What is the minimum headroom required for all new construction exit stairs?

The minimum headroom required for all new construction exit stairs is 2.0 meters. This standard is set to ensure that users of the stairway, including individuals with varying heights, can pass through the exit stairs safely and comfortably without the risk of bumping their heads or sustaining injuries. Maintaining a sufficient headroom is crucial for compliance with safety regulations and building codes, which are designed to protect the public in case of emergencies as well as everyday use.

A height of 2.0 meters provides adequate clearance for most individuals, including those who might be carrying objects, ensuring that the exit route remains unobstructed and functional. Furthermore, adherence to this standard is a critical element in the overall safety and accessibility considerations for building design and construction.
