Possible, but winter will be hard. The growing season is about 133 frost-free days and winter sun is weak, so plan on a greenhouse and a bigger battery bank or a generator. The ground is steep, with slopes averaging about 17%. 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 28 inches a year (PRISM, 1991 to 2020 average)
Wells
Typical well depth. Budget for a mid-range well.
The typical well here is about 170 feet deep; a well typically runs $9,000 to $20,000
Growing season
Short. Start seeds indoors and favor cold-hardy crops.
About 133 frost-free days, USDA zone 6b; last frost about May 17, first about September 29
Sun
Fair sun. Plan a larger array or a generator for winter.
About 4.4 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
Low wildfire risk.
U.S. Forest Service wildfire hazard map: Very Low to Moderate 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 in places. Driveways, septic, and foundations cost more.
Slopes average about 17%, about 2,840 feet above sea level
Soil
Expect a costlier septic system, because rock or a hard layer sits about 31 inches down. The county's soil test decides.
Silt loam, moderately 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
We found no public zoning map for Latah 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.
Drilled to about 170 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 $5,000
A house site, solar, and garden
Total
$42,000 to $88,000

Soil test
Get a soil test before you count on septic.
Rock or a hard layer sits about 31 inches down, which can rule out a standard system.
Zoning
Call the county planning office with the parcel number.
There is no public zoning map, so we cannot tell whether the land is zoned.
Road access
Confirm the parcel fronts a public road or has a recorded easement.
Without one, you may not have a legal way in.
