Minnesota Carbon Monoxide and Smoke Detector Laws for Renters

Understanding your rights as a renter in Minnesota includes knowing about vital health and safety rules like carbon monoxide and smoke detector requirements. These laws protect renters from serious hazards and outline what landlords must legally provide and maintain in your rental home.

What Are the Minnesota Laws on Smoke and Carbon Monoxide Detectors?

Minnesota law requires smoke detectors in all residential rental properties. Carbon monoxide (CO) detectors are also required in most dwellings, especially if there's any type of fuel-burning appliance (like a gas heater, fireplace, or attached garage).

By law, property owners (landlords) are responsible for providing and installing detectors and ensuring they work at move-in.

Key Landlord Responsibilities

  • Install smoke and CO detectors as required by law for each rental unit.
  • Ensure detectors are working properly at the time a new tenant moves in.
  • Provide written notice to tenants about detector maintenance and placement.

Renters usually must replace batteries (where applicable) and inform the landlord if any detector is not working.

Where Should Detectors Be Installed?

  • Smoke detectors: On every level of the unit, including the basement and each sleeping area.
  • CO detectors: Within 10 feet of every room used for sleeping. Required if the building has a fuel-burning appliance or attached garage.

For a detailed explanation of installation, see the CO Alarm Q&A from the Minnesota State Fire Marshal.

What If Your Detector Is Missing or Broken?

If a required detector is missing, not working, or faulty, notify your landlord in writing as soon as possible. Minnesota law gives tenants the right to a safe and habitable home.

  • Request prompt repair or replacement using clear communication (keep a copy for your records).
It's best to use written forms or emails to document your repair request, in case further action is needed.

Official Repair Request Form

  • Form Name: Tenant's Repair Request (no official statewide form, but always use written documentation)
  • How & When Used: When requesting that your landlord fix or replace a smoke or CO detector. Include your name, address, description of the issue, and the date. Send or deliver this to your landlord and keep a copy.
  • Download Sample Template: The Minnesota Attorney General offers a sample repair request template (see pg. 36).

If the Landlord Does Not Respond

If the landlord doesn't act after your written request, you can bring a Rent Escrow action in Minnesota court. This lets you deposit rent with the court until repairs are made. This process is explained by the Minnesota Judicial Branch's official housing help page.

  • Form Name: Affidavit of Rent Escrow (Form HOU102)
  • How & When Used: Use after reasonable notice to your landlord if repairs aren't made. Complete the Affidavit and file it with your local District Court. You will deposit your rent with the court until the issue is resolved.
  • Official Form and Instructions: Minnesota Judicial Branch Rent Escrow Forms and Instructions

If you have questions about your rental rights under Minnesota law, you can contact the tribunal that handles residential tenancy disputes: Minnesota Judicial Branch (District Court Housing Court).
