Data provenance — public records only
- Portland / Multnomah County — Regional taxlot service (owner names, mailing addresses, floors, building areas, and the last recorded sale with price). Oregon publishes no bulk transaction history and Portland no business-licence roll, so sales are last-per-parcel and no tenant layer exists.
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.
