There are occasional apartments and other small buildings like storefronts. Most of the larger buildings seem to be where the main missions are going to take place. Like the Madison Field Hospital mission takes place in Madison Square Gardens. You can go on most roofs in the Dark Zone at least. And as far as I know, there is a height advantage mechanic to the game. So if you are higher up than your opponent, you get a damage boost. I don't know 100% about it though.
