For a stairway with how many or more risers should a handrail be present on at least one side?

A handrail is required for stairways with four or more risers to ensure safety and provide guidance for users. This requirement is based on building codes that aim to minimize the risk of falls on stairs. When there are four or more risers, the height and potential difficulty in ascending or descending the stairs increase, making it crucial to have a handrail for support.

The presence of a handrail aids in stabilizing individuals as they navigate the stairs, offering a necessary grip to prevent accidents. It is particularly important for those who may have mobility issues, children, or individuals carrying objects that make it harder for them to maintain their balance.

While a handrail is beneficial for shorter staircases with fewer risers, building codes typically don't mandate them unless the stairway exceeds three risers, which reinforces the decision to specify that handrails become a requirement starting with four risers. This regulation emphasizes the importance of safety standards in construction and design.
