About Southwest Hills
Southwest Hills is a residential neighborhood in western San Marcos, Texas (Hays County), situated in the wooded hills northwest of Wonder World Drive and southwest of Post Road. The neighborhood has approximately 826 residents and developed organically over several decades rather than as a single master-planned community. Most homes were built between 1970 and 1999, with additional construction from the 2000s to the present. The area is not a gated community and is not governed by a single master-plan HOA.
Housing in Southwest Hills consists primarily of single-family homes in traditional and ranch styles, often featuring limestone or brick exteriors with attached garages or carports. The neighborhood includes a mix of smaller two-bedroom residences and larger four-bedroom properties. The area sits in the rolling terrain of the Texas Hill Country, with mature tree cover and wooded lots throughout. Craftsman bungalows, Cape Cod designs, and custom homes are also present in the housing stock.
