Major concerns
Possible, but hard and costly. The growing season is about 128 frost-free days and winter sun is weak, so plan on a greenhouse and a bigger battery bank or a generator. Water is easy here, with about 100 inches of rain a year and wells near 40 feet. The ground is steep, with slopes averaging about 36%. That raises the cost of a driveway, septic, and foundation.
What the land says
Rain
Rain can supply much of a household's water with a large tank. A garden mostly waters itself in normal years.
About 100 inches a year (30-year average)
Wells
Shallow wells, so drilling should be one of the cheaper costs.
The typical well here is about 40 feet deep; a well typically runs $24,000 to $53,000
Growing season
Short. Start seeds indoors and favor cold-hardy crops.
About 128 frost-free days, USDA zone 6b; last frost about May 27, first about October 3
Sun
Weak sun. Solar needs a generator behind it in winter.
About 2.7 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 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
Earthquakes
Strong shaking is possible. Build to the seismic code and brace the water tank.
USGS seismic hazard map: very high
Terrain
Steep. A flat house site and a driveway route will drive the cost.
Slopes average about 36%, about 680 feet above sea level
Soil
Expect a costlier septic system, because rock or a hard layer sits about 20 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

Is it legal here?
Zoning
Rural land here is often unzoned. Confirm with the borough before you build.
Building code
Alaska has no statewide building code for one- to three-family homes, so a house needs a building permit only where a city or borough, such as Anchorage, has adopted its own code. Homes financed by Alaska Housing Finance Corporation must still meet state construction standards and pass inspections.
Rainwater
Collecting it is allowed.
Composting toilets
Allowed.

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 40 feet, with pump and pressure tank
Septic
$10,000 to $20,000
Mound, sand filter, or treatment unit
