What Is a Building Permit?
A building permit (called a construction certificate in NSW or a building approval in some jurisdictions) is a formal authorisation that must be obtained before commencing most building, renovation, or demolition work. It confirms that the proposed work complies with the National Construction Code, relevant Australian Standards, and any local planning requirements.
When You Need One
Most structural work requires a building permit, including new builds, extensions, carports, retaining walls over a certain height, swimming pools, and significant renovations. Minor work such as painting, replacing like-for-like fixtures, or garden landscaping typically does not require a permit, though rules vary by council and state.
Your builder or architect usually applies for the permit on your behalf. The application includes architectural plans, engineering specifications, energy efficiency reports, and evidence that the proposed work meets fire safety and accessibility requirements.

How It Relates to Licence Verification
A building permit is only valid when the work is carried out by licensed professionals. If you hire an unlicensed builder, the permit can be voided and the certifier may refuse to issue a final compliance certificate. Using TradieVerify to verify your builder’s licence before work begins protects both the validity of your permit and the safety of the finished structure.
