“Mayor Lightfoot is committed to working with the City Council to expand affordable housing in a way that considers the unique needs of every community,” mayoral spokeswoman Eugenia Orr said in an emailed statement. “After review of the proposed ordinance, there were questions and concerns about the alderman’s proposal, as it would unilaterally ban zoning changes in areas near the 606, as well as halt any building permits in the area. We remain engaged in conversations with Alderman Maldonado and other aldermen in the area regarding potential changes to the draft ordinance.”
