Should you look at your Cook County property assessment this year?
This tool shows you how your home's assessed value compares to similar homes nearby, using the county's own public records. It presents the data. You decide what, if anything, to do with it. It does not tell you whether to appeal, and it cannot file anything for you.

Is this your township's reassessment year?
Cook County reassesses one third of its townships each year on a three-year rotation. In county data for 2023 and 2024, appeals filed in a township's reassessment year succeeded at roughly double the rate of other years.
