Welcome. My name is XXXXX XXXXX would be glad to assist.No where in the code does it state anything on a "dried in" building.That is what most localities call it based on the uses of the NM cable itself.If it is not dried in per se, then it is exposed to the weather and elements which can be very detrimental to the NM cable and its internal paper liner and insulation on the wires themselves.That part is all based on the code:334.15(B) Types NM and NMS. Types NM and NMS cablesshall not be used under the following conditions or in thefollowing locations:(1) Where exposed to corrosive fumes or vapors(2) Where embedded in masonry, concrete, adobe, fill, orplaster(3) In a shallow chase in masonry, concrete, or adobe andcovered with plaster, adobe, or similar finish(4) In wet or damp locations
Once the building is "dried in", then the elements are no longer a threat to the cable etc.
