this is in response to your questions regarding models in the 'Tipi' thread.
your floor joists can be as far apart as you like, but the decking has to be able to take the moment of the 40#/SF you put on it.
Same for your rafters, even if you have no snow load, you should design to a minimum of 25#/SF.
For a shed, I don't think you need a permit for less than 200 sf where you live (here it is 120 SF). I built a shed with a steep pitch roof (stick frame). I used 2x6s on 16" centers + 1/2" ply sheathing. Total span of 5' (10x12 shed).
Anyway, I won't attempt to engineer your entire project here (for free). feel free to give me a shout to stressman79@hotmail.com. It is my SPAM accout, so it may be several days until I reply.
