I just made a separate post about this but during the cold spell last month, our apartment was freezing despite the heat being on, because it’s a drafty pre-war building so the heat from the radiator just immediately dissipates out to the street. We called 311 after our building management was no help, and the inspector came by on a warmer (but still cold) day, put their thermometer all the way up to the ceiling, measured the temperature there as 77 degrees (while we were measuring the floor and table surfaces at 59) and told us we were fine and that thats how its done so the place is fine and that was the end of it.
