No public parcel REST endpoint we can serve for Rockingham County.
New Hampshire's statewide parcel layer is public but carries no owner names; owner records are kept by each town's assessor. Search the town's assessor viewer, or request Rockingham County and we'll tell you if that changes.

NH GRANIT's statewide parcel mosaic is public with no login at nhgeodata.unh.edu/hosting/rest/services/Hosted/CAD_ParcelMosaic/FeatureServer/1 (checked 2026-10-17), the same layer Hillsborough County's notes describe, but it has no owner field: parcel ids, town, street address and land-use codes only. An older GRANIT MapServer (nhgeodata.unh.edu/nhgeodata/rest/services/CAD/ParcelMosiac/MapServer) answered HTTP 499 without a token when this county was first researched. Rockingham County covers Portsmouth, Salem, Derry, Londonderry, and the southern tier of Manchester suburbs. Owner records sit with each town's assessor on separate vendor sites: Vision Government Solutions hosts assessor data for Salem, Derry, and several others, and AxisGIS serves Rye, Deerfield, and others; none expose a standard queryable ArcGIS FeatureServer. Regrid covers NH at commercial tier. The Rockingham County Registry of Deeds (ecourt.rockinghamregistry.com) is publicly searchable for recorded instruments but does not expose a REST parcel layer.

Rockingham County does not yet have a verified public REST endpoint in our atlas. The sections below cover patterns common to most county parcel APIs.
/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 Rockingham County actually publishes, not what you might expect from a national standard (there isn't one).
For background, see What is an APN?
