Condominium Association of Commonwealth Plaza v. The City of Chicago 

Condo association filed action for improper land usage against hospitals which were located within 250 feet of Plaintiffs' property. Plaintiffs challenged validity of zoning amendment as exceeding floor plan density limitations, building was not permitted use, and failed to require construction start time. Plaintiffs sought administrative review of resolution approving application for planned developments on hospital campus. Power to enact zoning ordinances falls within broad grant of home rule authority, and ordinance is not rendered unconstitutional because home-rule municipality violated its own self-imposed ordinances in enacting another ordinance. Plaintiffs cannot rebut presumption of validity of ordinance.
