Our client owns an existing Business occupancy building (medical office building use), which we believe to be Type V (000) construction. Exterior, load-bearing wood studs and wood trusses comprise the 1-story structure. A proposed hyperbaric chamber addition is being considered adjacent to this existing structure. Per NFPA 99-2012, there does not appear to be any minimum construction type requirements for a Hyperbaric Facility (nor specific occupancy requirements), yet the chamber and all ancillary service equipment must be protected by 2-hour fire-resistant-rated construction for structures containing Class A chambers.
That said, must a Hyperbaric Facility be classified as a Healthcare Occupancy or if not, is a minimum construction type required for a Business Occupancy, under a Hyperbaric Facility use?
