Get rid of drop ceiling in apartment building?

[Adam Craig]

We are about converting 9000 sq ft of office space into residential apartments on the 2nd level of a commercial building.

Right now its all drop ceiling. Is this a no-no in apartment buildings?

We are pretty much reconfiguring the entire space to get the apartment layouts we want so I figure if we are taking down most of the walls then we should do the ceiling. But the ceiling track is all intact so I want to be 100% sure before we demo.

What are your thoughts on drop ceiling for apartment building? Is it even allowed?
