Township appeal results overview

This dataset reflects Cook County Assessor appeal results for Maine Township for tax year 2025, including property class, proposed assessed value, final assessed value, and the recorded outcome (Change vs No Change). Township-level results matter because reassessment and appeal outcomes can vary meaningfully by location and property type, which affects your next property tax bill. For ongoing township insights and deadlines, Cook County Tax Appeals regularly publishes Cook County appeal resources.

Overall appeal success rate in Maine Township

Out of 24,773 appeals analyzed, 5,575 were marked Change, meaning the assessed value was reduced. That yields an overall success rate of 22.5%.

A simple way to interpret this:

• Successful appeal = outcome shows Change (a reduction).

• Unsuccessful appeal = outcome shows No Change (or anything other than Change).

If you are deciding whether to appeal, this kind of result tracking can help you set realistic expectations and focus on evidence that typically moves the needle (market value support, income/expense for commercial, corrected property characteristics, and strong comparables).

Appeal success rate by property class

Cook County appeals are filed across different major class types (for example residential vs commercial). Here is how success rates came out in Maine Township (2025). Class codes below are grouped into major class types for clarity:

• Class 2 (Residential): 21.7% (5,090 successful out of 23,495)

• Class 5 (Commercial): 36.5% (370 successful out of 1,014)

• Class 3 (Multi-family): 55.3% (94 successful out of 170)

• Class 6 (Industrial): 42.9% (9 successful out of 21)

• Class 1 (Vacant land): 12.5% (8 successful out of 64)

Assessed value changes explained (Proposed AV vs Final AV)

Across all appeals in this Maine Township dataset:

• Average Proposed AV: $65,809

• Average Final AV: $63,930

• Average change: -$1,879 (about -2.9%)

Why this matters: assessed value is a key input into your property tax bill. When an appeal changes the assessed value, it can reduce the taxable base used in the calculation. Even if your appeal is not successful, understanding the gap between proposed and final outcomes helps you benchmark what is happening township-wide and plan for future appeal cycles.

What these results mean for property owners

If you own property in Maine Township, the data suggests:

• Reductions were not automatic. Most appeals ended in No Change, even though a meaningful minority did achieve a reduction.

• Commercial and multi-family saw higher success rates than residential in this dataset, which often reflects evidence differences (income/expense support, vacancy, rent rolls, and stronger valuation documentation).

• Timelines matter. Cook County appeal windows are short and tied to when townships open and their “last file date.” Missing the window can eliminate your chance to challenge that year’s assessment.

FAQ (common searches about Maine Township and Cook County appeals)

1) What does “Change” mean on a Cook County Assessor appeal?

“Change” indicates the Assessor’s decision resulted in a change to the assessed value (typically a reduction), which is why it is commonly treated as a successful outcome in reporting.

2) Do I appeal with the Assessor or the Cook County Board of Review?

You can appeal with the Assessor first, and if needed, you may also appeal to the Cook County Board of Review, which is a separate agency and a common next step after the Assessor’s decision.

3) What evidence usually helps a Cook County commercial property tax appeal?

Commercial and industrial appeals often rely on income/expense information, vacancy, market data, and valuation documentation, since the Assessor uses market data and modeling to estimate value.

4) Where do I find township appeal deadlines?

Cook County property tax appeal deadlines vary by township and are strictly enforced. If you miss the filing deadline, you cannot appeal that year’s assessed value. cookcountytaxappeal.com provides an updated Cook County appeal deadlines page showing township opening dates, last file dates, and active appeal periods. Property owners use this resource to track deadlines and file on time.
