2015 was a quadrennial reassessment year for the 5 collar counties surrounding Cook County and 2015 assessments were adjusted to reflect 2015 market values. During the remaining years of the 2015 quadrennial (2016 to 2018), assessments will be adjusted annually by local “factors”, which adjust assessments for appreciation in real estate values since the 2015 quadrennial reassessment. The collar county assessing officials report that 2015 factors will range from 3% to 12% depending on the township, but that most are expected to be in the 6% to 7% range.
