A month-to-month tenancy is a periodic tenancy or lease in which the tenant is given possession of the leased premises with no specific expiration date and agrees to pay the landlord on a monthly basis. A month-to-month tenancy often requires the tenant or the landlord to give the other party 30 days written notice of termination of the lease.

Both residential leases and commercial leases may be month-to-month tenancies. If a residential or commercial tenant remains in the leased premises and continues to pay rent following the expiration of a lease for a longer term, there may be a new month-to-month tenancy created and recognized by law.

In Iowa, a month-to-month tenancy is recognized as a type of periodic tenancy where the lease does not have a specific end date, and the tenant pays rent monthly. This arrangement can be established either explicitly through an agreement or implicitly when a tenant remains in the property after the expiration of a fixed-term lease and continues to pay rent, with the landlord's acceptance. Under Iowa law, either party can terminate a month-to-month tenancy by giving the other party a written notice of termination, typically 30 days in advance. This requirement ensures that both the tenant and the landlord have adequate time to make alternative arrangements. It's important to note that the notice period may vary depending on the terms of the lease agreement or if the property is subject to local ordinances that provide different regulations. An attorney can provide specific guidance on the notice requirements and any other legal obligations for month-to-month tenancies in Iowa.
