Mould and Indoor Air Quality: Tenant Steps in BC

Trouble with mould or poor indoor air quality in your British Columbia rental can impact both your comfort and your health. As a BC tenant, it's important to know what landlords must do, what you can expect, and how to take effective action if problems aren't fixed. This guide shares essential steps and resources to help you resolve mould and air quality issues, protect your rights, and stay safe in your home.

Why Mould and Indoor Air Quality Matter in BC Rentals

Mould can develop quickly in BC's damp climate, especially during rainy seasons. Left untreated, it may cause respiratory problems, allergies, or aggravate existing health conditions. Poor indoor air quality can also result from inadequate ventilation, water leaks, or improper maintenance.

• Health hazards: Common symptoms include coughing, wheezing, headaches, and skin irritation.
• Damage to property and personal belongings
• Possible decline in rental unit value and living standards

Both landlords and tenants have responsibilities to ensure the property is safe and habitable. For a deeper look, see Health and Safety Issues Every Tenant Should Know When Renting.

Your Rights and Responsibilities in British Columbia

In BC, rental housing health standards are set out in the Residential Tenancy Act and the Public Health Act. Landlords must keep the property in good repair, address water leaks, and resolve conditions that could promote mould. Tenants, in turn, must maintain reasonable cleanliness and promptly report issues.

• Landlords are typically responsible for repairs due to building defects or leaks.
• Tenants are usually responsible for cleaning small, non-structural spots of surface mould resulting from daily living, provided no underlying issue exists.
• Prompt reporting is essential to avoid worsening conditions.

What to Do If You Discover Mould or Poor Air Quality

If you suspect mould, condensation, or persistent musty odours, take these steps:

• Document the problem: Take clear photos and note dates, locations, and any effects on your health or belongings.
• Notify your landlord in writing: Email or a written letter is best. Describe the issue, request repairs, and keep a copy for your records.
• Allow reasonable time for repairs: In BC, a landlord must address issues as soon as possible after being notified.

• If no action is taken and the unit is unhealthy or uninhabitable, you may be eligible for a rent reduction, repairs, or even to end the tenancy early in severe cases.
• Avoid cleaning large mould outbreaks yourself—professional remediation may be needed.

Official Forms for Tenants in BC

• Request for Repairs: While not a specific form, tenants should notify landlords in writing (email or mail) describing the problem and requesting a solution. Keep a copy.
• Application for Dispute Resolution (RTB-12): Use this form if your landlord doesn't act after reasonable notice. Example: You have reported a water leak causing mould, but it remains unrepaired after a week. You may apply for the Residential Tenancy Branch to order repairs, rent reduction, or compensation. Download RTB-12 & instructions.
• Condition Inspection Report (RTB-27): Essential when moving in or out. Documents the state of the property and any pre-existing issues. Get RTB-27 form.

These forms are filed through the Residential Tenancy Branch of British Columbia, the provincial authority handling disputes and tenancy matters.

How to Dispute Unresolved Mould or Air Quality Issues

If your landlord does not act:

• Send a final written reminder outlining the issue, your previous communication, and your request for action.
• Gather proof: photos, correspondence, medical notes (if needed).
• Submit an Application for Dispute Resolution (RTB-12) through the Residential Tenancy Branch. Be clear about what solution you want (e.g., repairs, rent reduction).
• You may be asked for evidence showing that the premises are uninhabitable or hazardous due to mould.

Addressing mould often involves similar steps to dealing with other repair problems. For related advice, see Routine Repairs in Rental Units: Tenant and Landlord Responsibilities.

Prevention and Routine Maintenance Tips

• Use kitchen and bathroom fans when cooking or showering.
• Keep furniture away from exterior walls to allow airflow.
• Report leaks or ventilation failures immediately.
• Open windows regularly to increase fresh air, where weather permits.

Routine vigilance and good communication can help prevent serious problems before they impact your health or tenancy.

FAQ: Mould, Air Quality, and Your Rights

1. Who pays for mould removal in a BC rental? Landlords generally cover costs when mould is caused by structural issues, leaks, or inadequate ventilation. Tenants may be responsible for cleaning mould that results from not ventilating or routine cleaning lapses.
2. Can I withhold rent if my landlord doesn’t fix mould problems? Not without permission from the Residential Tenancy Branch. Withholding rent without authority may risk eviction. Instead, apply for dispute resolution to seek a repair order or rent reduction.
3. Is my rental unit considered unsafe if there is mould? If the mould is widespread, causes health symptoms, or makes the home unfit for living, it may be deemed unsafe. An inspector or tribunal may make the final determination.
4. How do I prove there is a problem with mould or air quality? Use dated photos, written communication with the landlord, maintenance logs, and medical documentation if available.
5. Where can I find more about my rights as a tenant? Visit Tenant Rights in British Columbia for comprehensive information.
