Rewriting the Rules: What Victoria’s Building Reforms mean for Developers, Builders, and Homeowners

Why the Shake-Up? The Road to Reform

The 2025 reforms were not introduced in a vacuum. They are a response to growing concerns about consumer risk, industry fragmentation, and regulatory inefficacy.

In September 2023, the Victorian Government released Victoria’s Housing Statement: The Decade Ahead 2024–2034, outlining its plan to deliver 800,000 new homes in ten years. Multi-storey and mixed-use residential developments (including conversions of existing commercial buildings) were identified as critical to this growth. But with this ambition came a need for stronger consumer protections and greater confidence in the industry’s regulatory backbone.

In November 2023, the State’s Environment and Planning Committee released findings from an inquiry into employers and contractors who failed to pay subcontractors. The report made 28 recommendations, 27 of which proposed amendments to the Building and Construction Industry Security of Payment Act 2002 (SOP Act), a clear call for better enforcement mechanisms and payment protections across the supply chain.

Then in October 2024, a report by Weir Legal & Consulting “Victorian Building Authority: The Case for Transformation” made scathing observations about the VBA’s failure to effectively regulate builder conduct. Commissioned by the VBA itself, the report recommended 20 operational reforms and made the case for systemic change.

These reports laid the foundation for the Building Legislation Amendment (Buyer Protections) Act 2025 (Vic) (BLA Act), which came into effect on 1 July 2025. With it, the Government has introduced sweeping changes to how the residential building sector is regulated, insured, and held to account.

In parallel, the Government has also introduced a major overhaul of the Domestic Building Contracts Act 1995 (Vic) (DBC Act), with a reform Bill now before Parliament. These changes aim to modernise contract regulation, improve consumer protections, and enable earlier contract signing in the building process. If passed, the reforms are expected to take effect from 1 December 2026.

1. A New Regulator: The Building and Plumbing Commission

The BLA Act has the effect of replacing the VBA with a new, more powerful watchdog – the Building and Plumbing Commission. This regulator consolidates three key entities under one roof:

• The Victorian Building Authority (VBA)
• Domestic Building Dispute Resolution Victoria (DBDRV)
• The Domestic Building Insurance (DBI) arm of the Victorian Managed Insurance Authority (VMIA)

This single point of oversight aims to simplify engagement for consumers and practitioners. Implementation will roll out through 2025 and 2026.

The Commission has broader enforcement powers than its predecessors and is designed to be a proactive regulator, with responsibility for licensing, insurance, dispute resolution, and now enforcement action.

Implications:

• Centralisation will bring consistency, but also more scrutiny. With a single body overseeing licensing, enforcement, insurance, and dispute resolution, industry participants can expect a more streamlined process but also fewer cracks to fall through.
• Proactive regulation = proactive enforcement. The expanded powers and stated intention to act early may result in increased site visits, more frequent audits, and quicker escalation of complaints.
• Fewer excuses for non-compliance. Integration of the previous bodies removes a common defence: ‘I didn’t know which regulator to deal with.’
• Legal consequence: parties will need to review internal workflows, insurance triggers, and dispute pathways to ensure they are fit for the new regulatory model.
• Risk: a faster-moving regulator may lead to enforcement action earlier in the life cycle of a dispute.

2. From Last Resort to First: A New Insurance Scheme

Historically, homeowners could only claim Domestic Building Insurance / DBI as a last resort, and only when a builder died, disappeared, or became insolvent. This left many consumers without recourse when projects were delayed or defective.

Under the BLA Act, first resort insurance coverage now applies to:

• Single dwelling homes and apartment buildings up to and including three storeys
• Projects valued at over $20,000

Consumers can now claim for:

• Incomplete, non-compliant or defective work
• Lost deposits

Crucially, the insurer may require the builder to rectify or complete the works, not just provide financial compensation.

This major shift strengthens consumer rights and introduces new compliance obligations for builders. Early awareness and sound contract management will be essential to avoid disputes and liabilities under the new scheme.

Implications:

• Risk of earlier intervention. Builders may now be required to rectify issues at the first sign of non-compliance, even where disputes haven’t fully crystallised.
• Insurer will be more active. The insurer now has a direct role in mandating rectification, rather than simply paying out, leading to greater oversight of builders’ operations.
• Moral hazard for some consumers. With easier access to insurance, some owners may be more inclined to escalate concerns, valid or not.
• Legal consequence: builders need to be more rigorous in contract documentation, defect recording (completed and disputed), and communication with clients to defend against premature or unjustified claims.
• Behavioural shift: expect more disputes to emerge earlier, during or shortly after practical completion, rather than only upon any insolvency.

