Yes, with one thing to plan around. Wells are shallow here, near 70 feet, which keeps drilling costs down. The ground is mostly flat and drains well, which keeps building simple. NOAA counts about four strong tornadoes a decade within 25 miles, so a storm shelter belongs in the plan.
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 39 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 70 feet deep; a well typically runs $5,000 to $11,000
Growing season
Enough for most vegetables. Start tomatoes and peppers indoors.
About 162 frost-free days, USDA zone 5a; last frost about April 24, first about October 10
Sun
Good sun. Size the array and battery bank for winter.
About 4.7 hours of full sun a day, averaged over the year
Flood
Flood zones run along creeks and rivers here. Look up the parcel on FEMA's flood map.

Wildfire
Low wildfire risk.

Storms
Strong tornadoes are common. A storm shelter belongs in the plan.
NOAA: no hurricane-strength storm within 50 miles since 1975; about 4 strong (EF2 or stronger) tornadoes a decade within 25 miles
Terrain
Flat, but the ground stays wet. Build on the higher, drier spot.
Slopes average about 4%, about 840 feet above sea level
Soil
Good ground for a standard septic system. The county's soil test decides.
Loam, well drained (USDA soil survey). A standard system typically runs $5,000 to $10,000
Road
Paved roads are close by.
Nearest paved road usually within about 0.4 miles (OpenStreetMap)

Linn County zones land outside its towns and publishes its zoning map. Our free lookup shows the district for any address.
Building code
Iowa's state building code applies only where a county or city adopts it (and in cities over 15,000 with no code of their own), so in a county with no code there is no county building permit for a house. The state's energy rules still apply to new homes.
Rainwater
Collecting it is allowed.
Composting toilets
Allowed.
Water rights
Owners of land along a creek or lake can make reasonable use of its water.
Drilled to about 70 feet, with pump and pressure tank
Septic
$5,000 to $10,000
Standard system
Solar and batteries
$18,000 to $34,000
Sized for a modest household
Road or driveway
$3,000 to $8,000
From the nearest road to a house site
Clearing
$1,000 to $4,000
A house site, solar, and garden
Total
$32,000 to $66,000
