This guide explains who is responsible for installing, testing, and replacing alarms, what standards and codes apply in Alberta, and how to raise safety concerns with your landlord or the right provincial authority.

The aim is to keep you and your household safe while protecting your renter rights.

Who is responsible for alarms in Alberta?

In Alberta, landlords are generally responsible for ensuring rental units meet basic safety and habitability requirements, which includes providing functioning smoke and CO alarms at the start of a tenancy under provincial tenancy rules and building/fire codes [1][2]. Tenants are usually expected to test alarms periodically and replace batteries unless the lease states the landlord will do so. If an alarm fails during the tenancy, report it right away in writing and keep a copy of your report.

Report alarm problems in writing and keep a dated copy for your records.

Key Alberta requirements for smoke and CO alarms

  • Install smoke and CO alarms where the Alberta Fire Code or building code requires, typically near sleeping areas and on each level of a dwelling.
  • By law, replace battery-operated alarms or their batteries according to manufacturer guidance and posted timelines to ensure continuous protection.
  • Repair or replace faulty alarms promptly; landlords should arrange repairs within a reasonable time after being notified.
  • Keep records of tests, replacement receipts, and communications about alarms to support any future complaint or dispute.
If alarms are hardwired or interconnected, do not attempt electrical repairs yourself; request a qualified repair from the landlord.

When and how to report missing or non-working alarms

Start by notifying your landlord as soon as you discover a missing or non-working alarm. Make the report in writing (email or letter) so you have a dated record. If the landlord does not act within a reasonable time, follow escalation steps: document the issue, serve a written request for repair, and consider filing an application with the provincial dispute service if necessary [3]. For immediate life-safety problems, call emergency services first.

Practical checks tenants should do

  • Test alarms monthly and after any power outage, and note the date and result.
  • If a removable battery alarm beeps or shows low power, ask the landlord to replace the battery or provide a replacement alarm.
  • Send a clear written notice to your landlord describing the issue, the date you found it, and a reasonable request for repair.
  • Keep copies of all messages and try to resolve the issue through direct communication before filing a formal dispute.
Documenting your steps makes it easier to resolve the problem quickly and to prove your case if a dispute is needed.

FAQ

Who must pay for smoke or CO alarm replacement in a rental?
Unless your lease says otherwise, landlords must ensure alarms are installed and working at the start of tenancy; landlords usually pay for replacements that are not caused by tenant damage. Tenants should replace batteries when specified by the lease or manufacturer and keep receipts.
Can I install my own alarm if one is missing?
You can install a tenant-owned alarm for added safety, but notify the landlord in writing first. Avoid hardwiring or altering building wiring; only qualified personnel should do electrical work.
What if my landlord won’t fix a non-working alarm?
If the landlord does not act after written notice, you can file an application with the provincial dispute service or contact local enforcement for fire code concerns; keep your documentation to support the complaint [3].

How-To

  1. Contact your landlord immediately by phone or email to report the missing or non-working alarm and request a repair or replacement.
  2. Document the problem with photos, the dates you tested the alarm, and any communications with the landlord.
  3. Serve a written notice requesting repair; include the problem, dates, and a reasonable timeframe for action (for example, 72 hours for a critical safety issue).
  4. If the issue is not resolved, file an application with the Residential Tenancy dispute service and attend any hearing with your evidence [3].

Key Takeaways

  • Landlords must provide functioning alarms at the start of tenancy and address safety repairs promptly.
  • Tenants should test alarms, keep records, and report problems in writing.
  • If repairs are not made, documented steps and a dispute application can help enforce your rights.
