Once a lease expires, the tenancy becomes a "holdover" tenancy, and the tenant can continue to stay in the property as long as they continue to pay rent and the landlord allows it. Holdover tenancies are usually treated like month-to-month contracts, and a 30-day notice to renew the lease or move out is the most common procedure in most states. Landlords can also include a clause in their rental agreement detailing the terms of holdover tenancies to prevent future conflicts.
