Maximum nosing protrusion, typically 1.25 inches (32 mm) to prevent people from tripping on the nosing. The general rule is that all steps on the same flight must be identical. The reason is that on a continuous flight of stairs, people get used to a regular step and may trip if there is a step that is different, especially at night. Variance on riser height and tread depth between steps on the same flight should be very low (<3/8″)”. Stair railings on open sides that are 30 inches or more above the surface below shall be equipped with midrails approximately one half way between the steps and the top rail. R308.4.4.1 Structural Glass Baluster Panels In residential applications where the railing span is small, you don’t need to use three panels if the top rail or handrail is large enough to withstand. (b) A stair railing shall be of construction similar to a guardrail (see Section 3209) but the vertical height shall be in compliance with Section 3214(c).
STAIR RAIL CODE CODE
Some building codes also specify a minimum riser height, often 7 1/4 inches (127 mm). The 2018 International Residential Code (IRC) includes a code requirement for residential glass railing that is similar to the wording in the IBC. Minimum tread length, typically 9 inches (229 mm) excluding the nosing for private residences. Mandate handrails if there is more than a certain number of steps (typically 2 risers). Handrails shall be provided on at least one side of each continuous run of treads or flight with four or more risers. Figure 1: The railing extends from the bottom step to the landing, indicating a pass of code Figure 2: The grab rail extends from the bottom step to the landing, so even though the railing on the right does not extend all the way to the landing, it will still pass code because it is just acting as a guard. Handrails adjacent to a wall shall have a space of not less than 1 1/2 inch (38 mm) between the wall and the handrails. Handrail ends shall be returned or shall terminate in newel posts or safety terminals.
STAIR RAIL CODE FULL
Handrails for stairways shall be continuous for the full length of the flight, from a point directly above the top riser of the flight to a point directly above lowest riser of the flight. Maximum space between the balusters of the handrail. The minimum height of a balcony handrail is 36 inches (914 mm) and no more than 42 inches tall. For a rake is typically between 34 and 38 inches (864 and 965 mm), measured to the nose of the tread. Code and Design Assistance Basic Residential Stairway Requirements
