Mould in Rental Property VIC: Your Rights as a Tenant

Mould in a rental property is a serious issue that affects thousands of Victorian tenants. The Residential Tenancies Act 1997 (VIC) sets out clear obligations for landlords and rights for tenants. Understanding these rules helps you take effective action. We connect you with qualified mould specialists for assessments and remediation.

Landlord Obligations Under Victorian Law

The Residential Tenancies Act 1997 (VIC) places clear obligations on landlords regarding property maintenance and habitability.

Fit for Habitation

Landlords must ensure the property is maintained in a condition fit for habitation. Significant mould growth that affects health or livability breaches this obligation. This applies from the start of the tenancy and throughout its duration.

Good Repair

The landlord must maintain the property in good repair. This includes fixing structural issues that cause mould — such as leaking roofs, broken plumbing, faulty waterproofing, inadequate ventilation, and rising damp.

Respond to Repair Requests

When a tenant reports mould or the conditions causing it, the landlord must arrange repairs within a reasonable timeframe. For urgent repairs (property unsafe or insecure), the response must be prompt — typically within 24-48 hours.

Structural Causes

If mould is caused by structural issues — leaking pipes, poor ventilation design, rising damp, lack of insulation, or failed waterproofing — the landlord is responsible. These are not tenant-caused issues and the landlord must remediate at their expense.

Minimum Standards

Since March 2021, Victorian rental minimum standards include requirements for ventilation, structural soundness, and weatherproofing. Properties that fail these standards may be contributing to mould growth and the landlord must bring them into compliance.

Professional Remediation

For significant mould, landlords should engage qualified professionals — not just ask tenants to clean it. Surface cleaning without addressing the cause means mould returns. Professional assessment and remediation is the appropriate response.

Tenant Responsibilities

While landlords bear primary responsibility for structural causes of mould, tenants also have obligations under the Residential Tenancies Act 1997. Understanding your responsibilities strengthens your position if a dispute arises.

Tenants must keep the property reasonably clean and not intentionally or negligently cause damage. This means using exhaust fans when cooking and showering, not blocking ventilation openings, drying clothes outdoors or in well-ventilated areas, and reporting moisture issues promptly.

Importantly, tenants are not responsible for mould caused by structural defects, even if the landlord claims it is a “lifestyle” issue. If the property lacks adequate ventilation, insulation, or has unrepaired leaks, these are landlord responsibilities regardless of tenant behaviour.

Your Obligations as a Tenant

✓Use exhaust fans when cooking and showering
✓Don't block or cover ventilation openings
✓Dry clothes outdoors or in ventilated areas when possible
✓Open windows periodically for air circulation
✓Report mould and moisture issues to the landlord promptly
✓Report leaks, drips, and plumbing issues immediately
✓Keep the property reasonably clean
✓Don't cause damage that leads to moisture ingress

How to Report Mould & Escalate If Needed

Document Everything

Photograph all mould and moisture damage. Note dates, locations, and extent. Record any health symptoms. Keep a timeline of when issues appeared and worsened. This evidence is crucial for any dispute.

Report in Writing

Notify your landlord or property manager in writing (email creates a timestamped record). Describe the mould, its location, suspected cause, and any health impacts. Request repairs within a specific timeframe (14 days for non-urgent, immediate for urgent).

Follow Up

If the landlord doesn't respond or the repairs are inadequate, send a follow-up notice. Reference the Residential Tenancies Act and your right to apply to VCAT. Keep records of all correspondence and any repair attempts.

Apply to VCAT

If the landlord fails to act, apply to the Victorian Civil and Administrative Tribunal (VCAT). VCAT can order repairs, rent reduction, and compensation. Application fees are approximately $65 for tenants. Consider contacting Tenants Victoria for advice first.

Urgent Repairs & Emergency Provisions

The Residential Tenancies Act 1997 includes provisions for urgent repairs. If the property is unsafe or insecure, or if an essential service is not working, the repair is classified as urgent.

Severe mould that poses an immediate health risk— particularly where children, elderly, or immunocompromised people reside — may qualify as urgent. A burst pipe causing flooding and subsequent mould is clearly urgent.

For urgent repairs, tenants should contact the landlord or agent immediately. If the landlord cannot be contacted or fails to arrange repairs, the tenant may arrange repairs up to $2,500 and seek reimbursement from the landlord. Get receipts and document the urgency thoroughly.

Why a Professional Mould Assessment Matters for Rental Disputes

A professional mould inspection report is your strongest evidence in a rental dispute. It identifies the mould type, extent, and — critically — the moisture source causing it.

Independent Evidence

A report from a qualified, independent mould inspector provides objective evidence that strengthens your position at VCAT. It documents what the landlord claims is a "lifestyle issue" as a structural problem.

Identifies the Cause

Professional inspectors identify whether mould is caused by structural issues (landlord's responsibility) or tenant behaviour. This distinction is crucial for determining liability.

Scope of Remediation

The report outlines what remediation work is needed, helping VCAT understand the appropriate response. It also gives the landlord clear guidance on what needs to be done.

Rental Mould FAQs — Victoria

Under the Residential Tenancies Act 1997 (VIC), landlords must maintain rental properties in good repair and fit for habitation. If mould is caused by structural issues (leaks, rising damp, poor ventilation, lack of insulation) the landlord is generally responsible for both the cause and remediation. If mould is caused solely by the tenant's lifestyle (not using exhaust fans, blocking vents, excessive indoor drying), the tenant may be responsible.

Report mould to your landlord or property manager in writing (email is ideal for creating a record). Include photos, describe the location and extent, note any health impacts, and request repairs within a reasonable timeframe. Under the Residential Tenancies Act, the landlord must respond to repair requests. Keep copies of all communication.

Yes. If your landlord fails to address mould after you've reported it and allowed reasonable time for repair, you can apply to the Victorian Civil and Administrative Tribunal (VCAT) for an order requiring the landlord to carry out repairs. VCAT can also award compensation for rent reduction if the property was not fit for habitation. Application fees are modest (around $65 for tenants).

Under the Residential Tenancies Act 1997, urgent repairs include anything that makes the property unsafe or insecure. Severe mould that poses a health risk — particularly where vulnerable people (children, elderly, immunocompromised) reside — can qualify as urgent. If the landlord doesn't respond within the timeframe for urgent repairs, tenants may arrange repairs up to $2,500 and seek reimbursement.

No. Victorian tenancy law does not allow tenants to withhold rent, even if the property has mould or other maintenance issues. Withholding rent can result in a breach notice and potential eviction. The correct process is to report the issue in writing, allow reasonable time for repair, and apply to VCAT if the landlord fails to act. VCAT can order a rent reduction.

If mould makes the property unfit for habitation and the landlord refuses to remediate after proper notification, you may be able to apply to VCAT to have the tenancy agreement terminated without penalty. Document everything, obtain a professional mould assessment, and seek advice from Tenants Victoria (the state's tenant advocacy service) before taking action.
