Carbon Monoxide Alarms


Massachusetts General Law requires that a Carbon Monoxide Alarms be installed on every level of a home that has fossil fuel burning equipment or an attached garage.

Bedroom Level

The Carbon Monoxide Alarm on the bedroom level of the residence must be within ten feet of all of the bedroom doors. Because of this requirement some homes may require an additional alarm.


Habitable basements, whether finished, partially finished or unfinished must have a Carbon Monoxide Alarm Installed. Alarms are not required in crawl spaces.

Alarm Type

Alarms may be battery operated, plug in, plug in with a battery back up, combination smoke and Carbon Monoxide alarm or hard wired.

Laws & Inspections

The Massachusetts Carbon Monoxide Alarm laws apply to all residences in the state, not just properties being sold.

The Agawam Fire Inspector will check for the presence of Carbon Monoxide Alarms and their proper operation during a Smoke Alarm Inspection and will not issue a certificate if Carbon Monoxide Alarms are not in compliance with the Law.

Detector Age

If your alarm is over 10 years old, it will need to be replaced.
