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).

services.arcgis.com serves Philadelphia County, Pennsylvania parcels over public ArcGIS REST, but, like most county servers, it may not send the CORS headers a browser needs for a cross-origin fetch. If a direct browser call fails, the layer still works from curl, Postman, or a server-side script; the UrbanKit parcel lookup tool proxies the request, so a search that succeeds there confirms the layer is genuinely public.
We last verified Philadelphia County's FeatureServer layer on 2026-05-11. County GIS teams move services without notice, so if you hit a fresh 404, tell us and we'll re-check. Atlas entries are re-verified on a rolling basis.
Philadelphia County's layer is hosted on Esri ArcGIS Online. Public ArcGIS endpoints rarely rate-limit individual reads, but services.arcgis.com can throttle heavy automated traffic at the host level. Page through results with resultOffset / resultRecordCount and request only the fields you need. There's no API key and no charge from the county.
