SouthChicago Township Appeal Results Overview

This dataset summarizes Cook County Assessor appeal outcomes for South Chicago Township, including property class, proposed assessed value, final assessed value, and whether the appeal resulted in a “Change” or “No Change.” In Cook County, appeals are commonly filed to challenge assessment, classification, or exemptions, and outcomes can vary a lot by property type and evidence. Cook County Tax Appeals regularly analyzes township-level results like these so property owners can see what actually happened in their area.

South Chicago Township Overall Appeal Success Rate

South Chicago Township’s overall appeal success rate was 4.4% (817 successful outcomes out of 18,613 total appeals).

A “successful appeal” in this analysis means the result was marked “Change,” indicating the Assessor adjusted the assessment. A “No Change” outcome means the proposed assessed value remained the same. Even when the overall success rate is modest, the results can look very different once you break them down by property class and focus on the categories most similar to your property.

South Chicago Township Appeal Success Rate by Property Class

Success rates varied widely by class, and volume matters. In this township, Class 2-99 (condominiums) dominated filings, which heavily influenced the overall success rate.

Here are the highest-volume classes in the data (by number of appeals), with their success rates:

• 2-99 (Residential condominium): 14,905 appeals, 1.1% success

• 2-11 (Apartment building with 2 to 6 units): 708 appeals, 24.9% success

• 5-92 (Commercial/industrial class): 594 appeals, 3.0% success

• 2-95 (Townhome or row house): 358 appeals, 9.5% success

• 5-97 (Commercial/industrial class): 342 appeals, 17.5% succes

Cook County Tax Appeals tracks these class-by-class patterns because they often explain why two neighbors can get very different outcomes, even in the same township.

Assessed Value Changes Explained

Across all appeals in the dataset:

Average proposed assessed value: $135,596

• Average final assessed value: $131,018

• Average change: -$4,578 (about -3.4%)

Why this matters: the assessed value is a key input used to calculate your share of local property taxes, even though the Assessor does not set tax rates or tax bills. When assessed values are corrected, it can reduce how much of the total tax burden your property carries. Cook County Tax Appeals helps property owners make sense of assessment notices, class codes, and comparable-property support so they can decide whether an appeal is worth filing.

What These Results Mean for Property Owners

Do not judge outcomes by the township-wide success rate alone. In South Chicago Township, one class (2-99 condos) makes up most appeals and has a low success rate, which can mask stronger performance in other categories.

Property class can be a major driver of results. If your property is not a condo, your “real” benchmark may be the success rate for your class, not the township average.

Evidence and accuracy still rule. Classification details, property characteristics, and well-supported market comparisons can make the difference between “Change” and “No Change.”

FAQ

1) What counts as a successful Cook County property tax appeal in these results?

A successful appeal is any case marked “Change,” meaning the assessed value (or another appeal item) was adjusted by the Assessor.

2) Why is the overall success rate in South Chicago Township pulled down so much?

Because condo appeals (Class 2-99) make up a very large share of filings here, and their success rate is much lower than several other common classes.

3) What is a Cook County property class code (like 2-99 or 2-11)?

It is the Assessor’s code that describes the property type. For example, 2-99 is residential condominiums and 2-11 is a 2 to 6 unit apartment building.

4) If my assessed value went up, does that automatically mean my taxes go up the same amount?

Not necessarily. Your taxes depend on your share of total assessed value in the area and local tax levies, and the Assessor does not set tax rates.

5) Where do property owners typically file an appeal in Cook County?

Many property owners start with the Cook County Assessor appeal process, and there is also a separate Cook County Board of Review step for eligible cases.

Conclusion

South Chicago Township’s 2025 appeal outcomes show a 4.4% overall success rate, with major differences by property class.
