A garage in the Mount Washington Valley often sits cold, empty and unwatched for months at a stretch. Decide early whether it will be heated or left cold, because anything holding water (a hose bib, a slop sink, a bathroom) will freeze and split in an unheated Carroll County building.
This page covers what it takes to build one here: the snow load, which is the heaviest of any town we work in, deep frost and a late thaw that squeeze the excavation window, and how to run a project from Boston or Connecticut with weekly photo updates and written change orders.
We introduce you to three builders from our network who quote the same scope, and the introduction costs you nothing. Every builder clears a ten-step check on insurance, references, work history and communication first. Turnkey garage shell pricing in this region runs $126 to $155 a square foot, higher inside that band where excavation is heavy.
How do you run a Conway garage build from away?
Three practical realities shape every building project in this valley.
The season is the shortest we work in. Deep frost, a late thaw, and early snow leave a genuinely narrow excavation window. Foundation crews commit it early, and calling in spring for a spring dig is late. Plan the winter before.
A garage suits that window better than most projects. Once the foundation is in and the building is framed, roofed, sided and has doors, the weather stops mattering. So the sequence is: dig as soon as the ground opens, get closed in through the summer, finish the inside whenever.
Managing it from away takes structure. If you are running this from Boston or Connecticut, put weekly written updates with photos in the agreement, and require written change orders before any extra work proceeds. That is not distrust, it is what keeps a remote project honest and it is worth more than anything else you can negotiate.
Two other points matter in Conway. The Saco River flood plain runs through the area and affects riverside property, so confirm flood status before choosing a location.
New Hampshire has no sales tax, which can make a real difference on a garage materials package compared with Maine. The amount depends on where the materials are bought and delivered.
Ask your contractor directly.
Take permit and site questions to the Town of Conway building department.
One legal point, because people cross the border and assume: New Hampshire's rules are not Maine's. Maine's written-contract threshold and its cap on deposits are Maine statutes and they do not apply to a project in Conway. That does not make a written contract optional. It makes it more important, because you are relying on the document rather than on a statute. Get the full scope, the payment schedule, the change order process and the completion terms in writing before any money moves.

How much does a garage cost in Conway, NH?
Turnkey garage pricing across the region runs about $126 to $155 per square foot for the building itself, before any interior finish. Mountain construction falls near the top because snow requires heavier structure and the building season is short.
| Garage | Size | Range | Timeline |
|---|---|---|---|
| 1-bay detached | 14x24 (336 sq ft) | $44,000 – $52,000 | 4 – 6 weeks |
| 2-bay detached, unheated | 24x24 (576 sq ft) | $75,000 – $90,000 | 6 – 10 weeks |
| 2-bay insulated with minimal heat | 24x24 (576 sq ft) | $81,000 – $99,000 | 8 – 12 weeks |
| 2-bay oversized for sleds, trailer or truck | 24x28 (672 sq ft) | $88,000 – $104,000 | 7 – 11 weeks |
Foundation work usually accounts for about one-quarter of the total. A slab commonly costs $15,000 to $20,000.
A full frost wall runs $20,000 to $25,000, with deep mountain frost pushing Conway toward the top of both ranges.
Don't chase savings on the engineered roof structure or the door. Both must handle snow and weather, and this climate is hard on them.
Build on the four-foot grid. Sheets are 4x8, while framing lumber comes in four-foot lengths.
Dimensions of 24 and 28 feet use material cleanly. At 22 or 26 feet, you buy the same material and waste part of it.
Less cutting also saves site time during the short season.

What happens to a garage that sits cold and empty?
A garage at a property visited eight weekends a year behaves differently from one attached to a full-time home in Mount Washington Valley.
Decide up front whether it is heated or cold, because half the details follow from that. An unheated building in this valley will reach outdoor temperature and stay there for months. That is completely fine, as long as everything in it and everything serving it is chosen with that in mind.
Anything with water in it is the risk. If the plan includes a slop sink, a hose bib, or a bathroom, an unheated garage in Carroll County will freeze and split it. Either the building gets heat and stays above freezing all winter whether you are there or not, or the plumbing gets designed to be drained and left dry. Half measures are how people come back in April to a flooded slab.
A little heat is not the same as no heat. Keeping a building just above freezing is much cheaper than keeping it comfortable, and it is what protects plumbing and equipment. If the building will hold anything that matters, price a minimal heating setup and the electrical to run it, rather than deciding later.
Condensation on a cold slab is real. Bring a warm, wet vehicle into a cold building and moisture lands on the concrete and on everything metal. Batteries, tools and stored gear pay for that over time. Ventilation and getting the vehicle dry matter more than most people expect.
Then there is what actually gets stored here. Sleds, a plow truck, bikes, kayaks, ski gear, a generator, firewood. That mix wants wall height, clear floor, and a door tall enough for a truck with a rack or a trailer with a rise. Sit down and list what goes in it before anyone draws a footprint.
And plan for the building being empty when weather happens. Snow retention over the entry door, a roof orientation that does not dump on the walkway, and a way to get to the building when the driveway has not been touched in three weeks are all decisions made on paper, not solved in February from two states away.
This applies to second-home owners tired of digging vehicles out of the driveway. It also applies to year-round residents in Conway village and Center Conway who need storage or workspace, along with owners near the Saco converting seasonal property for greater use.
Decide first whether the garage will be heated or cold. The work may include excavation and foundation construction, followed by framing.
It may also cover an engineered roof for local snow, siding and doors. Openers, an entry door and electrical work come next, with any minimal heat needed to protect the contents.
Detached garages here get gravel to the door, just as they do in Maine. With this much snow, plus repeated freezing and thawing, a rigid poured apron is a bad bet.
It's a maintenance problem waiting to happen.
Dig as soon as the ground permits. That happens later here than anywhere else we serve.
Close in the building before the snow, then finish the interior during winter.
Book the work the winter before. In this seasonal market, availability matters more than price.
The hard part is the combination of a mountain winter and part-time occupancy. At a full-time home, somebody notices trouble quickly.
Here, a garage may sit alone through the worst months. Build accordingly.
On credentials, and this matters on both sides of the border: New Hampshire does not license general contractors at the state level, and neither does Maine. Building permits come from the town, and a contractor should be properly registered as a business. What actually tells you something is current insurance, references, financial stability and reputation, and that is what our ten-step process verifies before we introduce anyone.
What do Conway homeowners want to know first?
Should a vacation-home garage in Conway be heated?
It depends what is in it. Anything with water in it needs either real freeze protection or a design that can be drained. Keeping a building just above freezing is far cheaper than keeping it comfortable.
Why does my cold garage get damp?
Condensation. Warm wet vehicles bring moisture into a cold building and it settles on the slab and on metal. Ventilation helps more than heat alone.
Do general contractors need a license in Conway, New Hampshire?
New Hampshire does not license general contractors at the state level. Permits come from the town. Verify insurance and references instead.
Do Maine's contract rules apply to a New Hampshire project?
No. Maine's written-contract threshold and deposit cap are Maine statutes. Get everything in writing anyway, because in New Hampshire the document is what you are relying on.
