Builder registration classes in Victoria

What VBA registration is

Building practitioner registration in Victoria is the licensing system that controls who can carry out domestic building work. It is administered by the Victorian Building Authority (VBA), the state regulator established under the Building Act 1993 (Vic).

From 1 July 2025 the VBA was reorganised into the Building and Plumbing Commission (BPC). The legal framework, registration categories and obligations did not change with the rename. References to the VBA in legislation and existing registration certificates remain valid.

For a Victorian residential builder, registration is the legal prerequisite to entering any major domestic building contract.

The legal framework

Part 11 of the Building Act 1993 (Vic) and the Building Regulations 2018 (Vic) establish the registration framework. The Act sets out the categories and classes of registration; the Regulations prescribe the detail of each.

Registration is required to:

• Enter a major domestic building contract (over $10,000 incl GST) as a builder
• Carry out domestic building work for another person above the threshold
• Supervise domestic building work above the threshold
• Hold yourself out as available to do registered building practitioner work

Doing registered work without registration is an offence under the Building Act, with substantial penalties.

The $10,000 threshold for major domestic building contracts

Domestic building work in Victoria above $10,000 incl GST is a major domestic building contract under the Domestic Building Contracts Act 1995 (Vic). A builder must be registered before entering one.

Below $10,000, registration is not required (the work can be done by an unregistered person) although the statutory warranties under section 8 of the DBCA still apply to any contract performed.

The Victorian threshold ($10,000) sits between the NSW thresholds. NSW has a licensing threshold at $5,000 incl GST and a separate major-contract threshold at $20,000 incl GST. Victoria collapses both into a single $10,000 threshold.

Domestic Builder (Unlimited) vs (Limited)

Two registration classes cover most residential building work.

Domestic Builder (Unlimited) authorises the holder to carry out, manage or arrange all classes of domestic building work. This is the standard registration for a general residential builder taking on full new builds and major renovations.

Domestic Builder (Limited) authorises only specific types of domestic building work, such as carpentry, glazing, kitchen and bathroom renovations or other defined scopes. The Limited categories suit specialist contractors who do not need full general registration. Each Limited category has its own scope of work specified in the Regulations.

The VBA also accepts Domestic Builder (Unlimited) applications with conditions that restrict the scope of works. This lets applicants choose a level of registration that matches their competencies and experience.

Other building practitioner categories

Beyond Domestic Builder, the Building Act registration framework includes commercial builder classes (Unlimited and Limited) for non-residential construction, demolisher, erector or supervisor of temporary structures, building surveyor (the certifier role), building inspector and quantity surveyor.

Specialist trade work (electrical, plumbing, gasfitting) is licensed under separate regimes administered by Energy Safe Victoria and the plumbing function within VBA/BPC. These are not covered under the building practitioner registration framework.

Registration eligibility

To apply for Domestic Builder (Unlimited) registration, an applicant must demonstrate relevant qualifications (typically a Certificate IV in Building and Construction or higher), practical experience under a registered builder (the years required depend on the qualification path), knowledge of the Building Act, the National Construction Code and contract law (assessed by interview or assessment), financial capacity to operate as a builder (no current insolvency or bankruptcy) and good character (no recent serious offences).

Domestic Builder (Limited) registrations have lower thresholds: less broad experience requirements and qualifications tailored to the specific category being applied for.

Registration for building companies

Companies engaged in domestic building work in Victoria must have a registered building practitioner serving as their nominated representative (sometimes called the Builder Manager or Nominated Manager). The manager is personally responsible for the building work the company undertakes and must hold the relevant registration class for the work.

A company without a registered Nominated Manager cannot enter major domestic building contracts in its own name. If the manager leaves, the company must replace them or stop taking on new work above the $10,000 threshold.

Comparison to NSW Fair Trading contractor licence

The structural differences between VIC registration and NSW licensing matter for builders working across both states.

Victoria has a single registration scheme administered by VBA/BPC. NSW has a contractor licence administered by NSW Fair Trading and overseen by the NSW Building Commissioner.

Victoria requires registration above $10,000 incl GST. NSW requires a licence above $5,000 incl GST.

Victoria operates two main classes (Domestic Builder Unlimited and Limited). NSW operates a category system (general building, specialist trades, supervisor certificates) under the Home Building Act 1989.

A builder operating in both states must register in each. Mutual recognition under the Mutual Recognition Act 1992 (Cth) speeds the process where the applicant already holds a substantively equivalent registration interstate.

Practical implications

For Victorian residential builders, three things follow from the registration framework.

Maintain registration actively. VBA registration must be renewed periodically (typically annually) with payment of the renewal fee and confirmation of continuing eligibility (financial position, claims history). A lapsed registration stops the builder from entering major domestic building contracts immediately.

Match registration to scope. A Domestic Builder (Limited) class only authorises work within its defined scope. Taking on work outside the scope risks both contract enforceability and VBA enforcement action.

Keep CPD current. The Building Act and Regulations specify Continuing Professional Development requirements as part of registration renewal. Failure to complete CPD is a renewal blocker.
