Landlord Responsibilities for Mould in SA Rentals

As a South Australian landlord, mould in your rental property isn’t just a maintenance issue — it’s a legal liability. Understanding your obligations helps you protect both your tenants and your investment.

Your Legal Obligations

Under the SA Residential Tenancies Act 1995, Section 67, you must maintain the property in a “reasonable state of repair.” This includes addressing structural causes of mould: rising damp, water leaks, inadequate ventilation, and condensation from building defects.

What You’re NOT Responsible For

Mould caused by tenant behaviour — drying clothes indoors with windows closed, not using bathroom exhaust fans, blocking ventilation — is the tenant’s responsibility. But proving tenant-caused mould requires evidence, which is where professional inspection becomes invaluable.

The Smart Landlord Approach

1. Include mould prevention guidance in the lease
2. Ensure all exhaust fans work at lease commencement
3. Conduct regular property inspections noting any mould
4. Respond promptly to mould reports (documented response)
5. Get professional assessment to determine the cause objectively

Proactive mould management protects tenant health, preserves your property value, and minimises SACAT risk. View typical costs and get connected with qualified specialists.
