A facility housing 5 or fewer persons receiving custodial care is classified as what type of occupancy?

In the context of building occupancy classifications, a facility that houses 5 or fewer persons receiving custodial care is appropriately classified as Group R-3 occupancy. This classification is designated for residential occupancies that are typically occupied as a home, including those that provide care to individuals such as those receiving custodial assistance.

Group R-3 is meant to cover residential facilities that are not considered healthcare facilities, fitting the criteria for smaller group homes or assisted living situations where supervision is provided but does not include medical treatment. This designation reflects the intimate setting and support structure typically seen in such facilities, as they primarily function as a residence rather than a medical institution.

In contrast, the other classifications mentioned are intended for larger scale or more institutionalized facilities. Group I-2, for instance, is designed for medical facilities with patients needing medical care for more than 24 hours, while Group I-3 applies to detention and correctional facilities. Group R-4, on the other hand, pertains to small residential care facilities with a slightly larger capacity than what is described in the question. Hence, the Group R-3 classification aligns perfectly with the scenario of housing up to 5 individuals receiving custodial care.
