https://gis.lojic.org/maps/rest/services/LojicSolutions/OpenDataPVA/MapServer/1Field by field, whether any endpoint we index for Jefferson 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.
| Field | Status | Basis |
|---|---|---|
| APN | Answered | Documented in a field list on an endpoint we index. Not every row is populated. |
| Owner name | Not published | LOJIC's open-data parcel layer for Jefferson County carries a parcel id, a land record serial number and a parcel type only; it has no owner-name column, and the other Jefferson parcel service we found (Louisville Metro's New_AllParcels) carries an address and property class but no owner either. |
| Owner mailing address | Not published | No endpoint we index for this county documents this field, so a query cannot ask for it. That is a fact about the services we index, not a legal restriction, and not a statement that the county holds no such record. |
| Site address | Not published | No endpoint we index for this county documents this field, so a query cannot ask for it. That is a fact about the services we index, not a legal restriction, and not a statement that the county holds no such record. |

Jefferson County, Kentucky (Louisville; FIPS 21111; the county is consolidated with Louisville Metro). 'Jefferson County KY Parcels', layer 1 of LojicSolutions/OpenDataPVA on the Louisville/Jefferson County Information Consortium (LOJIC) server: 293,248 parcel polygons, maxRecordCount 2,000, pagination on, State Plane feet (outSR=4326 works), CORS reflects the request Origin. The layer carries only PARCELID (293,217 rows), LRSN, PARCEL_TYPE and the polygon; its PIN column is empty on every row, and there is no owner, situs, mailing, value or sale column. Owner names are not published on this layer, so owner_name is recorded as not published. WHY THIS LAYER AND NOT METRO'S: Louisville Metro's New_AllParcels FeatureServer (services1.arcgis.com/79kfd2K6fskCAkyg, 289,963 rows) adds an Address and a property class, but its last edit is 2017-01-10 and its backing item (titled 'Commercial Parcels') was last modified in 2017, so it is a nine-year-old snapshot; LOJIC's layer is the consortium's own open-data parcel layer. The LojicData folder on the same server needs a token. No terms are published on the service. Verified 2026-10-09 by a count, field list and fill counts.

Jefferson County's Jefferson County KY Parcels layer exposes a parcel identifier (Parcel ID). Use it for PIN-keyed record pulls (owner-name search lives on a separate assessor system). 1 of 3 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 2026-10-09.
/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 Jefferson County actually publishes, not what you might expect from a national standard (there isn't one).

gis.lojic.org serves Jefferson County, Kentucky 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 Jefferson County's MapServer layer on 2026-10-09. 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.
Jefferson County's layer is hosted by the county on gis.lojic.org. Public ArcGIS endpoints rarely rate-limit individual reads, but gis.lojic.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.
