Which occupancy classification corresponds to institutional structures?

Occupancy classifications are used in building codes to categorize structures based on their intended use and the potential hazards associated with that use. Institutional structures, such as hospitals, nursing homes, and correctional facilities, fall under Group I occupancy classification.

This classification is specifically designed to address the unique needs and safety requirements of buildings where individuals may be cared for, monitored, or detained. For instance, these facilities often require special provisions for evacuation, fire safety, and security due to the vulnerable populations they serve.

The other classifications do not pertain to institutional settings. Group R classifications generally relate to residential occupancies, Group S refers to storage facilities, and Group U covers utility and miscellaneous structures. Therefore, Group I is clearly the most suitable designation for institutional structures, highlighting the specialized concerns related to health, safety, and supervision required in such buildings.
