Seeing the other question got me to thinking about the shed I plan to build
My land is shale with 0-10 inches of dirt on top.
I don't know, but it seems to me that shale isn't going to go anywhere, so a
minimal foundation will be adequate, perhaps even less than the 4" of gravel
and 4" of concrete the other guy was talking about?
My county has a policy; if you leave them alone, they leave you alone. I
don't know what code requires, and I bet the building inspector doesn't
either. In a neighboring county I went through a new house that had
significantly less insulation than the state requirement. I called the
building inspector, he looked it up and said it was news to him. I mean,
geez, insulation is about as basic as it gets.
