Knock Down Rebuild Council Approvals
Council approvals are a critical part of any knock down rebuild. This guide explains the approval process, what you need, and how to navigate it efficiently.
Every knock down rebuild in Australia requires council approval. Understanding the process helps you plan your timeline and avoid delays.
The Three Key Approvals
1. Demolition Permit
Before the existing home can be removed, you need a demolition permit from your local council. This ensures:
- Safe removal of hazardous materials (asbestos, lead)
- Proper utility disconnections
- Site management during demolition
- Waste disposal compliance
2. Development / Planning Approval
Your new home must be approved by council or a planning authority. The type of approval depends on your state:
| State | Fast-Track | Full Assessment |
|---|---|---|
| NSW | Complying Development Certificate (CDC) | Development Application (DA) |
| QLD | Complying development | Development Application |
| VIC | Not applicable (building permit only, if no overlay) | Planning permit |
| SA | Deemed-to-satisfy | Development Application |
| WA | Not applicable | Development approval |
| TAS | Not applicable | Planning permit |
| ACT | Not applicable | Development application |
| NT | Not applicable | Development permit |
3. Building / Construction Approval
Before construction begins, a building certifier or surveyor must approve the construction plans, confirming compliance with the National Construction Code (NCC) and Building Code of Australia (BCA).
What Council Assesses
Your local council will assess the proposed new home against:
- Zoning — what's permitted on your block
- Setbacks — distance from boundaries
- Height limits — maximum building height
- Site coverage — percentage of the block covered by the building
- Overlays — heritage, environmental, bushfire, flood
- Neighbour impact — overlooking, overshadowing, visual bulk
- Parking — required car spaces and access
How Long Do Approvals Take?
| Approval Type | Typical Timeframe |
|---|---|
| Demolition permit | 1–4 weeks |
| Fast-track (CDC/complying) | 2–4 weeks |
| Full DA / planning permit | 6–16 weeks |
| Building certification | 2–4 weeks |
Tips for a Smooth Approval Process
- Use a builder who manages approvals — many KDR builders handle the entire process
- Check for overlays early — heritage or environmental overlays can block demolition
- Talk to neighbours — objections can delay approvals
- Choose a standard design — custom designs that push boundaries take longer to approve
- Have all documents ready — complete applications are processed faster
