Assessor - Parcel Proximity
Listed in Open Data Portal for Cook County Government
Cook County 10-digit parcels with attached distances to various spatial features.
Description
When working with 10-digit Parcel Index Numbers (PINs) make sure to zero-pad them to 10 digits. Some datasets may lose leading zeros for PINs when downloaded. 10-digit PINs do not identify individual condominium units.
Additional notes: Centroids are based on Cook County parcel shapefiles . Older properties may be missing coordinates and thus also missing attached spatial data (usually they are missing a parcel boundary in the shapefile). Attached spatial data does NOT all go back to 2000.

It is only available for more recent years, primarily those after 2012. This dataset contains data for the current tax year, which may not yet be complete or final. Assessed values for any given year are subject to change until review and certification of values by the Cook County Board of Review , though there are a few rare circumstances where values may change for the current or past years after that.
Rowcount for a given year is final once the Assessor has certified the assessment roll all townships. Data will be updated annually as new parcel shapefiles are made available. For more information on the sourcing of attached data and the preparation of this dataset, see the Assessor's Standard Operating Procedures for Open Data on GitHub.
