One city in two counties, and a town just north of it
For a buyer, the practical consequence is that Spring Hill is not one set of rules. A home on the Williamson side carries Williamson County property tax and is served by Williamson County Schools. A home on the Maury side carries Maury County property tax and is served by Maury County Public Schools. The city layer is the same on both sides. Thompson's Station has its own, much smaller town rate on top of the Williamson County rate.
Distances below are measured in a straight line from the town center, so road distance runs longer and drive times vary widely by hour. From Thompson's Station, Cool Springs in Franklin is about 12 miles, and downtown Nashville and Nashville International Airport are each about 26 miles. From central Spring Hill the same three points are about 16, 30 and 29 miles. The Maury County Industrial Development Association's 2026 profile of Spring Hill describes the city as 30 miles from Nashville.
Two roads shape how the area connects. Saturn Parkway (State Route 396) is a 4.47-mile road entirely within Spring Hill that runs from US-31 east to I-65 at Exit 53, and it opened in 1989 to connect the General Motors Spring Hill Manufacturing plant with the interstate. The newer I-65 interchange at Buckner Road and June Lake Boulevard, a diverging diamond design in Spring Hill, opened May 31, 2024. It is listed as Exit 55 in the Interstate 65 exit list; the city and TDOT project pages do not state the number, so confirm it with a current map before giving directions.
Village retail, battlefield history, and a corridor built around one plant
Thompson's Station is organized around its rail-era town center and the master-planned villages that have grown up around it. Preservation Park carries trail markers for the 1863 Battle of Thompson's Station, and Tollgate Village holds a cluster of restaurants and shops on Tollgate Boulevard. The town is served by Williamson County Schools, and its town hall is at 1110 Fountain View Boulevard.
Spring Hill's retail runs along Port Royal Road and Main Street, with The Crossings of Spring Hill as the largest center. Rippavilla, on Main Street, has been owned by the City of Spring Hill since 2017, and the Spring Hill Battlefield is part of the same Civil War story as Thompson's Station. The city's parks include Harvey Park, Fischer Park and Evans Park.
On the employment side, GM Spring Hill Manufacturing is the largest employer listed in the Maury County Industrial Development Association's 2026 profile, at 3,252 employees. Ultium Cells, a battery cell plant, operates in Spring Hill as well, and its production schedule has changed more than once since late 2025, so anyone whose work is tied to either plant should check current status directly.
A mailing address does not settle the jurisdiction
A Thompson's Station or Spring Hill mailing address does not by itself establish that a parcel is inside the town or city limits, or which county it is in. ZIP 37179 and ZIP 37174 are postal areas, not tax or school boundaries. Confirm limits, county and utility service for the specific parcel before assuming a rate or a provider.
Master-planned villages, sorted by town and county
Much of the stock in both places is recent. The median year built across closed single-family sales over the past twelve months is about 2017 in ZIP 37179 and about 2014 in ZIP 37174. The cards below group communities by town and county, since that is what determines the tax and school layers. Figures come from individual listings and community pages, so each is an example of a band and not a quote for a section or a lot.
Tollgate Village, Bridgemore Village, Whistle Stop Farms
Master-planned villages on lots that run from about 0.15 acre in a 2015-built Tollgate home to 0.37 acre in a 2020-built Bridgemore home. Tollgate Village lists a pool, fitness center, clubhouse, tennis and sports courts, lake and greenway trails. Association dues on sampled listings ran from $100 a month in Bridgemore to $132 in Tollgate and $290 in Whistle Stop Farms, which lists a clubhouse, pool and pickleball court.
Canterbury and Fields of Canterbury
Built 2008 to 2025, with single-family lots of about a fifth of an acre and townhomes on about 0.07 acre. Amenities listed include two pools, two playgrounds, a park with a fire pit, walking trails and a community center. Dues were $115 a month for single-family homes and $285 to $295 for townhomes.
Saddle Springs
An equestrian enclave on Saddle Springs Drive, Bridle Path Court and Buckskin Court, built around the privately owned Jaeckle Center riding facility. Homes built 2009 to 2019 sit on three to seven acres, against a quarter-acre median lot across ZIP 37179. Horses are permitted on the lots, fenced pasture and barns are common, and there is no community pool. Association dues run about $720 to $750 a year. Access to the Jaeckle Center is a separate arrangement with the Center, so confirm boarding and riding terms with the Center and the association in writing before an offer.
Wade's Grove, Benevento East, Cherry Grove
Detached homes, built from 2012 onward in the sampled listings, on roughly 0.18 to 0.30 acre lots. Wade's Grove lists a pool, pavilion, playground and basketball court, with dues of $40 a month on a sampled listing. Benevento East showed $40 a month and a 0.26-acre lot, and Cherry Grove showed $54 a month with a clubhouse and pool on a 0.30-acre lot.
