Kane County is the highest-impression Illinois county in our GSC data; users search for 'kane county illinois gis rest api mapserver featureserver owner name'. The county migrated their GIS server from gis.co.kane.il.us to gistech.countyofkane.org in 2026. The old hostname now NXDOMAINs. The current layer is KanePINList/MapServer/0 (named Kane.DBO.Parcels_v2025), a snapshot of the active parcel polygon layer from the cadastral source. 35+ fields including PIN, TaxName, SiteAddress, MailingAddress, LegalDesc, UseCodeDescription, plus jurisdictional districts (Township, AirportDistrict, AmbulanceDistrict, etc.). Owner-style search uses the TaxName field (legal taxpayer name).

Kane County's Kane.DBO.Parcels_v2025 layer exposes a parcel identifier (Parcel Identification Number (PIN)), owner names (Taxpayer Name), and address fields (Site Address, Site City, Mailing Address). Use it for owner-name lookups and address-based parcel searches. All 5 listed fields accept queries. Served as an ArcGIS MapServer layer, which supports query operations but not write operations; last verified 2026-05-15.

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

gistech.countyofkane.org serves Kane County, Illinois 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 Kane 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.
Kane County's layer is hosted by the county on gistech.countyofkane.org. Public ArcGIS endpoints rarely rate-limit individual reads, but gistech.countyofkane.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.
