Mold, Pests, and Health Hazards in Alberta Rental Homes

Moving In / Out Alberta published June 12, 2025

Facing mold, pests, or other health hazards can be a stressful experience for Alberta renters. Knowing your rights and the steps you can take to address these issues will help keep your home safe, healthy, and comfortable. This guide provides plain-language advice and references to the specific legal protections available to tenants in Alberta.

Your Right to a Safe and Healthy Rental

In Alberta, landlords must provide and maintain rental properties in a condition that is safe, sanitary, and suitable for occupancy. This includes addressing issues like mold, pest infestations, and hazards to health. These obligations come from the Residential Tenancies Act and the Public Health Act^[1]. Tenants also have a duty to keep the home reasonably clean and report problems quickly.

Common Health Hazards: What Counts?

Mold and Mildew: Growth of mold due to water leaks, flooding, or poor ventilation can cause respiratory problems and allergic reactions.
Pest Infestations: Mice, cockroaches, bed bugs, and other pests can spread disease and make the home uninhabitable.
Other Hazards: Exposed wiring, lack of heat, lead paint, asbestos, or water that’s unsafe to drink.

If these hazards exist and you’ve reported them to your landlord, you have options to ensure your health and safety are protected.

What To Do If You Find Mold or Pests

If you discover mold or a pest problem:

Document the issue: Take clear photos and make notes of where and when you noticed the problem.
Notify your landlord in writing as soon as possible. Email is often best so you have a record.
If the landlord does not act promptly, escalate the issue appropriately (see below).

If your health or safety is in danger, act quickly and keep a written record of all communication with your landlord.

Landlord’s Responsibility

Alberta law requires landlords to handle health hazards like mold and pests as soon as they become aware of them. For details about roles, read Health and Safety Issues Every Tenant Should Know When Renting.

Reporting to Alberta Health Services

If your landlord doesn’t respond to requests for repairs or pest control, you can contact Alberta Health Services Environmental Public Health. An inspector may visit your unit, assess the situation, and order the landlord to fix the problem if needed.

Report a health concern to Alberta Health Services

Remember to stay in touch with your landlord throughout this process and provide every opportunity for them to remedy the issues first.

Filing a Complaint or Seeking Repairs

If the health hazard persists, tenants may apply to the Residential Tenancy Dispute Resolution Service (RTDRS) or the Alberta Courts.

Residential Tenancy Dispute Resolution Service (RTDRS)

The RTDRS hears disputes related to repairs, health and safety obligations, rent, and other major tenancy matters. You can use the RTDRS application form if the landlord fails to address mold, pest infestations, or other hazards.

Relevant Forms and How To Use Them

RTDRS Application (RTDRS 1): Use this form if your landlord has not addressed hazardous conditions in your rental. It is available through the RTDRS website.
Example: You have mold that hasn't been fixed after notifying the landlord—submit the RTDRS application to seek an order requiring repairs. Access the RTDRS Application Form
Public Health Complaint Form: Use this online form to report health hazards directly to Alberta Health Services if urgent action is required. Report a health concern

Moving In or Out with Health Concerns
