What You Need To Know: Massachusetts Smoke Detector Requirements
There can be some confusion about smoke detector regulations in Massachusetts. For instance, the age of your home and the date when it was renovated makes a big difference. There are also things to consider like the type of heating system you have, as well as fuel-burning appliances. The right smoke detector setup can be tricky because there are so many variables at play. In addition to selling hundreds of homes, we have passed many smoke inspections. As a result of our experience, we will be able to guide you through the process and make sure your home is ready to close.
Smoke Detectors
First, let's examine smoke detectors. Smoke detectors should be installed on every level of your house, including the basement and attic (if it's a living space). Hallways aren't the only place where they might be needed - bedrooms might as well. Every bedroom will need one if your home has recently undergone a significant renovation or is being built from scratch. A detector will also need to be installed outside sleeping areas. Detectors should be strategically placed near stairways (base of the stairs) since smoke rises.
Photoelectric and Ionization Smoke Detectors: Choosing The Right Type
Next, you need to choose the right type: photoelectric or ionization. Please don't let the technical names scare you. It is best to use photoelectric smoke detectors in areas close to kitchens and bathrooms. Why would that be? Because they are less likely to emit nuisance alarms when cooking steam or shower steam is present.
Now, in hallways and living areas, ionization smoke detectors can be installed. It is recommended to use only photoelectric devices since they are permitted in all locations of your home. Combination smoke/carbon detectors are available, offering a streamlined solution for meeting safety regulations. Combination smoke/carbon detectors are recommended for efficiency. Keep in mind that if these are used they must have both a tone and simulated voice alarm to distinguish the type of emergency.
Photoelectric vs. Ionization Technologies
In home safety, photoelectric and ionization technologies are used to detect smoke. The differences between the technologies are listed below.
Photoelectric smoke alarms
Detect smoke using light
More effective at detecting smoldering fires, which have been associated with more fatal fires
Only photoelectric detectors are used in household fire warning systems (low voltage or wireless low voltage systems)
Ionization Smoke Detectors
Steam or cooking smoke can cause nuisance alarms
Detect smoke using radiation
It is more effective at detecting flaming fires
Smoke or steam from cooking can cause nuisance alarms
Heat Alarms
Home sellers, even realtors, often forget these regulations and that they must be followed. Any garage attached to or under the residence must have a heat alarm. It must be hardwired and interconnected with or without battery backup to the existing smoke detection system. Garages of older homes are not required to have heat alarms unless they have been renovated, added to, or modified after January 1, 2008.
Hardwired or Battery Operated
For homes built or renovated (permitted) after August 27, 1997, hardwired smoke detectors are required. Directly connected to your home's electrical system, they have a battery backup. There is a huge advantage to this system in that if one alarm goes off, they all go off, offering enhanced safety. In terms of hardwired smoke alarms and carbon monoxide alarms, did you know that they have two different voltage systems? There are some homes that use 24-volt systems, while most use 120-volt systems. The voltage of your smoke detector is usually written somewhere on it. Consult a licensed electrician if you are unsure. Replace your smoke alarms and carbon monoxide alarms with the same voltage when you replace them. It is not recommended to replace a 120-volt smoke detector with a 24-volt smoke detector, or vice versa.
New smoke detectors that are battery-powered must have 10-year, sealed, non-rechargeable, non-replaceable batteries. Smoke detectors and carbon monoxide alarms expire after 10 years. Be sure to check the date of manufacture on each smoke detector. You should replace your smoke detector and carbon monoxide alarm if it has been more than 10 years or if it does not have a date.
It is a requirement that new or replacement alarms come with hush features to prevent nuisance alarms. A hush feature temporarily silences nuisance alarms for a short time, usually several minutes, so you can address the issue. It can be useful if you experience frequent false alarms caused by cooking or other non-emergencies.
In older homes, battery-powered smoke detectors are allowed. Battery-powered or hardwired detectors should be changed annually.
Carbon Monoxide (CO) Alarms: An Added Layer of Safety
Don't forget about carbon monoxide (CO), a silent odorless killer. This is why Massachusetts smoke detector requirements also include carbon monoxide alarms. Your home must have these lifesavers installed on all levels, including the basement. Every level of the residence must have them, including habitable portions of basements and attics, within 10 feet of each bedroom door. Combination smoke and carbon detectors must have both a tone and simulated voice alarm.
Carbon Monoxide Alarm Requirements
All residences with fossil fuel burning equipment or an enclosed attached garage are required to install carbon monoxide alarms since March 31, 2006. Any such residence that is being sold or transferred is subject to this law.
What is Fossil Fuel Burning Equipment?
The term fossil fuel burning equipment refers to any device, apparatus, or appliance that burns fossil fuels, emitting carbon monoxide as a byproduct of combustion. Gas water heaters, oil or gas furnaces, wood or gas fireplaces, wood pellet stoves, gas clothes dryers, or gas cooking stoves are all examples of fossil fuel burning equipment.

Smoke Inspections in Massachusetts: Differences Between Towns and Cities
The requirements for smoke inspections can vary significantly between towns and cities in Massachusetts. A higher population density and increased risk factors often lead to stricter regulations in urban areas, necessitating frequent and thorough inspections. As you prepare your home for the smoke inspection, the Boston smoke and carbon detector reference sheet is a good starting point. In contrast, smaller towns may follow different protocols, ensuring compliance with state mandates while accommodating local resources and infrastructure. Homeowners should be aware of these variations in order to ensure their properties meet all safety standards.
Passing the Inspection: Your Guide to Smooth Sailing
Your realtor can play an important role in helping you pass the smoke inspection. In order to schedule and pass the inspection, you will need the help of a seasoned realtor. Fire departments are often swamped with inspections, so it is important to schedule the inspection as soon as possible. We have seen inspections booked out as far as 3 weeks in advance! A certificate is good for 60 days, so if your closing will take longer, you should consider this. Other times, the schedules are much more relaxed. Knowing which one will be for your home will allow you to act accordingly.
The Smoke Detectors and Passing the Inspection
Upon successful smoke alarm inspection, the local fire department issues a Certificate of Compliance indicating the residence meets smoke alarm requirements. Although the law applies to homes built prior to the date of the building code (Jan. 1975), it is industry practice that most purchase and sales agreements, and many mortgage companies, require the seller to obtain a Certificate of Compliance from the local fire department as a condition of selling or transferring, even if the home was permitted or modified after 1975.
The Carbon Monoxide Detectors and Passing the Inspection
According to Massachusetts General Law, chapter 148 section 26F12 and 527 CMR 1.00:13.7.6, the local fire department must inspect any residence prior to sale or transfer for compliance with carbon monoxide alarms. A Certificate of Compliance indicating compliance with the carbon monoxide alarm requirements will be issued after a successful inspection by the local fire department. An inspection of a smoke alarm and a CO alarm can be conducted at the same time. A failure to meet these requirements could lead to headaches. Selling is always easier and less expensive if everything is handled up front. Ensure a stress-free sale by taking care of these often-overlooked details well in advance.

I admit, I am passionate about helping Massachusetts homeowners sell their homes for top dollar. This passion includes making sure they're prepared and informed every step of the way. Make sure you don't get caught up in the intricacies of Massachusetts smoke detector requirements on your path to selling your property. It is important to address this critical safety step in order to protect yourself but also to ensure a smoother closing process.
