Property in townships in the south and southwest suburban portions of Cook County and the City of Chicago may also be reassessed under certain circumstances and appeals are due within thirty days of the mailing of the reassessment.

These reassessments are particularly important because the initial townships have seen increases of 20% or more for some residential property and 200% or more for some commercial and industrial properties.