3. Holding Developers Accountable: The Developer Bond Scheme

To address post-completion defects, the BLA Act introduces a developer bond scheme.

From 1 July 2026, Developers must lodge a bond equal to 2% of the total build cost with the Commission before applying for an occupancy permit for any building exceeding three storeys.

Key facts:

• The bond is held for two years post-completion.
• Owners can access the bond to rectify defects if the builder fails to do so.
• From 1 July 2026, the requirement applies based on permit application date, regardless of when the construction contract was signed.

This shift places the onus back on developers to ensure quality and compliance, while also affecting cash flow planning and project financing models.

Implications:

• Major financial impact on cash flow. The requirement to post 2% of total build cost before occupancy could tie up millions in working capital, affecting funding availability for new projects.
• Increased due diligence on quality control. Developers will be incentivised to ensure the builder rectifies defects swiftly before and during the defects liability period to avoid losing the bond.
• Shift in risk profile. Investors and lenders will factor this bond into risk assessments, where projects may become less attractive if the defect risk is high.
• Legal consequence: developers may renegotiate contracts to pass responsibility (and costs) for latent defects back to builders, or seek stronger indemnities, and seek to retain performance security for longer than the usual 12-month defects liability period. KCL is already seeing this play out in contract negotiations on behalf of builders, particularly in relation to developers seeking to extend the defects liability period to 24 months, during which time the balance of security is intended by developers to be retained.
• Unintended effect: smaller or emerging developers may be priced out of the market if they can’t meet bonding requirements.

4. Enforcing Standards: Rectification Orders and Dispute Resolution

The Commission has also been granted expanded powers to compel rectification of substandard work, even after occupancy.

Key features include:

• The ability to issue rectification orders to:
  • Builders (registered or unregistered)
  • Developers (for apartment buildings)
  • Owner-builders
• Orders can be issued up to 10 years after any of the following:
  • Practical completion
  • A certificate of final inspection
  • The issuing of an occupancy permit

The 10 year period is in line with the long stop limitation period for most building actions (excluding cladding building actions) under section 134 of the Building Act 1993 (Vic).

If serious defects are not fixed:

• Occupancy permits may be withheld
• Off-the-plan sales may be blocked

Failure to comply without reasonable excuse can result in fines, disciplinary action, suspension, or cancellation of registration.

The BLA Act also makes it an offence for an owner to attempt to register land that is the subject of a rectification order.

Appeals can be made to VCAT within 28 days of the order being issued.

Implications:

• Long tail of liability. The ability to issue rectification orders up to 10 years post-completion dramatically extends risk exposure on a statutory enforcement level where previously the responsibility largely fell on private parties to pursue rectification through the courts. Builders and developers will now need robust long-term defect records (completed and disputed).
• Marketability of off-the-plan sales impacted. Any hint of unresolved rectification orders may deter purchasers, financiers, or insurers if residential property transactions are stalled whilst defects are being resolved prior to issue of occupancy permits.
• Increased project close-out scrutiny. Final inspections, certifications, and handover documents will now carry even more legal and commercial weight.
• Legal consequence: contracts will need more comprehensive rectification clauses, and practitioners should review how defect liabilities are allocated and insured.
• Industry shift: developers and builders may need to maintain longer-term relationships post-handover (or formalise post-build service models) to comply and protect their reputation.

5. Lifting Standards: Minimum Financial and Professional Requirements

To lift the standard of practice and reduce insolvency, builders must now meet minimum financial and professional requirements to retain their registration.

These include:

• Proof of appropriate insurance cover
• A training plan report to demonstrate commitment to continuing professional development
• An annual fee as prescribed in the Building Act 1993 (Vic)

This information must be submitted annually, on or before the anniversary of registration or within a shorter period approved by the Commission. It is expected that these requirements will be prescribed in the regulations and will be subject to stakeholder consultation in due course noting we are still in the very early stages of roll-out of the legislation.

Non-compliance may lead to:

• Fines
• Disciplinary action
• Suspension or cancellation of registration

While this professionalises the industry, it also risks pushing out competent but under-resourced builders unless adequate support or transitional guidance is provided.

Implications:

• Stronger vetting of builder capability. The days of low-bar entry are ending. Builders who lack financial literacy or administrative infrastructure (internally or support externally) may struggle to maintain registration.
• CPD and compliance become survival tools. Builders must treat compliance tasks (insurance, training, annual renewals) not as red tape, but as operational essentials.
• Legal consequence: non-compliance could trigger not just regulator action but disputes with project partners or financiers who rely on active builder registration.
• Cultural change: the reforms signal a shift toward professionalisation. Builders who fail to adapt may lose market credibility or be weeded out entirely.
• Transitional risk: without adequate education and support, competent but under-resourced builders may exit the market, potentially exacerbating housing supply constraints, noting a key objective of the Victorian Government is to build 800,000 new homes over the next decade, with a broader goal of 2.24 million homes by 2051.

