Applications for all post consent certificates are available in the NSW Planning Portal. Once you have development consent for building work, you will need to obtain a Construction Certificate.
Generally, you should lodge your Construction Certificate after you have received development consent. However, if your proposal is straightforward or small-scale, you can lodge a DA and CC at the same time.
After applying for a Post Consent Certificate in the Portal, you will be prompted to select the certificate you need. If you agree for Lake Mac to be your principal certifier, you will need to nominate 'Lake Macquarie City Council'.
If you would like Lake Macquarie City Council to complete all the certification work for the development, you will need to appoint 'Lake Macquarie City Council' as the Principal Certifier in the NSW Planning Portal.
