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 New Hampshire, 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. Both residential and commercial leases can operate on a month-to-month basis. Under New Hampshire law, either the landlord or the tenant can terminate a month-to-month tenancy by providing the other party with a written notice of termination, typically 30 days in advance. This notice period allows both parties to make necessary arrangements for the transition. If a tenant continues to stay and pay rent after the expiration of a fixed-term lease without signing a new one, a month-to-month tenancy may be implied by the tenant's actions and the landlord's acceptance of rent. It's important for both parties to understand their rights and obligations under this type of tenancy to ensure compliance with state statutes and to protect their respective interests.
