What is the maximum vertical rise between floor levels or landings in a stairway?

The maximum vertical rise between floor levels or landings in a stairway is 12 feet, which aligns with building codes and safety standards designed to ensure the accessibility and safety of stairways. A rise beyond this limit can make it difficult for users to navigate the stairs safely, increasing the risk of falls and accidents. Consequently, building codes often stipulate that if a rise exceeds this height, additional measures, such as the installation of landings, must be taken to allow for safe and comfortable use.

While lower rise limits, such as 8 feet, 10 feet, and 14 feet, may suggest varying guidelines, they do not reflect the standard maximum widely accepted in most building codes. Adhering to the 12-foot limit is crucial for maintaining safety in residential and commercial stairway design.
