In most apartment buildings, the heat levels are dictated by the landlord. For some unfortunate souls, that means the heat goes off before you even get home from work and you're forced to sleep in multiple layers of stained sweatpants. This is illegal. For inhabitants of the greater New York area, the City Housing Maintenance Code states that heat should be available until May 31. So if you experience a particularly brutal and long winter, your landlord cannot let you freeze to death.
