Who is responsible for pest elimination if infestation in a multiple occupancy building is caused by a failure of an occupant?

In a multiple occupancy building, the responsibility for pest elimination in the case of an infestation caused by the failure of an occupant is shared between both the occupant and the owner. This shared responsibility arises because the occupant is accountable for maintaining their individual unit and is expected to take reasonable measures to prevent pest infestations. However, the owner also has an obligation to ensure the overall health and safety of all tenants living in the building, which includes addressing pest control concerns that could affect the common areas or other units.

A shared approach to pest management recognizes that while an infestation may originate from a specific unit due to an occupant's negligence, it can quickly escalate, impacting neighboring units and the entire building. Thus, the owner may need to take action to manage the situation comprehensively, involving their maintenance staff or pest control services when necessary.

This collaborative responsibility reflects the principles outlined in the International Property Maintenance Code, which aims to establish safe and healthy living conditions in multi-residential settings.
