Cook County property data for 2006-2016

Map of two properties in Cook County and the attributes of one are shown (taken from the sample file)

This dataset has details for 1,879,504 parcels, properties, and condos in Cook County, including property tax bill values between 2009 and 2016, assessment values, appeals status, exemptions, building size*, building age*, and lot size*. It also has geography for every property, ready for analysis in a GIS format. This is the same information that our Cityscape Pro members have access to in a filtered form, and this is the only way to get the entire dataset.

This dataset is also available with 86,136 vacant parcels only, for $199.00.

The dataset includes

  • appeals and exemptions information for 2012-2016
  • property class and descriptions for 2014-2016
  • taxpayer mailing address for 2015, 2016
  • condo unit number in the address_assessor field
  • building age as a function of property_tax_year minus the building_age field

*These fields are "where available" as the detail doesn't exist for all properties.

It comes as a GeoPackage file for GIS, and as a CSV file for spreadsheet software. Because the file is 1.3 GB compressed in a ZIP file, we will share with you a personal link from which to download it.

GeoPackage GIS file (opens in QGIS and ArcGIS), CSV (opens in many programs) - the CSV file contains only the latitude and longitude of the centroid of the parcel, while the GeoPackage contains the actual parcel shape as a polygon (a minority of parcels have only a point shape)
