Lighthouse met its burden on summary judgment with a prima facie showing establishing as a matter of law that plaintiff did not trip on the sidewalk, but rather on a "gap" between the metal portion of the curb and the concrete portion of the curb, and that Lighthouse neither caused nor created the defect involved in plaintiffs accident ( see Miller v City of New York, 253 AD2d 394, 395-396). Since Administrative Code of the City of New York § 19-101 (d) defines sidewalk as "that portion of a street between the curb lines, or the lateral lines of a roadway, and the adjacent property lines, but not including the curb, intended for the use of pedestrians" (emphasis added), the Lighthouse defendants were not obligated to maintain the curb and are not liable to plaintiff ( see Vucetouic v Epsom Downs, Inc., 10 NY3d 517 [tree well]; Ortiz v City of New York, ___ AD3d ___, 2009 NY Slip Op 06299 [pedestrian ramp]; Fernandez v Highbridge Realty Assoc., 49 AD3d 318 [multiple-flight stairway running between two avenues]). The certified transcript of plaintiffs General Municipal Law § 50-h examination was properly submitted by Lighthouse, as an admission, in support of its motion ( see Morchik v Trinity School, 257 AD2d 534, 536; Claypool v City of New York, 267 AD2d 33, 35).
