Final answer:
A tenancy at will can be terminated by either the landlord or tenant with a 30-day written notice. Failure to comply with this notice can result in additional charges, and inability to provide possession allows for agreement cancellation.
Step-by-step explanation:
The concept in question, tenancy at will, refers to a legal agreement between a landlord and a tenant that either party can terminate at any time. According to the provided reference, the termination of a tenancy at will requires a 30-day written notice by either party. It is important to note that the specifics of this notice period can also be influenced by local laws, which might require a "just cause" to be stated in the termination notice.
If a tenant overstays the termination date or fails to remove their possessions by that time, they can be held liable for additional rent and damages, including any potential loss the landlord incurs due to missed opportunities with new renters. Conversely, if the landlord cannot deliver possession of the residence to the tenant by the agreed date, either party can terminate the agreement with a written notice and all paid sums will be refunded.
