An automatic sprinkler system must be provided in buildings with 2 or more stories above grade plane that contain a repair garage greater than what size?

An automatic sprinkler system is mandated in buildings with two or more stories above grade plane when the repair garage exceeds a certain size to ensure fire safety and protection for both the structure and the occupants. The requirement of 10,000 square feet as the threshold is based on fire safety standards, which recognize that larger areas present a greater risk of fire due to the potential for larger quantities of flammable materials and equipment present in repair garages. By requiring a sprinkler system in such instances, the likelihood of controlling fires before they can spread is significantly increased, thereby enhancing the overall safety of the building and its users.

Choosing 10,000 square feet aligns with codes that factor in fire load, occupancy risk, and response time for firefighting efforts. Often, standards are put in place to harmonize safety protocols across various situations, ensuring that buildings serving specific functions that may involve heightened fire hazards are adequately protected.
