A periodic agreement continues indefinitely until the tenant or property manager/owner gives notice to end it.
Fixed term agreements
No new agreement: if the tenant has not been given notice to leave and a new agreement has not been put in place, the tenancy continues as a periodic agreement under the same terms and conditions of the original agreement.
No changes to the agreement: the tenant and property manager/owner can sign a letter or statement with the new dates.
Changes to the agreement: a new tenancy agreement will need to be put in place.
The rent can be increased between two fixed term tenancies if the tenant and property manager/owner agree.
