Black Mould in Rental Properties QLD: Tenant vs. Landlord Risk Responsibility

Mould in Rental Properties QLD

Curious about black mould in rental properties in QLD? Finding black mould in your rental property is stressful. For tenants, there is the immediate fear for your health and your bond. For landlords and property managers, there is the fear of liability and expensive structural damage associated with mould in rental properties QLD.

In Queensland, the rules changed significantly with the introduction of the Minimum Housing Standards (fully effective for all tenancies as of September 2024). The old days of “just spray some bleach on it” are over.

If you are currently staring at a patch of black mould and arguing over who pays the bill, here is the definitive breakdown of responsibility under current QLD law. If you want more tips, check out the AllAces comprehensive mould guide for 2026.

Black Mould in Rental Properties QLD: Structural vs. Lifestyle

Under the Residential Tenancies and Rooming Accommodation Act 2008, the responsibility depends on the source of the moisture. Mould needs moisture to grow. Ideally, an independent inspection determines whether that moisture is coming from the building or the living habits of the tenant. In the former, it is the landlord’s problem, while the latter should be the fault of the tenant. 

Understanding the implications of mould in rental properties QLD is essential for both tenants and landlords.

When is the Landlord Responsible?

Under the new Minimum Housing Standards, a rental property must be “free of damp and mould” when the tenant moves in, and generally kept that way unless the tenant causes it.

The Landlord (Lessor) is responsible if the mould is caused by:

  • Structural Defects: Leaking roofs, rising damp, or cracked walls
  • Plumbing Failures: Burst pipes, leaking flexi-hoses, or slow leaks behind shower tiles.
  • Lack of Ventilation: If a bathroom has no window and no exhaust fan (or a broken one), the mould is likely a structural failure, not a tenant failure.
  • Broken Gutters: Overflowing gutters that dump water into eaves or wall cavities.

In these instances, the landlord must pay for the mould remediation and fix the structural issue. They cannot simply clean the mould without fixing the leak, or it will return.

When is the Tenant Responsible?

Tenants have a duty to keep the property “clean and damage-free.” You may be held responsible if the mould is caused by “Lifestyle Factors.”

The Tenant is likely responsible if the mould is caused by:

  • Inadequate Ventilation: Not opening windows, or failing to turn on exhaust fans during showers.
  • Indoor Drying: Consistently drying wet clothes inside the house without ventilation.
  • Condensation: Allowing condensation to build up on windowsills and walls without wiping it down.
  • Clutter: Stacking boxes or furniture tightly against walls, preventing airflow (common in wardrobes).

In these instances, the tenant is responsible for cleaning the mould and changing their habits. If the mould has penetrated porous materials (like curtains or carpet) due to negligence, the tenant may have to pay for professional replacement.

Mould in Rental Properties QLD: Who Pays for the Inspection?

Disputes often happen when the cause isn’t obvious. The tenant claims the roof is leaking; the landlord claims the tenant never opens a window.

In the standoffs between mould in Rental Properties QLD, assumptions are dangerous. If a landlord ignores a report of mould and it turns out to be a slow pipe leak, they could be liable for:

  • Massive structural repairs.
  • Replacing the tenant’s ruined personal belongings (couches, clothes).
  • Compensation for health impacts.

Conversely, if a tenant drags the landlord to QCAT (Queensland Civil and Administrative Tribunal) and it turns out the mould was caused by their fault, the tenant may lose their bond.

For Landlords:

Act fast. Mould spreads quickly, a small patch today will mean a full wall replacement next month. Also, do not DIY. Paint does not kill mould. Painting over mould is a temporary mask that will peel off and lead to further disputes.
