Top 5 Decreases in Assessment Change

While most property classes increased, a few saw decreases of up to –50.08%, often due to market adjustments or building condition updates.

Even with a decrease, reviewing your property ensures your assessed value vs. market value remains accurate.

Why Assessments Increased in 2025

Changing Market Trends

South Chicago neighborhoods are evolving quickly. The property valuation in Cook County reflects higher demand near new developments like South Works and along 79th Street.

In some cases, sales of newly built or renovated homes inflated the overall neighborhood averages.

County Reassessment Process

The Cook County Assessor’s Office reassesses each Chicago township every three years. The 2025 cycle brought updated valuation models, factoring in new market sales, construction costs, and demand.

While this helps the County stay accurate, it can cause over-assessment if your property is compared to larger or remodeled homes nearby — which is why filing a Cook County property tax appeal is so important.
