Renovating wet areas is one of the busiest corners of Queensland residential construction, and one of the most tightly regulated. Any residential building work over $3,300 needs a QBCC licence held by the person contracting for it. That is why so many capable bathroom and kitchen renovators end up working under a builder's licence that is not their own, taking a subcontractor's rate on work they scoped, priced and ran themselves.
The builder restricted to kitchen, bathroom and laundry licence exists so you do not have to. It is a QBCC builder licence with the scope trimmed to the work you already do. QBCC's scope for the class is to install, refurbish, restore and repair a kitchen, bathroom or laundry on-site in a class 1 or class 10 building, and in classes 2 to 9 buildings where the gross floor area of that kitchen, bathroom or laundry is not more than 50m². In practice that is the whole wet-area job under one contract: strip-out, wet-area framing and lining, waterproofing, wall and floor tiling, cabinetry and benchtop installation, and the plumbing and electrical fit-off that goes with it, each trade holding whatever licence QBCC requires for its own work. It does not extend to work affecting structural performance.
The technical qualification for the class is seven units of competency from CPC40120, not the full nineteen-unit Certificate IV. They cover the contract side of a renovation. Safety in a stripped bathroom with live services. The renovation contract itself, including variations when the demolition uncovers rot or old asbestos sheeting. Estimating tiling, waterproofing and joinery quantities. Procuring long-lead cabinetry, stone and fixtures against a tight programme. Site administration across five or six trades in a small room. The legal obligations of a licensed contractor, and the finances of a renovation business. The trade skill is assumed to be already in your hands. What the licence adds is the right to carry the contract.
One thing to know before you enrol. The same seven units are also the technical qualification for the QBCC builder restricted to structural landscaping licence. You complete one course and one Statement of Attainment. You can present it to QBCC for either class, or both. Most wet-area renovators only ever need this class. If retaining walls, decks or paving are also part of your work, read our structural landscaping page before deciding which licence to apply for.
Recognition of Prior Learning (RPL) involves an assessor reviewing your current skills and evidence against the units in the Builder restricted to kitchen, bathroom and laundry (QLD). You may need further evidence or gap training. Experience alone does not establish competency, and no fixed reduction in study time is guaranteed.
QBCC specifies seven units from CPC40120 for this licence class — three core units and four electives. They are the contractor-facing units: contracts, costs, materials, safety, legal obligations and business finances.
Tradespeople already doing wet-area renovation work in Queensland who want to hold the contract instead of working under someone else's builder licence.
Renovators running complete bathroom strip-outs and rebuilds who currently need a licensed builder to sign the contract.
Joinery businesses that want to contract the whole kitchen renovation rather than supply and install only.
Wet-area specialists who are already scoping and coordinating the other trades on a job and want the licence to match.
Licensed plumbers whose customers keep asking for the whole bathroom, not just the plumbing.
Operators who want a nominee supervisor qualification in-house instead of hiring the licence from outside.
This restricted licence package is drawn from the CPC40120 Certificate IV in Building and Construction. This overview covers what the full qualification involves and how the units apply to residential building and renovation work.
Wet-area renovation is repeat, referral-driven work with strong margins for the person holding the contract. This licence moves you from priced-by-the-day subcontractor to the contractor who owns the job, the client relationship and the margin.
Contracting complete bathroom strip-outs and rebuilds directly with homeowners, coordinating waterproofers, tilers, plumbers and electricians.
$95,000 – $150,000Running kitchen refurbishments end to end — demolition, services rough-in, joinery installation, benchtops and finishing.
$100,000 – $160,000Operating your own licensed wet-area renovation business, employing trades and running several jobs concurrently.
$110,000 – $180,000Acting as the nominee supervisor for a renovation company's QBCC licence, carrying technical responsibility for its work.
$100,000 – $140,000Joinery and cabinetmaking businesses that want to contract the whole kitchen rather than supply and install only.
$90,000 – $140,000Scheduling and coordinating multiple wet-area renovations for a volume renovation or insurance repair company.
$90,000 – $130,000These roles are in high demand across Australia and offer strong earning potential.

Licensed builders operating their own businesses have uncapped earning potential based on the volume and value of projects they deliver.

Quote, sign and invoice the homeowner directly instead of taking a subcontractor rate under someone else's builder licence
The QBCC technical requirement for this class is a subset of CPC40120 — a fraction of the study time of a full builder licence
The identical unit set is also the technical qualification for the structural landscaping class, so nothing is wasted if your work broadens
Every unit carries full credit if you later go on for the complete Certificate IV and an unrestricted low-rise builder licence
