Chicago property records: what’s public for any address
Type a Chicago address to resolve it to its Cook County parcel — its 14-digit PIN, assessed value, and appeal history. Below: what’s in the public record and how to read it.
What’s in a Chicago property record
Every parcel in Chicago is public record through Cook County. Enter an address and Civic Worth resolves it to its 14-digit PIN, then joins the county and city sources that describe it: assessed and equalized value, classification, and where the parcel sits in the assessment-appeal pipeline.
The 2027 reassessment makes this timely — the parcel page shows comparable values at each appeal stage (mailed, certified, Board of Review), so the record reads as a pipeline, not a single guess. Every figure carries its source and “as of” date.
Source: Cook County Assessor and City of Chicago public records, joined and timestamped by Civic Worth. Confirm any figure against the county before relying on it.
Frequently asked
- What property records are public in Chicago?
- For any Chicago address, the parcel’s 14-digit Cook County PIN, its assessed and equalized values, its classification, and its assessment-appeal history are public records. Civic Worth resolves an address to its parcel and shows these on the parcel page with an “as of” date.
- What is a Cook County PIN?
- A Property Index Number is the 14-digit identifier Cook County assigns to every parcel of land. It is the key that ties an address to its assessment, tax, and ownership records. Entering an address resolves it to its PIN.
- How does the 2027 reassessment affect my property record?
- The City of Chicago triad is reassessed in 2027. Civic Worth shows comparable parcels’ values at each appeal stage — mailed, certified, and Board of Review — so you can read the reassessment as data rather than a single number.
