Washoe County's Parcels layer exposes a parcel identifier (Assessor Parcel Number), owner names (Owner First Name, Owner Last Name), and address fields (Situs Street Name, Situs City). Use it for owner-name lookups and address-based parcel searches. 5 of 17 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 2026-05-15.
/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 Washoe County actually publishes, not what you might expect from a national standard (there isn't one).

wcgisweb.washoecounty.us serves Washoe County, Nevada 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 Washoe County's MapServer layer on 2026-05-15. 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.
Washoe County's layer is hosted by the county on wcgisweb.washoecounty.us. Public ArcGIS endpoints rarely rate-limit individual reads, but wcgisweb.washoecounty.us 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.
