Common Mistakes to Avoid When Reporting Mold to Your Landlord

1. Not Documenting the Mold Growth with Photos
Why it’s problematic: Without visual evidence, it can be difficult to prove the existence and extent of the mold growth, which may lead to disputes or delayed action.
How to fix: Take clear, dated photos of the mold growth, including the area affected and any relevant conditions (e.g., water damage, humidity).
2. Failing to Report Mold Growth in a Timely Manner
Why it’s problematic: Delaying the report can lead to further growth, increased health risks, and potential liability for the tenant.
How to fix: Report mold growth to your landlord as soon as possible, ideally within 24-48 hours of discovery.
3. Not Providing a Clear Description of the Issue
Why it’s problematic: A vague report may not convey the severity of the issue, leading to inadequate or delayed response from the landlord.
How to fix: Include a detailed description of the mold growth, including location, size, and any relevant details (e.g., color, texture, smell).
4. Not Following Up with the Landlord
Why it’s problematic: A single report may not be enough to prompt action; follow-up is essential to ensure the issue is addressed.
How to fix: Schedule a follow-up conversation or send a follow-up email to confirm the landlord has received your report and to inquire about the status of the repairs.
5. Not Keeping Records of Communication
Why it’s problematic: Without a paper trail, it can be difficult to prove that you reported the issue and to track the landlord’s response.
How to fix: Keep a record of all communication with your landlord, including dates, times, and details of conversations or emails.
6. Assuming the Landlord Will Fix the Underlying Cause
Why it’s problematic: If the underlying cause of the mold growth is not addressed, the issue may persist or recur.
How to fix: Ensure that your report specifically requests that the landlord investigate and address the underlying cause of the mold growth (e.g., fix leaks, improve ventilation).
7. Not Being Aware of Your Rights and Responsibilities
Why it’s problematic: Tenants may not know their rights and responsibilities regarding mold growth, which can lead to misunderstandings or inadequate action.
How to fix: Familiarize yourself with the Ontario Residential Tenancies Act and your local bylaws regarding mold growth and landlord responsibilities.
8. Not Escalating the Issue if Necessary
Why it’s problematic: If the landlord does not respond or address the issue, tenants may need to escalate the matter to a higher authority (e.g., local health department, landlord-tenant board).
How to fix: Know when and how to escalate the issue, and be prepared to provide documentation and evidence to support your case.
