"This adds another layer of protection in situations of sub-leasing, which is becoming much easier for tenants to do," Gunatunga said.
The tribunal found the landlord could recover the profits from the subleasing activity after Gunatunga sought an "account of profits" by demonstrating it was unreasonable to allow the tenant to profit from a breach of the tenancy agreement.
The tenant's action was the worst breach of the Tenancy Agreement that Nice Place Property Management company director Keith Powell said he had seen after 13 years in the business.
Powell took over management of the apartment property after the property owner suspected his apartment was being sub-leased.
Upon discovering that the suspicion was correct, Powell contacted the tenant to address the breach.
The tenant stopped rent payments, installed a dead bolt and left.
"It's unusual to see the Tenancy Agreement explicitly state that sub-leasing on Airbnb is prohibited," Powell said.
In addition to the profits from subleasing the apartment on Airbnb, the tenant was also ordered to pay unpaid rent, exemplary damages for abandonment, subleasing and replacing locks, as well as costs for door replacement.
