Victorian Building Law Changes 2026: What Homeowners and Builders Need to Know

1. The BPC Transition: DBDRV and the New Regulatory Architecture

The foundational reform underpinning every other change in this post is the establishment of the Building and Plumbing Commission (BPC). Enabled by the Building Legislation Amendment (Buyer Protections) Act 2025, the BPC brings together three previously separate bodies:

• The Victorian Building Authority (VBA) — registration, licensing, enforcement and discipline;
• Domestic Building Dispute Resolution Victoria (DBDRV) — residential building dispute conciliation; and
• The domestic building insurance (DBI) function of the Victorian Managed Insurance Authority (VMIA).

Practically, this means the DBDRV no longer operates as a standalone entity. Dispute resolution services that were previously administered by the DBDRV are now provided by the BPC. If you have a domestic building dispute — defective work, incomplete construction, contract disputes — the BPC is now your single point of entry before any referral to VCAT.

Implications for Homeowners

The BPC's new rectification order power is the most significant consumer protection introduced under the Buyer Protections Act 2025. Previously, homeowners had to wait until a builder became insolvent, disappeared or died before making a domestic building insurance claim. Under the new regime, the BPC can issue a rectification order against a builder after an occupancy permit is issued — directly addressing the common scenario where defects only become apparent once a homeowner moves in. If a builder fails to comply with such an order, domestic building insurance becomes accessible to the homeowner at that point.

Implications for Apartment Purchasers

For apartment buildings of more than three storeys, developers must now notify the BPC before the building is occupied, enabling the regulator to conduct a final inspection. A developer bond (set at 2% of the build cost) is also required for mid- to high-rise apartment buildings, effective from 1 July 2026. This bond remains available for two years post-completion to fund defect rectification if the developer or builder fails to act. Purchasers of off-the-plan apartments should confirm bond lodgement as a condition of settlement from that date.

2. Faster, Better Licensing and Registration

On 6 February 2026, the BPC announced a comprehensive overhaul of its accreditation processes for building and plumbing practitioners. This follows years of industry complaints about excessive wait times and opaque assessment criteria. The key changes, now live for Domestic Builder Unlimited (DBU) applicants and rolling out across all licence classes through 2026, are:

• Face-to-face interviews abolished. The traditional panel-style technical interview is gone. Practitioners no longer need to attend in person for what were often described as high-pressure, inconsistently administered assessments.
• Scheduled exams replaced with on-demand online testing. Examinations are now administered online, 24 hours a day, using proctoring software and dynamic question sets developed in partnership with the Australian Council for Educational Research (ACER). Applicants choose when and where to sit, subject to their availability.
• Reduced documentation burden. The volume of supporting documents required has been significantly reduced, with the BPC targeting a more proportionate, evidence-based approach.
• Risk-based assessment model. Applications are now assessed through a tiered risk framework: high-risk applications (those lacking sufficient experience documentation or with compliance history concerns) receive standard scrutiny; low-risk applications are fast-tracked. Where an application clearly does not meet requirements, an early determination is made, avoiding prolonged delays for applicants who need to address deficiencies.

Rollout Timetable

The changes are presently confirmed for DBU applicants. Throughout 2026, they will phase in for:

• Commercial Builder (Unlimited and Limited)
• Domestic Builder Limited (all trade categories, including carpentry, bricklaying, and waterproofing)
• Demolisher classes
• Building Designers and Building Inspectors

Practical Significance

Practitioners whose registration applications have stalled — including those who have completed training but have been waiting months for an interview date — should revisit their applications under the new model. Where a delay has caused business or contractual loss, we can assist in assessing whether regulatory delay created actionable consequences.

3. Proposed Minimum Financial Requirements for Domestic Builders

Published in the Victorian Government Gazette (Special Gazette No. S054) on 4 February 2026, the proposed Building Amendment (Minimum Financial Requirements) Regulations 2026 represent the most significant structural reform to builder financial oversight in Victoria's recent history. Public consultation was open through 18 March 2026, with final regulations expected in April 2026 and commencement from 1 July 2026.

These regulations implement a core pillar of the Building Amendment (Buyer Protections) Act 2025: transferring financial suitability oversight from private domestic building insurers to the BPC, as a condition of registration.

The Three-Tier System

All domestic builders will be classified into one of three tiers based on their Net Tangible Assets (NTA):

Important: New entrants and existing builders seeking to increase their approved activity beyond current limits must comply with MFR requirements from 1 July 2026, regardless of these transitional dates. Grandfathering protections apply only to those holding a current letter of eligibility for domestic building insurance at commencement.

Core Financial Tests

All registered domestic builders must satisfy three ongoing obligations:

1. Solvency: Ability to pay debts as and when they fall due. A debt is not considered "due" until any genuine dispute or offsetting claim is legally resolved.
2. Current ratio ≥ 1: Current assets must equal or exceed current liabilities at all times — not merely at annual reporting dates. This is a continuous compliance obligation. Certain assets are disallowed from the calculation, including loans receivable from related entities (unless current assets are sufficient to repay those loans in full) and non-listed company shares or trust units.
3. Revenue cap: Annual revenue must not exceed 20 times the builder's NTA. Builders must notify the BPC at least seven business days before exceeding their revenue cap, lodging either a financial declaration (if revenue is under $1 million) or a full MFR report (if revenue is $1 million or more).

