Hillsborough County Property Appraiser (HCPA) public parcel layer at gis.hcpafl.org, 'WebParcels_NonConfidential', ~527,844 parcels exposing Owner1/Owner2 (owner name), folio (parcel ID), strap (alternate key), and FullAddress. Owner search via UPPER(Owner1) LIKE works; field names are CASE-SENSITIVE (Owner1, folio, FullAddress). Records flagged Confidential (state address-confidentiality program) have owner names suppressed. Replaced the prior SWFWMD regional water-district layer (2026-06-08). NOTE 2026-06-27: query endpoint responds in 13-35s (server-side slowness); the liveness check at 12s timeout always flags this FAIL but the endpoint IS live. Metadata returns immediately. If the liveness checker timeout is raised above ~30s for this endpoint, it will pass.

Hillsborough County's WebParcels_NonConfidential layer exposes parcel identifiers (Folio Number (Parcel ID), STRAP (alternate parcel key)), owner names (Owner Name, Owner Name 2), and address fields (Site Address). Use it for owner-name lookups and address-based parcel searches. 5 of 8 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 2026-06-27.
/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 Hillsborough County actually publishes, not what you might expect from a national standard (there isn't one).

gis.hcpafl.org serves Hillsborough 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 Hillsborough County's MapServer layer on 2026-06-27. 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.
Hillsborough County's layer is hosted by the county on gis.hcpafl.org. Public ArcGIS endpoints rarely rate-limit individual reads, but gis.hcpafl.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.
