Is the owners corporation or the lot owner responsible for a plumbing leak in a Melbourne strata?

It depends on where the pipe is. The owners corporation is responsible for pipes in common areas or serving multiple lots. The lot owner is responsible for pipes within their lot serving only their lot. The boundary is typically the lot boundary in the plan of subdivision.

Who is responsible for a strata drain blockage in Victoria?

A blockage in a shared drainage stack that serves multiple lots is typically the owners corporation's responsibility. A blockage in a private drain serving only one lot is the lot owner's responsibility. CCTV inspection can identify the exact location of the blockage relative to lot boundaries.

Can a strata lot owner arrange urgent plumbing repairs themselves?

If the owners corporation fails to respond to an urgent strata repair within a reasonable time, lot owners may be able to arrange emergency repairs and seek reimbursement, depending on the OC rules and Victorian owners corporation legislation. Legal advice is recommended for disputed cases.

Strata Plumbing in Melbourne — Who Is Responsible for What?

Plumbing responsibility in strata buildings is one of the most disputed issues between lot owners and owners corporations in Melbourne. The answer depends on where the pipe is, what it serves, and what the relevant legislation says.

The Basic Rule: Common Property vs. Lot Property

In Victoria, strata plumbing responsibility is divided between:

Owners Corporation (OC): Responsible for common property plumbing — pipes and infrastructure that serve more than one lot, or that are in common areas
Lot Owner: Responsible for plumbing within their lot that serves only their lot

The boundary is defined by the lot boundaries in the plan of subdivision — typically the inner surface of external walls, or as specified in the owners corporation rules.

What the Owners Corporation Is Typically Responsible For

Sewer main serving the building
Stormwater drainage in common areas
Hot water boiler or central hot water system (if common)
Pipes within common area walls (corridor, lobby, car park)
Pipes that serve multiple lots (shared drainage stack)
Roof plumbing, gutters, and downpipes
Water supply to the building boundary

What the Lot Owner Is Typically Responsible For

All pipes, fittings, and fixtures within their lot
Hot water system servicing their lot only
Toilet, shower, bath, and basin within the lot
Flexi hoses under sinks and behind toilets
Kitchen and laundry plumbing within the lot

Grey Areas and Disputes

The most common disputes arise around:

Leaks through floor slabs: A pipe within Lot A’s slab may be the lot owner’s responsibility even though it’s causing damage to Lot B below
Shared drainage stacks: A blockage in a shared stack typically falls to the OC, but the cause may have been from within one lot
Individual hot water systems in common cupboards: If the HWS is in a common area but serves only one lot, check the plan and OC rules

For disputed repairs, a plumber can identify the pipe location relative to lot boundaries and document findings — useful for VCAT or insurance claims.

Urgent Repairs in Strata

In a strata building, urgent plumbing repairs (burst pipe, sewage overflow, no hot water) still require a 24-hour response under Victorian tenancy law if the property is rented. The owners corporation must have a process for emergency trades contact.
