https://services5.arcgis.com/8y4r60VTvWj2wnDH/arcgis/rest/services/Parcels_Public_/FeatureServer/0Field by field, whether any endpoint we index for Mendocino 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.

Mendocino County, California (county seat Ukiah) publishes its county-wide assessor parcel layer from the County's own ArcGIS Online organisation, Mendocino County GIS (org 8y4r60VTvWj2wnDH, owner account gis@mendocinocounty.gov, hub gis.mendocinocounty.gov), as Parcels_Public_ FeatureServer layer 0 (Parcels). The service name really ends in an underscore. 62,051 parcels on 2026-10-06, covering the whole county; the layer's data was last edited 2026-06-08. Fields: APN (8-character text, e.g. 04608040), APNFULL (10 characters, e.g. 0460804000), BOOK, PAGE, BLOCK, PARCEL, BOOKPAGE, SOURCE, SITUS_ADD, SITUS_CITY, SITUS_ZIP, CLASS_CD, ACRES and GEN_PLAN. APN and situs address are searchable; compare APN as a string (APN='04608040'). THE LAYER PUBLISHES NO OWNER NAME and no owner mailing address, so an owner search returns nothing here; ownership by APN has to be asked of the County Assessor. SITUS_ZIP is often empty. CORS is open (Access-Control-Allow-Origin: *), maxRecordCount is 2000, capabilities Query and Extract, native spatial reference NAD83 California zone 2 (feet, wkid 2226).

The City of Ukiah's ArcGIS organisation (services3.arcgis.com/KYBJaItvh9UgViWU) also hosts two Ukiah-area clips of this data, an APN label layer and an Area of Interest assessor clip with an OWNER column (about 10,000 parcels); neither is county-wide, so neither is listed. Contact: gis@mendocinocounty.gov, (707) 234-6000. Verified live 2026-10-06: APN='04608040' returned 1 row (17601 INDIAN CREEK RD, PHILO, 1 acre) and UPPER(SITUS_ADD) LIKE '17601 INDIAN%' returned 2.

Mendocino County's Parcels layer exposes parcel identifiers (APN (8 characters, stored as text), APN, full (10 characters)) and address fields (Situs Address, Situs City). Use it for address-to-PIN lookups and identifier queries. 4 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 2026-10-06.
/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 Mendocino County actually publishes, not what you might expect from a national standard (there isn't one).

services5.arcgis.com serves Mendocino 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 Mendocino County's FeatureServer layer on 2026-10-06. 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.
Mendocino County's layer is hosted on Esri ArcGIS Online. Public ArcGIS endpoints rarely rate-limit individual reads, but services5.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.
