Cook County Class 9 Property Tax Workshop – Aug. 15th!

Owners of Class 9 properties:

It has come to our attention that some Class 9 properties have been changed to Class 3 status, which has SIGNIFICANTLY increased their assessed values – some values have doubled or tripled. According to the Assessor’s Office, this change occurred because owners did not submit appropriate annual affidavits in 2015 and/or 2016.

Even if you think you submitted these documents, please click here for a detailed list of steps you should take to insure that you retain your Class 9 status.

If you need more information, email the Assessor’s Office at Please include your PIN and Control Numbers in your email correspondence.

The Preservation Compact is holding a Class 9 Workshop to address questions regarding this process. Please click here to RSVP.

(If you do NOT have Class 9, this workshop is NOT about applying for Class 9. Click here for more information about applying.)
