The DOB has finally standardized and clarified the rules for a 3-piece bath in a cellar. It’s explicitly permitted under certain limitations:

  1. in a multi family the limitation will be a 5′ by 5′ max. so no room for “powder room”

  2. What about 3 families? Are “powder rooms” allowed in 3 family cellars if all the same conditions are met?

  3. maybe i am dense, but what does this get us? a shower in an open cellar? and why only one and two family dwellings? multiple dwellings have open cellars too.
