When can a Group B space have a single exit?
§01ANSWER
A Group B (business) space may have one exit where the occupant load does not exceed 49 and the common path of egress travel stays within the limit in Table 1006.2.1.
Single-exit spaces are governed by occupant load and common path of egress travel, not floor area alone.
For Group B with a sprinkler system, the common path limit is generally 100 feet. Confirm the value for your specific configuration in the table.
