Yeah, all of this. I'm pretty sure these cases happen, but that piece of paper ain't it. Also, time to correct these things is dependent on the amount of work to be done, and replacing all basement windows and fixing the electrical wiring especially when multiple units are affected can take a lot of time regardless of how fast the landlord acts (e.g. you need access to every single unit in which the wiring needs fixing in combination with opening up walls and so on). They set a time limit to pay fines, and they will probably be telling them a time frame after which they visit again for inspection where they want to see these things either fixed or what progress has been made towards it.
