The Riverside Township Assessor’s Office acts as a taxpayer advocate for local residents in the Cook County property tax system. With almost 1.8 million parcels in Cook County, assessments are determined triennially through a mass appraisal system by the Cook County Assessor. Riverside Township contains about 6,457 of those parcels. Our goal is to ensure taxpayers that their property is fairly and accurately assessed. Our job is to provide assistance and educate our taxpayers as they navigate the property tax system.

The Township Assessor’s Office, operating independently of the Township Office, is located on the 3rd floor of the Town Hall building. Our Township Assessor, Frances (Fran) Sitkiewicz, can be reached Monday through Friday, from 9am until 2pm, at (708) 447-7700 or by email at [email protected]riversidetownship.org.
