This guide concerns domestic building trades. Plumbing and electrical work have separate registration and licensing systems, so it is not a statement that Victorian trades are unlicensed.
A limited domestic builder class names the work
BPC lists DB-L classes for defined work such as carpentry, framing, waterproofing, bricklaying and blocklaying, and other domestic building components. The exact class determines the authorised work and application requirements.
DB-U, Domestic Builder Unlimited, covers broader domestic building responsibility and may also be issued with conditions. Compare DB-U and DB-L if you are moving from one trade into contracting full renovations or builds.
A qualification or job title alone does not tell you which class to apply for. Start with the contracts you intend to sign, then check your experience and qualification against that class.
Check whether the job needs domestic builder registration
Consumer Affairs Victoria describes the usual over-$10,000 domestic building threshold and named work that requires registration regardless of value, including reblocking, restumping, demolition and removal of a home.
It also lists exceptions for contracts involving only one specified activity. Examples include painting, plastering, wall and floor tiling, glazing, insulation and floor coverings. Combining activities can change the registration position.
For example, a painting-only contract may fall within the single-activity exception, while a contract combining plastering and painting needs a different check. Do not assume that every job done by a tradesperson sits outside domestic builder registration.
An exception does not authorise every trade
Plumbers, gasfitters and drainers have BPC registration or licensing requirements. Electricians are licensed through Energy Safe Victoria. Those systems still apply even when a contract is exempt from domestic builder registration.
Permits, safety rules and other obligations also need to be checked for the actual work. For registration thresholds and contracting arrangements, read when Victorian builder registration is needed.
Prepare for the DB-L class you actually need
Use the current BPC domestic builder class page to identify the scope. Then assemble records focused on that work:
- the domestic projects and dates relevant to the class
- the work you personally completed or supervised
- qualifications and the official transcript of units
- the registered builder who directly supervised and can verify the relevant work
- the entity that will sign contracts.
A broad résumé can hide the useful detail. If you are applying for framing, explain the framing responsibility on the selected projects rather than adding unrelated years on site.
Check BPC’s current technical-reference submission instructions before requesting or uploading reports. The format and process are changing, and the correct instructions for your class matter.

If you want to contract the whole job
Experience in one trade does not automatically establish builder-level responsibility. If you plan to coordinate all trades and contract full domestic projects, BLS can check whether the wider experience supports a DB-U application or whether a more defined class fits.
Builders Licence Success helps identify the likely registration, check qualification gaps and prepare the project and application material. BPC decides registration applications, and an RTO decides any training or RPL outcome.
Going out on your own in a domestic building trade? Start the next-step check. Tell BLS which jobs you plan to quote and the work you have already done.
