A building that provides sleeping facilities for four or more residents and is occupied by persons who are prevented from protecting themselves because of security measures not under their control, is classified as:

• A. A lodging occupancy.
• B. An occupancy of unusual structure.
• C. A transient occupancy.
• D. A detention and correctional occupancy.

Answer: (C)

The main idea here is how fire codes classify a building based on how it’s used for sleeping and how long people stay. Transient occupancy covers sleeping facilities used for short stays by people who aren’t residents for long periods—think hotels, motels, or other lodging where guests come and go.

This scenario fits that pattern: a building provides sleeping facilities for four or more residents, and the occupants are there for short-term stays rather than as long-term residents. Even if security measures exist to control access, that doesn’t change the fundamental use of the space into detention; the primary purpose is temporary sleeping accommodations for guests. Therefore, the best classification is transient occupancy.
