Smoke and CO Alarm Laws for New Brunswick Renters

Safety & Security New Brunswick 4 min read · published March 09, 2026 Flag of New Brunswick

If you are a tenant in New Brunswick, understanding the laws around smoke and carbon monoxide (CO) alarms is crucial for your safety and peace of mind. Both provincial law and local regulations require landlords and tenants to work together to minimize fire and carbon monoxide risks. This guide covers everything you need to know about alarms in New Brunswick rentals, including what’s required, who is responsible, and what to do if there’s a problem.

Why Smoke and Carbon Monoxide Alarms Are Required in Rentals

New Brunswick’s building and fire safety codes mandate that all residential rental properties must be equipped with working smoke alarms. Many units, depending on their fuel sources or attached garages, must also have carbon monoxide alarms. These devices are life-saving tools that offer early warning in the event of fire or unsafe carbon monoxide levels.

What Are Landlords’ and Tenants’ Legal Responsibilities?

Both landlords and tenants share responsibility for keeping alarms in proper working order.

  • Landlord responsibilities: Landlords must install and maintain all required smoke and CO alarms in compliance with the Residential Tenancies Act (New Brunswick), the New Brunswick Building Code, and the Fire Prevention Act1.
  • Tenant responsibilities: Tenants must not tamper with, disable, or remove alarms. They must inform the landlord promptly if an alarm does not work or if maintenance is needed.

These obligations are explained under provincial tenancy law, and failing to comply can result in penalties for either party. For a fuller overview of these shared duties, review Obligations of Landlords and Tenants: Rights and Responsibilities Explained.

Alarm Requirements in New Brunswick Rentals

Here’s what the law requires for rental properties:

  • Smoke alarms: At least one working smoke alarm must be installed on every level of the dwelling, including outside sleeping areas.
  • Carbon monoxide alarms: Required in any unit with a fuel-burning appliance or attached garage. CO alarms should be installed outside all sleeping areas.
  • All alarms must be tested regularly by the landlord, and batteries (in battery-powered alarms) must be replaced on a schedule. Tenants should also test alarms every month.
Regularly check your alarms to ensure they are functioning. Report any malfunction or low battery beeps to your landlord immediately.

What to Do If There Is a Safety Issue

If you discover an alarm is missing, broken, or disabled, notify your landlord in writing as soon as possible. If the problem isn’t fixed promptly, you may contact the Residential Tenancies Tribunal of New Brunswick for further action. Unsafe living conditions due to missing or faulty alarms could qualify as a health and safety violation under the law.

Keep a written record of all alarm issues, dates you notified your landlord, and any responses. If you don’t see timely repairs, contact the tribunal with copies of your notices to seek remediation.

Official Forms and Process for Reporting Safety Issues

If your landlord does not address alarm concerns after being notified, you can file a formal complaint:

  • Form Name: Application for Assistance (Residential Tenancies Tribunal NB)
  • When to use: If the landlord fails to maintain smoke or CO alarms after you have provided written notice.
  • How to use: Complete and submit the form to the Residential Tenancies Tribunal, outlining the specific health and safety issue.
  • Download the Application for Assistance (official PDF)

Once the form is submitted, the tribunal may investigate and issue orders for repairs or compliance if necessary.

The tribunal can issue orders and set deadlines, but resolution timing varies by case and caseload.

Where to Get Help Ensuring Your Rights

For any uncertainty about your rights or if you suspect your rental is unsafe, reach out to the Residential Tenancies Tribunal or seek support from local tenant advocacy organizations. These agencies can guide you through your options and help you take formal action if needed.

If you can’t access online resources, local tenant groups often offer free guidance and can help you prepare documentation for a tribunal filing.
