Public ArcGIS MapServer endpoint for Lyon County parcel data. URL, supported fields, and a working sample query, copy it, or open it directly in the UrbanKit parcel lookup tool.
This page is the endpoint reference. If you came here to find a specific property, the Lyon County parcel search runs this same layer in your browser, no account and no API key.

https://gis.lyon-county.org/server/rest/services/Landbase/Land_Use_Parcel/MapServer/10Field by field, whether any endpoint we index for Lyon County answers it, and the evidence for each. We only call a field restricted when there is a stated reason we can cite. Everything else here is a fact about the services we index, not a claim about the law.

Lyon County, Nevada (FIPS 32019; Yerington, Fernley, Dayton, Silver Springs) publishes the Assessor's parcels on its own ArcGIS Server as Landbase/Land_Use_Parcel, MapServer layer 10 'Land Use -- Parcel': 35,343 parcels on 2026-10-08, maxRecordCount 2000, resultRecordCount accepted, answers any Origin with Access-Control-Allow-Origin set to the caller. 35,159 rows (99.5%) carry an owner and 33,164 a physical address. The owner is PANAME (alias 'Assessed Owner', 'LAST, FIRST' for individuals, for example DOE, JANE & JOHN); the situs is PHY_ADDR (123 EXAMPLE RD, blank on some vacant land); the owner mailing address is PMADD1 and PMADD2 plus PMCTST ('YERINGTON, NV') and PZIP; the parcel number is APN (003-034-01, dashed). The layer carries a great deal else (values, acreage, land-use and exemption codes, deed data, an owner email column PEMADR that we do not index). SLOW OWNER SEARCH: the layer has no index on PANAME. Measured 2026-10-08: UPPER(PANAME) LIKE '%SMITH%' (what the free Owner Lookup and Parcel Lookup tools send) took 13 to 15 s and returned 347 rows, an anchored UPPER(PANAME) LIKE 'SMITH%' took 4.5 s and returned 309, APN equality and a PHY_ADDR prefix about 1 s, and a count over PHY_ADDR about 9 s. The tools set no client timeout, so a wildcard owner search normally completes but slowly; the sampleQuery uses the anchored form. Use LAST-name-first prefix terms for speed. Do NOT use Landbase/Parcels/MapServer/1 (about 43 s per query), and do not use the statewide Nevada water layer: its service description forbids sharing under NRS 250. The service's Python urllib default User-Agent is refused with HTTP 403 (any other User-Agent, or none, is served), so a script probing it from Python must send its own. License: the item's licenseInfo reads 'Accessible by the public.' and its accessInformation is 'Lyon County, NV Assessor's office'; no formal terms page was found, so licenseUrl is the county GIS site root.

Lyon County's Land Use -- Parcel layer exposes a parcel identifier (Parcel Number (APN)), owner names (Assessed Owner), and address fields (Physical Address). Use it for owner-name lookups and address-based parcel searches. 3 of 10 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 2026-10-08.
/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 Lyon County actually publishes, not what you might expect from a national standard (there isn't one).

gis.lyon-county.org serves Lyon 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 Lyon County's MapServer layer on 2026-10-08. 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.
Lyon County's layer is hosted by the county on gis.lyon-county.org. Public ArcGIS endpoints rarely rate-limit individual reads, but gis.lyon-county.org 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.
