Multiple Occupancies – Construction Type

This regulation addresses construction type requirements for buildings with multiple occupancies, specifying that the most stringent construction type applies throughout unless a two-hour fire separation is provided, in which case construction types are determined separately for health care occupancies and other occupancy areas. It references NFPA Life Safety Code sections governing health care facility construction standards.
