Can you live off-grid in Gilpin County, Colorado?

Major concerns

Possible, but hard and costly. The growing season is only about 111 frost-free days, so plan on cold-hardy crops and a greenhouse. Wells are shallow here, near 140 feet, which keeps drilling costs down. The U.S. Forest Service rates wildfire risk high across much of the county, so plan cleared ground around the house.

Is it legal here?

Zoning
Gilpin County zones land outside its towns and publishes its zoning map. Our free lookup shows the district for any address.
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.
