In Brisbane, the responsibility for mould in a rental property depends on the cause and circumstances surrounding its growth. Generally, landlords are responsible for maintaining the property in a safe and habitable condition. This includes ensuring the property is adequately ventilated, free from leaks, and structurally sound to prevent mould growth. If mould develops due to structural issues, leaking pipes, or poor ventilation, it is the landlord’s responsibility to address the root cause and clean the mould.

However, tenants also have a duty to maintain the cleanliness of the property during their tenancy. If mould appears due to a tenant’s lifestyle choices — such as failing to ventilate the home properly, not using exhaust fans, or leaving wet clothes indoors — then the tenant may be held responsible for cleaning the mould and preventing further growth.

Communication is essential. Tenants should promptly notify landlords of any signs of mould or moisture problems. Both parties should work together to resolve the issue quickly to avoid health risks and property damage. In cases of dispute, the Residential Tenancies Authority (RTA) in Queensland can provide guidance and assistance in resolving responsibilities and obligations.