Harvest Point and Southern Springs
Harvest Point is a D.R. Horton new-construction community with one- and two-story plans of 1,672 to 3,971 square feet, served by Maury County Schools. Southern Springs is an age-restricted community of 55 and older with a clubhouse, fitness center, indoor and outdoor pools, and tennis and pickleball courts; one sampled listing carried $325 a month in dues. Read the age-restriction covenant closely if the household includes anyone under fifty-five.
Two districts in one city, and how to check a parcel
Confirm county first, then zoning, by address
Thompson's Station and the Williamson County side of Spring Hill are served by Williamson County Schools. The Maury County side of Spring Hill is served by Maury County Public Schools. Which district applies depends on the county the parcel sits in, not on the Spring Hill name in the address, and not on the subdivision name.
Step one is the county. Search the address in the Tennessee Comptroller's property assessment lookup at assessment.cot.tn.gov/TPAD, which covers both Williamson and Maury counties, or search the parcel on the county assessor's site. The county assessor record, and the tax bill from the Williamson County Trustee or the Maury County Trustee, show the county of record. Ask the title company to confirm the county on the survey and legal description as well.
Step two is the zoned school. For Williamson County Schools, use the InfoFinder tool at wcs.edu, under Bus Routes and School Zones. Enter the street address with the street type abbreviated, such as Rd. or St., and leave the ZIP code blank. For Maury County Public Schools, use the Find my zoned school tool at mauryk12.org, or contact the district office at 931-388-8403. Each district sets zone lines itself and can change them when buildings reach capacity or new schools open, so a builder's stated assignment is worth reconfirming before closing.
Williamson County Schools requires residency in the county for enrollment and runs a separate out-of-zone application window each spring. Maury County Public Schools posts its own out-of-zone enrollment process. The authoritative answer for a specific address comes from the district.

The tax layers, worked on a $900,000 appraised home
Tennessee assesses residential property at 25 percent of appraised value, so a $900,000 home carries a $225,000 assessment. The rate is quoted per $100 of assessed value. The three scenarios below differ only by town or city and county.
| Thompson's Station | Spring Hill, Williamson side | Spring Hill, Maury side | |
|---|---|---|---|
| County rate per $100 | $1.30 | $1.27 | $1.91 |
| Town or city rate per $100 | $0.103 | $0.739 | $0.739 |
| Combined rate per $100 | $1.403 | $2.009 | $2.649 |
| Assessment ratio | 25% of appraised value | 25% of appraised value | 25% of appraised value |
| Illustrative annual bill on $900,000 appraised | About $3,157 | About $4,520 | About $5,960 |
On the figures above
Price, days-on-market, price-per-square-foot, closed-sales and listing figures come from RealTracs data through Rechat market statistics for ZIP codes 37179 and 37174, October 2025 through September 2026. The source reports monthly values, so each twelve-month figure here is the median of the twelve monthly medians, which approximates a single twelve-month median and is not identical to it. ZIP codes are postal areas and do not match town or city limits exactly.
The Williamson County rate schedule lists $1.30 per $100 for Thompson's Station and $1.27 for Franklin and Spring Hill city limits, and a Thompson's Station town rate of $0.103, set for fiscal year 2025 to 2026. The Spring Hill rate of $0.739 applies to both counties for fiscal year 2026 to 2027 under the city's Ordinance 26-09. The Maury County rate of $1.91 is the most recent rate published by the county, from June 2025. Maury County is in a 2026 reappraisal year and its certified rate may be reset, so the Maury column should be rechecked with the Maury County Trustee or Assessor before it is relied on. The bills are arithmetic on those published rates and are not quotes. They exclude exemptions, fees and any special assessments.
Five things worth knowing before you tour
Look up the parcel in the state assessment lookup or on the county assessor's site, and ask the title company to confirm county and jurisdiction from the survey. This determines the tax rate, the school district and the city services that apply.
Use InfoFinder at wcs.edu for Williamson County parcels and the zoned-school tool at mauryk12.org for Maury County parcels. Section Four walks through the steps.
On a $900,000 appraised home the published rates produce roughly $3,157, $4,520 or $5,960 a year, depending on the town or city and county. Ask the listing agent for the current bill and compare it with the combined rate for that parcel.
Dues in the sampled listings ranged from $40 to $325 a month, and amenities, architectural rules and any age restriction vary by community and by section. Read the current documents and the most recent budget before writing an offer.
Water, sewer and trash providers can differ between the town, the city and unincorporated parcels, and between the two counties. Ask for the provider names and the most recent bills before an offer.
