Startzville is on Farm Road 2673 thirteen miles northwest of New Braunfels in central Comal County. It was established in 1935 by members of the Startz family, who built a small store. With the completion of nearby Canyon Dam in 1964, the community began to grow. Although the population of Startzville proper was estimated at only thirty in 1966, much of the land near the lake was developed as residential subdivisions. Several businesses were established at Startzville to serve the general population of the Canyon Lake region. The community had a population of thirty in 1990. In 2000 the population remained the same. In subsequent years the community experienced rapid growth thanks to the construction of new subdivisions in the area around Canyon Lake. By 2009 the population was estimated at 5,000 and in 2016 it was estimated at 7,000. The Startzville Elementary School, constructed in 2008, is served by the Comal Independent School District. As of 2018 the unincorporated community of Startzville was included in the Canyon Lake CDP (census-designated place), along with the communities of Canyon City, Crane's Mill, Hancock, Fischer, and Sattler.
