What is the height limit of a single sprinkler system?

The height limit of a single sprinkler system is identified as 275 feet due to the National Fire Protection Association (NFPA) standards, specifically NFPA 13, which governs the design and installation of sprinkler systems. This height limit is established to ensure optimal performance of the sprinkler system in controlling and extinguishing fires.

Beyond this height, the hydraulic calculations and water supply challenges become increasingly complex. At heights exceeding 275 feet, the pressure required to effectively deliver water to the highest points of a building may not be achievable with standard systems. More sophisticated fire protection strategies would then need to be employed, which might include multiple zones or systems to adequately protect taller structures. This standard is in place to maintain safety and efficacy in fire suppression efforts within buildings of varying heights.
