South Carolina has 46 counties, each with an elected County Assessor responsible for parcel assessment and recordkeeping. The SC Department of Revenue provides oversight of the assessment system but does not operate a statewide parcel REST service. The SC Department of Natural Resources (SCDNR) maintains some statewide GIS layers, but cadastral parcel data is county-by-county. A large share of SC counties, particularly smaller ones, contract with Schneider Geospatial's qPublic platform for their public parcel viewer. qPublic delivers a browser-based map and property search but does not expose a standard queryable ArcGIS REST endpoint behind it. Charleston and Greenville self-hosted ArcGIS Server and published MapServer endpoints with field-level query access; Greenville's parcel map services were taken down in August 2026, and Charleston County told us it does not authorize this use of our data, so the atlas retired its endpoint on 2026-10-21.
South Carolina has no statewide parcel aggregation program comparable to Vermont's VCGI or Wisconsin's WLIP. The SC Office of the Adjutant General's GIS office and SCDNR maintain statewide layers for boundaries, imagery, and natural resources, but parcel cadastral data is not centrally coordinated. County GIS offices affiliate through the SC Geographic Information Council (SCGIC), which promotes standards but has no enforcement authority over assessor data publication. Charleston County self-hosts ArcGIS infrastructure but told us it does not authorize this use of our data, so the atlas lists no endpoint for it; Greenville County self-hosted one until August 2026 and now publishes no parcel REST service. Most of SC's remaining 44 counties route through the qPublic.schneidercorp.com or Beacon portal, both Schneider Geospatial products. These portals are purpose-built for county property searches: they show maps, assessment data, and deed history, but they do not expose a documented REST API for programmatic query.
A majority of South Carolina's 46 counties use Schneider Geospatial's qPublic or Beacon platform as their public-facing assessor portal. These portals work well for manual lookups: you can search by owner name, address, or parcel ID, view a map, and see assessment history. They do not expose a standard ArcGIS REST endpoint that accepts query parameters. Developers building parcel lookup tools for SC's smaller counties have no REST path. They must scrape the portal (fragile) or use a commercial data provider. Charleston County was the primary exception, with a self-hosted ArcGIS server, until it told us it does not authorize this use of our data and the atlas retired its endpoint on 2026-10-21; Greenville County was the other until its parcel map services came down in August 2026.
South Carolina parcels are identified by a PIN (Parcel Identification Number) assigned by the county assessor. There is no statewide PIN standard. Greenville County uses a format like 0071.05-01-004.03. Charleston County uses a PID and a separate GPIN (GIS Parcel ID). Smaller counties using qPublic use their own internal account number formats. The SC DOR's property tax forms reference a county-assigned TMS number (Tax Map System) in many jurisdictions. This is the same as or closely related to the PIN but the field label varies by county.
Largest county in the SC Upstate (~530,000 residents, including Greenville City and Mauldin). No public parcel REST endpoint as of 2026-10-18, and the county has retired it rather than let it lapse. The Tax Parcel layer (index 52 in the GreenvilleJS/Map_Layers_JS MapServer at gcgis.org, with PIN, OWNAM1, OWNAM2, STREET, DEEDDATE, LANDUSE and SUBDIV) went down in August 2026, the GreenvilleJS folder has since been deleted, and the gcgis.org services root now lists no map services at all. The county sells its tax parcels with ownership information as countywide vector data on a USB drive under a release agreement instead, and the rebuilt county viewer runs on a private web API that is not a queryable ArcGIS REST service. Owner lookups go through the county's Real Property Search in a browser.
Largest county by land area on SC's coast (~430,000 residents, including Charleston City, North Charleston, and Mount Pleasant). Not indexed: the county told us it does not authorize this use of our data, so the atlas lists no endpoint for Charleston. Ask the county at WebMasterGIS@charlestoncounty.org if you would like that to change.
Greenville: no REST query path as of 2026-10-03 (the county deleted its GreenvilleJS map services); use the county's Real Property Search in a browser. For qPublic counties (most of SC): qpublic.schneidercorp.com/Application.aspx?App=<CountyNameSC>&Layer=Parcels&PageType=Search, browser only, no REST.

2 South Carolina counties are indexed in the UrbanKit atlas with verified public REST endpoints: Georgetown and York. They index by parcel ID and address; owner lookups go through the county assessor or appraiser.
Georgetown publishes parcels at https://gis1.georgetowncountysc.org/portal/rest/services/GCGIS_OpenData/FeatureServer/2, a FeatureServer (layer 2). It indexes by TMS (tax map parcel number), Plat Reference, and Zoning District.
South Carolina's indexed counties (Georgetown and York) publish ArcGIS FeatureServer layers, the newer ArcGIS Online-hosted format. FeatureServer supports the /query operation for owner, parcel-ID, and address lookups.
