This is DeKalb County, Illinois (county seat Sycamore, home to Northern Illinois University in DeKalb city), not to be confused with DeKalb County, Georgia (Atlanta metro, FIPS 13089). The Illinois county (FIPS 17037) is an outer-collar county roughly 60 miles west of Chicago. Hosted on ArcGIS Online (services7.arcgis.com), the county's WAB viewer config points at this FeatureServer as the backing data layer. 27 fields total including Parcel_Number, Owner, SiteAddress, MailingAddress, tax_code, net_taxable_value, Zone_Code, and QTAS/Compass hyperlinks. Owner-name search by UPPER() LIKE on the Owner field works directly; no token required. The public-facing viewer at spatial.dekalbcounty.org uses VertiGIS/Geocortex as its front-end but queries the same FeatureServer. DeKalb County GIS is administered by the county's Information Management Office (gis@dekalbcounty.org). Owner and TaxBillMailedTo are distinct fields. TaxBillMailedTo reflects the current billing addressee, which may differ from the recorded owner in cases involving trusts or recent transfers.

DeKalb County's Parcels layer exposes a parcel identifier (Parcel Number), owner names (Owner Name), and address fields (Site Address, Mailing Address). Use it for owner-name lookups and address-based parcel searches. All 5 listed fields accept queries. Served as an ArcGIS FeatureServer layer, so edits and applyEdits operations are technically exposed (read access only is published here); last verified 2026-05-15.
/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 DeKalb County actually publishes, not what you might expect from a national standard (there isn't one).

services7.arcgis.com serves DeKalb 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 DeKalb County's FeatureServer 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.
DeKalb County's layer is hosted on Esri ArcGIS Online. Public ArcGIS endpoints rarely rate-limit individual reads, but services7.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.
