What is the maximum riser height and minimum tread depth for stairway built in Virginia?

In Virginia, the building code specifies that the maximum riser height for stairs is 8 inches and the minimum tread depth is 9 inches. These measurements are designed to ensure safety and accessibility in stair construction. A maximum riser height of 8 inches helps to reduce the risk of tripping and falling, as taller risers tend to be more challenging to navigate, especially for individuals with mobility issues.

Additionally, the requirement for a minimum tread depth of 9 inches allows for a deeper step, providing a more stable and secure footing when ascending or descending the stairs. These dimensions not only promote safety but also comply with accessibility standards, making it easier for everyone to use stairways comfortably.
