Apartment building owners will face a wave of new cooling requirements under an ordinance advanced on Tuesday with the goal of preventing the kinds of excessive indoor heat that saw three elderly Rogers Park women die in their apartments last month. While the proposal faced headwinds in committee, it passed with unanimous support after its sponsor agreed to keep negotiating on its most controversial provision.

The ordinance (O2022-1753), a collaboration between Ald. Maria Hadden (49) and the Chicago Department of Buildings, was the only citywide measure among dozens of other zoning proposals that earned the unanimous endorsement of the City Council Committee on Zoning, Landmarks and Building Standards on Tuesday. They included a major adaptive reuse project in Austin and the latest proposed addition to Fulton Market’s growing skyline.
