How to Deal with Mould in Your Rental

Mould in rental properties is a common topic that is raised with Fair Trading.

Landlords are responsible for ensuring that the property is fit for habitation. There are minimum standards which explain what 'fit for habitation' means, including that the property must have adequate ventilation.

​​​​​​​Mould may grow if moisture accumulates in a rental property. Responsibility for this depends on how the mould developed and the specific situation in the property. For example, if mould developed:

• from a build-up of moisture because the landlord failed to repair a broken window in a reasonable time, or the property didn't have adequate ventilation – then the landlord may be responsible and need to fix the problem
• during the tenancy, because the tenants allowed a build-up of moisture by not opening windows or not using ventilation fans in the bathroom – then the tenant may be responsible.

If the property is part of a strata scheme, the owners corporation may also have a role, as they are responsible for matters such as water penetration through external walls or the floor.

Tenants should notify the landlord or agent as soon as possible if they see any signs of mould or damp developing during the tenancy.
