On 1 July 2025, Victoria’s VBA to BPC Transition took effect: the Victorian Building Authority ceased to exist as a standalone regulator. In its place stands the Building and Plumbing Commission, a single body that now holds the functions previously split across three organisations: the VBA itself, Domestic Building Dispute Resolution Victoria, and the domestic building insurance arm of the Victorian Managed Insurance Authority. For anyone commissioning or delivering a commercial project in the Geelong region, this is more than a change of letterhead. It signals a regulator with broader powers and a longer reach, and it changes the way risk is carried across the life of a build.
This article sets out what has actually changed, what is still to come, and where it matters most for commercial clients. The short version: the rules around defects, payment and documentation have tightened, and the practical response is better record-keeping and earlier builder involvement, not panic.
One Regulator, Wider Powers: The VBA to BPC Transition Explained
The logic behind the merger was consolidation. For years, a consumer or developer with a problem had to work out which of several bodies held the relevant authority. The Commission now provides a single point of contact for registration, dispute resolution, insurance and enforcement. Existing registrations and licences carried across automatically and remain valid until their usual expiry, so practitioners did not need to re-apply. From 1 July 2025, correspondence simply began arriving under the new name.
The more substantial shift is in enforcement. The Commission has been equipped with stronger tools to act against poor work, and the legislation underpinning it continues to expand those powers through 2026. For commercial clients, the headline change is the one most likely to affect a project years after the keys are handed over: rectification orders.
Rectification orders: the long tail of accountability
Under the previous framework, a regulator’s ability to compel a builder to fix defective work after an occupancy permit had issued was limited. The Commission can now issue rectification orders for incomplete, non-compliant or defective building work, and those orders can be made up to ten years after the occupancy permit or certificate of final inspection was issued.
This matters because the most expensive defects are frequently the ones discovered late: water ingress at a balcony junction, a waterproofing membrane that fails behind tiling, a façade detail that admits moisture into the structure. A ten-year window means the quality of a junction detailed and sequenced today can become a formal compliance matter well into the next decade. For clients, that is a strong argument for valuing build quality over the lowest tender — a distinction we unpack in our article on why the cheapest tender is rarely the lowest cost. For builders, it raises the premium on getting the difficult details right the first time and documenting that they were.
Documentation is now a form of protection
The practical consequence of the VBA to BPC Transition’s expanded defect powers is that paperwork has shifted from administrative housekeeping to genuine risk management. Variation records, inspection sign-offs, compliance certificates, product specifications and photographic evidence of concealed work all become the evidence base if a question is raised later. A builder who can produce a clear, dated record of how a waterproofing detail was installed, by whom, and to which standard, is in a far stronger position than one relying on memory.
This is where the choice of builder and the rigour of their site systems earns its keep. At Fox Building Group, the discipline of documenting concealed work and material junctions is part of how we deliver commercial construction — not because a regulation demands a particular form, but because good records protect the client and the project long after completion.
Payment reform runs alongside
The VBA to BPC Transition has not arrived in isolation. Changes to Victoria’s Security of Payment framework commenced on 15 April 2026, tightening payment timeframes and bringing the state closer into line with other jurisdictions. The intent is to improve cash flow for subcontractors and suppliers and to make payment claims easier to adjudicate when a dispute arises. For a commercial principal, the takeaway is that contract administration and payment scheduling now sit under sharper scrutiny, and a builder running disciplined payment processes reduces the risk of a dispute stalling the job.
A new insurance landscape
The domestic building insurance function now sits inside the Commission, and a new Statutory Insurance Scheme has now been introduced, with requirements commencing on 1 July 2026. For developers of apartment buildings above three storeys, a developer bond set at a percentage of the estimated total build cost is now part of the pathway to an occupancy permit. These mechanisms exist to ensure funds are available to fix defects that surface after occupation. We cover the bond mechanism in detail in our guide to the Victorian Developer Bond Scheme.
What commercial clients should do now
The transition does not require existing projects to stop and reassess. It does reward a few sensible habits: choose a reputable builder with demonstrable site documentation systems, treat build quality at concealed junctions as a long-term liability rather than a line item, and confirm early which compliance obligations attach to your building’s class and height. Most of all, it favours bringing construction expertise into a project before the design is locked, where buildability and compliance can be resolved on paper rather than on site.

Frequently asked questions
What is the Building and Plumbing Commission in Victoria?
The Building and Plumbing Commission, or BPC, is Victoria’s building and plumbing regulator created through the VBA to BPC Transition. It commenced on 1 July 2025, bringing together the former Victorian Building Authority, Domestic Building Dispute Resolution Victoria, and the domestic building insurance function of the Victorian Managed Insurance Authority into a single regulator.
Did the VBA to BPC change affect existing registrations?
No. Current registrations and licences transitioned automatically to the Commission and remain valid until their usual expiry date. Practitioners did not need to take action; from 1 July 2025, correspondence simply carried the Commission’s name and details.
How long after completion can a rectification order be issued?
A rectification order for incomplete, non-compliant or defective building work can be issued up to ten years after the date the occupancy permit or certificate of final inspection was issued.
Does the transition change how commercial builds are documented?
In practice, yes. With expanded powers to address defects after occupancy, thorough site documentation — variation records, inspection sign-offs and evidence of concealed work — has become an important protection for both client and builder.
