Charleston County (pop. 430,000; includes Charleston, North Charleston, Mount Pleasant) Parcel_Search MapServer layer 4. This layer is a spatial join of parcel geometry (FEATURES.SDE.P_POLY_PARCEL) with CAMA assessor data (FEATURES.SDE.CAMA), so field names are fully qualified with schema prefix. 20 fields confirmed: PID, GPIN, ACRES_CAL, OWNER1/2, TAX_DISTRICT, CLASS_CODE, MAIL_ST_NO/ST_NAME/ST_TYPE, MAIL_2ND_ADDR/ADDT, MAIL_CITY/STATE/ZIP/COUNTRY, LEGAL_DESCR, SUBDIVISION. IMPORTANT: field names in WHERE clause must be double-quoted due to dot notation (e.g., UPPER("FEATURES.SDE.CAMA.OWNER1") LIKE ...). Verified 2026-05-15: SMITH returns Edisto Island and Spring City area addresses.

/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.
