Smoke Alarm and CO Check Entry Rules in Alberta

Landlords sometimes need to enter rental units to test or inspect smoke alarms and carbon monoxide (CO) detectors. As a tenant or renter in Alberta you have rights about when and how a landlord may enter, what notice they must give, and how to document checks so your safety and privacy are protected. This guide explains common situations for alarm and CO checks, what landlords are expected to do, which official forms can be used if rules are broken, and practical steps tenants can take to stay safe and keep clear records in Alberta.

What the law says about landlord entry for smoke alarm and CO checks

In Alberta, residential tenancy rules require landlords to provide written notice and a lawful reason for entry; the provincial Residential Tenancies information page explains basic notice and entry expectations for tenants and landlords^[1]. For alarm checks the usual practice is written notice with the purpose stated and a reasonable time for entry. If a landlord enters without proper notice or outside permitted times you can document the event and seek help from the dispute resolution service.

When a landlord can enter for smoke alarm and CO checks

• Entry for scheduled safety checks of smoke alarms and carbon monoxide detectors.
• Entry when the tenant gives clear written consent for a safety inspection.
• Entry for an immediate safety emergency, such as a suspected CO leak or active fire risk.
• Entry ordered by the Residential Tenancy Dispute Resolution Service (RTDRS) or a court.

What tenants can do if a landlord does not follow the rules

• Ask the landlord in writing to provide a proper written entry notice that states the reason and the proposed time.
• Record any refusal or unauthorized entry with dates, times, photos and witness names.
• Contact the landlord to try to resolve schedule or safety concerns before escalating.
• Apply to the RTDRS if there is repeated unlawful entry or a safety risk that the landlord will not address^[2].

Required devices and landlord responsibilities

Alberta guidance explains smoke alarm placement and maintenance expectations, and when carbon monoxide alarms are required in homes with fuel-burning appliances or attached garages^[3][4]. Landlords must supply and maintain required detectors unless the tenancy agreement says the tenant is responsible for a specific device. Tenants should confirm working alarms at move-in, report non-working devices in writing, and keep copies of communications.

Forms and how to file

If a landlord repeatedly enters improperly or ignores a safety issue, tenants can file an application with the RTDRS. Useful official pages and forms include the provincial information on residential tenancies and the RTDRS application and forms page where you can find the Application for Dispute Resolution and filing instructions^[1][2]. Example: if a landlord enters without notice to test an alarm several times and will not stop after a written request, gather copies of notices, written requests, photos and a log, then submit an RTDRS application attaching that evidence.
