I live in Massachusetts, my existing house has battery smoke detectors and carbon monoxide detectors. I'm considering adding a two car garage, with a room above and attaching to my house. If this is done, do I now need smoke detectors in every bathroom and also additional one's on every level hard wired. Also will the carbon monoxide detectors need to be hard wired and also will I need to hard wire heat dectors into the garage?
