In 2006, Lakeside conducted a first-of-its kind study of large rental properties in the Rogers Park neighborhood. Its Community Housing Audit involved reviews of Cook County Assessor records and exterior inspections of multifamily rental properties by trained volunteers. The project produced a comprehensive picture of the neighborhood’s rental housing supply, revealing now only what was lost due to condominium conversions, but also what was at risk of being lost from additional conversions and the rehabilitation of buildings into higher-cost rentals.
