Only 6 fields on this public REST endpoint: ASSESSMENT_NO, SITE_ADDRESS, YEAR_BUILT, NBR_BEDROOMS, SHAPE, OBJECTID. Owner name is NOT available on this layer. The public REST endpoint is geometry + parcel ID + limited building characteristics only. Owner data lives in the OCPA (Orange County Property Appraiser) portal at ocpa.com and is not exposed via public REST. A second service at ocgis4.ocfl.net/arcgis/rest/services/Public_Dynamic/MapServer exists for county facilities but not full parcel attributes.

Orange County's Parcels layer exposes a parcel identifier (Assessment Number (Parcel ID)) and address fields (Site Address). Use it for address-to-PIN lookups and identifier queries. 2 of 4 listed fields accept queries; the rest are returned on read but not indexed for search. Served as an ArcGIS MapServer layer, which supports query operations but not write operations; last verified 2026-05-11.
/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 Orange County actually publishes, not what you might expect from a national standard (there isn't one).
For background, see What is an APN?
www.ocgis.com serves Orange County, Florida 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 Orange County's MapServer layer on 2026-05-11. 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.
Orange County's layer is hosted by the county on www.ocgis.com. Public ArcGIS endpoints rarely rate-limit individual reads, but www.ocgis.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.
