COOK COUNTY ASSESSOR -
RIVER FOREST TOWNSHIP TRIENNIAL REASSESSMENT
River Forest Township is now open for assessment appeals until Tuesday June 2nd.
2026 is the first year of the triennial assessment cycle. All River Forest Township properties will receive a new property assessment value. Reassessment notices were mailed on April 20th, by the Cook County Assessor's Office. Read a valuation summary and learn more about the reassessment on our website.
If records indicate the property is not assessed equitably, appealing in the first year of a triennial reassessment may give residents the best chance at lowering their assessed value.
