How to apply for a building permit

Most building or construction works need a building permit. It's easy to apply for a permit before you begin building.

Never start building without checking if you have the right permits.

Building permits

A building permit is a legal document. It shows a building surveyor has approved all documents for proposed construction work.

Building permits assess and ensure standards for the construction and maintenance of buildings.

The Building Act 1993 and Building Regulations 2018 require that most building works need a building permit. This includes most:

  • alterations
  • demolitions
  • removals.

Beginning building without a building permit is a serious offence. It can result in severe penalties, such as a $82,610 fine.

In rare cases, you may not need a building permit. Before you begin:
