15 fields confirmed including parcelid, owner1, owner2, address, brt_id (BRT = Board of Revision of Taxes, now OPA = Office of Property Assessment), bldg_code, bldg_desc, gross_area, pin, tencode. Owner query tested and confirmed. The parcelid here is an integer OBJECTID; the brt_id (9-digit string, e.g. '171006315') is the stable OPA/BRT account number used in the assessor system. For deeper property assessment data (market value, sale price, exemptions, zoning), the OPA Properties dataset at opendataphilly.org/datasets/opa-properties-public has 78+ fields but is distributed as a CSV/API download rather than a REST FeatureServer with geometry. Philadelphia parcels are city-county unified (Philadelphia City = Philadelphia County).

Philadelphia County's PWD_PARCELS layer exposes a parcel identifier (Parcel ID), owner names (Owner Name (Primary), Owner Name 2), and address fields (Street Address). Use it for owner-name lookups and address-based parcel searches. 5 of 8 listed fields accept queries; the rest are returned on read but not indexed for search. Served as an ArcGIS FeatureServer layer, so edits and applyEdits operations are technically exposed (read access only is published here); last verified 2026-05-11.
/query?where=…&outFields=*&f=jsonto the URL. The sample query above is a working example you can paste into a browser tab to see the raw JSON response.Counties publish parcel data through their own ArcGIS Server installations, each with its own schema. One county uses APN, another uses PIN, a third uses PARCEL_ID. Some expose owner names; others keep them on a separate assessor's portal. The searchable fields list above reflects what Philadelphia County actually publishes — not what you might expect from a national standard (there isn't one).
For background, see What is an APN?
Many county servers allow public reads but block browser cross-origin requests. The UrbanKit parcel lookup tool fetches directly from your browser; if it works there, the layer is technically public. For your own integration, you may need a same-origin proxy or server-side fetch.
Possibly — counties move services without warning. We re-verify entries weekly and flag stale ones. If you're seeing a fresh 404, please let us know and we'll update the listing.
Most are. Public ArcGIS layers don't typically rate-limit individual reads, but heavy programmatic use can trigger throttling at the host level. Be respectful — query what you need.
