Ordered that the order is affirmed insofar as appealed from, with costs.
The plaintiff firefighter alleges that the City of New York violated certain provisions of the New York City Fire Department All Unit Circulars, Incident Command System manual provisions, and internal rules concerning, inter alia, classification and inspection of buildings, and that such violations directly or indirectly caused the injuries he sustained in the line of duty. These internal regulations, however, cannot serve as a predicate for liability under General Municipal Law § 205-a, since they are not part of a "well-developed body of law and regulation" imposing clear legal duties or mandating the performance or nonperformance of specific acts ( Galapo v City of New York, 95 NY2d 568, 574 [internal quotation marks omitted]; see Desmond v City of New York, 88 NY2d 455, 464; Fahey v A.O. Smith Corp., 77 AD3d 612 [decided herewith]; Link v City of New York, 34 AD3d 757, 758; Shelton v City of New York, 256 AD2d 611, 612-613; Von Ancken v City of New York, 245 AD2d 286). Therefore, the City established its prima facie entitlement to judgment as a matter of law dismissing the cause of action pursuant to General Municipal Law § 205-a insofar as asserted against it and, in opposition, the plaintiff failed to raise a triable issue of fact.
Accordingly, the Supreme Court properly granted that branch of the City's motion which was for summary judgment dismissing the cause of action pursuant to General Municipal Law § 205-a insofar as asserted against it.
