At what height must a building have a sprinkler system installed, according to local regulations?

A building is required to have a sprinkler system installed when it reaches a height of 4 stories or 15 meters due to fire safety regulations aimed at ensuring adequate fire protection for higher structures. This requirement is based on the increased risk factors associated with taller buildings, such as the complexity of evacuation and the difficulty for firefighters to access upper levels in the event of a fire.

Buildings below this height may not present the same level of risk, allowing for different fire protection requirements. The regulation is set to reduce the chances of fire spreading and to enhance safety for both occupants and emergency responders. This ensures that any potential fire incidents can be managed more effectively in taller buildings, where the impact of a fire can be more severe due to greater occupancy and structural challenges.
