VBA audits of residential builders in Victoria

What it is

The Victorian Building Authority (VBA) runs two parallel surveillance streams over registered residential builders. The Proactive Inspections Program (PIP) sends inspectors onto active building sites without invitation. The Building Documentation Audit Program does desktop reviews of permit files, contracts and certificates of compliance held by the relevant building surveyor. Both feed the same disciplinary funnel.

From 1 July 2025 the regulator was rebranded the Building and Plumbing Commission (BPC) under the Building Legislation Amendment (Buyer Protections) Act 2024, however the audit machinery, the Building Act 1993 powers and the published guidance continue to operate. For builders trading in Victoria the practical position has not changed.

What VBA audits actually check

PIP inspections target the stages where defects cluster. The 2021 to 2024 activity reports show timber framing, wet area waterproofing, external waterproofing and steel framing as the four most non-compliant items in domestic building work. Inspectors arrive at frame stage, lock-up or fixing, photograph the work, take measurements against the approved plans and check whether mandatory notification to the relevant building surveyor has occurred for the stage.

Documentation audits chase a different target. The auditor pulls the building permit file from the relevant building surveyor and tests it against the Building Act 1993, the Building Regulations 2018 and the National Construction Code in force at permit issue. Common findings include missing fire engineering reports, incomplete energy efficiency documentation, no record of mandatory inspection sign-off and gaps in the manufacturer specifications relied on for performance solutions.

Audit triggers that bring VBA to your sites

The VBA does not pick builders at random. Triggers include consumer complaints lodged through Consumer Affairs Victoria, mandatory notification failures flagged by relevant building surveyors, a pattern of insurance claims through the Domestic Building Insurance scheme, anonymous reports from subcontractors and prior disciplinary findings on the practitioner's record. A builder running multiple sites within a single municipality is statistically more likely to be sampled because PIP teams cluster inspections geographically.

The Show Cause process under section 178

When VBA forms a reasonable belief that disciplinary grounds exist the regulator issues a Show Cause notice. The notice sets out the alleged ground, the proposed action and the period for response which is at least 14 days. Section 178 of the Building Act 1993 lists the disciplinary grounds including failure to comply with the Act or Regulations, carrying out work of a standard not of the standard reasonably expected of a registered building practitioner and conduct demonstrating incompetence or insufficient experience.

The builder may respond in writing or orally. After the response period closes the Building Practitioners Disciplinary Panel has 28 days to decide. Outcomes range from no action through reprimand and conditions on registration to suspension or cancellation. Financial penalties under section 178 reach 150 penalty units per disciplinary ground for an individual and 750 penalty units per ground for a company. With the 2025 to 2026 penalty unit value at $210.07 that is a maximum exposure of $31,510 per ground for an individual and $157,552 per ground for a company.

The demerit and adverse publicity layer

VBA publishes outcomes on the Prosecution and Disciplinary Register, which is publicly searchable and indexed by Google. A finding stays on the register and feeds into the practitioner's compliance history considered at renewal under the Minister's Guideline MG-13. The 2025 suspension of Andrew Little with a $160,000 fine and the 2024 suspension of Waleed Khumra of Diamond Builders both sat on the register within days of the decision.

What this means for a TradeLens client

For builders running TradeLens the audit risk profile is identifiable. The compliance risk increases when mandatory notifications are missed, when the same defect appears across multiple Domestic Building Insurance claims and when consumer complaints sit unresolved at Consumer Affairs Victoria. TradeLens flags these as compounding signals because the VBA referral pipeline treats them as compounding signals too.

The practical defence is documentary. Builders who can produce dated photographs of every stage, signed mandatory notification forms and an audit trail of variation approvals close out PIP inspections in a single visit. Builders who cannot escalate from inspection to documentation audit to Show Cause within a single quarter.
