Buildings that are used for sleeping purposes are classified as ____________ occupancies when they are not classified as a Group I occupancies.

Buildings that accommodate sleeping purposes but do not fall under Group I occupancies are classified as Group R occupancies. This classification encompasses structures such as hotels, motels, apartments, dormitories, and similar dwelling units where people reside or sleep.

The classification into Group R is significant because it outlines specific life safety requirements, including egress provisions, fire-resistance ratings, and other safety measures to protect occupants. This ensures that the design and construction of these buildings accommodate the unique needs of sleeping occupants.

Understanding this classification is crucial as it relates directly to the building code requirements that inspectors must verify during the inspection process. It helps to ensure that the building meets the necessary safety standards to provide a secure environment for residents and guests.

The other classifications mentioned do not pertain to sleeping accommodations in the same way, as Group B typically covers business occupancies, Group M focuses on mercantile spaces, and Group S is related to storage facilities. Each classification has distinct requirements defined by the building codes tailored to the specific usage scenarios, which is why knowing the correct classification is important for compliance and safety.
