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.

Beyond the parcel record, Orleans Parish has a free New Orleans property report: code violations and building permits for an address, read straight from the city's open data.
Free New Orleans property report: code violations + building permitshttps://gis.nola.gov/arcgis/rest/services/apps/property3/MapServer/15Field by field, whether any endpoint we index for Orleans Parish answers it, and the evidence for each. 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.

LIVE 2026-10-03 for lookup by location in clients that complete the TLS chain (see TLS below); no attribute search. Layer 15 refuses any query that NAMES its outFields except an exact PARCELID equality: measured 2026-10-03 on the paid shapes (point + 30 m buffer; 800 m envelope with geometry) and on a scan (OBJECTID>0, resultRecordCount=1), every named column list answers HTTP 200 carrying ArcGIS error 400 "Failed to execute query." in about 0.2 s, while the identical request with outFields=* answers 40 features in 0.28 s and 501 features (957 KB) in 0.65 s. UrbanKit sends outFields=* to this layer (api/_lib/arcgis-quirks.ts, WILDCARD_OUT_FIELDS) and keeps only the role columns. Any predicate that scans the table (1=1, OBJECTID>0, PARCELID IS NOT NULL, an owner LIKE) runs past 40 s even for a single row, so no where-clause search is offered (attributeSearch: unsupported) and owner-name lookup is not available here; the owner columns (OWNERNME1, OWNERNME2) and the mailing address (PSTLADDRESS, PSTLCITY, PSTLSTATE, PSTLZIP5) are returned on every spatial hit (a UrbanKit row keeps PSTLADDRESS, the street line). IDS: PARID is the assessor's per-unit parcel id (e.g. 622-SALEXANDERST) and is listed first so rows key by unit; PARCELID is the GeoPIN, a lot id shared by every condo unit on the lot (a 30 m buffer in the CBD: 40 units, 3 lots, 39 owners), so keying on it would collapse a notice list to one row per lot; TAXBILLID is the tax bill number. Exact PARCELID equality answers in 0.2 s and is the sample query, which is also the predicate the liveness probe falls back to when its first shape (1=1) times out. CORS reflects the request origin. TLS: the server sends an INCOMPLETE certificate chain (leaf without its Sectigo intermediate). Clients that fetch the missing intermediate themselves (curl on Windows, Chromium and Safari through the OS store) connect; Node's fetch fails the handshake with UNABLE_TO_VERIFY_LEAF_SIGNATURE (measured 2026-10-04). UrbanKit's billed bulk-enrichment and radius paths run on Vercel's Edge runtime, which cannot be given a certificate authority and whose handling of an incomplete chain is undocumented and not yet measured, so assume they cannot serve this parish until a keyed test on the deployed function shows otherwise; today an Orleans row ends county-unavailable and is refunded, unchanged from before. The liveness probe pins the intermediate, so its ok reflects the layer, not the paid paths. An agent that fetches this URL from Node must trust the Sectigo intermediate or the request fails before any query runs. Tracked in GitHub issue #906. HISTORY: marked unreachable 2026-08-29 after 463 consecutive failed probes whose predicate (PARCELID IS NOT NULL) is a table scan; the layer was answering spatial queries the whole time. Ownership data looked dated during the 2026-08 checks; the 2026-10-03 rows carry current-looking owner names.

Orleans Parish's Property Information [Parcels] layer exposes parcel identifiers (Parcel ID (PARID, per unit), GeoPIN (lot id, shared by condo units)). 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 2026-10-03.
/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 2026-10-03. 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.
