Possible, but water will be hard. Only about 17 inches of rain falls a year, so you will rely on a well (near 270 feet here) or hauled water. The sun is strong, about 6.1 hours of full sun a day, so a smaller solar array covers a household. The ground is mostly flat and drains well, which keeps building simple.

Too dry to live on rain. Plan on a well, and on irrigating anything you grow.

Wells
Typical well depth. Budget for a mid-range well.
The typical well here is about 270 feet deep; a well typically runs $11,000 to $25,000

Enough for most vegetables. Start tomatoes and peppers indoors.
About 157 frost-free days, USDA zone 6b; last frost about May 6, first about October 11
Sun
Strong sun. A modest solar array covers a household.
About 6.1 hours of full sun a day, averaged over the year

Slopes average about 1%, about 4,430 feet above sea level
Soil
Good ground for a standard septic system. The county's soil test decides.
Silt loam, well drained (USDA soil survey). A standard system typically runs $5,000 to $10,000

Is it legal here?
Zoning
Rural land here is often unzoned. Confirm with the county before you build.
Building code
No statewide residential building code: each county decides whether to adopt one, and some rural counties, such as Saguache, have none. State electrical and plumbing permits and inspections still apply wherever the county does not issue its own.
Rainwater
Allowed with limits. Check the state's rules before you size a tank.
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 270 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
$38,000 to $80,000

Zoning
Confirm with the county whether the parcel is zoned.
Rural land in Colorado is often unzoned.
Soil test
Get a soil test before you count on septic.
The county has to approve the ground before it issues a septic permit.
Road access
Confirm the parcel fronts a public road or has a recorded easement.
Without one, you may not have a legal way in.
