Mould in rental properties is no longer just a seasonal inconvenience. It has become one of the fastest-growing legal and financial challenges facing Victorian property managers and rental providers. In recent years, advocacy groups such as Tenants Victoria have reported a steady increase in renters seeking help for mould-related issues, and more cases are now escalating to the Victorian Civil and Administrative Tribunal (VCAT).
With wetter conditions, ageing housing stock and stricter rental standards introduced under the Residential Tenancies Regulations 2021, mould is emerging as a key factor in disputes and compensation claims across the state.
The Growing Mould Problem in Victorian Rentals
Reports from Tenants Victoria and other advocacy bodies show a recurring pattern: mould complaints climb sharply during cooler, damp months when homes retain moisture for longer. Despite the updated minimum rental standards introduced in 2021, many properties still fall short in areas such as ventilation, moisture control, and structural maintenance.
Under current regulations:
- Rental properties must be free from mould and damp caused by the building structure.
- All habitable rooms must have adequate ventilation that meets Building Code of Australia standards.
- Rental providers must disclose any known mould or damp issues from the previous three years.
- If mould is caused by structural faults, including leaks or plumbing failures, the repairs are classified as urgent and must be addressed immediately.
Failure to meet these obligations has contributed directly to the rise in cases heading to VCAT.
When Mould Issues Escalate to VCAT
When tenant repair requests are delayed, dismissed, or handled incorrectly, the likelihood of escalation to VCAT increases significantly. Once a matter reaches the tribunal, rental providers may face:
- Urgent repair orders, requiring immediate action
- Fines or penalties for non-compliance
- Compensation orders for damaged belongings, health impacts or loss of amenity
One of the costliest risks is that most landlord insurance policies exclude mould damage, meaning remediation often becomes an out-of-pocket expense for owners. This places even greater importance on proactive management.
Proactive Management: The Best Defence Against VCAT Claims
Property managers and rental providers who act quickly, communicate clearly and follow best-practice maintenance guidelines are far less likely to face expensive tribunal outcomes. A proactive mould management approach includes:
- Prioritise Communication and Fast Action
Educate tenants about ventilation, proper use of exhaust fans, and early reporting of leaks or dampness. When a report comes through, respond quickly. Small leaks addressed early prevent the large-scale damage that often leads to VCAT involvement.
- Conduct Regular Inspections
Routine inspections, particularly in high-moisture areas such as bathrooms, kitchens, attics and subfloors, help detect early signs of mould, condensation or poor ventilation. Early detection significantly reduces long-term repair costs.
- Strengthen Prevention Across All Properties
Ensure ventilation meets regulatory requirements and that fans vent externally. Consider mould-resistant paints in humid zones and install ground moisture barriers in enclosed subfloors. These preventative upgrades reduce risk and support regulatory compliance.
- Engage Qualified Specialists
Determining the source of mould is critical for understanding responsibility under Victorian rental law. A professional assessment from a specialist like MouldMen provides clarity, documentation and a remediation plan that meets legal standards. This is especially important for recurring issues or disputes in progress.
Partnering with experienced technicians strengthens compliance, protects landlords’ investments and supports tenant health.
