§ 232-a. Notice to terminate monthly tenancy or tenancy from month to
month in the city of New York. No monthly tenant, or tenant from month
to month, shall hereafter be removed from any lands or buildings in the
city of New York on the grounds of holding over his term unless at least
thirty days before the expiration of the term the landlord or his agent
serve upon the tenant, in the same manner in which a notice of petition
in summary proceedings is now allowed to be served by law, a notice in
writing to the effect that the landlord elects to terminate the tenancy
and that unless the tenant removes from such premises on the day on
which his term expires the landlord will commence summary proceedings
under the statute to remove such tenant therefrom.
§ 232-b. Notification to terminate monthly tenancy or tenancy from
month to month outside the city of New York. A monthly tenancy or
tenancy from month to month of any lands or buildings located outside of
the city of New York may be terminated by the landlord or the tenant
upon his notifying the other at least one month before the expiration of
the term of his election to terminate; provided, however, that no
notification shall be necessary to terminate a tenancy for a definite
term.
§ 232-c. Holding over by a tenant after expiration of a term longer
than one month; effect of acceptance of rent. Where a tenant whose term
is longer than one month holds over after the expiration of such term,
such holding over shall not give to the landlord the option to hold the
tenant for a new term solely by virtue of the tenant's holding over. In
the case of such a holding over by the tenant, the landlord may proceed,
in any manner permitted by law, to remove the tenant, or, if the
landlord shall accept rent for any period subsequent to the expiration
of such term, then, unless an agreement either express or implied is
made providing otherwise, the tenancy created by the acceptance of such
rent shall be a tenancy from month to month commencing on the first day
after the expiration of such term.
