BASIX and planning approvals

The BASIX requirements are an integral part of the development application process in NSW. Once the design plans are complete, follow the steps below:

Obtain a BASIX certificate

  • Complete the BASIX assessment.
  • Once you have met all the targets, generate a certificate and pay the fee.

Submit your application

  • Submit your development application or complying development application with the BASIX certificate attached. If you make any changes to your project, you must revise the BASIX assessment and print another certificate and re-lodge it at council. 
  • There is no charge to revise a valid certificate lodged with the consent authority.

Assessing your application

  • Council will then assess your application, and if approved, it must be built according to the BASIX commitments.
  • The construction process will be inspected by a certifying authority.

Construction certificate

  • You will need a construction certificate before the build begins.
  • Attach the BASIX certificate to the application for a construction certificate and ensure all BASIX commitments are shown on the plans.

Occupation certificate

  • Attach the BASIX certificate to the application for an occupation certificate.
  • The certifying authority will only issue a final occupation certificate when satisfied that the project has been built as described on the BASIX certificate.

Completion receipt

  • Following the final inspection and prior to issuing a final occupation certificate, the certifying authority is required to issue a BASIX completion receipt.
