Cook County properties are reassessed on a triennial schedule. Every three years, the new valuations – along with appeals, exemptions, local tax levies, and assessments of nearby properties – determine the amount of future property tax bills.

For the purposes of reassessment scheduling, the thirty townships within Cook County are divided into three groups:

  • North/northwest suburbs
  • South/southwest suburbs
  • City of Chicago

Impact on Community Associations

Condominium, homeowner (HOA), and townhome community association assessment appeals require careful analysis and preparation. Here’s a short explanation video:

The property tax appeal should be filed as a group on behalf of all units to streamline the process. This will benefit all unit owners and ensure uniformity of taxation within the association.

There are several agencies in the appeal process. Each one comes with its own caveats and pitfalls. Accordingly, associations should seek out skilled legal counsel to steer them through the appeal.