6. Additional Consumer Protections on the Horizon

Two further reforms are currently under Government consultation:

1. A requirement for builders to provide a detailed handover manual, including materials, warranties, and maintenance information.
2. Increased mandatory inspections during construction, particularly pre-waterproofing and pre-plastering.

The outcome of the consultation is expected by late 2025, with potential implementation timelines to follow.

Implications:

• Handover manuals = more paperwork, but less ambiguity. Builders will need to invest in better information capture, from material specs to maintenance guides.
• More inspections = more delays? Increased pre-plaster and waterproofing inspections could slow build timelines, especially if inspection capacity isn’t scaled.
• Legal consequence: disputes over scope and defects may decline if documentation improves, but only if done thoroughly.
• Behavioural shift: builders may need to hire or train dedicated compliance managers to handle handover and inspection readiness.

Strategic opportunity: builders who excel in these areas can differentiate themselves as premium or trusted operators.

7. Amendments to the Domestic Building Contracts Act 1995 (Vic)

As part of its broader overhaul of the construction sector, the Victorian Government announced in 2023 a comprehensive review of the DBC Act, citing the need to modernise outdated provisions and enhance protections for consumers.

On 18 June 2025, the Domestic Building Contracts Amendment Bill 2025 (Vic) was introduced into the Victorian Parliament.

If passed, the Bill is expected to come into full operation by mid to late 2026, with most reforms commencing on 1 December 2026. Importantly, under the current draft, the new provisions will apply only to domestic building contracts entered into after the commencement date. This means existing contracts will continue to be governed by the current framework, avoiding retrospective disruption.

Key changes are expected to include:

• Stricter regulation of progress payments and deposit limits
• Enhanced rules around fixed-price contracts to reduce reliance on provisional sums and prime cost items
• Clearer definitions to clarify the scope of the DBC Act
• Removing the preparation of plans and specifications necessary to obtain a building permit from the scope of Major Domestic Building Contracts (meaning domestic building contracts could be signed earlier in the building process)
• Stronger consumer protections such as mandatory pre-contract disclosures and tighter variation controls.

KCL Law will continue to provide updates as the Bill progresses.

8. Securing Payment: Changes to the SOP Act

Reform of the DBC Act is part of a larger effort to improve integrity and fairness in Victoria’s building sector. Alongside it, the Government is also progressing significant amendments to the SOP Act.

The reforms aim to improve payment security, reduce insolvency risk and protect smaller contractors, subcontractors, and suppliers. Whilst the enactment of the new amendments are taking a little longer than expected, we can expect to see at least some of the changes come into force within the next year.

Key Takeaways

1. The VBA has been replaced by the Building and Plumbing Commission, which unites oversight, insurance, and dispute resolution under one body.
2. Homeowners now benefit from first resort insurance, enabling claims for incomplete and defective work or lost deposits.
3. Developers must lodge a 2% bond on projects over three storeys before applying for an occupancy permit, from 1 July 2026.
4. The Commission can now enforce rectification of defective work for up to 10 years after completion.
5. Builders must meet annual financial, insurance, and professional development requirements to maintain registration.
6. DBC Act reforms intend to tighten rules on payments, clarify contract scope, allow earlier contract signing and boost consumer protections, expected from 1 December 2026.
7. Proposed SOP Act reforms will extend protections to homeowner residential building contracts and require clearer communication in payment claims.

Conclusion

Together, these reforms mark a fundamental reset of Victoria’s residential construction sector. Consumer protection, professional accountability, and industry transparency are now front and centre, with significant implications for how developers, builders and regulators interact.

But this is more than regulatory housekeeping, it’s a rebalancing of risk and responsibility across the entire supply chain. Builders are being asked to operate more like professionals than tradespeople. Developers must budget not just for construction but for compliance and regulators will no longer sit back and wait for failure before stepping in.

Those who treat these reforms as a compliance box-tick will struggle. Those who understand them as strategic levers (for reputational strength, investor confidence, and client trust) will be better placed to thrive in the new building industry order.

Early preparation, sound contractual practices and a business-wide understanding of these new obligations will be essential. The rules have changed. Now is the time to reset your processes, rethink your risk and reframe your position in Victoria’s evolving construction landscape.
