How Common Property Is Defined
Australian strata law separates individual lot owner responsibility from common property managed by the owners corporation. Plumbing accountability depends entirely on service function: lines servicing a single apartment belong to that individual owner, whereas any infrastructure connecting to multiple lots or the entire building is common property.
The NSW Fair Trading Strata Living guidelines spell this out clearly for New South Wales residents. The definition of common property includes pipes, cables, and other services that pass through or beneath common areas or shared structures. The same principle applies in other states, though the specific legislation differs.
The Problem With Drain Pipes
Unlike structural boundaries, utility plumbing layout networks travel through hidden cavities across individual lot borders. While independent fixtures like kitchen sinks belong strictly to the individual lot owner and central vertical service stacks constitute common property, the intermediate connecting pipework remains a frequent source of ownership disputes.
When a plumber clears a blockage from inside your unit and the problem keeps coming back, the blockage is often sitting in that shared section further down the line. At that point, the repair becomes the owners corporation’s responsibility, not yours.
What Your State’s Laws Say
Every Australian state has strata or community title legislation that governs this question. In Queensland, the Queensland Government body corporate resource sets out how the Body Corporate and Community Management Act defines and allocates responsibility for common property maintenance. In Victoria, Consumer Affairs Victoria’s owners corporation section covers the same ground under Victorian law. If you are elsewhere, your state’s fair trading or consumer affairs office is the place to look.
The owners corporation faces an absolute statutory obligation to maintain common property infrastructure. Failure to keep a shared drain in good repair creates clear liability for subsequent lot damage. Individual owners can pursue the building for all consequential repair costs resulting from the plumbing failure.
Practical Steps When You Are Not Sure
Determining plumbing responsibility requires checking the official strata plan alongside a physical inspection by a licensed plumber. If the defect sits within a shared common property line, lodge a formal written notification with the strata manager and keep a copy to secure your legal position against repair delays or progressive property damage.
Ezy-Plumb provides strata drain inspections and clearing across Australia. Book a licensed plumber who knows how strata plumbing works.
When the Owners Corporation Will Not Act
If you have reported a shared drain issue and the owners corporation is not responding within a reasonable time, you have options. Each state has a formal strata dispute resolution pathway. The Strata Community Association Australia is a useful national resource for understanding how that process works and finding qualified strata advisers who can guide you through it.
Document every step. Dates of reports, names of people you spoke to, photos of the ongoing problem. That record becomes important if the matter ends up before a tribunal.

Frequently Asked Questions
Q: If a drain is inside my apartment walls, does that make it my responsibility?
Ans: Not if the pipe services other lots. Shared infrastructure stays under strata ownership regardless of its physical path.
Q: Our building has an old drain that keeps blocking. Who should fix it?
Ans: The executive committee must resolve the issue. Individual lot owners are not liable for maintaining shared plumbing lines.
Q: Can I hire my own plumber to fix a shared drain and bill the owners corporation?
Ans: Unilateral bookings cause heavy financial risk. Request strata intervention first to ensure the building covers the invoice.
Q: What is a strata plan and how does it help with drain disputes?
Ans: This document holds the final legal answer. It maps the property boundaries to clear up plumbing ownership confusion.
Q: Does the owners corporation have to fix common property drains within a set timeframe?
Ans: The law demands active infrastructure upkeep. Unreasonable delays violate strata regulations and allow for immediate tribunal escalation.
