A Manhattan landlord cannot deregulate a rent-controlled apartment by considering the income of a spouse who had moved into an assisted-living facility, a New York appeals court has ruled.

The Appellate Division, First Department, affirmed a 2015 decision by Manhattan Supreme Court Justice Joan Lobis, and an order of the state Division of Housing and Community Renewal, which had preserved rent control on a unit at 315 Central Park West occupied by Margaret Friedman.
