Choosing a building certifier (Queensland)
Your certifier is the person who assesses the building application, inspects key stages, and issues final certification paperwork.
General info only — confirm requirements for your project/classification.
What a certifier does in QLD
QBCC describes building certifiers as licensed professionals who assess building applications, decide whether to issue building approvals, and inspect/certify building works.
- Review design/engineering evidence for compliance
- Set inspection stages and issue inspection certificates
- Issue final inspection / occupancy-related outcomes (project-dependent)
Key QLD paperwork you’ll see
- Form 16 — inspection certificate used for stage inspections (commonly referenced in QLD guidance).
- Form 21 — final inspection certificate for single detached class 1a / class 10 (where applicable).
- Certificate of occupancy may apply depending on building/classification; QLD business guidance explains certifier documentation and related steps.
Practical tip
Ask your certifier upfront: “What exact forms and evidence will you require at each inspection stage?”
What to ask before you appoint one
- What are your mandatory inspection stages for this type of build?
- How much notice do you typically need to book each stage?
- What evidence do you want from trades (certificates, photos, test results)?
- What happens if we need a variation — what do you need to approve it?
