Possible, but winter will be hard. The growing season is about 106 frost-free days and winter sun is weak, so plan on a greenhouse and a bigger battery bank or a generator. Wells are shallow here, near 120 feet, which keeps drilling costs down. The ground is steep, with slopes averaging about 25%. That raises the cost of a driveway, septic, and foundation.
What the land says
Rain
Rain helps, but plan on a well for most of your water and on watering the garden in dry months.
About 27 inches a year (PRISM, 1991 to 2020 average)
Wells
Shallow wells, so drilling should be one of the cheaper costs.
The typical well here is about 120 feet deep; a well typically runs $7,000 to $15,000
Growing season
Very short. A greenhouse makes the difference.
About 106 frost-free days, USDA zone 5b; last frost about June 19, first about September 3
Sun
Fair sun. Plan a larger array or a generator for winter.
About 4.1 hours of full sun a day, averaged over the year
Flood
Flood zones are rare here. Still, look up the parcel on FEMA's flood map.
FEMA maps no flood zones nearby
Wildfire
Wildfire risk is high across much of the county. Plan cleared ground around the house and fire-resistant materials.
U.S. Forest Service wildfire hazard map: Moderate to High here
Storms
Hurricanes and strong tornadoes are rare here.
NOAA: no hurricane-strength storm within 50 miles since 1975; no strong (EF2 or stronger) tornado within 25 miles since 1990
Terrain
Steep. A flat house site and a driveway route will drive the cost.
Slopes average about 25%, about 3,380 feet above sea level
Soil
Expect a costlier septic system, because the ground is steep. The county's soil test decides.
Silt loam, well drained (USDA soil survey). A mound, sand filter, or treatment unit typically runs $10,000 to $20,000
Road
Paved roads are close by.

Is it legal here?
Zoning
Rural land here is often unzoned. Confirm with the county before you build.
Building code
Montana's state building code does not apply to a house unless the city, town, or county has adopted it, so where none has, the state issues no building permit for a home. The state energy code still applies to new homes, through the builder's self-certification.
Rainwater
Collecting it is allowed.
Composting toilets
Allowed.
Water rights
Water belongs to whoever claimed it first. A new well or pond may need a state permit, and a creek may already be claimed.
Drilled to about 120 feet, with pump and pressure tank
Septic
$10,000 to $20,000
Mound, sand filter, or treatment unit
Solar and batteries
$18,000 to $34,000
Sized for a modest household
Road or driveway
$3,000 to $9,000
From the nearest road to a house site
Clearing
$1,000 to $4,000
A house site, solar, and garden
Total
$39,000 to $82,000

Soil test
Get a soil test before you count on septic.
Steep ground can rule out a standard system.
Wildfire
Ask an insurance agent whether they will write a policy.
The U.S. Forest Service rates wildfire risk high across much of the county.
Zoning
Confirm with the county whether the parcel is zoned.
