I would just ask them the possibilities. It can't hurt. I think people down South have an easier time getting these things permitted because
is rarely a factor. Most of the time they are more concerned about high winds, and yurts excel in high wind areas as long as they are properly constructed. Rainier makes excellent yurts and have many years experience in yurt making and even more so, the materials involved. They also provide stamped engineered plans (or at least they used to). Code enforcement types love that!
Keep in mind that the more "alternative" you get, the more push back you may receive. Code enforcement (CE) gets a little uncomfortable when you start talking composting toilets, rain water kitchens, solar ovens, etc.. If it were me, just give the impression that other than it being a yurt, the structure will be otherwise "normal" like other homes. That means it will be wired for AC, plumbed for septic/sewer, etc.. That doesn't mean you can't change that stuff on your own later on, but get your CO first, then worry about that stuff later.
If you don't ask them, you stand to spend a lot more money that you might have to otherwise. For example, they may be perfectly fine with a yurt, as long as it has a second door for egress or at least one standard glass window. If you just up and order one without this, you will have to retrofit the thing, which means you will probably have to hire that out and also chance hurting the yurt.
CE is usually hell bent on getting you approved within their policies, so don't be intimidated. Also, be as pleasant as possible and try to work through issues and don't take the first no as an answer. Keep pushing.
Please let us know how it turned out!
