Fayette County (Lexington, pop. 322,000; consolidated city-county) Tax Parcels FeatureServer hosted on ArcGIS Online (LFUCG org). Fayette County is a merged urban county government — the Lexington-Fayette Urban County Government (LFUCG). Fields confirmed: PAN (numeric parcel account number), PARCEL_SUB, PARCEL_BLOCK, PARCEL_LOT, LRM_GEOM_DOC, RecordDate, LRM_GEOM_DOC_AREA/UNITS, PARCEL_TYPE, PARCEL_POLY_NAME, Owner1/2/3, Mailing_Address. Note: PARCEL_POLY_NAME may be null; PAN is the numeric parcel identifier. Mailing_Address is a single concatenated field. Verified 2026-05-15: Owner1 SMITH returns Lexington-area addresses (e.g., '3875 GEIST RD STE E469', '4951 E JOHN JOHN CT'). A separate Parcels FeatureServer exists at the same org but has no owner fields — Tax_Parcels is the correct service. Note: distinct from Jefferson County KY (Louisville, FIPS 21111) already in atlas.

/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.
