Trying to size up a property near Franklin? A Concord GIS map search is the quickest way to find out, without paying for a report. Covered here for Concord: where that map lives, how to search it, and the limits worth knowing.
Where the Concord GIS map lives
On ground around Loudon, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Where the parcel data lives
Go first to the NHDOT Parcel Mosaic Viewer; it maps every tax parcel around Loudon and Warner. When a rural tract has no street number, pan along the nearest road until the lines appear, then click inside the one you want, whether the land is near Henniker or elsewhere in the county. If the land is near Franklin, write down the parcel ID while you have it open; each clerk in the county asks for it first.
Concord, NH: the basics
Concord lies within Merrimack County, New Hampshire, so its parcels are on the county's map. As the county seat, Concord hosts the courthouse, which puts the county Registry of Deeds close by. If you're looking near Loudon, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Lots just outside the city limits out by Pittsfield generally follows county rules, not municipal ones.
Saving what you find

A word on accuracy
Acreage on the record is an estimate; just a licensed surveyor can set the real boundary on land around Franklin. On ground around Pittsfield, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Who handles what
Deeds, mortgages and recorded plats for land near Warner are with the county Registry of Deeds, often with an online index. Zoning, permits and septic questions near Loudon are for the local planning and health departments, depending on whether the land is inside town limits.
Where the recorded documents are
The map is an index, not the title: recorded deeds, plats and easements covering ground around Hooksett are filed with the county Registry of Deeds. Inherited tracts near Henniker can go back through a long string of deeds, so a title company is worth hiring before a purchase.
