Two kitchens

Is it illegal to have two kitchens in one apartment? We are thinking of moving back in to my parents loft because they are getting old and need help. We would like to live in one half of the loft while my parents live in the other. We would share a common living area. I have gotten a lot of conflicting advice from architects as to whether we would have to amend our CofO or just go ahead and file a plumbing amendment for a dishwasher and a washer/dryer (there is already a utility sink on file with the bldg dept.
Any thoughts?
