Development Applications in the ACT
If you're building a new home, a significant extension, or a multi-unit development in Canberra, chances are you'll need a Development Application (DA). Here's what that actually involves.
Do you need a DA?
Not always. Some projects qualify for exempt development (no approval needed) or building merit assessment (a faster, simpler process). The rules depend on your block's zone, any overlays, and what you're proposing to build.
We'll tell you which track applies before any design work begins.
The DA process, step by step
1. Pre-application advice (optional but smart) — You can request informal feedback from the planning authority before lodging. We often do this for complex sites.
2. Prepare and lodge — We prepare all drawings, reports, and supporting documents and lodge the DA on your behalf through the ACT planning portal.
3. Notification period — For most residential DAs, neighbours are notified and have 15 business days to comment. Not all DAs require notification.
4. Assessment — The planning authority reviews the application against the Territory Plan, relevant codes, and any neighbour comments. They may request additional information.
5. Decision — You receive a Notice of Decision. If approved, conditions may be attached (landscaping, materials, setbacks). If refused, there are appeal options.
How long does it take?
Statutory timeframes are 30–45 business days from lodgement, but complex applications or those requiring additional information can take longer. Our experience with Canberra planning rules helps avoid the back-and-forth that slows most applications down.
Common reasons DAs get refused
Non-compliant setbacks — the building is too close to boundaries
Overshadowing — the design casts too much shadow on neighbours
Plot ratio exceeded — too much floor area for the block size
Inadequate landscaping — not enough soft landscaping area
Every one of these is something we check before lodging. That's what "designed to get approved" actually means.
