Generally in the USA the halls are heated but each unit has their own thermostat with which to control the heating of their own unit. It’s okay to open a window when your unit’s heating is off, if it gets too bad then try to circulate the air, and if it’s still not enough call the landlord about it and demand something gets done about it.

That wasn’t how it worked in the apartments I had in Manhattan. Probably other cities are different as you point out.
