Development Applications
Whether it’s a major project, a new house, or an extension, you need to know the rules if you are going to build on your property.
Find information about the Development Application process and helpful links.
Do I need a development application?
A Development Application (DA) is an application for development that requires consent under the NSW Environmental Planning and Assessment Act 1979 (EP&A Act).
If your development project doesn’t meet the rules for Exempt Development or Complying Development you will need to lodge a DA with us to obtain approval (also known as development consent).
To obtain development consent, lodge your DA with us via the NSW Planning Portal.
If construction works are a part of your development, you will need a Construction Certificate. You can apply for a Construction Certificate at the same time as your DA or after the DA has been approved.
