Does any one have problems with running NM cable in small commercial wood frame buildings (say a apartment complex office/community center (less than 100 people)) as opposed to MC cable?
Is the cost savings (material and labor) significant?

I might be wrong,but I thought Romex was not allowed in any commercial building.

Is a condominium or apartment complex above three stories considered commercial or residential?

Based on your information, it's not an NEC issue.
Personally, I (as an EC) do not put MNC in comm buildings. But, remember, this is my personal choice.

we just wired up a one story medical building. we ran romex for the offices, kitchen, reception, and waiting rooms; and BX for the examination rooms...if there wern't any examination rooms, i am positive my boss would have ran all romex(speed/cost of running the wire, ect.)if it's not over 3 stories then go for it...just don't run it in open runs above a drop ceiling.
for a complete list of where you are allowed to use NM cable, look at
Article 334.10--Uses Permitted.
for complete list of where you can't use it look at Article 334.12--Uses Not Permitted

Depends on your local codes for fire ratings, I'd check your Inspector before you start.

I don't have a problem using NM in any wood frame construction.

BTW, the 3 story limit was removed in the 2002 book.
