Household.
Household. For purposes of this subpart, we consider a household to be a personal place of residence. A commercial establishment such as a hotel or boarding house is not a household but a household can exist within a commercial establishment. If you live in a commercial establishment, we do not automatically consider you to be a member of the household of the proprietor. You may, however, live in the household of a roomer or boarder within the hotel or boarding house. An institution is not a household and a household cannot exist within an institution. (Institution is defined in 416.1101.)
