North Chicago Township 2026 Property Tax Appeal Evidence Packet

How North Chicago Township Homeowners Win Assessment Reductions

When reviewing a residential appeal in North Chicago Township, analysts at the Cook County Assessor evaluate two primary statutory grounds:

• Lack of Uniformity: Comparing your home's Building Assessed Value per square foot ($/sq ft) against 3 to 6 similar properties in the exact same Assessor Neighborhood Code and Property Class (e.g., Class 2-03 one-story, Class 2-04 larger one-story, Class 2-05/2-06/2-07 two-story, Class 2-11 two-to-six flat, or Class 2-95 townhome).
• Overvaluation (Recent Comparable Sales): Demonstrating that recent arm's-length residential sales in your neighborhood support a lower fair market value than the Assessor's implied valuation.

With North Chicago Township's typical composite tax rate of approximately 6.69% and the Cook County state equalization factor of 3.0355, every $5,000 reduction in Assessed Value lowers your annual property tax bill by roughly $1,015/year.
