I have a building to wire that is 3 stories. The original building (combustible) takes up the first 2 floors and half way back where add ons were constructed (non-combustible) for the back portion and the upper 3rd floor. the first floor is commercial space, and the top 2 floors are residential units. The residential units have been fire seperated from the common areas and the commercial space. is in ok to use NMD for these residential spaces and if so where in the Ontario or Canadian building code does it say its ok. All I found in Part 9 stating that except dwelling units nmd has to be used in combustible construction.
