Ordered that the order is affirmed insofar as appealed and cross-appealed from, with one bill of costs to the plaintiffs.
The plaintiff Robert E. Levine was 15 years old when he entered premises located at 5 Gould Street in the Village of Great Neck, fell down an abandoned well shaft, and was injured. The defendants Fred Filasky and F. Filasky Sons, Inc. (hereinafter collectively Filasky) were contractors who were hired a week before the accident occurred to demolish buildings on the premises. Filasky admitted that, allegedly with the help of the defendant David S. Khalily, they covered the well with a wooden door and concrete slabs. Evidence was also presented that Filasky may have created the dangerous condition by breaking the concrete cap that had been covering the well.
A contractor may incur liability for an affirmative act of negligence which results in the creation of a dangerous condition ( see, O'Hara v. Patchogue Asphalt Co., 220 A.D.2d 492; Gurriell v Town of Huntington, 129 A.D.2d 768). Moreover, when a person who owes no duty gratuitously acts, that person has a duty to act reasonably ( see, Nallan v. Helmsley-Spear, Inc., 50 N.Y.2d 507; Gordon v. Muchnick, 180 A.D.2d 715). Questions of fact exist as to whether Filasky or David S. Khalily assumed a duty and, if they did so, whether they acted reasonably in exercising that duty ( see, Cohen v. Heritage Motor Tours, 205 A.D.2d 105; Gordon v Muchnick, supra). Furthermore, questions of fact exist as to David S. Khalily's involvement in the premises. Accordingly, summary judgment was properly denied.
