A building occupied by more than how many persons who receive custodial care for fewer than 24 hours a day is classified as Group I-4?

In the context of building classification, Group I-4 pertains specifically to facilities utilized for the care of individuals who are not permanently residing there, such as day-care facilities for children or adults. The classification is determined by the number of individuals receiving custodial care for less than 24 hours per day.

The correct answer identifies that a building is classified as Group I-4 when it accommodates more than five persons. This is significant because this threshold helps differentiate between larger facilities that require stricter safety and compliance measures compared to smaller, potentially less complex environments.

Buildings that care for a small number of individuals, like one or two, may not pose the same level of risk or require the same comprehensive safety features as those caring for larger groups. Thus, establishing this cutoff at five individuals necessitates increased attention to safety protocols, emergency planning, and overall design standards to ensure the wellbeing of all occupants in a communal setting.
