The Evans family lived in the Cabrini-Green housing project.
Although not stated on the show, the exterior shots were used. The
project is on the North side of the city, west of the posh Mag Mile
area. It is bordered by Scott Street on the north, Larrabee Street
on the east, Division Street on the south, and Larrabee Street on
the west. You can read more about it Cabrini-Green here:
