The rules depend on whether you have a residential tenancy or a licence, rather than simply on the property being described as co-living. If you have exclusive use of your room and share facilities, you may still have tenancy protections, including rules on the timing, notice and amount of a rent increase. A rent-a-room arrangement or some licence agreements can be treated differently, so check your contract and the RTB’s current guidance. If the arrangement is unclear, consider getting advice from a qualified housing solicitor or Threshold; any dispute would ultimately be decided by the RTB based on the facts.
