The maximum riser height allowed for steps in certain building occupancies is what measurement?

In many building codes, the maximum riser height for steps is set at 7 inches. This measurement is critical for safety and accessibility, ensuring that stairs are comfortable to navigate and reducing the risk of trips and falls. A height of 7 inches strikes a balance between usability and safety, allowing most individuals to ascend and descend without exerting excessive effort or risking injury.

In various building occupancy classifications, a uniform riser height is enforced to promote consistency in stair design, which is especially important in public spaces where individuals with varying mobility levels must be accommodated. The 7-inch maximum is widely recognized in regulations, such as the International Building Code (IBC) and other local guidelines, since it enhances the overall safety in commercial and residential structures alike.

Riser heights greater than 7 inches can lead to discomfort and increased risk of accidents, while shorter riser heights make movements easier, but may not always meet code requirements for all building types. Therefore, adhering to this standard helps ensure that facilities are safe and accessible for all users.
