There are 38 townships in Cook County and they are divided into three districts for the purposes of reassessment within a triennial cycle. Oak Park Township is part of the South Suburban triennial group which is being reassessed in 2023.
We recommend homeowners review their assessment annually, particularly in a triennial reassessment year, to ensure they do not pay more than their fair share in property taxes. Successfully appealing in a reassessment year may provide 3 years of savings on future property tax bills. If you would like a free analysis of your Oak Park Township home in comparison to similar properties, we would be happy to conduct a “no obligation” analysis and provide you with a free estimate of how much we believe we could help you save with an appeal.
