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).

Many county servers allow public reads but block browser cross-origin requests. The UrbanKit parcel lookup tool fetches directly from your browser; if it works there, the layer is technically public. For your own integration, you may need a same-origin proxy or server-side fetch.
Possibly — counties move services without warning. We re-verify entries weekly and flag stale ones. If you're seeing a fresh 404, please let us know and we'll update the listing.
Most are. Public ArcGIS layers don't typically rate-limit individual reads, but heavy programmatic use can trigger throttling at the host level. Be respectful — query what you need.
