Maintenance & Repairs Alberta 3 min read · published March 09, 2026 Flag of Alberta

Dealing with mold and infestations can be challenging for tenants in Alberta. Understanding your rights and the responsibilities of your landlord are crucial steps in ensuring a healthy living environment.

Understanding Mold and Infestations

Mold and pest infestations are common issues that affect the safety and comfort of rental homes. Both problems can pose health risks and, if left unaddressed, can lead to more extensive property damage.

Mold in Rentals

Mold often develops in areas with excess moisture, such as bathrooms and basements. If you notice mold in your rental home, it's important to act quickly. Notify your landlord in writing about the issue and request timely repairs.

When you notice mold, document with dated photos and notes about location and size, then send a written repair request to your landlord with a clear deadline. Keep copies for your records.
A good first step for tenants is to document the mold with photos and notes.

Infestations

Infestations from pests such as mice, cockroaches, or bedbugs require immediate attention. Tenants should inform their landlords promptly to initiate proper pest control measures. Knowing your rights can assist in expediting a resolution through official channels.

For infestations, list all affected areas in writing, include dates of sightings, and request a pest-control assessment with a remediation plan and timeframe.

Landlord Responsibilities

Under Alberta's Residential Tenancies Act, landlords must ensure that rental properties are fit for habitation and comply with health standards. This includes addressing mold and pests promptly.

Landlords must maintain habitable premises and address health and safety issues promptly; if mold or pests persist, document with photos and notices and consider dispute resolution options.
  • Mold Remediation: Landlords should fix any leaks or ventilation issues that contribute to mold growth.
  • Pest Control: They should also provide pest control treatments when infestations occur.

Tenant Actions

Tenants can take the following steps if they encounter mold or infestations:

  • Report the issue in writing: Include detailed information and evidence, such as photos.
  • Request repairs: Specify a reasonable deadline for action.
  • Follow up: If the landlord does not respond, consider contacting the Residential Tenancy Dispute Resolution Service (RTDRS) for assistance.
Keeping a written timeline of communications helps if you later pursue formal remedies or RTDRS, especially when deadlines are involved.

Understanding Obligations of Landlords and Tenants is essential when facing maintenance issues.

Filing a Complaint

If your landlord does not address the issue, you can apply to the RTDRS for a resolution. The RTDRS specializes in resolving tenant-landlord disputes, including those related to maintenance and repairs.

Example: assemble your lease, photos, receipts, and a chronology of communications before applying to RTDRS or requesting a hearing.

Tenants should also be aware of their rights and responsibilities concerning health and safety. The guide on Health and Safety Issues Every Tenant Should Know When Renting provides detailed insights.
