The Cook County Board of Review is accepting New Trier 2017 assessed property value appeals up to and including September 26, 2017

Assessed Property Value Appeals to be Filed by September 26, 2017

Homeowners in New Trier Township may now appeal their 2017 property assessment. While the appeal "window" closes on September 26, supplemental evidence can be submitted for another ten days.

Please consult the Board’s website,, for specific information. The Board strongly encourages homeowners to file appeals using its on-line program. Note: We recommend that you establish an account for filing rather than filing as a "guest." As a guest you cannot submit materials later or go back into the format later.

The New Trier Township Assessor’s office can assist you in filing appeals with the Board of Review.

  1. We can help you file an appeal based on "Lack of Uniformity." Our in-house software can collect comparable properties "comps" in a matter of seconds.
  2. We can help you formulate appeals based on recent purchase prices of either your property or of similar property or on recent appraisals of your property.
  3. We can help you appeal based on major misdescriptions of your property such as square footage.

While our office is generally open Monday through Friday from 9:00 am to 12:30 pm and then from 1:30 pm to 5:00 pm, we will be open most days from 9:00 to 5:00 and will hold additional hours as follows:

September 12 (Tuesday) from 5:00 pm to 8:00 pm.

September 16 (Saturday) from 9:00 am to 1:00 pm.

We generally do not take appointments. If you want us to gather comps for you, you can either stop at our office and fill out a short form or you can e-mail Deputy Assessor Len Shifflett ( with your request. If you want us to file the appeal for you, you can so indicate on the short form or you can authorize us to file on your behalf in an e-mail. In your e-mails, please leave a telephone number in addition to other necessary information. You can reach Len at 847-446-8200, and you can reach me at 847-446-8215 and at We anticipate a heavy volume of traffic and so may not be able to take every call as it comes in. To help us process your request, when leaving a voice message, please speak slowly and distinctly and tell us at a minimum your name, address, telephone number and the reason for your call.
