Knowing which pipes belong to whom is genuinely useful information before something goes wrong.
The Legal Starting Point
Strata law in Australia draws a clear line between lot property and common property. Your lot is everything that exists within your apartment to serve you specifically. Common property is pretty simple to define - if it serves the whole building, it’s everyone’s. And legally, that means the owners corporation has to keep it in good repair.
Consumer Affairs Victoria confirms that shared plumbing infrastructure falls under common property. The building’s main water supply lines, the risers pushing hot and cold water up through multiple floors, and the drainage pipes collecting waste from several apartments before exiting the building are all the body corporate’s responsibility to maintain. Not something that can be passed down to individual lot owners when a repair comes due.
The boundary between common property and lot property is a legal one. It sits at the point where a pipe stops working for the whole building and starts working exclusively for your unit.
The Body Corporate’s Side of the Line
Shared water mains, building risers, and drainage infrastructure running through common walls or shared spaces are common property. Plumbing in basement plant rooms, roof installations, or shared service ducts is the body corporate’s responsibility. A good rule of thumb: if a pipe is doing a job for more than one apartment, it almost certainly belongs to the owners' corporation - and that includes pipes running through the building’s structure, even if they pass close to or through a space near your unit.

Your Side of the Line
The moment a pipe exists solely to serve your apartment, the responsibility shifts to you. Your internal hot water pipes, bathroom and kitchen tap fittings, waste pipes beneath your sink, and the braided flexi hoses connecting your toilet and vanity are all lot property.
Flexi hoses are worth a specific mention because they fail more often than people expect and cause more damage than they should. They sit out of sight, they age, and a failed hose can push out hundreds of litres before anyone notices. The Victorian Building Authority requires licensed plumbers for all work on these fittings, and with good reason. When a flexi hose fails inside a lot, the body corporate has no obligation to contribute to the repair or the resulting damage.
Get your flexi hoses and internal plumbing inspected before they become an emergency. Ezy-Plumb offers water leak detection across Bayside Melbourne.
When Nobody Can Agree on the Boundary
Water damage moves. It works its way through ceilings, walls, and floors before it ever becomes visible and tracing it back to a single pipe is harder than most people expect. That’s exactly the point where strata disputes tend to dig in and stall.
The Strata Community Association Australia advises documenting all damage from the outset, putting all communication with the owners corporation in writing, and pushing for a formal inspection before accepting any repair costs. A camera inspection of the pipe system will locate the source, and once the source is confirmed, the question of who pays tends to answer itself.
Do not accept a verbal dismissal from a strata manager. Get the inspection, get the evidence, and go from there.
Ezy-Plumb uses drain inspection cameras to locate the source of plumbing problems precisely. No guesswork, no argument. Call 0402 169 096.
FAQs
Q: What shared plumbing is the body corporate responsible for?
Ans: Building risers, shared water mains, and drainage lines serving multiple units are all common property and the body corporate’s responsibility.
Q: Where does my plumbing responsibility begin in a strata building?
Ans: At the point where a pipe branches off from shared infrastructure and exists solely to serve your apartment.
Q: Who pays if a shared pipe causes water damage to my unit?
Ans: The body corporate covers repairs to common property. Document everything and notify them in writing from the moment damage appears.
Q: Are the hot water pipes inside my apartment my responsibility?
Ans: Yes, internal pipes that only serve your unit are lot property, plain and simple. Maintaining them is your responsibility, not the owners corporation's.
Q: Can I do my own plumbing repairs inside my apartment in Victoria?
Ans: No, Victorian law is pretty clear on this one. All residential plumbing work has to be carried out by a licensed plumber under the Victorian Building Authority’s rules.
