https://maps.nevadacountyca.gov/arcgis/rest/services/web_public/parcel_mail_situs_external/MapServer/0Field by field, whether any endpoint we index for Nevada 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.

Nevada County, California (FIPS 06057; county seat Nevada City; Grass Valley, Truckee, Penn Valley) serves its parcels from the county's own ArcGIS Server (ArcGIS 11.4) at maps.nevadacountyca.gov. The record uses web_public/parcel_mail_situs_external MapServer layer 0: 68,134 rows on 2026-11-01 for 64,349 distinct APNs, because a parcel with more than one site or mailing address is drawn as overlapping polygons (the service description says so). The layer is attached to the Assessor's roll bi-monthly; RollYear is 2026. APN is 12-digit text (005040055000) and APN_FORMATTED the hyphenated 9-digit form (005-040-055); compare both as strings. ADDRESS is the situs street line (non-blank on 67,903 rows) with PostOffice and ZipCode; the owner mailing address is MailingAddress (non-blank on 67,060 rows) with MailPO_Zip. Also UseCode, ZONING, GPDES, JURISDICTION, LegalDescription, AssessedAcreage, the land, improvement, fixture and personal-property values, exemption and gross and net roll values, TaxAreaCode and REPORT_URL. NO OWNER NAME: the service description reads 'Identical to internal version but owner name is hidden', and the county GIS FAQ says the GIS Division has been instructed not to distribute owner name to any entity, citing Gov. Code 7928.205 as amended by AB 1785; the same FAQ says owner mailing address is available in the data download and the My Neighborhood export. MAILING ADDRESS SERVED: UrbanKit asked the county on 2026-11-01 whether it may show the owner mailing address without names, and on 2026-11-02 the county's GIS Division confirmed that we may use the publicly available data from its Open Data Portal as described, as long as we abide by the CC BY 4.0 licence; the registered layer's mailing columns (MailingAddress, MailPO_Zip) are served, and the county asked us to show its disclaimer (it is in the credit line). maxRecordCount 2000 with pagination, Web Mercator (wkid 102100), CORS reflects the caller's Origin.

Nevada County's PARCEL_OWNER_MAIL_SITUS_SDEVW layer exposes parcel identifiers (Assessor Parcel Number (APN, 12 digits, text), APN (hyphenated, 9 digits)) and address fields (Situs Address). Use it for address-to-PIN lookups and identifier queries. 3 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 2026-11-01.
/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 Nevada County actually publishes, not what you might expect from a national standard (there isn't one).

maps.nevadacountyca.gov serves Nevada County, California 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 Nevada County's MapServer layer on 2026-11-01. 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.
Nevada County's layer is hosted by the county on maps.nevadacountyca.gov. Public ArcGIS endpoints rarely rate-limit individual reads, but maps.nevadacountyca.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.
