Working smoke alarms and carbon monoxide (CO) alarms are your first, and many times, your only life saving defense against fires and CO poisoning. In 2014, almost one-quarter of residential fire victims had no working smoke alarms to warn them. In 12% of these fires, smoke alarms were present but failed to operate.
Massachusetts law requires working smoke and CO alarms in all residences. This page will help you determine the type of alarms you need, where they need to be located, and how to maintain them. Additionally, you may be required to obtain a Certificate of Compliance indicating your home meets these requirements should you wish to sell your home.
