How does the law define Common Parts regarding mechanical equipment?

The full explanation

Mechanical systems that serve the building's infrastructure are legally protected as Common Parts. This category includes elevators, water tanks, pipes, and generators. It also encompasses chimneys, ventilation fans, ducts, air compressor units, and entire mechanical ventilation systems. These components are essential for the building's habitability and safety. Because they serve the property collectively, their maintenance and repair costs are typically covered by the Service Charges paid by all owners, and they are managed by the building's appointed Management Entity.
