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.
