No, in Idaho a landlord generally must have legal cause to evict a tenant during the term of a lease agreement, such as nonpayment of rent, a lease violation, property damage, illegal activity, or similar grounds, and must follow the required notice and court process.
If there is no written lease or the written lease has expired and isn’t renewed, the landlord doesn’t need a separate reason to end the tenancy. For periodic tenancies (e.g., month-to-month after a lease ends), Idaho law allows the landlord to terminate the tenancy without cause by giving the required written notice (typically 30 days) and then pursue eviction if the tenant doesn’t vacate.
