What is the maximum rise of stairs allowed in Illinois?

The maximum rise of stairs allowed in Illinois is 7 to 8 inches as defined by building codes to ensure safety and accessibility. This range helps to create a comfortable and consistent stair step that allows individuals to ascend and descend safely, reducing the risk of trips and falls.

Setting the maximum rise at 7 to 8 inches allows for a balance between practicality and user comfort, as it is steep enough to accommodate space constraints while ensuring stairs are not so high that they become difficult to navigate, especially for people with mobility issues or those carrying objects. This standard is also widely adopted in many building codes across the United States to promote uniformity in construction practices.

The other ranges provided exceed these safety considerations, which could lead to unsafe stair configurations. Hence, adherence to the 7 to 8-inch maximum rise is crucial for ensuring that stairways meet safety standards.
