How to Search Illinois Property Records (Start Here)
Property records in Illinois are maintained at the county level. The County Assessor (Township Assessor in some counties) handles property valuations and assessment data. The County Treasurer handles tax bills and payments. These are separate offices with separate databases.
What this page covers: Illinois property assessment lookups, tax record searches, and parcel/ownership data. What it does not cover: Recorded documents like deeds and mortgages (those are on the Recorded Documents page) or property transfer history.
Where to start: For property values and tax assessments, start with the County Assessor (Township Assessor in some counties). For tax payment history and bills, go to the County Treasurer. For ownership verification, you may need both the assessment records and the recorded documents.
Common mistake: Property assessment records (values and taxes) and recorded documents (deeds and liens) are maintained by different offices in Illinois. The County Assessor (Township Assessor in some counties) handles assessments; the County Recorder handles recordings. Search both if you need the full picture.
