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.

Duval County is consolidated with the City of Jacksonville (consolidated city-county). The CityBiz/Parcels MapServer is the authoritative parcel layer for the consolidated jurisdiction. 70+ fields confirmed including RE (real estate number / parcel ID), LNAMEOWNER, LNAME2, STREET_NO, ST_NAME, ADDRCITY, MAILADDR1/2/3, MAILCITY, MAILSTATE, MAILZIP, PUSE (property use), DESCPU (description), ZIPCODE, FLD_ZONE, ACRES, TOT_LND_VA, TOT_BLD_VA, TOT_IMPR_V, SALESLDD/MM/YY, CAMA_VAL, CURREXEMPT. Owner search uses LNAMEOWNER field (last-name-first format). Verified 2026-05-15: SMITH returns Jacksonville addresses. The Florida Department of Revenue statewide cadastral layer is also registered for this county, filter with CO_NO=26, as a second endpoint. The county's own layer is queried first: it is refreshed far more often than the annual state tax roll, and the statewide layer refuses a query carrying a small resultRecordCount, which is the shape a billed lookup sends.

Duval County's Parcels layer exposes a parcel identifier (Real Estate Number (Parcel ID)), owner names (Owner Name), and address fields (Street Name). Use it for owner-name lookups and address-based parcel searches. 3 of 9 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 2026-05-15.
/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 Duval County actually publishes, not what you might expect from a national standard (there isn't one).

maps.coj.net serves Duval 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 Duval County's MapServer 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.
Duval County's layer is hosted by the county on maps.coj.net. Public ArcGIS endpoints rarely rate-limit individual reads, but maps.coj.net 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.
