For example, even assuming the applicability and the violation of the 1922 Building Code § 153(4), the Court finds that this "not significant structural defect" was not a proximate cause of Plaintiff's accident, as the video clearly shows that Plaintiff's accident was caused by her failure to properly place her foot on the top landing without any other contributing factor. (Podel v Glimmer Five, LLC, 117 AD3d 579, 580 [1st Dept 2014]; see also Evans v New York City Tr. Auth., 2016 WL 3646991 [NY Sup Ct, New York County 2016] [Stallman, J.] [finding that the video evidence established as a matter of law that the plaintiff was the sole proximate cause of the accident].) The report of Plaintiff's retained opinion witness, Richard Robbins ("Robbins"), a New York-based architect, states that the "excessive depth of the treads and inconsistent height of the risers" was a "proximate cause" of Plaintiff's fall.
