Boone County is now in Censum's Illinois expansion workstream.
The current validation layer includes **24,259 Boone County parcel rows** and **24,259 geometry rows**. That is enough to support local education and data QA, but it is not the same as live Censum checker coverage.
The caveat matters. Boone is in validation, not fully open for instant screening. In plain English: we can learn from the county data shape now, but homeowners should join intake rather than assume a finished score is ready today.
Quick read for Boone homeowners
- **Status:** validation coverage, not live instant screening.
- **Best first move:** check the property record for physical facts before debating value.
- **Common mistake:** waiting for a tax bill and then discovering the assessment appeal window is already the real issue.
- **Where Censum helps:** collecting demand and preparing the evidence workflow while the county lane is validated.
Why Boone still deserves a post now
Boone homeowners do not need to wait for a full launch to start checking the basics.
The appeal file starts with the property record. If the record has the wrong building size, class, land, improvement, or site information, that can change the whole case. A model can eventually help spot likely issues, but a homeowner can already do the first check.
The practical first pass is:
- Pull the assessment notice.
- Pull the property record.
- Check physical facts before debating value.
- Decide whether the issue is fair cash value, uniformity, or a record error.
- Confirm the current-year deadline and evidence rules before filing.
The appeal is about assessment, not the tax bill
Illinois assessment appeals are not a complaint about the final bill. The value question comes first. If the assessment is wrong, the bill may eventually change. If the tax rate or local levy is the problem, the Board of Review usually is not the right tool.
That distinction keeps homeowners from wasting their one shot on the wrong argument.
What Censum is watching
For Boone, the next useful step is improving the assessment-record layer and validating the full screening workflow. Until that is clean, the safest homeowner-facing path is intake, not "instant score."
That still has value. It lets Censum capture demand, educate homeowners, and prepare the screening lane without overstating readiness.

Censum note
Censum is building county-specific screening carefully. Boone County is in the validation layer, and homeowners should use this as a record-check and launch-intake guide until full coverage is ready.
Next step
If you own in Boone County, join intake and start with the record-card check. If the record is right, your next question is whether the value or uniformity evidence is strong enough to justify an appeal.
