From the General Services Administration's monthly lease inventory: the rent the federal government actually pays, the square feet behind it, the dates, and the renewal options remaining. A fully serviced lease includes services and utilities, so it is not comparable to a net rent. This is one tenant, not the market. Federal space is often fitted for a specific agency and leased on government terms, so treat it as a real, checkable data point rather than an asking rent for the building.

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.
  • U.S. General Services Administration — lease inventory — Active federal leases published monthly: annual rent actually paid, rentable square feet, effective and expiration dates, termination right, renewal options remaining and the lessor's name.

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.
