For instance, if the code mandates a minimum clear width of 36 inches, and there are handrails on both sides, the actual usable width would be 27 inches (36 inches – 4.5 inches – 4.5 inches).

Why Exclude Handrails from Minimum Width?

The rationale behind excluding handrails from the minimum stair width calculation is to ensure sufficient space for users to comfortably navigate the stairs without obstruction. Handrails, while essential for safety, can protrude into the walkway and potentially hinder movement, especially in narrower stairways.

Specific Requirements for Different Occupancies

The minimum clear width requirements can vary based on the occupancy type and the number of people the stairway is designed to serve.

  • Residential: In residential buildings, the minimum clear width is typically 36 inches.
  • Commercial: In commercial buildings, the minimum clear width is generally 44 inches, but it can be reduced to 36 inches for stairways serving an occupant load of less than 50.
  • Egress Stairs: Stairways serving as a means of egress (emergency exit) might have additional width requirements to accommodate the safe evacuation of occupants.

Trends and Considerations

While building codes set the minimum standards, there is a growing trend toward designing staircases with wider clear widths beyond the minimum requirements. This allows for greater comfort, ease of movement, and enhanced accessibility, especially in homes with children, elderly individuals, or those with mobility challenges.

When planning a staircase, it’s important to strike a balance between complying with building codes and ensuring adequate space for safe and comfortable use. Consulting with a qualified professional or architect can help you navigate these requirements and design a staircase that meets both functional and aesthetic needs.

Conclusion

Understanding the distinction between clear width and handrail projection is vital when designing or evaluating staircases. While handrails are essential safety features, they are not included in the minimum width requirements stipulated by building codes.
