Data provenance — public records only
- St. Louis City — City of St. Louis parcel databases (owner names, mailing addresses, situs, building areas, stories, assessed values) and recorded sales with price from Certificates of Value. No universal business roll, so no tenant layer.
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.
