Gwinnett County (pop. ~975,000; Lawrenceville seat; Atlanta metro northeast, Georgia's second-most-populous county) publishes a Property_and_Tax FeatureServer. IMPORTANT: owner data lives on LAYER 3 (the 'Tax Master Table', a non-spatial Table with 35 fields including OWNER1, OWNER2, PIN, LOCADDR, LOCCITY, LOCZIP), NOT on layer 0, which is the parcel geometry layer carrying PIN but no owner name. Query layer 3 for owner-name search; join to layer 0 on PIN if geometry is needed. Verified 2026-06-20: layer 3 holds 314,998 records; UPPER(OWNER1) LIKE '%SMITH%' returns real owners with Duluth/Norcross addresses and ZIPs (e.g. '4078 STILLWATER DR, DULUTH 30096'). Because layer 3 is a Table, query results return no geometry. Cities within the county include Lawrenceville, Duluth, Norcross, Snellville, Suwanee, Lilburn, Buford, Sugar Hill, Grayson, Loganville, Berkeley Lake, Dacula, Auburn, Braselton, Peachtree Corners. For authoritative assessment/appeal records use the Gwinnett County Tax Assessor's office.

Gwinnett County's Tax Master Table layer exposes a parcel identifier (Parcel Identification Number), owner names (Owner Name 1, Owner Name 2), and address fields (Property (Location) Address). Use it for owner-name lookups and address-based parcel searches. 4 of 6 listed fields accept queries; the rest are returned on read but not indexed for search. Served as an ArcGIS FeatureServer layer, so edits and applyEdits operations are technically exposed (read access only is published here); last verified 2026-06-20.

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 Gwinnett County actually publishes, not what you might expect from a national standard (there isn't one).

services3.arcgis.com serves Gwinnett County, Georgia 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 Gwinnett County's FeatureServer layer on 2026-06-20. 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.
Gwinnett County's layer is hosted on Esri ArcGIS Online. Public ArcGIS endpoints rarely rate-limit individual reads, but services3.arcgis.com 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.
