Cobb County (Marietta seat, pop. 766,000; Atlanta metro northwest) maintains a Tax Assessor parcel layer at gis.cobbcounty.org that refreshes nightly from CAMA data -- the service name 'taxassessorsdaily' reflects this cadence. 36+ confirmed fields: PIN, PARID, PARCEL_TYPE, OWNER_NAM1/2 (owner names), SITUS_ADDR (site address), OWNER_ADDR/CITY/STAT/ZIP (owner mailing address), TAXDIST, ACRES, FMV_LAND (fair-market land value), FMV_BLDG, FMV_TOTAL, ASV_LAND (assessed land), ASV_BLDG, ASV_TOTAL, CLASS (property class), NBHOOD_NUM (neighborhood code). Verified 2026-05-15: SMITH returns results from Acworth, Marietta, Powder Springs, and Kennesaw. Cobb County borders Atlanta only in limited segments and has no parcel-boundary overlap with the city. The county's GIS Hub at geo-cobbcountyga.hub.arcgis.com and the Property Search portal at gis.cobbcounty.org/PropertySearch.html both provide web-interface access. The Cobb County Board of Tax Assessors (cobbassessor.org) is the authoritative record for appeals, exemptions, and recent reassessment values.

Cobb County's CobbParcels layer exposes a parcel identifier (Parcel Identification Number), owner names (Owner Name 1), and address fields (Site Address). Use it for owner-name lookups and address-based parcel searches. 4 of 9 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 verified 2026-05-15.

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

gis.cobbcounty.gov serves Cobb 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 Cobb County's MapServer layer on 2026-05-15. 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.
Cobb County's layer is hosted by the county on gis.cobbcounty.gov. Public ArcGIS endpoints rarely rate-limit individual reads, but gis.cobbcounty.gov 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.
