Building and Plumbing Administration and Enforcement Bill 2026: What It Means for Homeowners and Builders

1. What the Bill Does: A New Principal Act for Victoria's Building System

The Building and Plumbing Administration and Enforcement Bill 2026 is not an amendment to the existing Building Act 1993 (Vic). It creates an entirely new principal Act — a standalone statute that formally governs the administration and enforcement of Victoria's building and plumbing system going forward.

The centrepiece is the formal legal constitution of the Building and Plumbing Commission (BPC) as a body corporate. Under Chapters 3 and 11 of the Bill, the BPC is established as a legal entity in its own right, capable of suing and being sued, entering into contracts, holding property, and exercising statutory powers in its own name. This replaces the Victorian Building Authority (VBA) at law — an entity that, in practice, has already been superseded operationally by the BPC since the Building Legislation Amendment (Buyer Protections) Act 2025. The Bill completes that transition by removing the VBA's legal existence and substituting the BPC formally and comprehensively.

The significance of this structural step should not be underestimated. Previously, the regulatory architecture rested on the amended Building Act 1993 with the VBA as its creature. The new Bill gives the BPC its own legal foundation — with consequences for how decisions are challenged, how proceedings are commenced, and how the Commission's acts and omissions are legally characterised.

The BPC's Statutory Objectives

The Bill introduces a public interest objective for the building system, requiring that participants — including registered builders — prioritise health and safety. This objective is not merely aspirational: it informs the interpretation of the BPC's powers throughout the Act and provides the basis for enforcement action where a builder's conduct creates risk to public safety, regardless of whether a specific rule has technically been contravened.

2. Key Enforcement Powers

The Bill consolidates and significantly expands the enforcement toolkit available to the BPC and municipal building surveyors. The following provisions are the most practically significant for parties involved in Victorian building and plumbing disputes.

Entry, Search, and Seizure — Sections 284–295

Sections 284 to 295 confer entry, search, and seizure powers on BPC inspectors and municipal building surveyors. These powers permit authorised officers to enter premises (subject to warrant requirements where entry is to a private residence), inspect documents and records, examine building work, take photographs, and seize evidence of non-compliance. The powers are exercisable in connection with:

• suspected contraventions of the Act or associated regulations;
• investigations into the conduct of registered building and plumbing practitioners; and
• audits of compliance with building permits and occupancy certificates.

Where entry is exercised pursuant to a warrant, the authorising court must be satisfied on reasonable grounds that a contravention has occurred or is occurring. Practitioners and site owners should be aware that entry without a warrant is permitted in specific circumstances — including to inspect commercial building sites and premises associated with a building permit — and that resistance to lawful entry constitutes a separate offence.

Infringement Notices — Section 326

Section 326 broadens the scope of infringement notices the Commission may issue. This is an on-the-spot enforcement mechanism: an authorised officer can issue an infringement notice to a person suspected of having committed a prescribed offence, without the need to commence court proceedings. The Bill expands the range of offences for which infringement notices may be used and increases the financial amounts attaching to them. Crucially, an infringement notice does not constitute a finding of guilt and may be challenged — but failure to respond within the required period is treated as an admission.

Proceedings for Offences — Section 308

Under section 308, proceedings for offences under the Act may be commenced by the Commission itself. This removes any dependency on a government agency or external body to prosecute regulatory contraventions — the BPC has direct prosecutorial standing. Combined with the BPC's new identity as a body corporate, this creates a more agile enforcement apparatus than existed under the VBA.

Civil Penalty Orders — Section 343 and Related Provisions

Section 343 establishes additional enforcement mechanisms, including civil penalty orders that a court may make on application by the Commission. The maximum civil penalties under the Bill are:

• Natural persons: up to 3,000 penalty units;
• Body corporates: up to 60,000 penalty units.

These figures represent a material increase on the penalties available under the existing framework and reflect the legislature's intention to treat regulatory non-compliance in the building industry as a serious financial risk rather than a manageable cost of doing business.

Director Liability and Anti-Phoenixing Measures

The Bill introduces director personal liability provisions: where a body corporate contravenes the Act, a director who was knowingly involved in or who facilitated the contravention may be held personally liable. This closes the corporate veil in circumstances of deliberate wrongdoing. Complementing this, the Bill includes anti-phoenixing measures designed to prevent builders from avoiding liability by dissolving a company and immediately re-registering under a new entity. These provisions have direct relevance for homeowners pursuing claims against builders who have sought to liquidate companies mid-project.

Immunity for Good-Faith Acts

The Bill also provides that commissioners and BPC staff acting in good faith in the exercise of their statutory functions are immune from personal liability. This reflects standard drafting for regulatory bodies and mirrors similar protections in comparable Victorian legislation. It does not, however, immunise the Commission itself from liability for unlawful exercises of power — judicial review and statutory appeals remain available.

