Every commercial and industrial parcel in Lake County, plus eight Cook County towns. Search any street and see what the county record says: building size, land, assessed value, a computed property tax (Lake County), and the last usable sale. Free, no signup.
County records as of September 7, 2026. Values are the 2025 assessment.
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.
Every town in the lookup, from the same county file: how many commercial and industrial parcels 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.

The county record for every commercial and industrial parcel in Lake County, Illinois, plus eight Cook County towns (Arlington Heights, Barrington, Elk Grove Village, Norridge, Northbrook, Palatine and Wheeling in northern Cook, and Bellwood in west Cook): building size, land area, the county valuation, a computed property tax for Lake County parcels, and the last usable sale. Bellwood's records carry no building area, value or sale. Tap a result to see how it compares with its own town.
For Lake County parcels only: the parcel's 2025 assessed value times the 2025 aggregate tax rate for its tax code, from the Lake County Clerk. It is a computed figure, not a tax bill. A computed figure above $8 per square foot is withheld. Cook parcels show no tax figure because this file carries no Cook tax rates.
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.
No. It is the assessor's own market estimate, not an appraisal and not a listing price. Measured against the recorded sales since 2022 in the county files, before this lookup's price check on industrial sales (1,236 Lake and 403 Cook sales), the Lake County valuation shown here, which is the assessed value times three, has run about 82% of sale price (the assessed value alone about 27%), and Cook valuations about 95%, so treat the Lake figure as conservative. For a real number, ask Jason for a confidential opinion of value.
It means no usable price is on file for that parcel, not that the building never traded. Lake prices are the last disclosed price in the county record; Cook prices leave out sales the Cook County Assessor flags as multi-parcel, nominal or similar transfers. For industrial parcels in both counties, a price under $10 or over $250 per square foot of recorded building area is left out too, the same check the Elk Grove Village Building Lookup uses.
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.
No. No owner names and no tenant information are published here.
County records as of September 7, 2026. Assessed values and county valuations are for the 2025 assessment year: Lake County’s tax year 2025 (paid in 2026) and the Cook County Assessor’s 2025 valuation. Lake County parcels and assessed values: Lake County GIS Division. Lake tax rates: Lake County Clerk, 2025 aggregate rate by tax code. Cook parcels, building areas and valuations: Cook County Assessor’s Office. Computed property tax is shown for Lake County only — this file carries no Cook tax rates, so no Cook tax figure is computed and none is shown; Cook parcels show year built and assessor value instead. Cook sale prices leave out sales the Cook County Assessor flags in its sales data (multi‑parcel, nominal and similar transfers); Lake prices are the last disclosed price in the county record. For industrial parcels in both counties, a price under $10 or over $250 per square foot of recorded building area is left out too. A blank means no usable price on record rather than a building that never traded. Cook parcels are typed industrial or commercial by the assessor’s building type where the record has one, and by the assessor’s class where it does not; Lake parcels by the assessor’s class. A negative building area or tax in the county file is treated as not on file. Lake tax figures are computed: the parcel’s 2025 assessed value times the 2025 aggregate rate for its tax code. They are not tax bills, and a computed figure above $8 per square foot is withheld. A building-area total adds up the recorded area of each matching parcel — a parcel is not a building, and 53% of Lake parcels have no recorded area. County valuation is the assessor’s own market estimate, not an appraisal and not a listing price. Cook publishes that figure directly; Lake publishes an assessed value that Illinois sets at one third of it, so the Lake figure here is the assessed value multiplied by three. Measured against the real recorded sales since 2022 in the county files, before this lookup's price check on industrial sales (1,236 Lake and 403 Cook sales), the Lake valuation shown here (the assessed value times three) has run about 82% of sale price, the assessed value alone about 27%, and Cook valuations about 95%, so treat Lake as conservative. No owner names and no tenant information are published here.
