Cook County Assessor's Office

Cook County Assessor's Office Through fairness, ethics and transparency, the Assessor's Office is responsible for setting values for 1.8 million parcels of Cook County property.

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.
