Great answer(s)(s)!! but you know great answers always spawn more questions.
First, where did you get that list?
International building code, and International residential code, are these what architects use to spec. building components?
Before I assault you with any more questions, I'll explain:
A contractor I wire room additions for has asked me to do his drawing for him in AutoCAD. I'd love to. I love AutoCAD and don't have enough reasons already to use it. So I'll draw them and if the village requires an arch. stamp, he'll have it reviewed and stamped. But I want to draw them so they need no revision, but I don't want to overbuild it just because I don't know any better.
I have plenty of similar room plans that have already been built to look at for reference. I would however prefer to double-check requirements. I have seen it plenty of times when an arch. doesn't know the NEC, they over-spec it to cover themselves.
Plus I have grumbled before with other trades about how the print we are looking at can't or shouldn't be built that way, and how I have always thought it should be a requirement for arch.'s and engineers to spend a few years in the field with tools as part of their internship. Not that I'm on my way to becoming an arch., but now is my chance to draw a plan the way it is actually going to be built.
