Landlord Duty for Smoke and CO Detectors in BC

Utilities & Services British Columbia 3 min read · published March 09, 2026 Flag of British Columbia

Living in a rental in British Columbia means knowing your rights and how safety devices like smoke and carbon monoxide alarms should be handled. Tenants and renters need clear information about who must install, test, and maintain detectors, and when to expect repairs or replacements. This guide explains relevant rules under BC tenancy law and related fire safety standards, shows how to report a non-working alarm, and outlines tenant and landlord duties in plain language. You will also find practical steps to document problems, when to apply for dispute resolution, and links to official BC sources and forms so you can act confidently and protect yourself and your household.

Understanding the rules in British Columbia

Landlords in BC are generally responsible for ensuring a rental unit meets basic safety and habitability standards, including working smoke alarms and, where required, carbon monoxide alarms. The Residential Tenancy Branch provides guidance for tenants and landlords on these duties [1], and the province's Residential Tenancy Act sets the legal framework for remedies and dispute resolution [2]. Fire safety codes and Office of the Fire Commissioner guidance explain technical requirements for alarm placement and testing [4].

Common landlord duties for alarms

  • Safety: install and maintain working smoke and carbon monoxide alarms where required by code or tenancy rules.
  • Maintenance: replace batteries, test alarms regularly, and keep a record of checks and any service.
  • Repairs: respond to tenant repair requests for faulty alarms and arrange prompt fixes or replacements.
  • Entry: provide notice before entering to inspect, replace, or test alarms unless there is an emergency.
Working smoke and carbon monoxide alarms greatly reduce the risk of injury and death in home fires and CO incidents.

What to do if an alarm is missing or not working

If an alarm is missing, non-functional, or you suspect it is incorrectly installed, start by telling your landlord in writing and keep a copy of that message. If the landlord does not act, you can apply for dispute resolution through the Residential Tenancy Branch and ask for an order requiring repair or replacement. See the official guidance on how to apply and what evidence to bring [3].

When documenting the issue, include dates, photos, and any communications with the landlord. For general safety guidance and upkeep expectations while renting, see Health and Safety Issues Every Tenant Should Know When Renting and review local tenancy rights at Tenant Rights and Landlord Rights in British Columbia.

Keep dated photos and a short log of alarm checks to support any complaint or application.
