Occupancies are defined and classified as required by the National Fire Protection Association (NFPA) 101 “Life Safety Code” as incorporated by reference in COMAR 29.06.01. In the case of mixed occupancies when it is impractical to distinguish individual occupancy classifications, the occupancy classification is based on the predominant use and occupancy of the building or structure. Terminology and reference standards are defined and classified by the appropriate code or standard of the National Fire Protection Association as referenced in COMAR 29.06.01.
