Orleans Parish's public parcel layer still serves metadata, but its attribute-query operation is currently failing on the county's ArcGIS server. Owner and address searches are unavailable while the county repairs the service; automatic probes continue to check for recovery. New Orleans uses Square/Lot identifiers for legal parcels. The city also publishes a weekly situs-and-geometry dataset on data.nola.gov, but it does not include owner names. An older 2018 parcel snapshot was not substituted because its ownership data is dated and the service was unstable during verification. LIVENESS 2026-08-04: the layer's metadata still loads, but EVERY query against it times out, including a bare returnCountOnly count. 161 consecutive failed checks and last_ok_at has never been set. This is a county-side outage, not a schema drift; there is nothing to fix on our side and the endpoint stays honestly degraded until New Orleans repairs it.

Orleans Parish's Property Information [Parcels] layer exposes a parcel identifier (Parcel ID). Use it for PIN-keyed record pulls (owner-name search lives on a separate assessor system). 3 of 15 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 2026-06-27.
/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 Orleans Parish actually publishes, not what you might expect from a national standard (there isn't one).

gis.nola.gov serves Orleans Parish, Louisiana 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 Orleans Parish's MapServer layer on 2026-06-27. 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.
Orleans Parish's layer is hosted by the county on gis.nola.gov. Public ArcGIS endpoints rarely rate-limit individual reads, but gis.nola.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.