Reporting Obligations

Annual reporting scales by tier:

• Tier 1: A signed financial declaration confirming NTA, current ratio, and revenue compliance. No independent accountant required.
• Tier 2: Internal management accounts prepared in accordance with applicable Australian Accounting Standards, with disclosures on aged debtors and creditors upon request.
• Tier 3: Full financial statements prepared to Australian Accounting Standards, with director sign-off. Where a builder already lodges audited general purpose financial reports with ASIC, those reports may satisfy this requirement.

All registered domestic builders must prepare internal management accounts quarterly as a condition of registration, regardless of tier. These must be provided to the BPC within 14 business days of a written request.

Notification Triggers

What Builders Should Do Now

The consultation period has closed and regulations are on track for finalisation in April 2026. Builders should:

• Calculate NTA using the regulatory definitions, not standard accounting conventions — the two can differ materially given disallowed assets;
• Identify where trust structures will reduce NTA over the four-year depreciation schedule;
• Assess whether their current revenue would exceed the 20× NTA cap and take early steps to address any shortfall;
• Establish quarterly management account processes now, even ahead of their formal compliance date; and
• Engage an independent, qualified accountant (CPA Australia, Chartered Accountants ANZ, or IPA member) who is not connected to the building entity.

Implications for Homeowners

These regulations directly protect residential clients. A builder who cannot maintain a current ratio of 1 or satisfy the solvency test presents a financial risk that may materialise as incomplete or defective work. From 1 July 2026, you can request confirmation from any prospective domestic builder that they meet their applicable MFR tier requirements. If a builder's registration is at risk due to MFR non-compliance, that is a critical factor in any contract decision.

4. BAMS Building Permit Number Field Changes (From 20 March 2026)

From 20 March 2026, the BPC is implementing a series of updates to the Building Activity Management System (BAMS) — the system used by relevant building surveyors and permit authorities to record and track building permits across Victoria. These changes affect the fields associated with the Building Permit Number (BPN) and are driven by recent legislative amendments and a push for improved inspection data.

Cost of Work Field Renaming

All fields referencing "Estimated Cost of Works" are being renamed to remove the word "Estimated", reflecting the updated statutory method for calculating the cost of building work. This is more than a labelling change: it signals that cost-of-work figures recorded in BAMS are now treated as the operative figures for levy and regulatory purposes, not preliminary estimates. Building surveyors, permit authorities, and builders involved in BPN applications should review their workflows accordingly.

Key renamed fields include:

• Estimated Cost of Works For This Permit → Cost of Works For This Permit
• Total Estimated Cost of Works → Total Project Cost of Works
• Total Estimated COW – Class 2 to 8 → Total Project COW – Class 2 to 8
• Total Estimated COW – Class 1 or 9 or 10 → Total Project COW – Class 1 or 9 or 10
• Number of Storeys → Rise in Storeys

New Mandatory and Optional Fields

Three new fields are being introduced:

• Storeys Contained (optional): Records all storeys within the building regardless of their position relative to ground level. This differs from "Rise in Storeys", which counts only storeys contributing to the building's rise above ground — a distinction material for class determinations and certain levy calculations.
• Is the Builder an Architect (mandatory): Permit applicants must nominate whether the nominated builder holds registration as an architect. This enables BAMS to validate builder registrations more accurately and will affect how builder credentials are cross-referenced against the BPC register.
• Builder Email (optional): Supports builder validation and matching in BAMS.

Certificate of Consent and Builder Registration Updates

The necessity conditions for several existing fields are being tightened:

• The Is Certificate of Consent Required? field will only appear if the Owner Builder Indicator is set to "Y".
• The Certificate of Consent Number field becomes required whenever a Certificate of Consent is indicated as required.
• Builder Registration Number field conditions are also being updated.

Building surveyors and permit authorities using BAMS API integrations should note that updated technical specifications have been published on the BAMS webpage and must be incorporated into any automated permit lodgement systems before 20 March 2026.

Residential vs Commercial: Different Impact

For residential projects (Class 1 and Class 10), the COW renaming directly affects levy calculations and the documentation builders provide at permit stage. Any disputes about levy quantum will now reference the renamed field as the operative figure. For commercial projects (Class 2 to 8), the renaming of Class 2–8 COW fields and the new "Storeys Contained" field will affect high-rise classification determinations, which in turn affect mandatory notification obligations under the BPC's new pre-occupation inspection powers.

5. Construction Enforcement Victoria Bill 2026: Defeated, but Significant

On 4 March 2026, the Victorian Legislative Assembly debated the Construction Enforcement Victoria Bill 2026, introduced by the Member for Sandringham, Brad Rowswell (Opposition). The bill sought to establish an independent statutory office — the Head, Construction Enforcement Victoria — to monitor compliance with the Construction Industry Code on Victorian government construction and development projects.

