Minnesota smoke and carbon monoxide alarm rules: owner duties, a 24-hour tenant report and a first-violation warning
Minnesota splits the rules in two statutes. Under 299F.362 the owner maintains smoke alarms in rented units, and the occupant must tell the owner within 24 hours of finding one not working. Under 299F.51 a multifamily owner installs a carbon monoxide alarm within ten feet of each sleeping room, and a first violation brings a warning, not a penalty.
What does 299F.362 require for smoke alarms?
Every dwelling unit in a dwelling must have a smoke alarm that meets the State Fire Code and sounds an alarm within that unit when activated. Apartment units and sleeping guest rooms in lodging houses and hotels have the same requirement. New dwellings must connect alarms to a centralized power source. The Commissioner of Public Safety sets placement rules, and alarms must be mounted according to them.
When the occupant is not the owner, the owner is responsible for maintaining the alarms, and the owner may file inspection and maintenance reports with the local fire marshal as evidence. Occupants must tell the owner about a nonfunctioning alarm within 24 hours of discovering it; if they do not, their liability for damages is no greater than it otherwise would be. An occupant who willfully disables an alarm, causing damage or injury, commits a misdemeanor.
What does 299F.51 require for carbon monoxide?
Single-family dwellings and multifamily units need an approved, working CO alarm within ten feet of each room used for sleeping. Hotel and lodging guest rooms need one in each sleeping room. A multifamily owner must install the alarms, and must replace any required alarm that was stolen, removed, missing or disabled during a prior occupancy and not replaced by the prior occupant before a new occupancy begins.
Occupants in multifamily units where the owner installed the alarm keep it in good repair, and replace one stolen, removed, missing or disabled during their occupancy. No one may remove batteries from a required CO alarm or otherwise make it inoperable.
Example a made-up owner in Rochester, Minnesota finds a CO alarm missing after a tenant moves out. Before the next tenant arrives, the owner installs a new approved alarm within ten feet of the bedroom and notes the date.
Are there exceptions and penalties?
- Multifamily dwellings may use detectors placed 15 to 25 feet from central CO-producing fixtures if a centralized alarm system lets responsible parties hear the alarm at all times.
- Owners of multifamily dwellings with minimal or no CO sources may be exempt if they certify to the commissioner of public safety that there is no foreseeable CO risk.
- A first CO violation results in a safety warning and no penalty; a second or later violation is a petty misdemeanor.
- An insurer cannot deny a fire-loss claim because someone failed to comply with the smoke alarm section.
Where Minnesota owners slip
The clock matters on both sides. A tenant's 24-hour report is the trigger for your repair, so make reporting easy: a text number or app request that is monitored daily. Owners also lose time on turnover. The CO statute names the missing or disabled alarm left by a prior occupant, which means the check belongs in your move-out walk-through, not in a promise to fix it later. For multifamily buildings with a central system, keep the certificate or the system record where a fire official can find it. Finally, remember that these two statutes do not say who installs smoke alarms or how often to test; the State Fire Code governs details, so keep the code section handy.
How DoorKeeping fits in Minnesota
DoorKeeping keeps a Minnesota unit's alarm checks as dated work orders with photos, so the move-in test, the tenant's reports and your fixes are on the record. A tenant's report arrives with a timestamp, which is what the 24-hour rule is measured against. This is general information, not legal advice. Check the current statute, your local fire code and your lease before you act.
