I don't think the actual code differs anywhere - but the AHJ (the inspector) often takes nuances into account. The best example is the definition of a garage. I added a garage ONTO my garage, which was meant as a shop. The building official allowed me to install a pellet stove in there. For purposes of that part of the code, my guess would mean that it means no wood stoves in a "standard" attached garage which is used for cars and such.
