How does the exit access travel distance differ for buildings equipped with an automatic sprinkler system compared to those without, as outlined in the 2018 International Building Code?

In buildings equipped with an automatic sprinkler system, the exit access travel distance is generally increased compared to buildings without such a system. For example, in occupancy groups like A, E, F-1, M, R, and S-1, the distance increases from 200 feet to 250 feet when a sprinkler system is present. In Group B occupancies, the distance increases from 200 feet to 300 feet with a sprinkler system.

The 2018 International Building Code outlines specific differences in exit access travel distances for buildings with and without automatic sprinkler systems. Generally, the presence of a sprinkler system allows for longer travel distances before reaching an exit. For instance, in occupancy groups such as A, E, F-1, M, R, and S-1, the maximum travel distance increases from 200 feet to 250 feet when a building is equipped with a sprinkler system. Similarly, in Group B occupancies, the travel distance increases from 200 feet to 300 feet with a sprinkler system. These increases are due to the enhanced safety provided by the sprinkler system, which helps control fire spread and provides additional time for occupants to evacuate safely.
