An Act requiring carbon monoxide alarms in all residential, governmental and commercial structures

This bill amends Massachusetts law to require carbon monoxide alarms in all residential, governmental, and commercial buildings, removing a previous limitation that restricted the requirement to "occupied in whole or in part for residential purposes." It expands the existing safety mandate to cover all building types, including offices, stores, and public facilities, not just homes. The key change is eliminating the phrase "occupied in whole or in part for residential purposes" from three sections of the law, ensuring the alarm requirement applies universally. This creates a consistent safety standard for all structures where people live, work, or gather.
