Assessor - Parcel Proximity

Cook County 10-digit parcels with attached distances to various spatial features. 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:<ul><li>Centroids are based on <a href="https://datacatalog.cookcountyil.gov/Property-Taxation/ccgisdata-Parcel-2021/77tz-riq7">Cook County parcel shapefiles</a>.</li> <li>Older properties may be missing coordinates and thus also missing attached spatial data (usually they are missing a parcel boundary in the shapefile).</li> <li>Attached spatial data does NOT all go back to 2000. It is only available for more recent years, primarily those after 2012.</li> <li>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 <a href="https://www.cookcountyassessor.com/assessment-calendar-and-deadlines">review and certification of values by the Cook County Board of Review</a>, though there are a few rare circumstances where values may change for the current or past years after that.</li> <li>Rowcount for a given year is final once the Assessor <a href="https://www.cookcountyassessor.com/assessment-calendar-and-deadlines">has certified the assessment roll</a> all townships.</li> <li>Data will be updated annually as new parcel shapefiles are made available.</li></ul>For more information on the sourcing of attached data and the preparation of this dataset, see the <a href="https://github.com/ccao-data/wiki/blob/master/SOPs/Open-Data.md">Assessor's Standard Operating Procedures for Open Data</a> on GitHub. <a href="https://datacatalog.cookcountyil.gov/stories/s/gzdr-q7c4">Read about the Assessor's 2025 Open Data Refresh.</a>
