Smoke alarms are an essential safety feature for any home. In Minnesota, the law requires the proper installation and maintenance of smoke alarms. Here’s what you should know.
House fires can become dangerous in mere moments. Modern homes and furnishings burn fast, often giving families less than three minutes to escape. Without an early warning system, that time is even shorter, making working smoke alarms one of the most important safety tools in any home.
According to the Minnesota Department of Public Safety, not having a working smoke alarm in your home reduces the chances of surviving a house fire by 50%. According to the National Fire Protection Association, three out of five home fire deaths occur in houses with no smoke alarm.
Fires often ignite while people are asleep, and without an alarm to wake them, the results can be devastating. Despite this, many Minnesota homes lack adequate protection due to missing, non-functional, or improperly placed alarms.
Minnesota state law requires all residential buildings to have properly installed smoke alarms. Compliance with these requirements will not only help you avoid costly fines but may also save lives in a house fire.
For newer homes, state law mandates that smoke alarms must be installed in the following locations:
For homes built on or after March 31, 2020, smoke alarms must be hardwired with a 120-volt power supply and have a battery backup. They must also be interconnected so that they all go off if one alarm goes off. This feature warns the whole home and gives everyone more time to react.
For older homes, the rules vary based on the construction date. To learn more, see the Smoke Alarm Requirements guide provided by the Minnesota State Fire Marshal.
A smoke alarm is only effective when it is installed and used properly. Here are some tips to keep in mind:
If you’re unsure whether your home’s smoke alarms are installed correctly, many local fire departments in Minnesota offer free home safety checks and installation assistance. The Red Cross also provides this service through the Minnesota-Dakotas Home Fire Campaign.
A smoke alarm isn’t enough – you need to ensure it works. Test each alarm at least once a month by pressing the test button. Check the battery or replace the unit if the alarm doesn't sound.
Batteries should be replaced at least once a year, though some newer models come with sealed, 10-year batteries that never need changing. Regardless of battery type, the smoke alarm should be replaced every 10 years as sensors degrade over time.
If your smoke alarm begins to chirp intermittently, it’s warning you that the battery is low. Don’t ignore this signal – replace the battery immediately. A non-functioning smoke alarm is just as dangerous as not having one at all.
Not all smoke alarms are created equal. Some models offer additional features that enhance protection, especially for larger homes or households with young children, elderly residents, or individuals with disabilities.
Hardwired smoke alarms are connected directly to a home’s electrical system and come with a backup battery. These provide a more reliable option than battery-operated alarms, which continue working even if the battery dies.
For added safety, consider installing interconnected smoke alarms even if they aren’t required by law for your home. Smart smoke alarms take this safety feature even further by sending real-time alerts to your phone, ensuring you’re notified even when you’re away.
For individuals who are deaf or hard of hearing, specialized smoke alarms with strobe lights and bed-shaking features provide essential early warnings. Many Minnesota fire departments offer these alarms for free to eligible residents.
If you don’t have smoke alarms or need replacements, several Minnesota organizations provide free smoke alarms and installation assistance.
The American Red Cross offers free smoke alarms to Minnesota households and personalized fire safety education. Residents can request an installation appointment through the Red Cross website.
In Saint Paul, Project Safe Haven provides free smoke alarms, carbon monoxide detectors, and StoveTop Fire Stops to qualifying homeowners. More details can be found on the City of Saint Paul’s website.
Many local fire departments across the state partner with organizations to distribute free smoke alarms and conduct home safety inspections. Contact your local fire station to see if assistance is available.
A working smoke alarm isn’t just a recommendation. It’s a necessity. Fires can happen to anyone at any time, and having a properly installed and functioning smoke alarm drastically increases the chances of survival.
If you haven’t tested your smoke alarms recently, do it today. If they aren’t working, replace them immediately. If you don’t have enough smoke alarms in your home, take advantage of Minnesota’s free smoke alarm programs before it’s too late.

Minnesota law mandates that all residential buildings have properly installed smoke alarms. For homes built on or after March 31, 2020, smoke alarms must be hardwired with a 120-volt power supply, include battery backup, and be interconnected so that if one alarm activates, all do. Specific placement includes inside every bedroom, outside each sleeping area, and on every level of the home, including basements and habitable attics.
Test each smoke alarm monthly by pressing the test button. Replace batteries at least once a year, or consider models with sealed, 10-year batteries. Regardless of battery type, replace the entire smoke alarm unit every 10 years, as sensors can degrade over time.
An intermittent chirping sound typically indicates a low battery. Replace the battery immediately to ensure the alarm functions correctly. If the chirping continues after battery replacement, the unit may be faulty and should be replaced.
In Minnesota, landlords are responsible for installing and maintaining functional smoke alarms in rental units. However, tenants must regularly test the alarms and replace batteries as needed. If a landlord fails to provide working smoke alarms, they may be liable for any injuries or fatalities resulting from a fire.
Homes built on or after August 1, 1989, must have hardwired (120-volt) smoke alarms. Battery-powered alarms are acceptable for homes constructed before this date, and interconnected alarms are not required.
No, you should never disable a smoke alarm while cooking. Instead, to prevent false alarms, ensure the alarm is installed at least 10 feet away from cooking appliances. If a false alarm occurs, open a window or door, press the hush button if available, or wave a towel near the alarm to clear the air.
Frequent false alarms may indicate the need for maintenance or replacement. Ensure the alarm is clean and free from dust or insects, which can trigger false alarms. If the problem persists, consider replacing the unit, especially if it's nearing the end of its 10-year lifespan.
