Building a one or two step staircase in garage of awkward total rise
A landing is required if the door swings outward, except for screen doors. The landing is to be the width of the door and 36” in the direction of travel. (See ICC R311.4.3.)
The maximum rise of steps is 8”. The maximum difference between risers is 3/8” from smallest to largest. (See ICC R311.5.3.1)
The minimum tread depth is 9”. The greatest difference from smallest to largest is 3/8”. (See ICC R311.5.3.2)
A handrail is required if there are 4 or more risers. The handrail is to be installed a minimum of 34” and not to exceed 38” (See ICC R311.5.6)
