Full Breakdown

Massachusetts has some of the strictest residential smoke-alarm laws in the country. Under MGL c.148 s.26F and 527 CMR 1.00, all dwellings must have smoke detectors on every level, inside and outside each sleeping area, and within 20 feet of kitchens. Homes built or substantially renovated after 1975 must have interconnected hardwired alarms with battery backup; older homes may use photoelectric or combination battery alarms, but single-station ionization alarms alone no longer meet code. Carbon monoxide detectors are also required on every level and within 10 feet of every bedroom under MGL c.148 s.26F1/2. Before any residential property is sold or transferred, the seller must obtain a Certificate of Compliance from the Lowell Fire Department confirming alarms meet current code. The inspection is scheduled through the Fire Prevention Bureau and typically costs around 50 dollars. Landlords must verify working detectors at every tenancy change.

Yes. Massachusetts law requires a Certificate of Compliance from the Lowell Fire Department before any residential sale can close.
Are battery-only smoke alarms legal?
