Hotel suites that provide a sleeping area that is separate from the living area are covered by the RRP Rule because they are not zero-bedroom dwellings.  A zero-bedroom dwelling is a residential dwelling in which the living area is not separated from the sleeping area.  The term includes efficiencies, studio apartments, dormitory housing, military barracks, and rentals of individual rooms in residential dwellings.
