Mold and pest infestations can significantly impact the health and safety of your living environment, making it crucial to understand your rights as a tenant in Alberta. Addressing these issues promptly is vital for maintaining a healthy home.

Understanding Your Rights as a Tenant

In Alberta, tenants are entitled to a habitable living environment. This means landlords must ensure rental properties are safe and free from issues like mold and pest infestations, as mandated by the Residential Tenancies Act1. If you encounter mold or pests, it's essential to know your legal rights and the steps you can take.

Mold Problems in Rentals

Mold can pose serious health risks and should be handled immediately. If you discover mold, notify your landlord in writing as soon as possible. They are obligated to take reasonable steps to eliminate the issue.

Pest Infestations and Tenant Rights

Pest infestations, such as rodents or insects, need immediate attention. Alberta's laws require landlords to address infestations, provided they arise from natural causes and not the tenant's negligence.

Steps to Take If You Find Mold or Pests

  • Document the Issue: Take photos and keep records of any communications with your landlord.
  • Notify Your Landlord: Provide written notice and allow them a reasonable opportunity to address the issue.
  • Follow Up: If the problem isn’t resolved, you may need to escalate it by filing a complaint with authorities.

Additionally, familiarize yourself with Health and Safety Issues Every Tenant Should Know When Renting.

Tip: Always conduct a thorough inspection when moving in. Document discoveries in a formal checklist to avoid disputes later on.
Create a moving-in inspection form and take dated photos of every room. Keep copies of the form and receipts and share them with your landlord to prevent disputes later.

Escalating Unresolved Issues

If your landlord fails to act, you may need to turn to official channels such as the Residential Tenancy Dispute Resolution Service (RTDRS) for mediation or dispute resolution.2

Do not withhold rent to compel repairs; it can lead to eviction and complicate your case. Instead, document everything and pursue formal remedies.
