Data provenance — public records only
- Boston — MassGIS L3 standardized parcels with the city assessment roll (owner names, mailing addresses, stories, assessed values, last recorded sale). Boston publishes no universal business roll, so no tenant layer is possible from public records here.
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.
