Occupancy Affidavit Online


The Occupancy Affidavit is one type of document that can be used to show that a home was (or is) the primary place of residence for a specified time period. It is a document that is attached to an application, such as a Senior Exemption.

The Cook County Assessor's Office has recently made this affidavit and exemption applications available online. In our continued efforts to improve our services, the Office has temporarily waived the notarization requirement typically required for this affidavit.
