N.Y. Real Property Law § 228: Termination of tenancies at will or by sufferance, by notice

§ 228. Termination of tenancies at will or by sufferance, by notice. A

tenancy at will or by sufferance, however created, may be terminated by

a written notice of not less than thirty days given in behalf of the

landlord, to the tenant, requiring him to remove from the premises;

which notice must be served, either by delivering to the tenant or to a

person of suitable age and discretion, residing upon the premises, or if

neither the tenant nor such a person can be found, by affixing it upon a

conspicuous part of the premises, where it may be conveniently read. At

the expiration of thirty days after the service of such notice, the

landlord may re-enter, maintain an action to recover possession, or

proceed, in the manner prescribed by law, to remove the tenant, without

further or other notice to quit.
