South Chicago Township Residential Property Tax Appeal — What Wins for Homes & Condos
South Chicago Township covers Chicago's Southeast Side — South Shore, South Chicago, the East Side, Hegewisch, Calumet Heights, and Avalon Park. It was reassessed in 2024 as part of the City of Chicago's cycle, and isn't due again until 2027. The 2024 appeal data shows a wide split: single-family homes won 20.4% of appeals, while condominiums — the large majority of filings here — won just 9.0%. Here's what the data shows, what wins, and how to file.

The 60-Second Version
- South Chicago was reassessed in 2024 (City of Chicago cycle) and isn't due again until 2027 — but the value set in 2024 carries through the whole cycle.
- You can appeal every year, not just in reassessment years. The 2025 annual round has already closed; the next windows are 2026 and 2027.
- Single-family homes beat condos: 20.4% of single-family appeals won, more than double the 9.0% condo rate.
- This is a condo township. Condos were the large majority of appeals (about 40,000), which pulls the overall number down.
- Two- and three-flats did best among the higher-volume home classes (27.5%); townhomes were the weak spot at 6.5%.
If you own a home or condo in South Chicago Township, the 2024 reassessment set a value that follows you until 2027. The good news: you don't have to wait that long to act. Cook County lets you appeal every year, and the 2024 results show clearly which kinds of homes had the strongest case here.
01 · How your bill worksHow your tax bill is calculated
Every Cook County tax bill follows the same formula:
Residential property is assessed at 10% of the Assessor's estimated market value. An appeal targets that assessed value — if it's too high relative to comparable homes, a reduction lowers the taxable base that flows through the rest of the calculation. In a reassessment year like 2024, that value is freshly set and generally carries forward until the next reassessment, so getting it right matters for the whole cycle.
02 · What the data showsWhat the 2024 reassessment showed for homes & condos
South Chicago owners filed about 48,000 appeals in 2024, and 12.3% won overall — but that average is dominated by condos. Single-family homes won 20.4%, while condominiums won just 9.0%. Here's how the main residential classes performed:
| Class | What it generally represents | Appeals | Success |
|---|---|---|---|
| 2-11 | Two- or three-flat (small residential) | 1,431 | 27.5% |
| 2-03 | One-story home, 1,000–1,800 sq ft | 446 | 27.4% |
| 2-78 | Two-or-more story home (newer) | 507 | 14.0% |
| 2-99 | Condominium | 40,154 | 9.0% |
| 2-95 | Townhome / row house | 1,161 | 6.5% |
The pattern: two- and three-flats (Class 2-11) and one-story homes (2-03) led, both near 27%. Condominiums (2-99) were by far the largest group — about 40,000 of the township's appeals — but won only 9.0%, and townhomes (2-95) were the weak spot at 6.5%.
03 · The condo paradoxWhy condos won least
South Chicago — especially the South Shore lakefront — is full of condominium buildings, and condos made up the large majority of the township's appeals. Yet they won the least. That's the familiar "condo paradox": condo values are set consistently across a building, so it's hard to argue a single unit is mispriced relative to its neighbors — there's little non-uniformity to point to. It's not that condo appeals can't win; the winning ones lean on specific evidence: sales within the same association, or unit-level differences (a lower floor, no view, dated condition) the model didn't capture. The average winning condo cut here was modest — about $2,000 in assessed value — while single-family winners averaged closer to $12,900.
04 · What winsWhat actually wins a South Chicago home appeal
Homes are valued mostly on comparable sales, so residential appeals are won on comparison — not on frustration with the bill. Three grounds carry the most weight:
- Lack of uniformity (the strongest residential argument). If comparable homes near you — similar size, age, style, and lot — are assessed for less per square foot than yours, your assessment is "non-uniform" and should be brought in line.
- Overvaluation. If recent sales of similar nearby homes — or a recent purchase or appraisal of your own home — come in below the Assessor's implied market value, you can argue the assessment overstates what your property is worth.
- Factual error in your record. Too much square footage, a finished basement that isn't finished, an incorrect unit or room count — correcting the record can lower the assessment on its own.
05 · What it's worthWhat a reduction is worth
South Chicago's composite tax rate runs around 6.6% — lower than the suburbs, as City of Chicago rates generally are. A reduction in assessed value translates into annual savings that repeat for as long as the lower value holds:

06 · How to fileHow to file your South Chicago appeal
- Find your PIN and pull your assessment. Confirm the current value and the characteristics the Assessor has on record for your home, using your 14-digit Property Index Number.
- Check the calendar for South Chicago's window. Confirm the current-year "open" and "last file" dates on the Assessment & Appeal Calendar. Don't file before the township opens.
- Assemble your evidence. Comparable homes assessed for less, any recent sale or appraisal of your home, and photos or records correcting anything wrong in your property description.
- File online with the Assessor during South Chicago's open window, then again with the Board of Review — an independent body that opens after the Assessor's window, even if the Assessor reduced you only partially or not at all.

07 · Where South Chicago standsYou can appeal every year — watch for the 2026 window
South Chicago is a City of Chicago township, reassessed in 2024, so its values are generally set until the next reassessment in 2027. Its 2025 annual appeal window has already closed. But the right to appeal isn't limited to reassessment years — Cook County lets you challenge your assessed value every year. South Chicago's 2026 dates hadn't been published as of this writing; when the window opens, you can file again, which is especially worth doing if you didn't appeal in 2024 or your result didn't go far enough.

Can I appeal in South Chicago if it isn't a reassessment year?
Yes. South Chicago was last reassessed in 2024 and is next due in 2027, but Cook County allows an appeal every year. Its 2025 window has closed; the next opportunities are 2026 and 2027. Confirm South Chicago's current-year window before filing.
How did homes and condos do in South Chicago's 2024 reassessment?
Single-family homes won 20.4% of appeals and condominiums 9.0% — homes beat condos by more than two to one. Single-family winners averaged about a $12,900 reduction in assessed value; condo winners about $2,000. Townhomes (Class 2-95) were the weak spot at 6.5%.
Why did condos win the least?
Condos are the large majority of appeals here, and condo values are set consistently across a building, leaving little non-uniformity to argue. Winning condo appeals use sales within the same association or unit-specific differences (floor, view, condition) the Assessor's model didn't capture.
How much could a reduction save me?
South Chicago's composite tax rate runs around 6.6%. As a rough guide, a $5,000 cut in assessed value translates to roughly $1,000 a year, and it repeats for as long as the lower value holds. Estimates exclude exemptions and vary by tax code.
Does filing an appeal risk raising my taxes?
An appeal is a request to review your assessed value. If it isn't reduced, your assessment stays as it was. You can also pursue a separate, second-level appeal at the Board of Review after the Assessor.
