In a house, that question answers itself. In an apartment building with shared pipes, shared walls, and a body corporate involved, it is genuinely complicated.
The Drain You See Is Not Always the Drain That Matters
Your apartment plumbing isn’t a standalone system. The bathroom drain connects to internal pipes for your unit alone, but they all dump into a shared main line running through the whole building. The exact spot where your private pipe joins that shared stack is the most critical detail when a clog happens because it decides who is actually responsible for the repair bill.
That junction is where responsibility splits. Everything on your side of it is yours to deal with. Everything past it, the shared lines running through walls and beneath floors that serve the whole building, belongs to the owners corporation. Consumer Affairs Victoria is clear that owners corporations must maintain and repair common property, and shared drainage infrastructure sits firmly in that category.
The problem is that a blockage does not arrive with a label telling you which side of that junction it is on.
Why This Causes So Many Arguments
Your shower backing up does not automatically mean the problem is inside your apartment. Shared lines further down the building can block and your unit ends up showing the symptoms first, simply because of where you sit in the pipe system. The neighbour upstairs might have no idea anything is wrong yet.
Boyd Corporate knows this, and a lot of them use it. The default response is to tell the lot owner it is an internal issue and leave it there. Sometimes that is accurate. Often it is not. Either way, nothing gets inspected quickly, the blockage keeps building, and you are left without a functioning bathroom while two parties argue about paperwork.
The Victorian Building Authority requires a licensed plumber for all residential drainage work, whoever ends up paying for it. So if someone floats the idea of a quick DIY fix while the dispute plays out, that is worth pushing back on.

If You Are Renting, Go to Your Landlord First
A lot of tenants go straight to the body corporate when something goes wrong with drainage. That is understandable, but it is the wrong move. The body corporate does not have a direct relationship with you as a tenant. Your landlord or property manager does, and keeping the property in reasonable condition is their obligation, not the strata manager's.
Tenants Victoria classifies this as an urgent repair. Report it to your landlord in writing, keep the record, and let them sort out whether the body corporate is involved. That part is not your problem.

The Moment You Notice It, Start a Record
Write down the date. Note which drains are affected. Knock on a neighbour’s door if you can, because if two or three units are backing up at the same time, that is your clearest evidence that the problem is in a shared line. Body Corporate finds that very hard to argue with.
Blocked drains in apartment buildings do not fix themselves. They get worse, and when water starts finding alternative routes through a shared structure, the repair bill tends to grow well beyond what a simple drain clearing would have cost.

FAQs
Q: Who is responsible for a blocked drain in an apartment?
Ans: It follows the pipe. If the blockage is in the pipe servicing only your apartment, it’s on you. If it is in the shared line serving multiple units, the body corporate handles it.
Q: How do I know if my blocked drain is on common property?
Ans: Look out for multiple units backing up at the same time. That is a dead giveaway that the issue is in the shared system.
Q: Can a tenant call a plumber directly for a blocked drain?
Ans: Look at the lease first. The landlord generally needs to arrange and authorise the repair.
Q: Does the body corporate have to fix a shared drain blockage?
Ans: Yes. Strata laws make common property drainage their legal obligation. They cannot push the invoice onto a single lot owner.
Q: Do I need a licensed plumber for drain work in Victoria?
Ans: Yes. The Victorian Building Authority does not leave room for DIY on drainage. If something goes wrong after unlicensed work, your insurer will find out, and the conversation that follows tends to be an expensive one.
