NYT City Room blog wrote:[New York] City officials also said this will have no impact on subletting because as the law stands, it is already technically illegal to sublet a unit in a residential building for less than 30 days. They also said that law enforcement responds only to complaints and they had no intention of cracking down on individual subletters.
Also, the law does not apply to single-family homes. So your house is safe.
As far as I can tell, for NYC residents nothing will change, and this is one of those cases where the law exists for abuses. The state doesn't give a damn if you want to house-swap or couch surf or take on a boarder for a few days or a couple weeks.
