Strata properties with multiple homes come with a layer of complexity that standalone homes don’t have. When there is a plumbing issue, such as a burst pipe, the first question usually isn’t – how do we fix it? The second question is usually – whose responsibility is it?
Common area plumbing, individual lot connections, body corporate obligations, all of these things come into play, and getting one of them wrong can end up causing delays on the repairs, disputes between members or increased costs and damage to the properties.
For strata managers and owners corporations across Melbourne, understanding how plumbing responsibility works, who is responsible for routine maintenance and what happens in an emergency is essential, both for day-to-day upkeep and for handling the big plumbing crisis when it happens.
In this article, we’ll look at who’s responsible for what in a strata or owners corporation property, where the line sits between common area and private lot plumbing, what routine maintenance should look like, and how to handle a plumbing emergency when one inevitably arises.
Who’s Responsible? Strata vs Owners Corporation vs Individual Lot Owners
The responsibility of a plumbing emergency in Victoria, depends on who is affected by a pipe burst, or the plumbing issue. If it impacts the whole building it is a strata issue. If it is just one unit, then it’s the individual lot owner.
Before we delve deeper into the details, a quick clarification. Strata and Owners Corporation is more or less the same thing. Strata is the ownership system while an Owners Corporation is the legal group of people who own and manage that property. They are interchangeable phrases.
The responsibilities of a Strata include:
- Shared Infrastructure. The main water supply lines to all properties, stormwater drains servicing all units, and any shared sewage facilities.
- Common Property Pipes. Any pipes passing through common areas or gardens.
- Investigations. Arranging for, and paying for, plumbing investigations to find a leak or the source of the issue that is hidden or disputed between two or more units.
Individual lot owners within a strata are responsible for:
- Internal Plumbing. Anything inside the home, such as toilets, sinks and basins.
- Exclusive-use Pipes. Any branch pipes from the main pipes that exclusively service that apartment or home.
- Appliance Connections. Any connections for private appliances, such as dishwashers, washing machines or hoses in the backyard.
Common Areas vs Private Lots: Where the Plumbing Line Is Drawn
Plumbing responsibilities in Melbourne are determined by the Plan of Subdivision, the Owners Corporations Act 2006 and if a pipe serves multiple units or just one.
Following on from above, if there is a dispute over whose responsibility the plumbing falls under, which can get heated due to costs of repair, there are three things you can do to resolve the issue fairly:
- Check the plan: Your property’s registered plan of subdivision officially marks where private airspace ends and common property begins.
- Get a report: Hire a licensed plumber to run a CCTV drain or leak inspection to find the exact origin and purpose of the compromised pipe.
- Notify early: Inform your strata manager or OC committee before fixing hidden or structural lines to ensure proper protocol or insurance paths are followed.
Routine Maintenance for Strata Buildings
For strata buildings in Melbourne, routine plumbing involves maintaining common area facilities and systems, such as shared sewerage drains, riser stacks and common water lines. Victorian law states that Owners Corporations must properly maintain pipes and services that serve multiple housing units on one property.
Core Routine Maintenance Tasks
- Drain Clearing: Cleaning and CCTV-inspecting of main sewer and stormwater lines to stop invasive tree root blockages.
- Hot Water Servicing: Inspecting shared or central hot water systems to ensure steady building supply.
- Pumps and Meters: Testing and servicing sewage ejector pumps, stormwater sump pumps, and water meters.
- Gutter and Downpipe Care: Clearing roof drainage infrastructure to prevent overflow and structural water damage.
Annual or bi-annual professional plumbing inspections are recommended to comply with Victorian standards and reduce costly emergency repairs. Licensed plumbers should providecondition reports and compliance certificates required for building insurance files.
Common Strata Plumbing Issues
Some common plumbing problems that impact Melbourne multi-dwelling buildings include sewerage blockages, basement stormwater pump failures and clogged roofing drains. Again, resolving these problems depends on if they service the whole complex or just an individual unit within that complex.
Frequent Multi-Dwelling Plumbing Problems include:
- Shared Sewer and Drain Blockages: Tree roots or grease buildup in main sewer lines can cause waste to back up into ground-floor apartments.
- Water Hammer and Noisy Pipes: High water pressure or loose brackets inside shared building walls create loud banging sounds that can weaken joints over time.
- Car Park and Basement Flooding: Heavy Melbourne storms overwhelm sub-surface stormwater drains or cause failures in shared sump pumps.
- Hidden Stack and Balcony Leaks: Slow leaks behind common walls or failed balcony waterproofing membranes lead to silent structural damage and mould.
What Counts as a Plumbing Emergency in a Melbourne Strata Property
In Melbourne, a plumbing emergency is legally defined as any urgent fault or damage that threatens a resident’s safety, causes active structural damage, or compromises essential services such as water, sanitation and gas. Under the Victorian Owners Corporations Act 2006, the Owners Corporation (OC) is strictly responsible for fixing emergencies on common property, while the individual lot owner must handle emergencies inside their private unit.
The standard criteria for a plumbing emergency include:
Burst Water Pipes: Active, uncontrollable water flowing inside common walls, ceilings, or concrete slabs.
- Sewage Backups: Blocked main sewer lines causing raw sewage to overflow into common areas.
- Complete Water Loss: An unexplained, total disruption of the main water supply to the entire building.
- Gas Leaks: Any suspected gas smell or confirmed leak along shared structural lines or main meters.
- Severe Roof & Gutter Leaks: Uncontrolled water cascading through the roof or pooling in structural foundations during severe weather.
- Total Hot Water Failure: The complete breakdown of a centralized, shared building hot water plant.
- Substantial Water Wastage: Broken fixtures or mains that are causing massive, un-isolatable water loss.
How to Handle a Plumbing Emergency as a Strata Manager or Owner
Managing a plumbing emergency, regardless of ownership, requires immediate action by strata management. The quicker you can identify a problem and understand if it impacts common property or private property, the quicker the issue can be resolved.
The first steps are:
- Stop the water. Turn off the water meter or the emergency isolation valve for the affected area.
- Make it safe. Clear the area of people. Check to see if there is a risk of electrocution or collapsing ceilings due to water pooling.
- Take photos. Take clear photos, or video, of what is going on. Find the source of the leak, document the extent of the damage, all before repairs and cleanup begin.
The next steps are:
- Call the professionals. Contact your strata’s designated emergency contractor, or a local expert such as us here at Around Town Plumbing.
- Notify management. Let your strata management team know of the situation and that you have called in help. Call them, and follow up with an email or text message, so it is in writing.
- Insurance. Check the Owner’s Corporation insurance policy for structural damage, or coordinate private contents insurance claims if personal belongings have been impacted.
