What Caddo Mills is like
Caddo Mills is the small Hunt County town just past the Rockwall County line on Interstate 30, eight miles southwest of Greenville where State Highway 66 crosses FM 36. For most of its history it was a farm town of a few hundred people. The 2020 Census counted 1,495 residents; the Census Bureau's July 2025 estimate is 5,715, an increase of 284 percent in five years and the steepest growth rate of any town we cover. The city's homepage says 5,500 residents, and its economic development corporation projects more than 15,000 by 2029. Nearly all of that growth is new subdivisions north and south of the interstate.
The name comes from a mill. Caddo people camped along Caddo Creek before settlers arrived in the late 1850s, and about twenty years later I. T. Johnson and Henry King built a gristmill a mile west of the present townsite. A post office opened on June 16, 1879, and by the early 1880s the community had about 100 residents, three churches, a school and a dozen businesses. The Missouri, Kansas and Texas Railway came through in 1886 and the town grew around the depot; the Caddo Mills Banner began printing in 1897 and the State National Bank opened in 1905. The population reached about 700 around the First World War, fell to 390 by the early 1940s, when the city had incorporated, and stood at 1,338 in 2010. City Hall is at 2313 Main Street.
What is here
Caddo Mills is a town that is still building its civic life. The city owns and runs Caddo Mills Municipal Airport on FM 1565, with an airport manager and an advisory board, which makes it one of the few small towns in the area with a general aviation field. City Lake Park on County Road 2700 is getting a 20-acre improvement with a parking lot and walking trail, scheduled for completion in spring 2026. There is no big-box retail in town; Greenville is eight miles to the northeast and Rockwall's Interstate 30 corridor is west along the highway. The city council has been annexing land along FM 36, FM 1565 and the interstate to keep up with developers, and the economic development corporation says about 7,000 homes are projected by 2029.
Schools
Caddo Mills is served by its own district, Caddo Mills ISD, home of the Foxes, with its office at 100 Fox Lane. The campuses are Caddo Mills High School at 3049 South FM 36, Caddo Mills Middle School and Caddo Mills Intermediate on Gilmer Street, Frances and Jeannette Lee Elementary next to them, Kathryn Griffis Elementary on FM 1565 and the newer Kirkpatrick Elementary on Trailstone Drive. In the 2025 state accountability ratings the district earned a B with a score of 85. Griffis Elementary earned an A at 91, the high school a B at 89, the middle school and Lee Elementary a B at 84 each, and the intermediate campus a B at 80. Voters approved a $90 million bond, 1,952 to 1,766, mainly for growth, including a new high school. A district this size means one campus per grade band and no attendance-zone puzzles, which some families prefer.
Getting around
Interstate 30 runs along the south edge of town and is the route to Rockwall and Dallas. TxDOT plans to rebuild four overpasses between Greenville and the Rockwall County line, and a new FM 36 loop around the town is under way. In February 2026 TxDOT laid the final surface on FM 36 from US 380 to the city limits and added a right-turn lane at SH 66 and FM 36 at the city's request to ease the main intersection. FM 1565 and FM 1903 run north and south through the growth areas. Census data puts the mean commute for Caddo Mills workers at about 33 minutes.
Who lives here
The newcomers are young families. Census figures for 2020 to 2024 put 29 percent of residents under 18 and 12.2 percent under five, the highest share of small children of any town we cover. Households average 2.78 people. The median household income is $107,067, 71 percent of homes are owner-occupied, and the median value of an owner-occupied home is $299,700, the lowest of the nine towns. About 30 percent of adults hold a bachelor's degree. The city cites a median age of 48 and the development corporation a median age of 37, which is the difference between the old town and the new subdivisions.
For buyers, Caddo Mills is where new construction is cheapest along the I-30 corridor, with a small single-campus school district and a town whose roads, parks and retail are a step behind its rooftops. The live stats above come from our own listings here and will often be thin.
Main Street still holds City Hall and the police station, and the Katy right-of-way that made the town in 1886 runs beside it. Non-emergency police calls go through Hunt County dispatch, which tells you Caddo Mills is still a county town at heart, with the new neighborhoods arriving faster than the institutions around them.
