Hanover Township 2026 appeal status

What homeowners should check before filing
- Verify the property record. Building size, class, age, and other characteristics affect whether another property is a defensible comparison.
- Compare assessments, not just sale prices. A uniformity appeal asks whether similar homes are assessed consistently.
- Favor physically similar evidence. Nearby properties matter, but similarity in class, size, age, construction, and condition matters too.
- Preserve the filing deadline. Official Cook County dates control, even if you are still improving the supporting evidence.
How comparable properties support a Hanover appeal
Cook County's current rules emphasize comparable properties that are similar in characteristics and location. Simple Tax Appeal screens Cook County parcel and assessment data to help identify defensible lower-assessed matches instead of treating every nearby property as a useful comp.
