I am confused as to what rooms are habitable rooms in regards to permitting. According to ASHI
Habitable rooms are living, sleeping, eating and cooking rooms. Common terms for these rooms include living rooms, family rooms, dens, bedrooms, breakfast rooms, dining rooms and kitchens. ... Bathrooms, laundry rooms, closets, storage rooms, equipment rooms and hallways are not habitable rooms.
An answer, to a different question of mine, suggest that calling a room a study or a kids playroom would make in not be considered a habitable space. To me a study seems a lot like a den. Is there a list of room names that are considered habitable. Is there a list of features that make a room be required to have all the other features of a habitable room?
