The 2002 NEC tells us at 334.10 (1)(2)(3) in which types of construction that NM cable is permitted (Types III, IV, & V). 334.12 does not exclude NM cables in Construction Types I and II. That being true, NM cable is suitable in Construction Types I and II under the 2002 NEC. The 2005 NEC on the other hand at 334.12(A)(1) clarified that NM cable is not permitted in "any dwelling or structure not specifically permitted in 334.10 (1),(2) and (3)."
The State of Michigan has for as long as I can remember allowed NM cable in Construction Types I & II with no 3 floor limitation. This was done via amendment and we have an excellent track record.
