Dear NFPA staff,
Good day! I have a question regarding staircase landings. According to section 220.127.116.11.2.3, in new buildings, every stair landing shall have a dimension, measured in the direction of travel, that is not less than the width of the stair.
In respect to this section, I need to clarify whether the landing needs to be continuous between the two sections of a same staircase or if it the landing can be divided by a rung to the center, as shown in the attached image. The red line crossing the landing transversely in Image N°1 represents a rung with the same width as the stair.
Image N°1. Staircase landing with a transverse rung.
Thanks for the attention given to this inquiry.
