20 fields confirmed including PARNO, OWNNAME, MAILADD, OWNTYPE, AREATXT, IMPROVVAL, LANDVAL, PARVAL, PARVALTYPE, PARUSECODE, PARUSEDESC. Owner query returns real results with CNTYFIPS=057 confirming Hillsborough data. This endpoint is on the SWFWMD (regional water management district) server, which aggregates parcel data from multiple FL counties in a single LocationInfo MapServer (layer 71 of 80+). The Hillsborough County Property Appraiser's own REST server at gis.hcpafl.org does not expose a queryable public parcel layer — only their browser-based property search at gis.hcpafl.org/propertysearch/.

/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 this county actually publishes — not what you might expect from a national standard (there isn't one).
For background, see What is an APN?
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.
