NFPA Rules Governing Exits from Existing Business Occupancies
MTAS was asked to clarify the NFPA Rules governing exits from existing business occupancies, such as city and town halls.
Knowledgebase-NFPA Rules Governing Exits from Existing Business OccupanciesApril 30, 1997 Here are the NFPA Rules governing exits from existing business occupancies. Under NFPA 101: 4-1.8, city and town halls are business occupancies. Note also that under NFPA 101: 4-1.0, “Minor storage incidental to another occupancy shall be treated as part of the predominant occupancy.” From you description of the storage area, it is qualifies as minor storage. However, because the city hall is also used by what is essentially a private group, you may have a mixed occupancy under NFPA 101:4.1.11, depending upon the extent and nature of the use. In that case we may have to go further to determine the exit requirements for that use. The egress requirements are contained in NFPA 101:27-2, the arrangement of the means of egress are contained in NFPA 101:27-2.5, and the travel distance to exists are contained in NFPA 101:27-2.6.
