CDC vs DA: which approval pathway will your block take?
Two roads lead to an approved build in NSW — one takes weeks, the other months. Here's how to tell which one your project is on, before you spend a dollar.
Every home we build needs one of two approvals: a Complying Development Certificate (CDC) or a Development Application (DA). The difference is mostly time — and knowing your pathway early changes how you plan everything else.
CDC — the fast lane
A CDC is issued by a private certifier when your project ticks every box of a state-wide checklist: zoning, lot size, setbacks, height, site coverage. No neighbour notification, no council queue. Straightforward granny flats and many compact homes qualify. Typical time: 10–20 business days.
DA — the council route
If any rule can't be met — an unusual block shape, a heritage overlay, flood or bushfire mapping, or a variation you want to keep — the project goes to council as a DA. Councils weigh merit, notify neighbours and take 40–90+ days. It's not a bad outcome; it's just a longer one, and we manage it end to end.
What decides it, in practice
- Zoning and minimum lot size — the first gate
- Setbacks and building envelope — where the home can physically sit
- Bushfire (BAL) and flood mapping — may add conditions or push to DA
- Easements and sewer mains — can restrict placement
- Overlays: heritage, character areas, biodiversity
The worst approval strategy is guessing. A one-hour site assessment answers the pathway question for free.
How this fits our 8 week program
Approvals run before the build clock starts. Once your CDC or DA is issued, we lock the program: your home is built in our facility while footings and services are done on site — and handover lands 8 weeks after contract.
