Public ArcGIS MapServer endpoint for Greenville County parcel data. URL, supported fields, and a working sample query, copy it, or open it directly in the UrbanKit parcel lookup tool.
This page is the endpoint reference. If you came here to find a specific property, the Greenville County parcel search runs this same layer in your browser, no account and no API key.

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.

| APN | Answered | Documented in a field list on an endpoint we index. Not every row is populated. |
| Owner name | Answered | Documented in a field list on an endpoint we index. Not every row is populated. |
| 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. Where to request it. |

MARKED UNREACHABLE 2026-08-29 after 25 days down (297 consecutive liveness failures since 2026-08-04). The registered service answers verbatim "Service GreenvilleJS/Map_Layers_JS/MapServer not started"; the county's own iMAP service (imap/iMAP/MapServer) is also not started; the GreenvilleJS and imap folders list no services; the one visible service (GCGIA/Greenville_Base, 61 layers) has no parcel layer; ArcGIS Hub lists no county-owned parcel feature service. The county has taken its map services down and nothing replaces them yet. Liveness keeps probing; flip back to live when it recovers. Owner search remains available at the county's non-GIS Real Property Search. Prior notes: Greenville County (pop. 530,000; seat: Greenville) Tax Parcel layer is within the Map_Layers_JS composite MapServer at layer index 52. 20 fields confirmed: PIN, OWNAM1/2, STREET, CITY, STATE, ZIP5, NAMECO, POWNNM, DEEDDATE, CUBOOK, CUPAGE, PLTBK1, PPAGE1, DIST, MKTAREA, JURIS, LANDUSE, DESCR, SUBDIV. Verified 2026-05-15: SMITH returns Greenville SC addresses (e.g., '124 MCDANIEL GREENE', '218 BUTLER AVE'). The same MapServer contains 95+ other layers (zoning, census, drainage, etc.). Layer 52 is specifically Tax Parcel. The GCGIS GreenvilleJS MapServer is the public-facing viewer service.

Greenville County's Tax Parcel layer exposes a parcel identifier (Parcel Identification Number), owner names (Owner Name 1), and address fields (Street Address). Use it for owner-name lookups and address-based parcel searches. 3 of 14 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 checked 2026-08-29; currently unreachable.
/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 Greenville County actually publishes, not what you might expect from a national standard (there isn't one).
For background, see What is an APN?
www.gcgis.org serves Greenville County, South Carolina 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 Greenville County's MapServer layer on 2026-08-29 and it was unreachable on that check. 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.
Greenville County's layer is hosted by the county on www.gcgis.org. Public ArcGIS endpoints rarely rate-limit individual reads, but www.gcgis.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.
