, pull the county median higher. Columbia's downtown, the part of the county actually absorbing projects like The Drake, is moving at a slower, steadier pace than the county headline number suggests. If you are pricing land near downtown Columbia specifically, the county-wide figure will mislead you in the direction of optimism.

What This Means If You're Holding Land on Either Side of the County Line

For anyone weighing acreage or a development play near the Maury-Williamson border, the temptation is to treat Maury County's cost advantage as a fixed feature of the map, something as permanent as the interstate exit. It is not. It is a policy spread between two counties, and policy spreads move. Maury County just moved its half of that spread by tripling its own tax. Williamson County's zoning posture is the other half, and it is set by a planning commission, not by geography.

If you inherited land near that line, or you are sitting on acreage and deciding whether to hold, sell, or bring a builder to the table, the useful question is not whether Maury County is growing. It obviously is. The useful question is how wide the fee and zoning gap is this quarter, who last voted to change it, and what that means for what a builder will actually pay to develop your specific parcel versus one twenty minutes north. That is a conversation worth having before a listing goes up or an offer gets signed, not after.

Frequently Asked Questions

Is Maury County still cheaper than Williamson County to build in?

Based on the fee schedule and Bristol Development Group's own public reasoning, yes, as of 2025 and into 2026. But the gap narrowed sharply when Maury County tripled its development tax on November 1, 2024, and neither county's rules are static. Anyone underwriting a project should confirm current fee schedules directly with the Maury County Building and Zoning Office and Williamson County's planning department rather than relying on a figure that might already be a year or two stale.

Does the Ultium Cells plant directly affect land values in downtown Columbia?

It affects Spring Hill and the rooftops built to house its workforce more directly than it affects downtown Columbia. Projects like The Drake are responding to the fee and zoning gap between counties more than to plant proximity. The two forces are related, since Ultium's jobs are part of what makes Maury County attractive enough for that gap to matter, but they are not the same driver, and treating them as interchangeable will lead to mispricing land depending on which part of the county you are actually looking at.

If you are holding acreage near the Williamson-Maury line, or you are trying to figure out what a parcel is actually worth once fees and zoning are priced in on both sides, I have spent three decades working land, estates, and complicated ownership situations across this part of Middle Tennessee.
