What is a building permit?

In Australia, a building permit sits downstream of planning approval. Once a council approves your development application and planning permission, you then need a building permit (often called a construction certificate) to legally begin work on site. This is a separate document and distinct approval process.

The local council or an accredited private certifier issues the building permit after checking your plans and specifications against the National Construction the team. The certifier verifies that your proposed construction meets structural safety requirements, fire safety standards, accessibility rules, energy efficiency codes, and other mandatory standards. This is not about whether the building fits the neighbourhood character or planning zone; that was settled at the planning stage.

For custom home builders, the building permit is essential because work cannot legally start without it. Banks and insurers expect it. Inspectors use it to know what was approved when they visit the site during construction. If you build without a valid permit, councils can issue stop work orders or require removal of unauthorised work.

The issuing authority is your local council in most cases, though larger projects and some renovation work can go to an accredited private certifier approved by the state. Either way, the permit proves that an independent party has reviewed your design for safety and code compliance before construction begins.
