Who is primarily responsible for ACM control in a building?

The owner is primarily responsible for asbestos-containing materials (ACM) control in a building because they hold the ultimate responsibility for the property and ensuring its compliance with health and safety regulations, particularly those pertaining to hazardous materials. This includes assessing the building for the presence of ACM, managing it appropriately, and ensuring that proper removal or encapsulation occurs if necessary. The owner must also maintain records of any inspections, risks, and abatement activities related to ACM to demonstrate compliance with environmental and safety standards.

While the building manager, contractors, and government agencies play significant roles in the control and management of ACM — with managers often overseeing day-to-day operations, contractors carrying out abatement work, and agencies enforcing regulations — the legal responsibility ultimately lies with the owner. The owner must ensure that any work performed aligns with local, state, and federal regulations regarding asbestos management and that the health and safety of occupants and workers are prioritized.
