May I suggest calling the
City Hall in a county that has a piece of
land you're interested in. If you ask to speak to someone regarding building codes & permits, you'll get the right person who can
answer your questions. I'm building a home, and I assumed there are building codes everywhere, but when I walked into city hall to get a building permit, the guy told me I didn't need one, since I was outside of city limits in rural county. He said it came up on a ballot a few years back and the county residents that voted opted out of having building codes outside of city limits. I still had to have an electrical permit & inspection (that's national, and is required everywhere) and a septic permit & inspection, but nothing else.