What the Bill Proposed

The bill drew directly from the code enforcement model that operated under the Baillieu–Napthine Coalition governments (and that had existed in a related form at the federal level through the Australian Building and Construction Commission, which was abolished by the federal Labor government). Key proposed features included:

• An independent Head of Construction Enforcement Victoria with broad investigative powers on government construction sites;
• A mandatory referral obligation: allegations of criminal activity to Victoria Police or WorkSafe; corruption allegations to IBAC;
• Power to issue banning orders against individuals or entities found non-compliant with the Construction Industry Code; and
• Reporting obligations designed to provide transparency over the $213 billion capital program currently being delivered by the Victorian Government.

The Vote

The motion to introduce the bill was defeated 51 votes to 31. The government benches, led by the Allan Labor government, opposed the bill on the grounds that existing mechanisms — including Operation Hawk (which has resulted in nearly 70 charges), the Labour Hire Authority (which has cancelled 126 licences), and an established complaints referral service — were sufficient.

Why This Matters Regardless of Outcome

The bill's defeat does not diminish its significance for the building sector. The parliamentary debate confirms that enforcement of the Construction Industry Code on government worksites remains actively contested political terrain. For contractors working on government construction projects in Victoria, the debate signals:

• Heightened regulatory and law enforcement scrutiny is ongoing on government construction sites;
• IBAC referrals and Victoria Police engagement with construction site conduct are increasing in volume; and
• The code compliance framework will be a central issue at the next state election.

Contractors, subcontractors, and labour hire operators on government projects should ensure their compliance with the Building and Construction Industry (Improving Productivity) Act 2016 (Cth) framework and applicable state codes. Compliance failures in this environment carry reputational and contractual risk well beyond any formal enforcement action.

6. Security of Payment: New Power to Void Unfair Time Bars

A further reform — not one of the four primary subjects of this post, but directly relevant to Victorian building practitioners — is the pending commencement of Part 2 of the Building Legislation Amendment (Fairer Payments on Jobsites and Other Matters) Act 2025, which amends the Building and Construction Industry Security of Payment Act 2002 (Vic) (SOP Act). Royal Assent was received on 13 November 2025; proclamation is expected in early to mid-2026 and no later than 1 September 2026.

The centrepiece amendment introduces a new section 13A into the SOP Act, empowering adjudicators, courts, arbitrators, and expert determiners to declare a "notice-based time bar" in a construction contract unfair, and void it for the purposes of the particular dispute at hand, where compliance is not reasonably possible or would be unreasonably onerous.

Key Features

• A "notice-based time bar" includes any provision making entitlement to payment, an extension of time, or release of performance security contingent on provision of a notice within a specified timeframe;
• The reforms apply retrospectively to existing contracts;
• The onus of proving unfairness falls on the party seeking to avoid the time bar (almost always the claimant);
• A voided time bar is voided for that dispute only — the clause is not permanently deleted from the contract; and
• Factors the determiner must weigh include relative bargaining power, when the party would reasonably have known of the deadline, and the nature of the notice requirement itself.

Practical Implications

For subcontractors and claimants: time-barred claims that were previously considered dead may be revivable under the amended SOP Act. Legal advice should be sought before treating any time bar as final. For head contractors and upstream parties: expect an increase in previously time-barred claims and review your contract administration to ensure time bars are enforced consistently — inconsistent application risks waiver and estoppel arguments.

7. What This Means for You

For Homeowners and Owner-Builders

• The BPC is now the single point of contact for domestic building disputes previously handled by the DBDRV. Conciliation through the BPC remains a mandatory step before VCAT in most residential building disputes.
• The new rectification order power means the regulator can intervene against a non-compliant builder after your occupancy permit is issued — no longer must you wait for insolvency.
• From 1 July 2026, confirm your builder's MFR compliance tier before signing any domestic building contract. A builder operating close to or in breach of their tier obligations is a financial risk to your project.
• For off-the-plan apartment purchases of buildings above three storeys, request confirmation of the developer bond lodgement from 1 July 2026.

For Registered Domestic Builders

• Licence renewals and new applications under the modernised accreditation model should be faster; however, the portfolio and examination requirements remain substantive. Applications require careful preparation despite the removal of interviews.
• Begin MFR preparation now, regardless of your transitional compliance date. New entrants and builders increasing activity must comply from 1 July 2026 without exception.
• Review trust structures, intercompany loans, and related-entity arrangements against the MFR disallowed assets definitions — many builders will find their effective NTA is lower than their balance sheet suggests under standard accounting treatment.
• Update internal BAMS workflows before 20 March 2026 to reflect the renamed COW fields and the new mandatory "Is the Builder an Architect" field.

For Commercial Contractors and Government Project Participants

• The Construction Enforcement Victoria Bill was defeated, but the regulatory and law enforcement environment on government construction projects is materially more intense than in prior years. Compliance programmes and document preservation are essential.
• Prepare for proclamation of the amended SOP Act Part 2 at any time from early 2026. Review all active contracts to identify time bars that may now be susceptible to challenge and audit the consistency of your own time bar enforcement practices.
• The "Storeys Contained" and "Rise in Storeys" BAMS distinction carries significance for Class 2–8 buildings in respect of pre-occupation notification obligations and levy calculations.
