https://gis1.hamiltoncounty.in.gov/arcgis/rest/services/HamCoParcelsPublic/FeatureServer/0Field by field, whether any endpoint we index for Hamilton 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.

Hamilton County IN (Indianapolis north suburbs, Noblesville, Carmel, Fishers, Westfield) is one of the fastest-growing counties in Indiana. HamCoParcelsPublic/FeatureServer/0 exposes 25+ fields including FMTPRCLNO (formatted parcel number, e.g., '10-11-04-00-00-019.000'), DEEDEDOWNR (full deeded owner), OWNNAME, OWNADDRESS, OWNCITY, OWNSTATE, OWNZIP, OWNCOUNTRY, LOCADDRESS, LOCHSENUMR, LOCSTRDIR, LOCSTRNAME, LOCSTRSUF, LOCCITY, LOCZIP, LEGALDESC, SECTIONNO, TOWNSHIP, RANGE, SUBDIVCODE, SUBDIVNAME, DEEDACRES, PROPCLASS, PROPUSE. Query confirmed live: UPPER(LOCADDRESS) LIKE '%MAIN ST%' returned a count of 719 on 2026-11-02. ORDINANCE FOUND 2026-11-02: the county's GeoHub Terms of Service quote Hamilton County Ordinance 11-26-07-B, Section 5, adopted under Indiana Code 5-14-3-3(e), that no person other than those authorized by the County may reproduce, store, grant access, deliver or sell any information obtained from any department or office of the County for commercial purposes, and the same text is the licence on the county's Parcels_Current GeoHub item. No copy of the full ordinance is online (the Commissioners' archive starts in 2009), so how authorization is granted is not known. COUNTY ANSWER 2026-11-02: we asked the county GIS Office (gis@hamiltoncounty.in.gov, listed on the GeoHub) for permission, and the same day it told UrbanKit Studio that county data may not be used behind a pay service, under the county's GIS terms of service and the ordinance above. Owner names and mailing addresses are therefore not served (restricted, with the county's citation attributed to it), and paid lookups for Hamilton County are off. Revisit only if the county says it has changed its terms. Hamilton County IN (FIPS 18057) must not be confused with Hamilton County OH (39061, Cincinnati) or Hamilton County TN (47065, Chattanooga).

Hamilton County's Parcels layer exposes a parcel identifier (Formatted Parcel Number) and address fields (Property Address). Use it for address-to-PIN lookups and identifier queries. 3 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 2026-05-15.
/query?where=…&outFields=FMTPRCLNO,LOCADDRESS,LOCCITY,PROPCLASS&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 Hamilton County actually publishes, not what you might expect from a national standard (there isn't one).

gis1.hamiltoncounty.in.gov serves Hamilton County, Indiana 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 Hamilton 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.
Hamilton County's layer is hosted by the county on gis1.hamiltoncounty.in.gov. Public ArcGIS endpoints rarely rate-limit individual reads, but gis1.hamiltoncounty.in.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.
