Maintenance & Repairs British Columbia 4 min read · published March 09, 2026 Flag of British Columbia

In British Columbia, living in a rental property should not only be comfortable but also safe for your health and wellbeing. One recurring issue faced by tenants is dealing with mold and infestations. Understanding your rights under the Residential Tenancy Act and learning how the law applies helps you take necessary steps for a healthier living environment.

What is Mold and When Does it Become a Legal Issue?

Mold in rental units typically arises from excess moisture due to leaks, poor ventilation, or condensation. The presence of mold is not only unsightly but can also have serious health impacts. Under the Residential Tenancy Act, landlords in British Columbia are required to provide and maintain rental units in a state that meets health, safety, and housing standards.

Mold issues are often addressed under health and safety standards in housing law. Keep dated notes and photos, and notify your landlord in writing that remediation is needed within a reasonable timeframe; if the landlord doesn't act, you can file a complaint with the RTB or seek mediation to start a resolution process.

If mold stems from a neglect of repairs or maintenance by the landlord, it becomes a legal issue. Tenants should be aware that reporting issues sooner can prevent escalation.

Act quickly: document mold occurrences and notify the landlord in writing to avoid escalation, and keep copies of all communications. If the problem persists, you can contact the RTB for resolution options.

Tenant Rights and Responsibilities

  • Tenants must inform landlords of any mold issues upon discovery.
  • It's essential to ensure your rental unit is adequately ventilated and to mitigate mold growth where possible.

Landlords, on their part, should address the structural causes contributing to mold as a part of their Routine Repairs in Rental Units: Tenant and Landlord Responsibilities.

If you suspect mold is tied to a building defect, request a formal mold assessment or remediation plan from the landlord and ask for a written timeline. You can also contact your local health authority if indoor air quality remains poor.

Infestations: What Tenants in BC Need to Know

Infestations can range from bed bugs to rodents. The presence of pests can render a property uninhabitable, thus breaking the implied warranty of habitability under the Residential Tenancy Act.

Landlords are generally responsible for pest control, but tenants can also play a role in maintaining the cleanliness and regularity of pest mitigation strategies.
