Form 12
Do You Actually Need a Form 12?
A Form 12 is typically required when:
✔ Structural works have been completed
✔ A certifier requires inspection confirmation
✔ Retaining walls, slabs or structural elements need sign-off
✔ Construction stages must be certified before continuation
If you’re unsure — that’s normal. Many clients contact us simply to confirm whether a Form 12 applies to their project.

A Form 12 Certificate is required in Queensland when a building certifier needs confirmation that construction work has been completed in accordance with the approved plans and relevant Codes. It is often used for inspections of structural works, uncertified building elements, or upgrades such as reroofing, extensions and repairs.
