For Group A-5 occupancies in accessory use areas, what is the minimum size that triggers the need for an automatic sprinkler system?

For Group A-5 occupancies, which typically include venues for assembly with a focus on recreation or entertainment, the requirement for an automatic sprinkler system is determined by the size of accessory use areas. In this context, accessory uses are those that support the primary function of the occupancy.

The threshold for requiring a sprinkler system in accessory use areas is set at 1,000 square feet. This size is critical because it reflects a level of occupancy and potential fire risk that necessitates additional safety measures. By mandating a sprinkler system for spaces that exceed this size, the regulations aim to enhance safety for occupants in the event of a fire, providing critical time for evacuation and minimizing property damage.

Options representing sizes smaller than 1,000 square feet do not invoke the same level of risk and therefore do not require sprinklers under the code. Likewise, larger size thresholds like 1,500 or 2,000 square feet exceed the point at which the code seeks to mitigate fire hazards proactively, as it is essential to implement protective measures at the critical size of 1,000 square feet, mitigating risk effectively in those spaces most likely to pose a danger if a fire occurs.

Thus, recognizing 1,000 square feet as the minimum size
