Gallatin Rewrote Its Zoning Code This Fall. Not Everything in the Listing Survives the Sale.

In Gallatin, the sale itself now changes what a property can do. The city's new zoning ordinance, which Gallatin calls ZoCo, took effect September 1, 2026. Under it, a short-term rental that was operating legally before that date can keep operating only until the property sells. Development applications filed under the old rules get one year to finish under those rules. And acreage designated in a new rural overlay that is developed under the overlay's rules must be built in clusters, with at least half the site permanently preserved. In all three cases, the listing describes what the current owner can do. Some of that ends when the buyer takes title.

ZoCo is the city's first comprehensive zoning update since 1998. Gallatin News reported that the City Council gave the ordinance and its zoning map final approval at its Tuesday, September 1 meeting, with a unanimous vote after a second reading with amendments. Under Section 1.3.1, the effective date is the date the ordinance was passed and adopted.

The Rental Income Stops at the Closing Table

The sharpest change for buyers is in Article 9, the section on uses. An existing short-term rental that was operating before September 1, 2026, consistent with Tennessee's short-term rental statute at T.C.A. §13-7-601 through 606, may continue under the new code. That protection belongs to the current owner, and the adopted text of Article 9 says what happens next:

"Upon sale of the property, the owner/operator shall notify the City of the sale of such property and operation as a Short-Term Rental Unit(s) shall terminate."

This matters most when a listing describes rental history, bookings or projected income. That income came from a use that, under the ordinance's wording, ends when the property sells. A buyer who wants to keep renting the home short-term is starting over as a new operator under the new rules.

Those rules apply to every operator. For starters, every owner or operator, including those with units that existed before the ordinance, must register the rental's location and address with the City. Registering a pre-existing unit is not grounds to deny the right to keep operating it. Beyond registration, an operator must:

1. Get a City permit, pay the business tax, and renew both every year.
2. Pass a Fire Marshal inspection before the first guest arrives, and again each year when the business tax is renewed.
3. Name a caretaker or local contact who is available 24 hours a day, seven days a week, can physically respond within one hour of an emergency or complaint, and can take action to resolve it. That person may be the owner, the lessee, or the owner's agent.
4. For units established after September 1, 2026, provide proof of insurance, limit occupancy to two people per bedroom with a cap of 12, meet a 140-square-foot minimum bedroom size with an attached closet, provide hard-surfaced or dust-free gravel parking, and rent for no less than 24 continuous hours.

The ordinance also says short-term rentals are permitted in certain residential, mixed-use and commercial districts "unless restricted by private covenants or deed restrictions." So the zoning district is one check and the subdivision's covenants are another.

A Filed Plan Comes With a Deadline

The same principle applies to land. When a parcel comes to market with a development application already filed with the City, it is easy to assume the buyer is getting that approval path along with the dirt. Under ZoCo, pending applications keep the chance to be completed, reviewed and acted on under the ordinance in effect when they were submitted. That chance expires "one (1) year from the Effective Date."

With an effective date of September 1, 2026, the window closes September 1, 2027. Anyone buying land with a plan already filed under the old code is buying a timeline that is running out. If the application isn't acted on by that date, the project falls under the new code, with new rules on what can be built and how.

Those rules are substantial. Every property in the city is now assigned to one of 14 character districts, from CD-1 for undeveloped land to CD-5 for dense, mixed-use areas downtown. Gallatin News described each district as bringing setbacks, permitted building types, landscaping, parking, signage and frontage standards into one consistent layout. NewsChannel 5's May coverage of the draft reported that the districts would also govern building heights, materials, roof types, and even the design of front porches and garage doors.

Developing Under the Rural Overlay Means Preserving Half the Land

For buyers looking at acreage on Gallatin's edges, the biggest change is the Rural Conservation Overlay District, Section 3.5.5 of the adopted Article 3. Property "may be designated within the RCOD on the Official Zoning Map." In those areas, the stated purpose is a plan that clusters development and permanently protects the rest of the land as farmland or natural open space.

The mechanics are specific. To develop under the overlay's standards instead of the parcel's existing zoning, the owner must rezone the property, and the development plan and rezoning must permanently preserve at least 50 percent of the gross site area. The ordinance divides the site this way:

Put simply, a 100-acre parcel developed under the overlay's rules would put its development on no more than half of that land. The district standards in Article 4 show what the lower-density share allows. CD-2 caps density at one unit per acre, requires lots at least 120 feet wide, and permits the House and Civic building types. Duplexes, townhouses, multifamily and mixed-use buildings are not permitted there. In CD-1, the House building type isn't permitted at all.

So a price per acre on edge land means different things depending on whether the parcel is in the overlay. Whether it is depends on the adopted zoning map dated September 1, 2026, which lists the RCOD in its legend. Look up the specific parcel on that map and confirm with the Gallatin Planning Department before relying on a rural label in a listing.

The Map Can Still Change, Parcel by Parcel

A designation on the map today isn't guaranteed to stay. The same summer that produced ZoCo also showed how a parcel's status ends up before the Council.

At the July 21 meeting, according to Gallatin News, the Council approved on first reading, by a 6–1 vote, a proposal to move 255 acres of recently annexed property near the Meta data center from rural to the General Urban Character District and add it to the Gateway Industrial Center. At the same meeting, a property owner's request to annex 29.67 acres near Old Highway 109 and State Route 109 failed 4–3, after opponents noted it was not yet clear whether the Gallatin Department of Electricity could serve the area. Both were questions about what a specific piece of land could become, and both were decided by Council vote.

Council members also said openly that the map and the city's long-range plan don't always line up. "When I look at the new zoning map and when I look at the map in Plan Gallatin (the city's official comprehensive growth policy and long-range master plan), there are plenty of areas that don't agree, one with the other," Councilman Pascal Jouvence said at the July meeting, as Gallatin News reported. He also said he liked the new open-space designations. Mayor Paige Brown raised a different concern in the same coverage: "When only national builders can meet your requirements, that's the only ones we're going to get."

The final version added one more layer. City Planner Brian Rose presented new data-center conditions at the September 1 meeting, as Gallatin News reported. Data centers are removed from the light-industrial live-work district and allowed only with conditions in the two industrial districts. They need Planning Commission approval and must sit at least 200 feet from any property boundary and 500 feet from any residence. Rose said the 500-foot figure was based on the Meta Data Center being 800 feet from a residence. Mayor Brown acknowledged that adjustments might still be needed in the future.

For a buyer, the practical takeaway is that a property's zoning is best checked as of the week of the offer, not the week the listing went up.

A Short FAQ

Does a short-term rental permit transfer to the buyer of a Gallatin home? For a rental operating before September 1, 2026, the adopted ordinance says operation as a short-term rental terminates on sale of the property. A buyer who wants to operate one would apply as a new operator under the permit, inspection, insurance and local-contact requirements in Article 9.

I'm buying land with a development plan already filed. Which code applies? The application can be reviewed under the ordinance in effect when it was submitted, but only until one year after the effective date, which lands on September 1, 2027.

How do I know whether acreage is in the Rural Conservation Overlay? Check the parcel on the adopted September 1, 2026 zoning map and confirm with the Planning Department. Developing under overlay rules requires a rezoning that permanently preserves at least half the gross site area.
