Course Overview
What is the Restricted Kitchen, Bathroom and Laundry Builder Licence?
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. 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 are the contractor-facing units — safety, contracts, estimating, materials procurement, site administration, legal obligations and business finances. That mix is deliberate: this licence is about carrying the commercial and legal weight of a renovation contract, because the trade skill is assumed to be already in your hands.
One important thing to know before you enrol. These 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, and you can present it to QBCC for either class — or both. If outdoor structures, retaining walls and paving are also part of your work, read our structural landscaping page before deciding which licence to apply for.
