- R311.4.3 Landings at doors. There shall be a floor or landing on each side of each exterior door. The floor or landing at the exterior door shall not be more than 1.5 inches (38 mm) lower than the top of the threshold. The landing shall be permitted to have a slope not to exceed 0.25 unit vertical in 12 units horizontal (2-percent).
- - Exceptions:
- - - 1. Where a stairway of two or fewer risers is located on the exterior side of a door, other than the required exit door, a landing is not required for the exterior side of the door provided the door, other than an exterior storm or screen door does not swing over the stairway.
- - - 2. The exterior landing at an exterior doorway shall not be more than 73/4 inches (196 mm) below the top of the threshold, provided the door, other than an exterior storm or screen door does not swing over the landing.
- - - 3. The height of floors at exterior doors other than the exit door required by Section R311.4.1 shall not be more than 73/4 inches (186 mm) lower than the top of the threshold.
- - The width of each landing shall not be less than the door
served. Every landing shall have a minimum dimension of
36 inches (914 mm) measured in the direction of travel.
There are three (3) risers at that stair, which means it does not meet the exception and landing is required.
The risers are of different heights and exceed the allowable variation between riser heights.
I doubt that handrail will withstand the loads it is required to withstand. Plus, the lower end juts out and is not returned properly.
That should be a pretty good start.
