Most commercial and Industrial information is not located on our website. If you need square
footage or other information, please feel free to call our office. Anyone of our staff can answer
basic information such as square footage or sale information. If you need more detailed
information or talk about the assessments you may ask to speak to the Commercial & Industrial
staff person or the Assessor.   If the property record card you seek, you can call our office for
the request. If you are requesting more than two property cards, please call for an email address
 for the staff member who can handle the request for you.  We will email or fax the property
cards, or you may come into the office to pick up a hard copy.  

Many time problems can be cleared up at our local level without a formal appeal to the Board
of Review, so it is in your best interest to contact us first before filing. The deadline for this year is July 7th, 2025 for this process.

If you have a vacancy issue, and it is during our reassessment time period, you may file a
Vacancy Affidavit with our office. The form must be notarized and can be sent by mail or e-mail
 to the Commercial & Industrial staff person or the Assessor. The deadline for this process is July 7th 2025

If you have an appraisal you would like our office to review. Please contact the office
(630) 759-1315 or email commercialdeputy@dupagetownshipassessor.com
