Rental Property Water Damage

Water damage in rental properties sits at the intersection of property law, insurance, and building maintenance obligations. The key question — who pays — is determined primarily by the cause of the damage and the obligations imposed by each state and territory's Residential Tenancies Act.

• Landlord's core obligation: All Australian Residential Tenancies Acts require landlords to maintain the property in a reasonable state of repair throughout the tenancy. This includes the roof, walls, plumbing, and drainage. Water damage caused by the building structure — burst pipes, roof leaks, failed waterproofing, blocked gutters — is the landlord's responsibility to repair and restore.
• Urgent repairs and the 24-hour rule: Burst pipes, major roof leaks, and similar events qualify as urgent repairs in all states. Most legislation requires landlords to attend to urgent repairs within 24 hours of being notified. Failure to do so is a breach of the residential tenancy agreement and triggers the tenant's right to arrange emergency repairs themselves (within the statutory cap) and seek reimbursement.
• State statutory repair caps: If the landlord fails to act, tenants may organise emergency repairs up to the following limits and claim reimbursement: QLD $1,500; NSW $1,000 plus one week's rent; VIC $2,500 or one month's rent; SA — a reasonable amount for urgent repairs; WA $1,000; ACT — reasonable costs; TAS and NT also permit emergency repairs by tenants with reimbursement rights. In all cases, tenants must notify the landlord in writing before acting and retain all invoices.
• Tenant-caused damage: If the tenant directly caused the water damage — such as leaving a tap running, overflowing a bathtub, or damaging a pipe — the tenant is liable for the cost of repair. Tenants should hold a contents insurance policy that includes accidental damage and liability cover.
• Notification obligations: Tenants in all states are obligated to notify the landlord or property manager promptly upon discovering any damage, leak, or required repair. Delayed notification that worsens the damage may reduce or eliminate the tenant's reimbursement rights.

Landlord insurance is a specialist policy covering investment and rental properties. Understanding what it covers — and importantly, what it excludes — is essential for landlords managing a water damage event.

• Building structure damage — covered: Sudden water events that damage the building structure — burst pipes, storm water ingress through the building envelope, roof damage causing internal water damage — are covered under the building section of most landlord policies. The insurer pays for structural repairs and water damage restoration to the building fabric.
• Tenant-caused damage — covered: Most landlord policies include malicious or accidental damage by tenants as a specific benefit. This covers damage beyond the bond amount, including water damage caused by a tenant's negligence. A condition report and photographic evidence from the commencement of the tenancy is required to support these claims.
• Gradual leaks — excluded: Gradual or slow leaks — a tap dripping for months, a slow roof leak that was visible but not reported, seepage through defective pointing — are excluded under most landlord and home insurance policies. Policies cover sudden and unforeseen events, not gradual deterioration. Regular inspections by the property manager help identify slow leaks before they become exclusion events.
• Rent loss during restoration — typically covered: If the property is uninhabitable following a covered water event, most landlord policies include rent loss cover. The insurer pays the weekly rental rate from the date of uninhabitability until a defined period after restoration is completed. Policies generally require restoration to be completed within 12 months; some specify shorter periods.
• Contents — not covered by landlord insurance: Landlord insurance does not cover the tenant's personal belongings. Tenants need their own contents insurance. Fixtures and fittings owned by the landlord (light fittings, window coverings, built-in appliances) are typically covered under the building section of the landlord policy.

Review your Product Disclosure Statement carefully — policy terms vary significantly between insurers. If your claim is disputed, you can escalate through your insurer's Internal Dispute Resolution process and, if unresolved, to AFCA.

Mould in rental properties has become a major focus of residential tenancy legislation across Australia. QLD, NSW, and VIC have introduced or strengthened landlord obligations regarding mould in recent legislative amendments.

• Mould caused by a water event = landlord's responsibility: If mould develops as a result of a storm water ingress event, burst pipe, roof leak, or other structural water event, the mould remediation is the landlord's obligation and is claimable under landlord insurance. The landlord cannot attribute this mould to the tenant.
• QLD: Under the Residential Tenancies and Rooming Accommodation Act 2008 (amended 2021), landlords must ensure the property is fit for habitation and address mould attributable to the building structure promptly. Tenants can apply to QCAT for orders requiring remediation.
• NSW: Under the Residential Tenancies Act 2010, properties must be fit for habitation. The Rental Fairness Act 2024 amendments strengthened obligations around mould caused by building defects. Tenants can apply to NCAT for urgent repairs orders covering mould.
• VIC: Under the Residential Tenancies Act 1997 (amended 2021 minimum standards), properties must meet minimum rental standards including adequate ventilation and weatherproofing. Mould caused by a structural failure is the landlord's obligation; tenants can apply to VCAT.
• Mould caused by tenant behaviour: If mould develops due to the tenant consistently failing to ventilate, drying clothes indoors, or blocking vents in an otherwise structurally sound property, the tenant may bear responsibility. A professional mould assessment that identifies the moisture source is essential evidence in disputed causation cases before any tribunal.
