Uptown buildings are not in Cook County’s 2026 reassessment, and that is easy to miss if you only see the notices going out in the south and west suburbs.
The Cook County assessor’s assessment calendar, last updated Nov. 6, says the county reassesses on a three-year cycle. In 2026, the south and west suburbs are the ones being reassessed, and those owners are getting new estimated fair-market values in the mail. “Properties in the north suburbs, and City of Chicago only undergo reassessment if there is a change due to division work, permit applications, or other special circumstances,” the calendar says. If that happens, the owner gets a notice with a new value and an appeal deadline.
The city’s next regular turn in that cycle is 2027, a point also made in coverage of this year’s tax bills, including the Sun-Times’ report on Treasurer Maria Pappas’s analysis. This year’s Chicago bills still went up — the treasurer’s office put the median city homeowner increase at 3.2% — but they were built on the existing assessment roll, not a fresh citywide revaluation.
That does not mean an Uptown owner has nothing to watch. A permit, a division of a lot or other special work can still trigger a new value this year. And 2027 is the year when the city as a whole is due to be reassessed again. The assessor’s calendar is the place to confirm dates as that cycle opens. For now, the official word is that Chicago is not in the 2026 mass mailing.
