Prices are the consideration recorded in Portland / Multnomah 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
- 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.
