Check your Lyons property freeFor property assessment, a mailing address does not set the calendar; the Cook County township does. Lyons Township was reassessed as part of the South Triad for 2026 and is next scheduled for reassessment in 2029. Even outside that reassessment cycle, the Board of Review opens a window for Lyons Township every year.

Evidence to review
- Locate the subject's assessment neighborhood in the county record before searching more broadly by mailing city, school district, or familiar local area.
- Compare corner, interior, and irregular lots with attention to shape, frontage, and other site differences that total square footage can obscure.
- Verify that basement finish, additions, and converted space are described on the same basis across the subject and candidate sales.
- Create a short condition log that dates each photograph and ties it to a room, building side, or repair document.
