Where is North Chicago Township?
Despite the name, North Chicago Township is inside the city, not the suburb of North Chicago in Lake County. The Assessor’s Office describes it this way (September 21, 2021 release):
- South and west: the Chicago River.
- North: Fullerton Avenue.
- East: Lake Shore Drive, while also taking in Navy Pier and Streeterville.
If your home is close to one of these edges, confirm your township with the Assessor’s Office before relying on the November 24 date.
Is North Chicago Township being reassessed in 2026?
No. The Assessor’s 2026 calendar says the south and west suburbs are reassessed in 2026, while City of Chicago properties are reassessed only if an individual property has significant changes. Cook County reassesses each township once every three years, and North Chicago Township was last reassessed in 2024.
The Assessor’s 2024 figures for the township show how its estimates compared with actual sale prices. These are the values an appeal this year would be measured against.
| North Chicago Township, 2024 reassessment | Median sale price, 2023 | Assessor median estimated market value, 2024 |
|---|---|---|
| Condominiums | $330,000 | $378,000 |
| Single-family homes | $1,355,000 | $1,483,000 |
| Small apartment buildings | $1,450,000 | $1,492,000 |
In each class the Assessor’s 2024 median estimate was higher than the 2023 median sale price. That is a township-wide comparison of two different measures, not a sign that any single property is over-assessed; whether yours is depends on its own characteristics and value.
Is a North Chicago Township appeal worth filing?
The Assessor’s Office suggests considering an appeal if the property characteristics on your notice are wrong, or if the estimated market value is well above what you think the property would sell for. If the characteristics are correct and the estimate is within 10% of what you think your home is worth, the Assessor says an appeal is unlikely to change your bill much.
Evidence must be filed at the same time as the appeal. For overvaluation, the Assessor points to recent closing statements and purchase prices of similar homes; for wrong characteristics, dated photos or a property deed. Appraisals must be USPAP compliant. You do not need to submit comparables for a uniformity appeal, because the Assessor’s analysts review them. Condominium owners will find a separate Condos & Co-Ops section on the Assessor’s appeals pages.
How do you file, and do you need to hire anyone?
Filing is free and can be done online in as little as 20 minutes, according to the Assessor’s Office, which says you do not need to hire anyone. Paper forms are available if you cannot file online. Mailings from private tax firms offering to appeal for a fee do not come from the Assessor’s Office.
What does this mean if you just bought, or are buying, in North Chicago Township?
- If you bought recently: your closing statement is the kind of evidence the Assessor names for an overvaluation appeal. New owners also need to apply for the Cook County homeowner exemption.
- If you are shopping for a condo: check the unit’s current assessment and recent tax bills to estimate your Chicago property tax bill, and see what to check when buying a condo in Chicago.
- If you miss November 24: the Assessor says you may appeal in a following year when your township is open, and the Board of Review is a separate second step once it announces North Chicago’s window.
