A month-to-month tenancy outside New York City may be
terminated by either party by giving at least one month's notice before the
expiration of the term. For example, if the rent is due on the first of each
month, the landlord must inform the tenant by September 30th before the
October rent is due that he wants the tenant to move out by November 1st. The
termination notice need not specify why the landlord seeks possession of the
apartment. Such notice does not automatically allow the landlord to evict the
tenant. A landlord may raise the rent of a month-to-month tenant with the
consent of the tenant. If the tenant does not consent, however, the landlord
can terminate the tenancy by giving appropriate notice. (Real Property Law §
232-b)
