Calumet Township 2025 Assessment Notices Mailed
2025 property assessment notices were mailed by the Cook County Assessor’s office on July 30th, 2025, to Calumet Township property owners. The following cities, towns, and villages are in Calumet Township: Blue Island (east half), Calumet Park, and Riverdale. The window to appeal your 2025 assessed value is now open until the deadline of September 11th, 2025.
We suggest property owners review their assessments annually and appeal whenever there is a strong evidence based argument that your home may not be assessed fairly. Calumet Township’s next triennial reassessment is scheduled for 2026. However, if you feel that your assessment is not fair there is no need to wait to appeal, property owners have the right to appeal every year at the Assessor’s office and at the Board of Review. If you’d like a professional opinion on your home’s assessed value as it compares to similar properties in your neighborhood contact us for a free, no obligation, review and analysis of your home.
