DECISION ORDER
ORDERED that the order is affirmed, with costs.
The plaintiffs allege that the defendants were negligent in failing to install a smoke detector in an apartment where a fire occurred. The defendants met their initial burden of establishing their entitlement to judgment as a matter of law (see generally Winegrad v. New York Univ. Med. Center, 64 N.Y.2d 851) by submitting both a signed form acknowledging the installation of a smoke detector in the subject apartment, and an affidavit from the building manager identifying the signature on the form as the tenant's. This evidence established that the defendants did not breach any duty to the plaintiffs (see Administrative Code of City of N.Y. § 27-2045; Acevedo v. Audubon Mgt., 280 A.D.2d 91).
In response, the plaintiffs failed to raise a triable issue of fact requiring a trial of the action. The plaintiffs relied on hearsay evidence without justifying such reliance (see Zuckerman v. City of New York, 49 N.Y.2d 557), and submitted an expert's affidavit containing only bare conclusory allegations and assuming facts not supported by the evidence (see Mendez v. City of New York, 295 A.D.2d 487). Therefore, the Supreme Court properly granted the defendants' motion for summary judgment dismissing the complaint.
In light of the foregoing, we need not reach the parties' remaining contention.
ALTMAN, J.P., SMITH, McGINITY and TOWNES, JJ., concur.
