Romex and occupancy types
I'm bidding on a multi-building apartment complex where there are two kinds of buildings:
- Building 1: occupancy type R-2, construction type 5-B (all apartments)
- Building 2: occupancy type A-3, B and R-2, construction type 5-B (community center, main office, and apartments)
Are there any codes (NEC or other) that will prevent me from bidding this whole project in NM?
Thanks!

Drop ceilings is not a factor . Plenum space is a factor

Outside of Mass, suspended ceilings are a factor for NM cable in commercial spaces.
334.12(A)(2) prohibits NM cable from being installed exposed in dropped or suspended ceilings in other than dwelling units.

That Bites! Usually most amendments seem to increase material cost and labor . Here is one that lowers costs:
Mass does not restrict you to three floors . You can use Nm in a six story apt bldg for example as long as you use the Nm within the Dwelling unit . Between floors and in hallways ect are not allowed.

Romex® Type NM cables are approved for multi-family dwellings up to 5 stories of construction types III, IV and V. The office should fall under the same classification. The community center could be considered a place of assembly in which it would be governed by NEC 518.1 for buildings or portions of buildings designed for the gathering of 100 or more people for deliberation, worship, entertainment, eating, drinking and so on. Your best bet would be to contact your local jurisdiction authority and ask how they would classify that area of the building. They have the final say in this kind of application.
