Next window: the Assessor and Board of Review each open once a year; check your property now so you're ready.
Check your Evanston property freeThe North Triad schedule placed Evanston Township's latest reassessment in 2025, with the next scheduled for 2028. A property's township controls that timing rather than the municipality appearing in its mailing address. Independently of the reassessment cycle, the Board of Review provides an Evanston Township window every year.
Evidence to review
- Use the county record to separate above-grade building area from basement or other space before comparing homes by size.
- For older housing, line up construction era, exterior type, and documented additions before treating a recent sale as a close match.
- Consider rail, traffic, or commercial exposure on both parcels and explain any location difference that a map distance does not capture.
- Create a dated photo sequence when a defect has changed over time, and label the part of the property shown in each image.
