A prominent commercial developer is eyeing a former used car lot in South Austin for a massive, mixed-use development that could include hundreds of apartments. Site plans filed with the city reveal that Rastegar Property Company is planning a the project at 5412 South Congress Avenue, the Austin Business Journal reported Monday.

The proposed development is on a 3-acre tract near the South Congress and Stassney Lane intersection and could include 260 apartments, described in the site plan application as a mid-rise residential apartment building, and a 6,000-square-foot retail space. It would replace a single-family home built in 1937 and the adjacent former used-car lot and building, built in 1952. Kimley-Horn is the project engineer.
