Neighborhoods play an important role in residential property assessment. Single-family and residential multi-family property assessments are sensitive to neighborhood boundaries. Neighborhoods are nearly always used in statistical regression models to produce initial assessed values, and comparable properties are nearly always selected from within neighborhoods for the purposes of appeal. See data notes for additional information.

A Note from the State's Attorney's Office as of 12/30/2024:

The Cook County State's Attorney's Office believes data transparency is an important accountability and public safety tool and is committed to providing Cook County residents with this critical information. Currently, we are working to make sure that the data we share is valid, accurate, and presented in a format that is useful to the public. Our goal is to have resumed updating the Cook County open data site within the first 100 days of the new administration.
