Who is responsible for the maintenance of mechanical systems?

The owner is ultimately responsible for the maintenance of mechanical systems in a building. This responsibility arises from the owner's obligation to ensure that the property meets safety and livability standards. While contractors may install or service these systems, and landlords may have responsibilities outlined by lease agreements, the owner holds the overarching accountability for maintaining systems such as HVAC, plumbing, and electrical.

Regular maintenance is critical for ensuring these systems operate efficiently, safely, and in accordance with building codes. It is the owner's duty to arrange for necessary repairs, comply with local regulations, and ultimately ensure that all mechanical systems are functioning properly. In many jurisdictions, this responsibility cannot be transferred entirely to tenants, as tenants typically are not in a position to manage or oversee the entire mechanical infrastructure of the building. Therefore, it is the owner who must ensure that maintenance protocols are in place and followed, ensuring the well-being of all occupants.
