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.
