Glenn Heights is a city divided between Dallas and Ellis counties, situated about 15 miles south of downtown Dallas along the Interstate 35E corridor. The city incorporated in 1969 and has grown steadily in the decades since, evolving from a small, semi-rural community into a residential suburb that forms part of the southern edge of the Dallas-Fort Worth metroplex. The city's defining feature is its location. I-35E runs along its western edge, giving residents a direct route north into Dallas and south toward Waxahachie and the rest of Ellis County. This corridor position has driven residential growth, adding newer subdivisions alongside the city's older, more established areas. Glenn Heights covers about 7.2 square miles, and much of its character reflects that mix of eras — a community still suburbanizing around a core of earlier development. Education is split along county lines, a common feature of cities that straddle two counties. The Dallas County portion of Glenn Heights is served by the DeSoto Independent School District, while the Ellis County portion falls within the Red Oak Independent School District. This dual-district arrangement gives families different school pathways depending on where in the city they live. Glenn Heights tends to appeal to homebuyers seeking newer construction and a suburban setting with a straightforward commute into Dallas, while the Ellis County side offers a slightly more spread-out, emerging suburban feel. Everyday shopping and services are available within the city and in nearby DeSoto, Red Oak, and Cedar Hill, and its position midway between Dallas and the growing communities of northern Ellis County keeps it well connected to the region's economy.
