QBCC Licensing & Domestic Building Contracts
Statutory guide to contracting residential building work in Queensland. Review Australia's lowest trade licence threshold ($3,300), the mandatory Queensland Home Warranty Scheme, and statutory deposit caps.
$3,300 Statutory Licence Threshold
Section 42, QBCC Act 1991
In Queensland, any building work, structural landscaping, retaining wall, concrete driveway, or fencing project valued over $3,300 (incl. labor, materials, and GST) requires an active QBCC contractor licence. Specialist trades (plumbing, drainage, electrical) require a licence regardless of value ($0 threshold).
$3,300 Home Warranty Premium Trigger
Queensland Home Warranty Scheme
Unlike NSW ($20k) and VIC ($16k), Queensland requires mandatory insurance coverage for any residential construction exceeding $3,300. The contractor must pay the premium to QBCC within 10 business days of signing the contract or before work starts.
Queensland Statutory Deposit Limits
Regulated under Schedule 1B of the QBCC Act 1991. Strict percentage caps dictate the maximum deposit a builder can legally request prior to work starting.
Contracts Under $20,000
Maximum statutory deposit is capped at 10% of the total contract price.
Contracts $20,000 and Over
Maximum statutory deposit is capped at 5% of the total contract price.
Custom Off-Site Fabrication
If more than 50% of the contract value is fabricated off-site (e.g., custom structural steel, cabinetry), the maximum deposit is 20%.
Key QBCC Licence Classes
Contractors must hold the exact licence class corresponding to your scope of works.
Builder – Low Rise / Medium Rise
Authorised to carry out or supervise all building work on Class 1 and Class 10 buildings (houses, townhouses, sheds, retaining walls) up to 2 storeys (Low Rise) or 3 storeys (Medium Rise).
Structural Landscaping
Authorised for residential external works: retaining walls of any material, concrete paving, timber decks, pergolas, fences, drainage, and related structural elements.
Carpentry / Concreting / Bricklaying
Restricted to the specific trade discipline. A concreter or carpenter cannot contract to manage other trades unless holding a Builder or Structural Landscaping licence.
QLeave Portable Long Service Leave
For any building work in Queensland valued at $150,000 or more (excl. GST), a statutory QLeave levy of 0.575% must be paid prior to local council or certifier issuing building approval.
Queensland Home Warranty Scheme Details
A statutory insurance policy managed directly by the QBCC, protecting homeowners if a contractor dies, disappears, becomes insolvent, or fails to rectify structural defects.
Statutory Coverage Limits
Provides coverage up to $200,000 (which can be optionally upgraded to $300,000) for incomplete work, structural failure, loss of deposit, and post-completion subsidence.
Warranty Defect Periods
- Primary / Structural Defects: 6 years and 6 months from date of payment or contract execution
- Non-Structural / Cosmetic Defects: 6 months from practical completion
Consumer Action Protocol
- Never pay the deposit until reviewing the written contract
- Verify the contractor holds an active QBCC licence online
- Ensure you receive the QBCC Confirmation of Insurance Certificate
Consumer Rights & Dispute Escalation
5-Business-Day Cooling-Off Period
Under Schedule 1B of the QBCC Act, homeowners have 5 business days to withdraw from a domestic building contract over $3,300 after receiving a signed copy. A statutory fee of $100 plus out-of-pocket costs incurred by the builder may apply if withdrawn.
QBCC Early Dispute Resolution (EDR) & QCAT
For ongoing defective building work, parties must first lodge an Early Dispute Resolution (EDR) request with QBCC. If conciliation fails, disputes escalate to the Queensland Civil and Administrative Tribunal (QCAT).
