Possible, but hard and costly. The ground is steep, with slopes averaging about 28%. That raises the cost of a driveway, septic, and foundation. Wells are shallow here, near 140 feet, which keeps drilling costs down. The growing season is only about 126 frost-free days, so plan on cold-hardy crops and a greenhouse.
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 25 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 140 feet deep; a well typically runs $8,000 to $17,000
Growing season
Short. Start seeds indoors and favor cold-hardy crops.
About 126 frost-free days, USDA zone 6a; last frost about April 28, first about October 7
Sun
Good sun. Size the array and battery bank for winter.
About 4.8 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; about 0.3 strong (EF2 or stronger) tornadoes a decade within 25 miles
Terrain
Steep. A flat house site and a driveway route will drive the cost.
Slopes average about 28%, about 4,070 feet above sea level
Soil
Expect a costlier septic system, because rock or a hard layer sits about 25 inches down. The county's soil test decides.
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.
Nearest paved road usually within about 0.8 miles (OpenStreetMap)

Is it legal here?
Zoning
We found no public zoning map for Adams County, so call the county planning office with the parcel number to ask whether the land is zoned.
Building code
Idaho's residential code (the 2018 International Residential Code with state changes) is enforced only by cities and counties that choose to run a building permit program; where a county has none, there is no county building permit for a house.
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.
