A residential ____________ occupancy includes buildings used by more than 5 persons (16 max) who reside on a 24 hr basis in a supervised residential environment and receive custodial care.

The correct answer relates to the classification of a residential occupancy typically designated for facilities providing care and supervision for individuals. Specifically, Group R-4 is defined in building codes for residential occupancies that accommodate more than five persons who live under supervision and receive custodial care on a 24-hour basis, such as assisted living facilities or group homes.

Group R-3 refers to small residential occupancies, primarily single-family homes, and does not account for the level of supervision or custodial care defined in the question. Group I-2 focuses on facilities like hospitals and nursing homes, where occupants are not housed in a residential setting but rather in an institutional context. Group I-3 pertains to buildings designed for detention and correctional purposes, emphasizing security rather than residential living conditions.

Thus, Group R-4 accurately captures the essence of the occupancy described, ensuring that it aligns with the requirements for supervised residential environments accommodating individuals in need of custodial care.
