1909 N. Interstate 35 is a ±3.96-acre commercial land site located along the southbound IH-35 frontage road in San Marcos, Texas. The property is unimproved, generally level, and offers exceptional visibility and access along one of Central Texas’ primary transportation corridors. With approximately 145 feet of frontage on IH-35 and additional frontage along Telluride Street and Gunnison Drive, the site provides multiple access points and strong site circulation potential. The property is zoned General Commercial – Legacy District (GC), allowing for a broad range of commercial uses, including retail, restaurant, automotive, medical, hospitality, office, and service-oriented development. The location benefits from proximity to Texas State University, Downtown San Marcos, Central Texas Medical Center, the San Marcos Premium Outlets, and major regional employers, including Amazon’s nearby fulfillment center. Convenient access to IH-35, Highway 80, and Aquarena Springs Drive positions the site less than one hour from both Austin and San Antonio. The property is available for immediate development and is also being offered as a potential joint venture opportunity. Public water, sewer, and electricity are available, and the combination of zoning flexibility, frontage, traffic exposure, and surrounding growth makes this site well-suited for owner-users and developers seeking a high-profile commercial opportunity in the Hays County submarket.
