Building size (SF)

McHenry, Kane and DuPage county records carry no building size, so a size filter leaves those three counties out.

Lot size (acres)

Year built

Most Cook County buildings have a year on file; most Lake County buildings do not, so a year filter leaves out most of Lake.

Sale history County zoning contains

Unincorporated Lake County only. Inside a village, the village’s own zoning map governs; the detail panel links to it.

· updated September 30, 2026

Public record says what a building is. Not what it is worth.

It cannot tell you what it would sell for today, who is looking for one like it, what the unit down the street actually leased for, or whether the owner would sell. That part is a conversation.

Commercial property on file, town by town

Each town in the lookup: how many commercial, industrial and vacant commercial properties it holds, the building area recorded on them, the median computed property tax (Lake County parcels, shown when at least five carry a figure) and how many carry a usable sale price. Tap a town to search it.

Questions

What does the Commercial Property Lookup show?

Jason Bitton's database of 66,644 commercial, industrial and mixed-use properties and vacant commercial or industrial parcels in Lake, McHenry, Kane and DuPage counties, Illinois, plus 56 towns in north, northwest and west suburban Cook County: building size, land area, year built (Cook), the county valuation, a computed property tax for Lake County parcels, the last usable sale, and the site: FEMA flood zone (Lake and Cook), mapped wetland (Lake County), TIF district and the O'Hare noise contour (Cook). McHenry, Kane and DuPage county records carry no building size or flood zone; of the three only DuPage publishes an assessed value (the valuation shown is that times three, as in Lake County), and DuPage's records name no TIF district. Filter by type, building size, lot size, year built and site, and see the results on a map. Tap a result to see how it compares with its own town.

How is the property tax figure calculated?

For Lake County parcels: the 2025 assessed value times the 2025 tax rate for the parcel's tax code. It is a computed figure, not a tax bill, and a figure that does not fit the building on file is left out. Cook, McHenry, Kane and DuPage parcels show no tax figure.

Why is the Lake County valuation three times the assessed value?

Illinois sets a Lake County assessed value at one third of the assessor's market opinion, so the lookup multiplies it by three to put Lake and Cook on the same footing. Cook County publishes its assessor's market value directly.

Is the county valuation what my building would sell for?

No. It is the assessor's own market estimate, not an appraisal and not a listing price. In our checks against recorded sales since 2022 (1,455 in Lake County, 1,674 in Cook and 1,880 in DuPage), the Lake County valuation shown here has run about 75% of the sale price, Cook valuations about 93% and DuPage valuations about 89%, so treat the Lake figure as conservative. For a real number, ask Jason for a confidential opinion of value.

What does a blank sale price mean?

It means no usable price is on file for that property, not that it never traded. Sales that were not a clean market sale, or whose price does not fit the building on file, are left out.

Which buyers and tenants appear when I open a property?

Active buyer and tenant requirements Jason is working on whose target area, property type and minimum size may fit that parcel. They are anonymous and come from his public requirement pages. A match means may fit, not a buyer for that building.

Does the lookup show who owns a property?

No. No owner names and no tenant information are published here.

Built by Jason Bitton RE/MAX Commercial from public property records, then cleaned, classified and checked. Updated September 30, 2026; assessed values and county valuations are for the 2025 assessment year. A county valuation is the assessor’s own estimate: not an appraisal, not a listing price and not an opinion of value. Computed tax is not a tax bill. Records can be wrong or out of date, so check anything you rely on. No owner names, parcel numbers or tenant information are published here.
