Major concerns
Possible, but hard and costly. The growing season is about 129 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 59 inches of rain a year and wells near 90 feet. The U.S. Geological Survey maps strong earthquake shaking here, so build to the seismic code.
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 59 inches a year (30-year average)
Wells
Shallow wells, so drilling should be one of the cheaper costs.
The typical well here is about 90 feet deep; a well typically runs $24,000 to $53,000
Growing season
Short. Start seeds indoors and favor cold-hardy crops.
About 129 frost-free days, USDA zone 6a; last frost about May 23, first about September 30
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.

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.

Collecting it is allowed.
Composting toilets
Allowed.