3. New Statutory Roles Within the BPC

One of the most architecturally significant features of the Bill is the creation of a series of named statutory roles within the BPC. These roles give specific functions and responsibilities a formal legal home, replacing ad hoc administrative arrangements with defined positions that can be challenged, reviewed, and held to account.

Chief Dispute Resolution Officer

The Chief Dispute Resolution Officer (CDRO) oversees the BPC's conciliation and dispute resolution functions. The creation of this role as a distinct statutory appointment — separate from the BPC's enforcement and registration arms — reflects a deliberate policy choice to maintain the independence of the dispute resolution function. For parties engaged in BPC-administered conciliation (the required pre-step before VCAT proceedings in most residential building matters), the CDRO's office is the relevant operational unit.

Conciliation Officers and Assessors

Conciliation officers conduct conciliation conferences between homeowners and builders. Assessors are appointed to provide technical building expertise to assist in dispute resolution processes — their reports and assessments play a critical role in conciliation and can, if a matter progresses to VCAT, inform the tribunal's factual findings. Understanding the scope and limitations of an assessor's role is essential for parties preparing for VCAT proceedings.

Insurance Manager

The Insurance Manager is responsible for administering the domestic building insurance (DBI) function now housed within the BPC. This role manages the end-to-end DBI process, including claim assessment and payment. The statutory formalisation of this role matters for homeowners: it creates a named decision-maker whose determinations are reviewable, and it clarifies the governance framework for a function that directly affects a homeowner's access to insurance cover where a builder has failed to complete or rectify work.

State Building Surveyor and Building Monitor

The State Building Surveyor provides technical leadership on building surveying matters across Victoria and has functions including guidance, audit, and technical standard-setting. The Building Monitor is a new oversight role with functions in monitoring the performance of the building system and reporting publicly on systemic issues. The Building Monitor role is designed to provide greater transparency about regulatory performance — including processing times, enforcement activity, and systemic defect patterns.

4. The Building Appeals Tribunal

The Bill establishes the Building Appeals Tribunal (BAT) as the successor to the Building Appeals Board (BAB). The BAT is an independent merits review body — it reviews decisions of building surveyors, permit authorities, and in certain cases the BPC, on their technical merits rather than on purely legal grounds.

Scope of Review

The BAT's jurisdiction covers decisions concerning:

• whether building work complies with the Building Act or National Construction Code;
• building permit refusals or conditions;
• occupancy permit determinations; and
• certain BPC regulatory decisions under the new Act.

Distinction from VCAT

It is important to distinguish the BAT's function from VCAT's. The BAT deals with technical regulatory decisions about what the building standards require. VCAT deals with civil disputes between parties — homeowner versus builder, contractor versus principal — including defect claims, payment disputes, and contract termination disputes. In many building matters, both forums can be relevant: a homeowner may have an active VCAT proceeding about defective work while separately contesting a building surveyor's refusal to issue an occupancy permit at the BAT.

Independence and Composition

The BAT is constituted as an independent body with technical expertise. Appointments are intended to include building surveyors and other industry professionals with relevant qualifications. The independence of the BAT from both the BPC and the permit authority whose decision is under review is a deliberate safeguard against regulatory capture — a recognised concern in building regulatory systems where surveyors and the regulator may otherwise effectively set the standards they are then called upon to review.

5. Cladding Levy Removal: The Cladding Safety Victoria Repeal Bill 2026

Introduced on the same day, the Cladding Safety Victoria Repeal Bill 2026 formally brings to a close the cladding rectification programme that has been a feature of Victoria's building regulatory landscape since 2020. The Bill:

• Repeals the Cladding Safety Victoria Act 2020;
• Abolishes Cladding Safety Victoria as a statutory body;
• Removes the Cladding Levy — the dedicated levy component of the building permit levy that funded the rectification programme; and
• Makes consequential amendments to the Building Act 1993 (Vic) regarding the building permit levy structure.

Financial Impact on Building Permits

The removal of the Cladding Levy is estimated to reduce the building permit levy by 47–66% across most project values and building classes. This is a meaningful cost reduction for residential and commercial projects alike. The levy is calculated as a percentage of the cost of building work and has represented a significant additional cost for projects above the minimum threshold.

The repeal of the Cladding Levy does not affect the domestic building insurance levy component or other components of the building permit levy. Developers, building surveyors, and permit applicants should confirm the revised levy schedule with the BPC or their building surveyor once the Bill receives royal assent and commences.

