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 Louisiana, a month-to-month tenancy is recognized as a form of periodic tenancy where the tenant occupies the property without a definite lease term but continues to pay rent on a monthly basis. This arrangement does not have a specific end date and can continue indefinitely until either the tenant or the landlord decides to terminate the tenancy. To end a month-to-month tenancy in Louisiana, either party is typically required to provide a 30-day written notice to the other party. This applies to both residential and commercial leases. If a tenant remains in the property and continues to pay rent after the expiration of a fixed-term lease without signing a new lease, a month-to-month tenancy is often presumed to have been established under Louisiana law. It's important to note that the exact notice period and terms of termination may be subject to the provisions of the original lease agreement and local regulations.
