What is a common code requirement for building stairs?

A common code requirement for building stairs is that the rise and run of stairs must be uniform. This means that each step must have the same height (rise) and depth (run), ensuring safety and preventing trips or falls. Uniformity in the rise and run is crucial because if the steps vary in height or depth, it can lead to confusion for users and increase the risk of accidents.

In building codes, the acceptable range for risers and treads is often specified to promote consistent stair dimensions. For instance, a common requirement may state that the rise should not exceed 7.5 inches, and the tread depth should be at least 10 inches, although exact measurements can vary by jurisdiction.

By maintaining uniform dimensions for each step, builders can create a staircase that is comfortable to use and easy to navigate, which is essential for safe ingress and egress in any building.
