Smoke and carbon monoxide alarms are among the simplest and most effective safety features in any home. In Massachusetts, where many families live in older houses heated through long winters, they are especially important. The state also has specific requirements for alarms, particularly when homes are sold or transferred. This guide explains where alarms should go, how to choose the right types and how to keep them working, so you can protect your household with confidence.

Why Working Alarms Matter
Most fatal home fires happen at night, when people are asleep. Smoke can overcome occupants before they wake, which is why early warning is critical. Working smoke alarms give families precious time to escape. Carbon monoxide, meanwhile, is invisible and odourless, and exposure can cause illness or death. A properly installed and maintained carbon monoxide alarm is the only reliable way to detect it.
Where to Install Smoke Alarms
Install smoke alarms on every level of the home, including basements and finished attics, outside each sleeping area and, as recommended by fire safety experts, inside bedrooms. Mount alarms on ceilings or high on walls following manufacturer instructions, and keep them away from windows, doors and ducts where drafts could interfere. In older homes with additions and multiple stairways, make sure every area is covered.
Alarms placed too close to kitchens and bathrooms can cause nuisance alarms from cooking or steam. Massachusetts rules generally call for photoelectric alarms in these areas, positioned at appropriate distances.
Choosing the Right Types
There are two main types of smoke alarm technology. Ionisation alarms respond quickly to fast, flaming fires, while photoelectric alarms respond quickly to slow, smouldering fires and are less prone to nuisance alarms from cooking. Many fire safety organisations recommend photoelectric alarms or a combination of technologies. When battery powered alarms are replaced in many Massachusetts homes, the rules generally call for long life sealed battery alarms that do not require battery changes.
Interconnected Alarms
Interconnected alarms communicate with each other, so when one detects smoke, all of them sound. This is especially valuable in larger homes or multi level houses where an alarm in the basement might not be heard upstairs. Interconnection can be hard wired or wireless. Renovations are an ideal time to add hard wired interconnected alarms while walls and ceilings are open.
Every alarm in the right place, tested and working, is a quiet promise that your family will have time to get out safely.
Protecting Against Carbon Monoxide
Carbon monoxide is produced by fuel burning appliances such as furnaces, boilers, water heaters, gas stoves, fireplaces and attached garages. Massachusetts requires carbon monoxide alarms in homes with fossil fuel burning equipment or enclosed parking areas, generally on every level of living space. Combination smoke and carbon monoxide alarms can simplify installation. Have heating systems and chimneys inspected annually, keep vents clear of snow in winter and never run generators, grills or vehicles in enclosed spaces.
Massachusetts Inspections at Sale
Before most homes in Massachusetts are sold or transferred, the local fire department must inspect smoke and carbon monoxide alarms and issue a certificate of compliance. Requirements vary depending on when the home was built or last substantially renovated, and local fire departments administer the inspections. If you plan to sell, contact your fire department early and make sure alarms meet current requirements to avoid delays at closing.
Substantial renovations and additions may trigger updated alarm requirements under the building code. Your contractor and building inspector will confirm what applies to your project.
Testing and Maintenance
Test every alarm monthly by pressing the test button. Replace batteries in alarms that use replaceable batteries according to the manufacturer's instructions, and replace alarms themselves when they reach the end of their service life, which is printed on the alarm. Gently vacuum alarms to remove dust and cobwebs. Never disable an alarm because of nuisance alerts; instead, relocate it or replace it with a more suitable type.
Plan and Practise Your Escape
Alarms only help if everyone knows what to do when they sound. Create a home escape plan with two ways out of every room where possible, choose a meeting place outside and practise the plan with everyone in the household, including children and older relatives. In winter, keep exits and paths clear of snow and ice, and make sure windows used for escape open easily.
Other Fire Safety Upgrades
Alarms work best as part of a broader approach. Keep a fire extinguisher in the kitchen and learn how to use it. Have older electrical systems evaluated, especially if you have knob and tube wiring, fuse boxes or frequently tripping breakers. Use space heaters carefully, keep combustibles away from heat sources and have fireplaces and wood stoves cleaned and inspected regularly.
Protecting Every Member of the Household
Consider the needs of everyone in your home. Alarms with strobe lights and bed shakers help people who are deaf or hard of hearing. Children may sleep through alarms, so practise waking them during drills and assign an adult to help. Older relatives may need assistance or a bedroom closer to an exit.
Smart Alarms and Monitoring
Smart smoke and carbon monoxide alarms send alerts to your phone when they sound, which is helpful when you are away from home or have family members who live alone. Some systems can be professionally monitored so emergency services are contacted automatically. Smart alarms can also announce the location and type of danger and send reminders when batteries are low or alarms need replacing. Make sure any smart alarm you choose is listed by a recognised testing laboratory and meets Massachusetts requirements.
Fire Safety for Multi Family Homes
Many homes in Newton and nearby communities are two family houses or have accessory apartments. Each unit needs its own working alarms, and common hallways, stairways and basements need coverage too. Owners of rental units have additional responsibilities under state law and the sanitary code, including maintaining alarms in working order. Clear communication between owners and tenants helps everyone stay safe.
