When is a handrail required for exterior stairs?

A handrail is required for exterior stairs when the stair has more than 3 risers due to safety considerations. This regulation is in place because once the number of risers exceeds three, the potential for a fall increases significantly, especially in outdoor settings where conditions can be less predictable, such as when wet or icy.

Having a handrail provides essential support for individuals using the stairs, helping to prevent falls and ensuring safe passage. This requirement is rooted in building codes and health and safety regulations that aim to minimize risks associated with stair use. The specific threshold of three risers is a standard in many building codes, emphasizing the importance of having a handrail for any configuration that could pose a greater danger to users.

Other considerations, such as the width of the stairs or the intended use, may influence additional safety features, but the fundamental requirement for a handrail is primarily linked to the number of risers.
