Prefab homes in Montana: modular & ADU builders
Modular, ADU, and factory-built companies serving Montana. Compare listings, then contact builders directly.
In this market
Montana's wide-open sites favor modular home builders willing to travel long distances for set and finish. Prefably lists 51 factory-built companies advertising Montana service, from Missoula and Bozeman to Billings, Kalispell, and rural counties.
Freight, crane access, and winter weather windows often dominate planning. Confirm snow loads, WUI detailing where required, and whether crews serve your county year-round. Ask whether the package is modular to local code or HUD-code manufactured.
Every row on this page links to a Prefably company profile. Listings start as Unclaimed public records drawn from business data; builders can claim them free to update contact info and specialties. Prefer profiles with published ratings and a working website, then request a written factory-vs-site scope before you deposit.

Context
More about prefab in Montana
Ground truth for Montana buyers: wildland-urban interface counties commonly require Class A roofing, ignition-resistant siding, and ember-resistant venting. Cold-climate envelopes often exceed R-30 walls with triple-pane glazing. Long-haul freight and seasonal road limits can dwarf finish upgrades, get barge-or-truck, crane, and winter-set line items in writing. A catalog home designed for a milder climate is not automatically Montana-ready.
Open profiles for ratings and websites when available, then shortlist three operators with documented Montana delivery. Unclaimed listings stay visible until builders claim them free.
Reach out directly. Prefably does not sell leads. Use our cost and financing guides when you budget freight and foundation work.
FAQs
Prefab homes in Montana
How many prefab and modular builders does Prefably list in Montana?
As of 2026, Prefably lists 29 factory-built home companies associated with Montana in this directory (claimed and unclaimed). Counts change as companies claim profiles or we add listings — use the cards on this page for the current shortlist, then contact builders directly.
Are prefab homes practical in Montana winters?
Yes, and often warmer than site-built thanks to factory-controlled insulation. Most Montana-ready packages exceed R-30 walls and use triple-pane glazing.
How does Montana wildfire code affect prefab?
Wildland-urban interface counties commonly require Class A roofing, ignition-resistant siding, and ember-resistant venting. Ask for a WUI package, not a milder-climate catalog.
Does freight dominate Montana prefab cost?
Often yes. Long-haul truck or seasonal access can dwarf finish upgrades. Get freight, crane, and winter-set line items in writing.
Modular vs manufactured in Montana?
Modular on a permanent foundation is typically real-property lending. HUD-code manufactured homes use a different label and often a different loan product.
How do I find a local modular builder that delivers to my county in Montana?
Use this directory to shortlist companies that advertise Montana service, then ask each one to confirm haul routes, crane access, and set crews for your specific county, not just the nearest metro. Rural lots often need a site visit before a quote is real. Open Prefably profiles for ratings and websites, compare at least three written factory-vs-site scopes, and treat “statewide” marketing as a starting claim, not proof. Pair this page with our prefab-vs-modular and cost guides before you deposit.
