Our History


Sub 4 Development Company was started in 2015 as the real estate development branch of Green Street Realty.  The goal was to build high quality student housing, multi-family housing and retail projects in house and not rely on an outside contractor to build our developments. Since its inception, we have been one of the most active builders in the Champaign-Urbana. Illinois market, building  numerous new construction projects. As we continue to grow, so does our footprint, with plans on starting development projects in areas such as  Colorado Springs, CO, Phoenix, AZ, Ann Arbor, MI and Lafayette, IN. As of the summer of 2020, we have a second office in Scottsdale, Arizona. 


Our Developments:

  • Apartment complexes
  • Large Scale Remodels
  • Retail spaces
  • Restaurants
  • Commercial real estate
  • & more!


Once our projects our complete we turn it over to our management company, Green Street Realty.  Green Street Realty specializes in property management and manages all Sub 4 Developments after completion.
