"'[a]n elevator company which agrees to maintain an elevator in safe operating condition may be liable to a passenger for failure to correct conditions of which it has knowledge or failure to use reasonable care to discover and correct a condition which it ought to have found'" (id., quoting Rogers v Dorchester Assocs., 32 NY2d 553, 559 [1973]; see also Bonifacio v 910-930 S. Blvd., 295 AD2d 86, 88 [1st Dept 2002], citing Rogers, 33 NY2d 553] [although its "liability under this statute is nondelegable, [] the owner may in turn look to a party with whom it contracted for the maintenance of the premises" for indemnification]).
