When is a landing not required on the exterior sides of doors?

A landing is not required on the exterior sides of doors when there are fewer than two risers and the door does not swing over them. This is because the purpose of a landing is typically to provide a safe and stable area for individuals to step onto when entering or exiting a building, particularly when navigating stairs.

When there are fewer than two risers, the height difference is minimal, meaning that the risk of falling or tripping is significantly reduced. Additionally, if the door does not swing over the area where one would step down, this further ensures that there is no obstruction or hazard directly where someone would be landing upon exiting the door.

In contrast, having three or more risers generally indicates a more significant height difference, which necessitates a landing for safety reasons. Similarly, if a door swings over risers or there are seven or more risers, the risk of accidents increases, and proper landings or landing platforms are explicitly required to ensure safe egress.
