In Lord Management Corp. v. Weaver, 11 NY2d 180 (1962), the Court of Appeals determined that premises which were residential prior to February 1, 1947, and which were leased for a non-housing use (physician's office) for the period October 1, 1948 to January 31, 1957, created no new housing accommodation in the sense contemplated by the statute, but merely had the effect of restoring the space to its original status, and so found the premises were not decontrolled under the State Rent and Evictions Regulations Section 9, subdivision 4.
