Living in a rental property in Alberta comes with its set of challenges, including the possibility of facing mold and infestation problems. These issues, beyond being a nuisance, can pose significant health and safety risks to tenants. Understanding how to address mold and infestations is crucial for maintaining a healthy living environment.

Understanding Your Rights as a Tenant

In Alberta, tenants are protected under the Residential Tenancies Act when it comes to habitability issues such as mold and infestations. Landlords are responsible for ensuring that rental properties are safe and livable.

Recognizing Signs of Mold and Infestations

  • Mold: Look for spots or discolored patches on walls, ceilings, or floors, and be alert to musty smells.
  • Infestations: Notice unusual droppings, chewed structures, or nests that may indicate pests like rodents or insects.

Steps to Take When You Discover Mold or Infestations

Upon identifying signs of mold or pest infestations, take the following steps to ensure your safety and compliance with legal procedures in Alberta:

1. Notify Your Landlord

Contact your landlord immediately in writing to inform them about the issue. It’s important to keep a record of all communications, including emails or written letters, describing the mold or infestation and requesting timely remediation.

When you notify your landlord in writing, summarize the issue and requested remedy, and keep copies of the message and any landlord replies. If there’s no timely response, continue documenting the situation and consider next steps like inspection or RTDRS.

2. Explore Professional Inspection

If your landlord is unresponsive, consider arranging for a professional inspection of the property. This can help identify the severity of the issue and provide documentation if further legal action is necessary.

If the landlord won’t engage, arrange a licensed inspector and obtain a written report. Use the findings to back up repair requests and any needed formal actions.

4. Leverage Tenant Rights for Stubborn Cases

If the issue persists, tenants can apply to the Residential Tenancy Dispute Resolution Service (RTDRS) for assistance in resolving the matter. The RTDRS handles disputes and can enforce repairs if warranted.

If issues persist, you can seek a ruling from RTDRS; gather the incident report, photos, communications, and any safety concerns to support your case and plan your next steps.

Mold and pest infestations can lead to serious health concerns, so it's essential to be proactive in addressing them. Learn more about potential health risks and precautions at the Health and Safety Issues Every Tenant Should Know When Renting.
