2)Can the builder tell you what codes the prefab building you are looking at for your adu is built to?
Each state adopts codes to build by, and HUD builders follow set HUD codes, this simple question should lead to a quick answer from the salesman of what exact codes are being followed, and be able to point out highlights to look at to ensure this is true.