Legacy Obligations

The abolition of Cladding Safety Victoria does not extinguish obligations already accepted or works already committed to under the cladding rectification programme. Owners of affected buildings whose rectification works are already approved or underway should confirm with Cladding Safety Victoria directly as to the status of any outstanding commitments and how they will be administered through the transition.

6. What This Means for Homeowners

Stronger Regulatory Protection

The cumulative effect of the Bill's reforms is a materially stronger regulatory environment for residential building consumers. The BPC's expanded enforcement powers — including the ability to issue infringement notices, commence its own prosecutions, and seek civil penalty orders against non-compliant builders — create genuine deterrence. Builders who previously regarded regulatory action as a remote possibility now face a body corporate with direct prosecutorial standing and the resources to pursue compliance.

Clearer Dispute Pathways

The creation of the CDRO role and the formal statutory appointment of conciliation officers and assessors provides clearer accountability for the quality of dispute resolution services. For homeowners involved in BPC conciliation, the statutory framework now makes it easier to identify who is responsible for the conduct of their matter and, if the process is mishandled, on what basis a complaint or challenge may be made.

DBDRV/BPC Transition: What Has Already Changed

It is worth noting that the DBDRV has already been operationally absorbed by the BPC as of 2025 under the Building Legislation Amendment (Buyer Protections) Act 2025. The new Bill completes the legal architecture for that transition. If you have an unresolved domestic building dispute, you lodge it with the BPC — not the DBDRV, which no longer operates as a standalone entity. Following BPC conciliation, unresolved residential building disputes are referred to VCAT, which remains the primary adjudication forum for domestic building work disputes under the Domestic Building Contracts Act 1995 (Vic).

Reduced Permit Costs

Once the Cladding Safety Victoria Repeal Bill commences, homeowners undertaking residential extensions, renovations, or new builds will benefit from a significant reduction in building permit levies. For a project with a cost of works in the range typically applicable to residential work, this represents a material saving at the permit stage.

Practical Advice

If you are currently involved in a dispute with a builder — whether in BPC conciliation or VCAT proceedings — the institutional transition itself does not interrupt your matter. Existing proceedings continue under the bodies as constituted. However, if your dispute involves a builder under regulatory investigation or facing BPC enforcement action, the Bill's provisions on anti-phoenixing and director liability may have direct practical relevance to the prospects of enforcing any judgment or order you obtain.

7. What This Means for Builders

Higher Compliance Burden

The Bill substantially increases the compliance burden on registered building and plumbing practitioners. The combination of expanded inspection powers (sections 284–295), broader infringement notice authority (section 326), and direct BPC prosecutorial standing (section 308) means that non-compliance is more readily detected and more swiftly acted upon than under the previous framework. Builders should treat the BPC as an active enforcement agency, not merely a registration authority.

Serious Penalty Exposure

The maximum civil penalty of 3,000 penalty units for natural persons and 60,000 penalty units for body corporates is not hypothetical. These are the figures a court may order on application by the Commission, and the Bill's public interest objective — requiring builders to prioritise health and safety — establishes a baseline standard against which conduct will be measured. Where that standard is not met and harm results, the Commission has both the standing and the financial threshold to make enforcement worthwhile.

Director Liability Cannot Be Ignored

Directors of building companies need to be alert to the Bill's director liability provisions. The traditional protection afforded by the corporate form is qualified where a director was knowingly involved in the contravention. Combined with the anti-phoenixing measures, a director who attempts to escape liability through corporate restructuring faces specific provisions designed to address precisely that conduct. Legal advice obtained before a regulatory investigation commences is far more effective — and considerably cheaper — than advice sought after a show-cause notice or civil penalty application has been filed.

For Commercial Contractors

Commercial contractors and principals are largely outside the domestic building insurance framework but are squarely within the BPC's registration and enforcement jurisdiction. The expanded inspection powers and civil penalty regime apply to commercial building practitioners. For contractors engaged in Class 2–8 building work, the Bill's enhanced enforcement architecture — including the State Building Surveyor's audit functions and the Building Monitor's reporting role — signals an environment of increased regulatory scrutiny. Ensuring contractual compliance with permit conditions, notifiable work obligations, and inspection requirements is no longer a matter that can be treated as administrative formality.

Getting Advice Early

Whether you are a domestic builder facing a BPC investigation, a commercial contractor subject to a show-cause notice, or a plumbing practitioner managing compliance with the new Act, early legal advice is essential. The procedural steps taken in the early stages of a regulatory matter — including how you respond to inspection requests, what documents you produce, and how you frame your initial correspondence with the Commission — have direct consequences for the trajectory of any formal enforcement process. We can assist in navigating that process and representing your interests before the Commission, the BAT, and VCAT.
