No public parcel REST endpoint we can serve for Hillsborough 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 Hillsborough County and we'll tell you if that changes.

NH GRANIT publishes a statewide parcel mosaic with no login at nhgeodata.unh.edu/hosting/rest/services/Hosted/CAD_ParcelMosaic/FeatureServer/1: 617,124 parcels, CORS-enabled, 2,000 rows per page with pagination (checked 2026-10-17). It carries parcel ids, town, street address and land-use codes, but no owner field, so it cannot answer an owner lookup. 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. Owner records sit with each town's assessor: Hillsborough County municipalities (Manchester, Nashua and others) run their own parcel viewers through AxisGIS and Vision Government Solutions, which are property search pages, not queryable endpoints. Regrid covers NH commercially.

Hillsborough 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 Hillsborough County actually publishes, not what you might expect from a national standard (there isn't one).
For background, see What is an APN?
Not in our atlas yet. Hillsborough County either runs a token-gated server or a viewer-only portal. If you know a public ArcGIS REST URL for it, add it to the request form above and we'll check it.
