Check your Schaumburg property freeSchaumburg Township extends beyond the village that shares its name, so the township—not the municipality in a mailing address—determines the assessment calendar. The township was reassessed with the North Triad for 2025 and is next scheduled for reassessment in 2028. A Board of Review window opens for Schaumburg Township every year, including non-reassessment years.

Evidence to review
- For a townhome or a home in a planned development, identify properties with the same ownership form and a similar role for common areas before comparing values.
- Check whether end units, interior units, or different floor plans have physical features that make a nearby transfer less comparable.
- Use the assessment neighborhood shown in county records to organize the search instead of assuming a shared school district or village name defines the comparison area.
- If condition affects the comparison, match dated photographs to specific defects and explain whether the selected sales show the same issue.
