In September 2026, developers completed the transformation of Chicago's 121-year-old Bellwether building, turning 11 floors of office space into 117 residential units. This project represents the first finished office-to-housing conversion in the Chicago Loop.
Why it matters
The initiative addresses downtown housing shortages and record-high office vacancy rates by repurposing underutilized commercial buildings. It serves as a testing ground for wider efforts to integrate residential life into the historic business district.
The Bellwether project utilized $28 million in city tax increment financing alongside $7.8 million in federal historic tax credits. Of the 117 units, 41 are reserved for households earning 60% of the area median income.
