Who Pays for the Leak? Strata Plumbing Responsibility in Queensland
The single most argued-about question in Queensland strata is who pays for a plumbing repair. The answer usually hinges on one thing: where exactly the failure sits relative to the lot boundary.
The Basic Rule
The body corporate maintains common property. The lot owner maintains everything within their lot. For plumbing, common property generally includes shared sewer and waste stacks, water risers serving more than one lot, and pipes embedded in common property structure.
Anything serving only your unit — your tapware, cistern, in-lot branch pipes and your own hot water unit — is yours.
Where the Boundary Actually Sits
Your lot boundary is defined by the plan of subdivision, not by common sense. In a standard format plan (townhouses) it's often the property boundary line on the ground. In a building format plan (units) it's typically the centre of the floor, wall and ceiling. That distinction changes the answer for pipes inside walls.
Utility Infrastructure Can Cross the Line
Queensland legislation treats certain utility infrastructure servicing more than one lot as common property even where it physically runs through an individual lot. So a shared stack passing through your bathroom wall is usually not your problem.
Why Diagnosis Matters More Than Argument
Committees waste months arguing about liability before anyone has established where the water is coming from. Get a plumber to find the source first, with photos, moisture readings and CCTV where relevant. Once the source is documented, responsibility is usually obvious.
Insurance and Resulting Damage
Even when a lot owner is liable for the failed pipe, the body corporate's building insurance often covers the resulting damage to the building. The repair to the pipe itself and the owner's contents are separate questions. Report early — late notification is a common reason claims get reduced.
Practical Steps for Owners
Notify the body corporate manager in writing as soon as you notice a leak, take dated photos, don't authorise major works unilaterally if you believe it's common property, and ask for the diagnostic report in writing.
Frequently Asked Questions
Can I just get my own plumber and send the bill to the body corporate?
Generally no. Unless it's a genuine emergency, unauthorised works on common property often won't be reimbursed. Notify first, in writing.
Who pays for the leak detection itself?
Usually whoever engages the plumber, but many committees agree up-front that the party found responsible bears the diagnostic cost.
What if the leak comes from the unit above me?
If it's their in-lot pipework, it's their responsibility. If it's a shared stack passing through their unit, it's usually common property.
