Property Lines Map NH
A property lines map for New Hampshire is the local parcel viewer. Open the county GIS map from Platbookmapper instead of relying on a statewide outline.

New Hampshire has 10 counties. Towns keep a great deal of the local record, and the county parcel viewer is still the practical map of lot lines. A state outline of those 10 counties will not show a house lot.
The line people want is the assessor's parcel polygon: the lot as the local office maps it for taxes. It shows which parcel is which. It does not mark iron pins, and it is not precise enough for a fence or a setback. Aerial photos underneath the line are clues, not monuments.
Open the New Hampshire property lines map
- Start at the Platbookmapper home page and search the county, parish, or borough.
- Or open the New Hampshire directory and pick the local viewer from the list.
- Follow the official GIS link. That leaves Platbookmapper and opens the local parcel map.
- Search the site address or the parcel number on the tax bill. Vacant land and new buildings often have no address in the file yet.
Platbookmapper only links out to those local parcel and lot-line GIS maps. It does not host the lots, and the line on the screen is not a survey.
Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey.
