Sale history
| Recorded | Price | Qualification | Source | Instrument |
|---|---|---|---|---|
| Feb 2017 | $85,920,250 | not rated | County roll | — |
Prices are the consideration recorded in Chicago / Cook County's public property records. Where a qualification code exists it is the assessor's judgement of whether a transfer was arm's length; transfers without one appear unrated rather than assumed clean. Whether a building is on the market today, and at what price, is not a public record and is not shown here — asking prices, listings and lease terms live in private commercial databases.

Data provenance — public records only
- Chicago / Cook County — Cook County Assessor parcel, commercial-valuation and sales datasets (owner names, mailing addresses, priced sales with buyer and seller); City of Chicago active business licences for occupancy. Licence addresses are street-level, and state-licensed professions are absent from the city roll.
Every fact on this page is drawn from the government records above — no listing sites, no scraped platforms, no third-party images. Facts from public records are uncopyrightable; each tenancy row carries its source and match confidence. Records can lag reality — a business-tax receipt or registration at an address is evidence of occupancy, not a lease confirmation.
