Smoke Detector & Carbon Monoxide Information

Smoke & Carbon Monoxide Detector RequirementsSmoke Detector Image

For ease of use, the informational links are based on when your house was built. However, if the property was renovated with additional bedrooms, added an attached garage or major alterations including gutting, re-configuring bedroom walls, installing hard-wired smoke detectors, etc., choose the link for the time period when the renovation was performed. The year the renovations were performed will supersede the original construction date.

Once smoke detectors are hard-wired they need to remain hard-wired.

Every level of the home must have at least 1 smoke detector and 1 carbon monoxide detector.
Smoke detectors older than 10 years old need to be replaced. 
Carbon Monoxide detectors need to be replaced every 5 to 7 years depending on the manufacturer's instructions. 

On December 1, 2016, the State of Massachusetts updated the smoke detector requirements for residences built prior to 1975.  Most of these residences will have only battery-operated smoke detectors.

Smoke Detector Inspections

A Certificate of Compliance is required for the sale or transfer of a property (M.G.L. c 148 s.26).

As of Monday, June 15, 2020, the Fire Department will start accepting phone calls to schedule appointments for smoke detector inspections.  Fire Department Headquarters is still closed to the public.
