no fire escape, sprinklers, or roof access-- is this legal?

i'm a renter in a 2-family building and am worried about the fact that 3 people and I occupy the top, 2nd floor in a building that doesn't have a fire escape, sprinklers, only 1 egress, and the roof hatch is nailed closed. i tried searching for this info on google and even here, under building code, but i can't seem to find whether this is legal or not. any insight would be appreciated!
i should mention that everytime i mention this to the landlord and the management company, they're dismissive about it, saying that it's not required in 2 family dwellings.
So are we expected to just jump out the windows, if there's a fire?
