At the end of July 2021, a bill was introduced in the House and Senate, which, if enacted, would create a federal tax credit to fund the conversion of unused office buildings into residential, commercial, or mixed-use properties. The Revitalizing Downtowns Act (S. 2511), which is modeled after the federal historic rehabilitation tax credit, would provide a federal tax credit equal to 20 percent of “qualified conversion expenditures” with respect to a “qualified converted building.”
