Hyde Park is the fourth Chicago township the Board has opened this year, after Rogers Park, Lakeview and West Chicago. As of Nov. 11, 2026 its schedule lists no Board of Review dates for Lake, Jefferson, North Chicago or South Chicago townships. For every township’s dates, see our fall 2026 appeal deadlines post.
Which part of Chicago is Hyde Park Township?
The township is much larger than the Hyde Park neighborhood. The Assessor describes it as bounded by State Street on the west, Pershing Road on the north, the lakefront on the east and 138th Street on the south. If you are not sure which township your home is in, the Assessor says you can find it on your reassessment notice or in your property details on its website [8].
Do I have to appeal with the Assessor first?
No. The Board’s FAQ says it is not bound by the Assessor’s final determination and that you are at no disadvantage if the Assessor granted or denied a reduction [4]. The Board’s Nov. 5 release calls it the second level of appeal [2], and its FAQ describes it as a separate agency independent of the Assessor [4]. If you disagree with its decision, the FAQ says you can go on to the Illinois Property Tax Appeal Board or the Cook County Circuit Court.
How do I file a Board of Review appeal?
- Online at cookcountyboardofreview.com (the Board’s appeal portal).
- In person at the Board of Review, 118 N. Clark St., Chicago, Monday to Friday, 9 a.m. to 5 p.m.
- Through an attorney or authorized tax representative, if you choose. Owners can represent themselves on property held in their own name, such as their condo or small apartment building; property held by a corporation such as an LLC must be represented by an attorney, per the FAQ [4].
The Board’s phone number for questions is 312-603-5542. Our guide to appealing a Chicago property tax assessment covers what evidence helps and when an appeal is worth filing.
Is Hyde Park Township being reassessed in 2026?
No. The Assessor says the south and west suburbs are reassessed in 2026 and that properties in the north suburbs and the City of Chicago are not being reassessed this year. Hyde Park Township was last reassessed in 2024. You can still appeal the 2026 value without a new reassessment.
In that 2024 reassessment, the Assessor compared 2023 median sale prices with its 2024 median estimated market values for the township. Both columns cover Hyde Park Township and the same property type; the sale prices are from calendar 2023 and the estimates are for tax year 2024. Total assessed value in the township rose 38%, and the 2024 Assessor appeal deadline was Sept. 11, 2024.
| Property type (Hyde Park Township) | 2023 median sale price | 2024 Assessor median estimate |
|---|---|---|
| Single-family homes | $161,000 | $127,000 |
| Condos | $172,000 | $184,000 |
| Small apartment buildings | $267,000 | $206,000 |
These are township-wide medians. Whether your own value is high depends on your property and recent sales of similar ones, which is what an appeal looks at.
How does an appeal affect the tax bill?
The Board’s FAQ says the first-installment bill is 55% of the previous year’s total bill, so it is not affected by a pending appeal [4]. The second installment is calculated only after the Board finishes all 38 townships. A lower assessment may lower the bill, but exemptions, levies and tax rates also matter, so a reduction does not guarantee a lower bill or a refund [4]. If you are buying in the township, see how to estimate a Chicago property tax bill and make sure the Homeowner Exemption is in your name after you move in.
