Empty space between ceiling and floor above

[coachgns]

I recently had a leak in my ceiling coming from the apartment above. In order to repair it, the LL had to cut open a hole in my ceiling. Upon doing so I noticed that there is absolutely NOTHING between my Drywall ceiling and the floor of the apartment above me.
Isn't this a fire code violation?
I tried reading the Code, but I couldn't figure that out.

I have complained to my LL about the noise from the Tenant above me from walking on bare floors. These people wake up at 5:30 every morning, and the clomp clomp jolts me awake. They DO try to keep quiet, but there is only so much they can do with a shoe hitting right on hardwood with nothing to absorb the sound.
The lease requires carpeting. They won't carpet. The LL says it is not his problem. "How can I make someone buy carpet", he responds. DUH - HE CAN - There is a LEASE that REQUIRES it. I had assumed there was some insulation between the floors - but now that I see there is Nothing there, I am more upset at the LL than I was before. But I see my only solution is to Move, or spend a small fortune suing the LL.
UNLESS THIS IS A FIRE CODE VIOLATION??? Make the Town force him to insulate between floors.
This is a large apartment building - not in NYC.

What you describe is not a building or fire code violation. This is what exists in most older buildings with floor joists / beams covered in a sub-floor and then, on top of that, wood or other type flooring.
