I lived in Klamath County a few years back. I talked to the county about natural building, as I was interested in it but never ended up acting on it. Basically, they are happy to approve anything a certified engineer has signed off on. There are several straw bale buildings in the county, but the owners had to hire an engineer to review their blueprints and vouch that they were structurally sound. My memory is fuzzy, but it's either 150 or 200 square feet, such that if you build anything smaller than that you don't need a permit either. So, you can build outbuildings or maybe even a tiny home, without a permit at all, though if it has plumbing it may need a permit at any size. It was 5ish years ago, so I don't remember details. And of course you can always go rogue and proceed without a permit, then ask forgiveness if you get caught.
