I would think every state, county and city would have building codes. I'll have to ask Hubby when he gets home. Doesn't each state have a Licensure Board?
Unfortunately that's not always true. As late as 2001 many towns in Maine had not adopted a code and there was no state-wide requirement. We built a monster house in Winterport in '01 and the town fathers who we invited down fore a look were flabbergasted that we built it so well when we didn't have to.
Doesn't each state have a Licensure Board?
Yes, but each state doesn't license contractors. They're to busy making sure no one braids hair without the proper credentials. Massachusetts does license contractors and there is supposed to be a licensed person with a copy of the code book on site at all times.
