A Building Permit for Demolition is official approval from a registered building surveyor that lets you legally tear down a building or structure. It ensures the demolition is done safely, follows the law, manages waste properly, and protects people, neighbours, and the environment. You must get this permit before starting any demolition work.

1. Prepare your documents: final construction drawings, engineering, energy rating, title, and any planning permit (if required). 
2. Research and choose a registered private surveyor.
3. Lodge your application. Submit your plans and documents to the surveyor. 
4. The surveyor checks compliance with building regulations and may request changes or extra reports. 
5. Once everything complies, the surveyor issues your Building Permit, giving you legal approval to start work.
