Help! I need all YURT advice!

[IslandAimz]

(bet you've never come across such a clever subject line huh?)

I'm extremely new to the YURT world but very interested in it being something for me. I'd love any advice anyone can give me.

I'm a new homeowner in Oahu and have a few questions:

1. Can I put a yurt in my backyard as a separate dwelling for a family to live in?
a) If so, how do I go about a permit? Or can it be permitted?

2. It looks like I can save a lot of money buying a used one here on the island, but in the long run to avoid any replacement of parts, would you suggest buying a brand new one?
a) If I buy a used one, where can I buy replacement parts such as the exterior cloth?

3. How do you find the noise level living in a yurt? Can you hear people easily outside, company inside in other rooms, cars outside...etc?

I think that's all for now. Mahalo in advance!
