According to building codes, what is the maximum rise for stair treads?

The maximum rise for stair treads is set at 7 inches according to building codes such as the International Building Code (IBC). This regulation is in place to promote safety and usability in stair design. A rise greater than 7 inches can increase the risk of tripping and falling as it makes stairs more difficult to navigate, particularly for individuals with mobility challenges or during emergencies when people may be moving quickly.

The 7-inch maximum rise, combined with a minimum tread depth, ensures that stairs are not only safe but also comfortable to ascend and descend. This standardized measurement facilitates a uniform experience in navigating staircases in commercial buildings. Maintaining these dimensions is essential for compliance and could also affect the overall design and functionality of a building.
