What is the maximum riser height allowed in stairs?

The correct answer is 8 inches 1/4. This is based on building codes that regulate the construction of stairs, which typically specify maximum riser heights to ensure safety and accessibility. An 8-inch 1/4 maximum riser height strikes a balance between comfort and safety, allowing for easier ascent and descent while minimizing the risk of accidents.

Construction codes often dictate that riser heights should not exceed this measurement to help accommodate a wide range of users, including those with mobility challenges. These standards are in place to create consistent and safe stairways in residential buildings and are important for compliance with local building regulations.

The other options reflect lower heights that, while within their own contexts may be acceptable, do not represent the maximum allowable riser height as per the current standards stated in the codes. It's essential to adhere to the established guideline of 8 inches 1/4 to ensure both legal compliance and the safety of those using the stairs.
