Where tenants manage IAQ, owner or landlords should be aware of operations and maintenance practices within tenant spaces to check that tenant practices are not negatively impacting adjacent or base building components that are the owner or landlord’s responsibility. 

Inadequate ventilation is one of the major sources of IAQ complaints and also an indicator that the HVAC system may not be functioning optimally. Odourous or dusty operations in tenant spaces have the potential to impact adjacent tenants if the contaminants are not properly controlled. The owner or landlord should ensure any high-risk tenants are diligent with their processes so adjacent tenants are not adversely impacted.
