To find building codes, you may need to check at the local, state, and federal levels. The state building code sets the minimum standards for the state, but local governments can have more stringent standards. Federal standards may also apply in some situations. Many states, New Hampshire included, adopt "model codes" and then adapt them for their own use. That's why it's never enough just to read the model code. You must also look for any state or local amendments to the model code and read them together.
