Real, state-adjusted estimates for Montana — every figure here is computed with Montana's labor and material rates, 2% below the national average. A 40×60 pole-barn shell runs $35,280 – $70,560; a finished barndominium, $240,750 – $564,522.
Example estimates
These are live cost-engine outputs with Montana's regional multipliers applied — not generic averages. Adjust size, finish, and options in the calculator for your exact build.
| Building | Size | Estimated cost | Per sq ft |
|---|---|---|---|
| Pole barn | 40×60 (2,400 sq ft) | $35,280 – $70,560 | $15 – $29/sq ft |
| Pole barn | 30×40 (1,200 sq ft) | $38,959 – $85,077 | $32 – $71/sq ft |
| Metal building | 40×60 (2,400 sq ft) | $37,632 – $79,968 | $16 – $33/sq ft |
| Barndominium | 40×60 (2,400 sq ft) | $240,750 – $564,522 | $100 – $235/sq ft |
Computed from the BarnCostHub cost engine using Montana's labor multiplier 0.97 and material multiplier 0.99. Shell = erected structure; turnkey and finished configs add the items noted.

Cost per square foot
Montana's 98 cost index sits 2% below the national average, which moves every $/sq ft figure below up or down from the national baseline.
| Configuration | Cost per sq ft |
|---|---|
| Pole barn shell | $15 – $29/sq ft |
| Metal building shell | $16 – $33/sq ft |
| Turnkey pole-barn shop | $32 – $71/sq ft |
| Finished barndominium | $100 – $235/sq ft |
Climate considerations
higher ground-snow loads add framing and truss cost.
stronger anchoring and bracing are specified.
some seismic bracing applies in affected counties.
Cold, snowy, and windy, with mountain seismic activity in the west.
Mountain snow loads and strong winds drive design; western valleys near faults add a seismic consideration.
Permit considerations
Statewide code enforced in cities and larger counties; vast rural areas have little or no enforcement.
Agricultural exemptions are widely available. Outside incorporated towns, agricultural and many private buildings face minimal review across this large, rural state.
Permitting rules change and vary by jurisdiction — always confirm with your local building department before you build.
Labor market

Key markets: Billings, Missoula, Bozeman
Bozeman’s resort-driven boom has pushed its labor well above the otherwise modest statewide rates.
Labor is the multiplier that swings most between states, which is why Montana's totals land 2% below the national average. Material prices (lumber and steel) move closer to nationally, so the regional spread you see above is driven mainly by crew rates and availability.
