Data provenance — public records only
- New York City — Department of City Planning PLUTO extract and Department of Finance rolling sales. The city publishes no owner mailing address, so landlord portfolios cannot be grouped here, and its business licences cover regulated trades rather than office tenants.
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.
