About the official source
This is a statewide map, not a county site. NHDOT Parcel Mosaic Viewer covers parcels across New Hampshire, and Grafton County is one part of it. Statewide parcel layers are usually stitched together from county files, so the newest splits or sales may show up on the county's own records first. When we tested the link in October 2026 it opened with no login and no fee.
How to use the Grafton County viewer
- Open NHDOT Parcel Mosaic Viewer in a new tab and zoom to Grafton County.
- Type a street address into the search box, or click directly on a parcel.
- Review the parcel attributes; field names vary by state.
- Confirm anything important with the county assessor, since the statewide layer is a compiled copy.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.

Before you rely on the lines
The lines you see online are approximate. They're good for finding a lot and its parcel number, but a legal boundary question needs the recorded plat or a surveyor.
