City Pads purchased the 246-unit building in July and plans to turn it into 80 to 90 larger apartments. About 20 to 30 percent of the renovated units — 16 to 27 — will be considered affordable housing and could be available to current tenants, according to City Pads. Monthly rent is expected to range from $800 to $1,300. In November, City Pads told the Tribune the building would close in late spring or early summer, with construction expected to start in the fall.
