Data provenance — public records only
- Philadelphia — Office of Property Assessment nightly roll (owner and mailing address on every parcel), Department of Records deed transfers with consideration and counterparties, and L&I business licences joined by OPA account. The universal Commercial Activity licence roll publishes no premises addresses, so occupancy shows regulated activities only.
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.
