Morris County (pop. 510,000; northern NJ exurbs) has no county-direct REST parcel layer that exposes owner data. The local morrisgisapps.co.morris.nj.us MapServer exists but returns only PAMS_PIN and shape geometry -- insufficient for owner or address lookup. The NJOGIS statewide cadastral layer at maps.nj.gov (Framework/Cadastral/MapServer/0) is the practical choice; filter with COUNTY='MORRIS'. Fields include OWNER_NAME, PAMS_PIN, PROP_LOC, MUN_NAME, PROP_CLASS, LAND_VAL, IMPRVT_VAL, NET_VALUE, SALE_PRICE, YR_CONSTR, and CALC_ACRE. Morris County's 39 municipalities include Morristown, Parsippany-Troy Hills, Dover, Rockaway Township, Randolph, and several with significant commercial and industrial parcels along I-80 and Route 10. The MOD-IV quarterly update cycle applies; data reflects the prior quarter's county submission. NJ Daniel's Law address-redaction applies. For recorded instruments, the Morris County Clerk document portal is at morriscountyclerk.org.

Morris County's Parcels (NJ Statewide Cadastral) layer exposes a parcel identifier (PAMS Property Identification Number), owner names (Owner Name), and address fields (Property Location / Address). Use it for owner-name lookups and address-based parcel searches. 5 of 10 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 Morris County actually publishes, not what you might expect from a national standard (there isn't one).

maps.nj.gov serves Morris County, New Jersey 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 Morris 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.
Morris County's layer is hosted by the county on maps.nj.gov. Public ArcGIS endpoints rarely rate-limit individual reads, but maps.nj.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.
