Public ArcGIS MapServer endpoint for Orleans Parish parcel data. URL, supported fields, and a working sample query, copy it, or open it directly in the UrbanKit parcel lookup tool.
This page is the endpoint reference. If you came here to find a specific property, the Orleans Parish parcel search runs this same layer in your browser, no account and no API key.

We only call a field restricted when there is a stated reason we can cite. Everything else here is a fact about the services we index, not a claim about the law.

| Land use | Answered | Documented in a field list on an endpoint we index. Not every row is populated. |
| Zoning | Not published | No endpoint we index for this county documents this field, so a query cannot ask for it. That is a fact about the services we index, not a legal restriction, and not a statement that the county holds no such record. Where to request it. |

MARKED UNREACHABLE 2026-08-29. Layer 15 metadata answers and lists PARCELID, OWNERNME1, SITEADDRESS, PSTLADDRESS, but ANY query that names those columns in outFields returns ArcGIS 400 "Failed to execute query" in ~250 ms (measured 2026-08-29: PARCELID IS NOT NULL, 1=1, OBJECTID=1 and a 30 m spatial query all fail with specific outFields). outFields=* succeeds and takes 27-44 s; even outFields=OBJECTID took 27.5 s. The enrich pipeline requests specific columns, so every paid lookup here fails and refunds; the liveness probe sends the declared sampleQuery and fails the same way, which is why this parish has never once probed ok (463 consecutive failures). Layers 0-14 of the same service are zoning, overlays and address points, not parcels, and ArcGIS Hub lists no city-owned parcel feature service. County-side defect; nothing to re-point to. Liveness keeps watching. Prior notes: 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 checked 2026-08-29; currently unreachable.
/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 2026-08-29 and it was unreachable on that check. 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.
