In NSW, responsibility for water damage in a rental depends on its cause. The landlord generally handles damage arising from plumbing faults, building defects or required maintenance. A tenant may be responsible if they, an occupant or a guest caused or worsened the damage, including by delaying the report of an obvious leak.
How the cause affects responsibility
| Cause | General responsibility |
|---|---|
| Burst pipe, failed fixed plumbing fixture, serious roof leak or maintenance defect not caused by the tenant | The landlord generally arranges repairs to the fault and premises. |
| Overflowing bath or sink, misuse-related blockage, damaged fitting, or careless or deliberate action by a tenant, occupant or guest | The tenant may be responsible for the resulting damage. |
| Property fault followed by delayed reporting | The landlord generally remains responsible for the original fault, but the tenant may be responsible for avoidable additional damage. |
Responsibility depends on causation and evidence, not simply where the water appeared. For a burst service, the specific rules around a burst pipe in a NSW rental help explain the usual repair duties.
It may also be necessary to establish whether the failed pipe is privately owned or part of Sydney Water infrastructure. Relevant evidence can include the tenancy agreement, condition report, photographs, written notifications and a licensed plumber’s findings. Any final legal determination will depend on the circumstances.
What should a tenant do?
- Report it immediately: Contact the landlord or agent using their urgent-repair details, then confirm the time, location and apparent severity in writing.
- Limit further damage safely: Stop using the affected fixture. If the main water shut-off valve is readily accessible and safe to reach, turn it off. Do not dismantle fittings or attempt plumbing repairs.
- Document the damage: Take photographs or video and move belongings away from clean water where safe, without delaying urgent action.
- Stay clear of electrical hazards: If water may have reached wiring, switches, appliances or the switchboard, do not enter standing water or touch electrical equipment. Call 000 if there is an immediate danger. Otherwise, contact the landlord or agent and an appropriately licensed professional.
- Avoid contaminated water: Keep people and pets away from sewage or other contaminated water and do not attempt an unprotected clean-up.
Serious leaks, burst water services and flooding may be urgent repairs under NSW tenancy rules. If the landlord or agent cannot be contacted, follow current NSW Fair Trading guidance before arranging work.
