. That is not to say that some tenants have not deceived their landlords and converted space for living purposes without the landlords’ knowledge or tacit approval.
. This gap between June 30,1981 and June 21, 1982, so important in Pilgreen v 91 Fifth Ave. Corp. and Callis v 91 Fifth Ave. Corp. (91 AD2d 565), that Justice Markewich dissented solely over this hiatus, is irrelevant in the case at bar. Here, plaintiff relies exclusively on the new Loft Law, article 7-C of the Multiple Dwelling Law.
. Defendant’s position that the Southeast Chelsea Zone in which 5 West 20th Street is located (whether it be M1-6M or C6-4M) is not capable of administrative certification for residential use is somewhat undermined by a memorandum helpfully supplied by its attorney labeled “Office of Loft Enforcement Memorandum.” This memorandum indeed suggests the applicability of the Loft Law to this very building included within the map of the small area set forth in the memorandum.
. By contrast to the case at bar, the landlord in Lipkis v Pikus (99 Misc 2d 518, affd 72 AD2d 697) collaborated with his tenants in devoting the premises to joint living-working (the leases to the contrary notwithstanding) and the owner in Mandel v Pitkowsky (102 Misc 2d 478, affd 76 AD2d 807) had made preliminary efforts to obtain a certificate of occupancy to legitimize residential use. Eli Haddad Corp. vigorously denies knowledge of or intention to convert to residential use.
