This review looks at how property tax appeals turned out across Hyde Park Township in 2025, spanning residential, multifamily, vacant land, commercial, industrial, and incentive property classes. In Cook County, different property classes follow different assessment rules and appeal patterns — which is exactly why township results vary so much by property type.
Data Overview
| Homeowner appeals (each appeal counted once) | 2,289 |
| Successful appeals (marked "Change") | 385 |
| Homeowner success rate | 16.8% |
| Average cut, winning homeowner appeals | ~12.5% |

Overall Success Rate
A successful appeal here means the outcome was marked "Change." By that rule, and counting each appeal once (a condo building's units, decided together, are one appeal), 385 of 2,289 homeowner appeals succeeded — a 16.8% success rate; across all property types, 588 of 2,971 (19.8%). Most appeals did not produce a change, but a meaningful share did, and even a single successful appeal can lower assessed value enough to affect future tax bills. That's why it pays to review your assessment carefully before deciding whether to file.
Success Rate by Property Class
Cook County's major property classes break down roughly as: Class 1 vacant land, Class 2 residential, Class 3 larger apartment/multifamily, and Class 5 commercial and industrial. The clearest pattern in Hyde Park: commercial classes substantially outperformed residential ones.
| Class | What it represents | Appeals | Success |
|---|---|---|---|
| 2-99 | Residential condominium | 118* | 22.0% |
| 2-11 | Apartment building, 2–6 units | 904 | 16.4% |
| 2-03 | One-story residence (1,000–1,800 sq ft) | 358 | 13.7% |
| 3-15 | Multifamily apartments | 274 | 19.3% |
| 2-06 | Larger older residential homes | 188 | 18.1% |
| 5-17 | One-story commercial buildings | 108 | 58.3% |
| 2-10 | Row house or townhome | 156 | 18.6% |
| 1-00 | Vacant land | 80 | 11.2% |
| 5-90 | Commercial minor improvement | 39 | 46.2% |
| 2-95 | Individual townhomes | 85 | 16.5% |
The standouts are commercial: Class 5-17 (one-story commercial) won 58.3% of the time and Class 5-90 (commercial minor improvements) 46.2% — well above the residential classes that made up most of the volume. *Condo appeals (2-99) won 22.0%, above the 16.8% homeowner rate; a condo appeal often covers a whole building, so 118 appeals covered 1,365 units.
What Happened to Assessed Values
Across the dataset, assessed values moved meaningfully on the appeals that succeeded:
| Average cut, winning homeowner appeals | ~12.5% |
| Typical (median) cut, winning homeowner appeals | $3,414 |
| Average cut in dollars, winning homeowner appeals | $10,045 |
| Homeowner appeals with no change | ~83% |
| Total reduction, winning appeals of every property type | ~$24.9 million |
Because property taxes are tied to assessed value, these reductions flow directly into lower tax liability. Not every appeal succeeds — but the ones that do can mean real savings, and they compound year over year until the next reassessment.
What This Means for Property Owners
Three takeaways from the Hyde Park numbers:
- Appeals aren't guaranteed wins. Most appeals didn't result in a change — a realistic expectation matters going in.
- Property class shapes the odds. Commercial classes saw far higher success rates than residential ones.
- Reductions are still meaningful. Even at a moderate success rate, a win can lower your assessed value — and your bill.
