Information on Appeals

The 2026 Dorr Township assessments will be published Wednesday, July 22, 2026 in the Woodstock Independent. The 2026 assessment notices will be online to view at McHenry County Notice of Assessments on July 22, 2026. The deadline to appeal the 2026 assessments for Dorr Township will be Friday, August 21, 2026.

How to File:

1. All assessment appeals are filed online through the County. The link below will have the appropriate complaint forms, instructions and guidelines to help you with filing your complaint. You can file your appeal here.
2. There are two types of appeal choices-Residential or Commercial/Industrial. With each appeal you will be required to provide documentation.
3. When completing your appeal form, you have the option for the Board of Review to make their decision based on the evidence provided (no oral hearing necessary). At these hearings, neither Township Assessor nor property owner is present. If the option is selected to have a scheduled, in-person hearing, you must be prepared to present your evidence. The option for this type of hearing may be appropriate if you believe you have unusual circumstances that can best be stated personally. The location, date and time of these hearings is determined by the Board of Review.
4. All completed appeal forms must be filed online on or before the deadline date. You may wish to make a copy for yourself.
5. If you do not have access to the internet please call the Dorr Township office for other arrangements.

Comparable sales should be chosen as close to January 1, 2026 as possible.
Please see the Filing a Complaint document for additional information.

Sales List:

To better serve our township residents, we are providing a Sales List of sold properties in Dorr Township from January 1, 2025 – July 1, 2026. This list must be used in conjunction with the Property Search feature on our website to help fill out the comparable grid on your appeal form. Please note that some of the homes with low sale prices may not have been an arm length sale.

How to use the Sales List:

1. Use the appropriate  Sales List to help find your comparable sales. Find three to four comparable sales that are similar to your property. For example, if you have a one-story, single family residence, try to find similar one-story homes of comparable age, square footage, condition, and neighborhood. The comparables do not have to be an exact match to your property; adjustments are made for differences.
2. After choosing your comparable sales, go to our  Property Search and enter the Parcel Number or Property Address for each sale you chose. Click on the property link to display the property record. Fill out the comparable grid on your appeal form with the information on the property record.
3. Our office will provide small photos of your property when we submit our information to the Board of Review. So, unless you wish to provide larger photos, your own photos are not a necessity. The exception is if you are filing an appeal based on the condition of your property. In this case, interior and/or exterior photos with a date stamp are helpful to determine the amount of depreciation.

Please note there may be additional sales that you are aware of, that are not on the sales list.
These sales may have been recorded outside the timeframe of January 1, 2025 – July 1, 2026. These sales should still be able to be found under our website Property Search.
