Data provenance — public records only
- Seattle / King County — King County Assessor bulk extracts and Seattle open data. Washington law restricts commercial use of lists of individuals, so this metro is built without personal names by design: the county's name-stripped account file provides mailing addresses (portfolios group by mailing cluster, unnamed), sales show price and date but never buyer or seller, and tenants are business licence trade names.
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.
