A tenant must give at least 21 daysâ written notice to end the tenancy, unless the landlord agrees to a shorter time (itâs best for this agreement to be in writing). A landlord must give at least 90 days' written notice to end the tenancy, but can give less time (at least 42 daysâ notice) in certain circumstances. If a landlord gives the tenant notice to end the tenancy and the tenant wants to move out sooner, the tenant must still give the landlord 21 daysâ written notice.
