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 Jersey, a month-to-month tenancy is recognized for both residential and commercial properties. This type of tenancy does not have a fixed end date and continues until either the tenant or the landlord decides to terminate the agreement. Typically, New Jersey law requires either party to provide at least 30 days' written notice to the other party to end a month-to-month lease. However, the notice period may vary based on the terms of the lease or local ordinances. If a tenant remains in the property and continues to pay rent after the expiration of a longer-term lease without signing a new lease, a month-to-month tenancy is often presumed to have been established under New Jersey law. It's important for both landlords and tenants to understand their rights and obligations under this type of tenancy, which may be governed by specific provisions in the New Jersey Anti-Eviction Act and other relevant state statutes.
