Who uses the Strafford County parcel map
The same map serves very different jobs around Durham.
- Builders bidding a house on a lot in Lee start with the parcel ID and legal description, since permit paperwork usually asks for both.

What the map covers, from Dover to the back roads
Dover is the county seat, and other towns on the map include Rochester, Somersworth, Barrington, and Durham. Smaller places such as Milton and Milton Mills show up as clusters of lots along the roads. Organized in 1771, and named for William Wentworth, 2nd Earl of Strafford, Strafford County has a long paper trail, and early deeds may cite landmarks that no longer exist. Census Bureau estimates show 133,243 residents in 2023 and around 367 square miles of land in the county. Around Durham and Lee nearly every click lands on a platted lot, so the few remaining open parcels are easy to pick out. Water features such as the Salmon Falls River shape where lots fall and where floodplain sits.
Work and land use in Strafford County
Census business counts for 2022 list 2,765 establishments in Strafford County; retail trade tops the list, with construction and health care and social assistance close behind. What stands out is textile mills, electrical equipment manufacturing, and computer and electronic product manufacturing: those sectors make up a much larger slice of local businesses than they do nationally. Industrial employers often anchor demand for nearby housing lots and small acreage. Keep that in mind when you compare parcels in Strafford County: who works here shapes what land sells.
How accurate are Strafford County, NH property lines?
Zoom in far enough on a lot in Durham and you may notice lines crossing driveways or splitting sheds, a normal quirk of tax mapping. Land in New Hampshire is mostly described by metes and bounds: bearings, distances and calls to monuments or neighbors. That's why rural parcels in Strafford County rarely look square. Corner pins, a recorded plat and a New Hampshire licensed surveyor beat any line on a screen.
Vacant land and acreage on the Strafford County GIS map
To use the Strafford County GIS map for a vacant land search:
- Pan the Strafford County map with imagery turned on and flag any tract that looks empty.
- For the open ground around Dover, copy the owner, acreage and mailing address into a simple spreadsheet.
- Measure the road frontage on the map; a sliver of frontage on a road outside Dover may not be enough for a driveway permit.
- Pull up three or four similar parcels near Dover and compare their land values.
- Ask the local offices serving Farmington about building permits and septic rules before you buy.
For a tract near Dover with no road frontage, see how to tell if land is landlocked.
