The primary difference between group I-1 and group I-2 occupancy classifications lies in the level of security required for the occupants. Group I-1 typically includes residential facilities where occupants are capable of self-preservation, such as congregate living facilities or boarding houses. In contrast, group I-2 encompasses medical facilities such as hospitals, where individuals may be incapable of self-preservation due to their physical or mental condition. Therefore, the level of security becomes more critical in group I-2, as these facilities are designed to protect occupants who cannot safely evacuate without assistance.

The understanding of these groups is essential for determining appropriate safety measures, egress requirements, and overall building design to ensure the well-being of the occupants. In practice, distinguishing between the two groups helps stakeholders, including architects, builders, and code officials, allocate resources and plan for emergency response effectively.
