What does the Residential Building Code require for stairway design?

The Residential Building Code mandates that stairway design includes specific dimensions, handrails, and safety features to ensure both safety and accessibility. These regulations are in place to minimize the risk of accidents and to accommodate users of all abilities.

For instance, the code typically specifies the minimum and maximum width of the stairway, the height and depth of treads, and the rise of the risers to facilitate safe usage. Handrails must meet certain height requirements and be designed to provide a secure grip. Additional safety features might include requirements for lighting, landings, and the prevention of tripping hazards.

By adhering to these specifications, builders create stairways that are not only functional but also safe for occupants, thereby addressing potential hazards that could arise from poorly designed stairways. The other options do not encompass the comprehensive safety and dimensional standards required by building codes.
