For single-family dwellings with occupant load less than 10, what is the minimum tread run for stairs (excluding spiral stairs)?

• A. 9 inches
• B. 10 inches
• C. 11 inches
• D. 12 inches

Answer: (B)

For single-family dwellings with an occupant load of less than 10, the minimum tread run for stairs is established to ensure safety and accessibility. The correct minimum tread run of 10 inches is in line with building codes that focus on creating a comfortable and safe experience for the occupants. The 10-inch requirement allows for an adequate surface area for individuals to step fully onto the tread, reducing the risk of slips and falls. This standard takes into account the average size of adult shoes and promotes a safer stair climbing experience, particularly in residential settings where the traffic is typically lower, but safety still remains a priority. In the context of building codes, traits such as ease of use and stability are essential, particularly in residential buildings where occupants may include children or elderly individuals. Thus, the specification of a minimum tread run allows for compliance with safety standards while accommodating various users. In contrast, while larger tread runs might provide extra comfort, they are not necessary for dwellings with such a limited occupant load, making the 10-inch requirement both practical and sufficient.
