Cass County's CountyParcels layer exposes parcel identifiers (GIS Parcel ID, Parcel Identification Number, Dash PIN), owner names (Owner Name), and address fields (Property Address). Use it for owner-name lookups and address-based parcel searches. 5 of 15 listed fields accept queries; the rest are returned on read but not indexed for search. Served as an ArcGIS MapServer layer, which supports query operations but not write operations; last verified 2026-06-20.

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 Cass County actually publishes, not what you might expect from a national standard (there isn't one).

gisweb.casscountynd.gov serves Cass County, North Dakota 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 Cass County's MapServer layer on 2026-06-20. 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.
Cass County's layer is hosted by the county on gisweb.casscountynd.gov. Public ArcGIS endpoints rarely rate-limit individual reads, but gisweb.casscountynd.gov 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.
