Conway anchors the Mount Washington Valley, and North Conway is a village inside it rather than a town of its own. Langone Site Services builds turn-key ADUs there and handles excavation, site work and septic. The catalog runs from $147,000 to $388,000, and a New Hampshire septic system is priced from the lot. Call (978) 987-0089.
The state floor is one ADU by right with no living-area maximum below 750 sq ft. Work near the Saco still falls under shoreland rules, and the district sets front, side and rear. We read the ordinance against your lot.
Conway is the Carroll County town at the mouth of the Mount Washington Valley, and North Conway is a village in Conway rather than a separate town. The Saco River runs through it and Cranmore stands above the village. RSA 674:71-73, as amended by HB 577, requires one ADU by right where single-family homes are allowed, and the town must permit a detached unit.
A North Conway village lot and a hillside parcel outside it are not the same setback. We'll read the Conway district against your lot.

Price a Conway ADUValley ground runs from river-plain sand to ledge on the hillsides, so a septic design and a driveway here both start with what the test pit shows. Frost and plowing decide how a drive gets built as much as the grade does.
ExcavationA Conway system has to be sized for four-season use, and the valley's sand, ledge and water table decide the design. That price comes out of the test pit, not a table.
Septic installationConway site work answers to frost and plow season, from North Conway village out to the hill lots above the Saco.
Site workEvery town we cover is listed on the service area page.
We will read the ordinance against your parcel, look at what the ground will take for septic and access, and come back to you with a figure rather than a range.
