Handrails for stairs with one side against a wall: Handrail height, measured vertically from the sloped plane adjoining the tread nosing, or finish surface of ramp slope, shall be not less than 34 inches the irc requires guardrails to be at lest 36 in height measured from the deck surface to the top of the rail The guardrail must be 42 inches in height (+/- 3 inches) above the working/walking surface. A horizontal intermediate rail is required and is placed about halfway up. Openings must be less than 19 inches, and intermediate balusters are to be spaced no more than 19 inches apart

The code establishes a maximum vertical height of 151 inches (12 feet 7 inches) between landings or floor levels for a flight of stairs. If the distance between floor levels exceed 151 inches, the flight of stairs would require a level landing somewhere in-between to break up the flight of stairs.

Ramps less than 6″ high do not require handrails. The second way is to keep the slope less than 1:20 or 5%. With a slope less than 5% it is not considered a ramp and therefore.

Improper height: handrails must be installed 34 - 38 above the sloped plane of the stairway. In other words, measure up from the end of the treads.

A stair riser is the back, vertical part of a step. Staircase riser height translates to the distance you move your foot either up or down from one step to an adjacent step. This should be no more than 7 3/4 inches The stair railing should include a graspable handrail in most cases. Openings in the railing should be no larger than 4 3/8 inches between balusters, and 6 inches between the bottom rail and the tread, as seen in the illustration. Stringers should be spaced close enough to adequately support the treads. This spacing depends on the tread materials Vertical components, such as railing systems, get less sun exposure and less wear and tear than decking, so they tend to stand up well over time. A flat 2×6 used for the top railing that is neither sloped or chamfered is, however, prone to the same type of cupping and checking that affects decking boards R311.5.6 Handrails: Handrails shall be provided on at least one side of each continuous run of treads or flight with four or more risers.
