A new change in Massachusetts smoke detector regulations will take effect December 1 2016. The new rules provide that when homes built before 1975 are sold, the house must be equipped with smoke detectors with a 10-year life span. These detectors are sold as 10 year sealed lithium battery power smoke alarms. They can be found at your local Home Depot or hardware store.
Also remember that current rules require photoelectric detectors covering the area within 20 feet of a kitchen or bathroom containing a bathtub or shower. The 10 year sealed detectors are sold with both photoelectric and the older ionization technologies. Please contact us if you have any questions.
