Bernalillo County is New Mexico's most populous county (pop. 680,000; county seat Albuquerque, which contains roughly 90% of the county population). The Public_Access_Parcel_Data_EAT MapServer on assessormap.bernco.gov (ArcGIS Server 11.1) is the Bernalillo County Assessor's enterprise assessment and tax parcel layer. Live query confirmed 256,034 parcels with full owner-name and situs-address exposure. Key fields: UPC (Unique Parcel Code, a 20-character alphanumeric ID, e.g. '102106049820341601AL'), TAXYR, OWNER, SITUSADD (full situs address, e.g. '3501 JUAN TABO NE J1'), SITUSCITY, SITUSSTATE, SITUSZIP, OWNADD, OWNADD2, OWNCITY, OWNSTATE, OWNCOUNTRY, OWNZIPCODE, OWNZIP4 (full owner mailing address), TAXDIST, LEGALDESC, ROLLTYPE, VALCLASS, PROPCLASS, LANDVALUE, AGVALUE, IMPTVALUE, TOTVALUE, TOTTXBLE, NETTAXABLE, ACREAGE. UPC format encodes township/range/section/parcel in a compound alphanumeric string. Owner-name search via UPPER() LIKE on OWNER works. The assessor also maintains a public property search UI at assessor.bernco.gov. Note: assessormap.bernco.gov is a separate subdomain from the county's PDS GIS server at pdsgismaps.bernco.gov. Both are public; only assessormap.bernco.gov has the parcel-with-owner layer. The county GIS server at pdsgismaps.bernco.gov has the canvass parcel polygons (BernCo_Public_Canvass_Update/MapServer layer 6) but that layer has only UPC + situs address, not owner name.

Bernalillo County's Parcels layer exposes a parcel identifier (Unique Parcel Code (APN)), owner names (Owner Name, Owner Mailing Address, Owner Mailing City, Owner ZIP Code), and address fields (Situs Address, Situs City). Use it for owner-name lookups and address-based parcel searches. All 7 listed fields accept queries. Served as an ArcGIS MapServer layer, which supports query operations but not write operations; last verified 2026-06-05.
/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 Bernalillo County actually publishes, not what you might expect from a national standard (there isn't one).

assessormap.bernco.gov serves Bernalillo County, New Mexico 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 Bernalillo County's MapServer layer on 2026-06-05. 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.
Bernalillo County's layer is hosted by the county on assessormap.bernco.gov. Public ArcGIS endpoints rarely rate-limit individual reads, but assessormap.bernco.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.
