The Cook County Assessor's Office is responsible for setting fair and accurate values for 1.8 million parcels of Cook County property in a fair, ethical and transparent way.

Our public service responsibilities, however, are not limited to setting property values. In addition to working with other government agencies to stimulate economic development, job creation and the construction of affordable housing, we also seek to help county residents better understand the assessment process and take advantage of money-saving exemptions the office provides.
