Del Webb, a publicly traded company when Sun City Texas was originally conceived and through the first several years of homebuilding, was later sold to Pulte. Residency is restricted to persons over age 55, or in the case of couples, one of which must be 55 years of age (except in the instance of guardianship and marriage). Sun City Texas is made up predominately of single-family dwellings, but also has a small number of duplexes. For marketing purposes, near the main activity center there are a limited number of attached houses called Vacation Get-Aways (each complete with a golf cart), which are used for providing low-cost overnight accommodations for prospects to "live the life" of Sun City for a few days. Total build-out is approved by Georgetown for approximately 7,500 homes, which equals a total of approximately 14,000 residents.
