Thanks to a new dataset provided by the Cook County Assessor's Office, Chicago Cityscape now shows the owner names of tax-exempt properties. This includes properties owned by non-profit organizations, places of worship, and municipal and other government agencies. The dataset is integrated with Property Finder (part of the "Tax exempt status" filter) and each Property Report's Property & Ownership info section. 

The dataset, at the time of publication, includes information about 92,302 properties owned by 5,725 unique owners. The City of Chicago is attached to 19.2 percent of the properties; the Cook County Forest Preserve District is attached to 3.9 percent of the properties. Other top owners include Cook County, the Chicago Housing Authority (CHA), the Catholic Bishop of Chicago, the Chicago Board of Education, the Illinois Department of Transportation (IDOT), and the Chicago Transit Authority (CTA).

The tax-exempt property owner name will appear in a new column in any data export from Property Finder.

Additionally, it's possible to filter for properties owned by a specific tax-exempt owner. In Property Finder, look for the "Tax exempt status & owner" filters and enter a one-word name in the search field and select from the results. Then select the "Apply filters" button.

Many of the owner names are misspelled or abbreviated in unexpected ways, an issue in the source dataset. We have implemented a solution that repairs and improves the names of the most prolific owners making it possible to, for example, search for "CHA" to find the Chicago Housing Authority.
