Understanding Mould Responsibility in QLD Rental Properties
Mould in a rental property is one of the most common sources of disputes between tenants and landlords in Queensland. Brisbane's subtropical climate, with high humidity and warm temperatures year-round, creates ideal conditions for mould growth. Understanding who is responsible for dealing with mould is critical for both parties.
Landlord Obligations Under QLD Law
Under the Residential Tenancies and Rooming Accommodation Act 2008, landlords are required to maintain rental properties in good repair and in a condition that is fit for the tenant to live in. This includes ensuring the property is structurally sound, free from leaks, and adequately ventilated. When mould is caused by a building defect such as a leaking roof, rising damp, faulty plumbing, or inadequate exhaust fans, the landlord is responsible for both fixing the root cause and arranging professional mould removal.
Tenant Obligations
Tenants have a duty to keep the rental property reasonably clean and to report maintenance issues promptly. If mould develops due to lifestyle factors such as not using exhaust fans during showers, drying clothes indoors without adequate ventilation, or blocking air vents, the tenant may be held responsible. Crucially, tenants must report mould as soon as they notice it. Failure to report can shift partial responsibility to the tenant, even if the underlying cause is a building issue.
When Responsibility Is Shared
In many cases, mould in a rental property is the result of both structural issues and tenant behaviour. For example, a bathroom with an inadequate exhaust fan combined with extended hot showers may lead to mould that neither party can be solely blamed for. In these situations, a professional mould inspection can identify the contributing factors objectively and help both parties reach a fair resolution.
What to Do If You Cannot Agree
If the tenant and landlord cannot agree on who is responsible for mould, either party can apply to the Residential Tenancies Authority (RTA) for dispute resolution. A professional mould inspection report is often the most effective evidence in these disputes, providing an independent assessment of the mould's cause and severity.
