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 Michigan, a month-to-month tenancy is recognized as a form of periodic tenancy where the tenant occupies the property with no definite lease end date and pays rent monthly. This arrangement can be established either through an explicit agreement or by implication 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. For termination of a month-to-month tenancy, either the landlord or the tenant must provide the other party with a 30-day written notice. This notice period is designed to give the receiving party sufficient time to make alternative arrangements. The rules governing month-to-month tenancies in Michigan are generally applicable to both residential and commercial leases. It's important to note that specific local ordinances may also affect the regulation of month-to-month tenancies, so it's advisable to consult with an attorney for detailed legal advice tailored to the specific situation.
