Floor drain in cellar

Can someone help me understand whether or not plumbing code in NYC requires a floor drain in the cellar of a 3 story 2 family brownstone. I don’t have one and haven’t seen one in others, but my brownstone hasn’t had any work on it in a long time. If code does not require it, then how does a hot water boiler contain any possible overflow?
thanks
