Thinking about extending your home is exciting, but before the first hammer swings, there is a fair bit of paperwork to clear. In New South Wales, the permit process ensures your new space is safe, structural, and doesn’t upset the neighbours.
Navigating Council requirements can feel like a headache but getting it right at the start saves you from massive fines or being forced to tear down the work later. Here is a breakdown of what you need to get moving.
Development Application (DA) or Complying Development (CDC)?
Most people start by asking if they need a DA. A Development Application is a formal request to your local Council to carry out a project. This is usually required if your extension is large, changes the look of the street, or is on a tricky block of land.
However, many homeowners can use a Complying Development Certificate (CDC) instead. This is a faster, 20-day approval process for straightforward builds that meet specific state-wide standards. If your project ticks all the boxes for height, size, and distance from boundaries, a CDC is often the quickest path to starting your home renovations and extensions.
Construction Certificate (CC)
If you went down the DA route with Council, you aren’t finished yet. You still need a Construction Certificate. While the DA approves the concept of the extension, the CC approves the technical side. It proves that your building plans and scales meet the Building Code of Australia. You can get this from Council or a private certifier.
Section 68 Approval
If your extension involves plumbing or drainage work that connects to the Council’s water or sewer mains, you might need a Section 68 approval. This is common if you are adding a second storey with a new bathroom or shifting your kitchen to a new part of the house.
Home Building Compensation (HBC) Cover
In NSW, if your residential building work is valued at over $20,000, your builder must have HBC cover (formerly known as Home Warranty Insurance). This protects you if the builder can’t finish the job or fix defects. Never start an extension without seeing a copy of this certificate first.
Why the right advice matters
Every block of land in Sydney is different. You might have heritage overlays, bushfire risks, or even underground pipes that restrict where you can build.
