Lake County Data Extract

The Lake County Data Extract historically provided parcel characteristics and tax information for all properties located in Lake County, Illinois. As of 2019, the township assessors in Cuba, Ela, Grant, Libertyville and Vernon Townships are no longer reporting detailed property characteristics to the county.  If detailed information is needed on these townships, a request should be made to the township assessor. The information contained in the extract is "as is", and Lake County does not in any way guarantee the correctness or accuracy of the information contained therein. A complete list of the data fields can be found here.

Files are available by Township and County-Wide as Excel spreadsheets.
