What is the minimum required width of an accessible stairway between handrails?

The minimum required width of an accessible stairway between handrails is vital for ensuring safe and equitable access for individuals with disabilities. The correct width in this context is 48 inches. This width accommodates not only the passage of individuals using wheelchairs but also allows for the necessary ease of movement and maneuverability around handrails and other obstructions.

A stairway width of 48 inches provides enough space for two users to pass each other comfortably, which is essential for accessibility compliance. This requirement aligns with the standards outlined in the Americans with Disabilities Act (ADA) and other related building codes that emphasize the importance of providing accessible routes.

The other options fall short of this requirement, as they do not provide sufficient space for safe navigation. For instance, a width of 32 inches (the narrowest option) may present significant challenges for users with mobility aids, whereas 36 inches and 42 inches, while more generous, still do not meet the necessary criteria for full accessibility and comfort when navigating stairs.
