Significant challenges
Possible, but water will be hard. Only about 12 inches of rain falls a year, so you will rely on a well or hauled water. The U.S. Forest Service rates wildfire risk high across much of the county, so plan cleared ground around the house.

Zoning
We found no public zoning map for Jefferson County, so call the county planning office with the parcel number to ask whether the land is zoned.
Building code
Oregon's building code applies uniformly statewide, including the Oregon Residential Specialty Code for houses (based on the International Residential Code), and cities and counties cannot set different requirements without state approval. City or county building departments issue house permits and inspect, and the state Building Codes Division does it for some counties.
Rainwater
Collecting it is allowed.
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.
