month-to-month tenancy

Definition from Nolo’s Plain-English Law Dictionary

A rental agreement that provides for a one-month tenancy that automatically renews each month unless either tenant or landlord gives the other the proper amount of written notice (usually 30 days) to terminate the agreement. Some landlords prefer to use a month-to-month tenancy because it gives them the right to raise the rent after giving proper notice. This type of rental also provides a landlord with an easy way to get rid of troublesome tenants, because in most states (subject to rent control regulations) month-to-month tenancies can be terminated for any reason.
