Idaho Lease Termination Notice (Month-to-Month)

Idaho Code 55-208 governs termination of a tenancy at will. The landlord may terminate 'by the landlord's giving notice in writing to the tenant... to remove from the premises within a period of not less than one (1) month,' and the tenant may end the tenancy by giving written notice of not less than one month before vacating. The notice must be in writing and served as prescribed by the code of civil procedure. A fixed-term lease ends on its own terms without this notice unless it converts to month-to-month. For no-cause termination of a month-to-month tenancy, this one-month notice—not the three-day unlawful-detainer notices—is the proper mechanism.

No specific statutory penalty. A termination notice shorter than one month is ineffective; the tenancy continues until a proper one-month notice expires, and a landlord cannot pursue eviction for holdover until valid notice has run.
