Understanding Approval Pathways
In NSW, construction projects typically fall into one of three categories:
1. Exempt Development
- No approval needed if specific criteria are met
- Examples: small decks, fences, garden sheds under certain sizes
- Check the NSW Exempt and Complying Development Codes
2. Complying Development Certificate (CDC)
- Fast-track approval for straightforward projects
- Must meet pre-determined standards
- Issued by private certifiers or council
- Timeline: typically 10-20 days (20 days standard, 10 days for NSW Housing Pattern Book)
3. Development Application (DA)
- Required for complex or non-complying projects
- Council assesses against Local Environmental Plan (LEP) and Development Control Plan (DCP)
- Average determination time: approximately 70 days (varies by council and complexity)
- From July 2021, all DAs must be lodged via NSW Planning Portal
Step-by-Step DA Process
Step 1: Pre-lodgement
- Check zoning: Use the NSW Planning Portal Spatial Viewer to see planning constraints
- Pre-DA meeting: Optional but highly recommended
- Gather required documents (see checklist below)
- Consider engaging a town planner or architect
Step 2: Document Preparation
Required Documents:
- Completed application form
- Owner’s consent
- Statement of Environmental Effects (SEE)
- Architectural plans (site plan, floor plans, elevations, sections)
- BASIX certificate (for residential)
- BASIX/NatHERS assessment
- Bushfire assessment (if applicable)
- Flooding/Acid Sulfate Soil reports (if applicable)
- Heritage impact statement (if applicable)
- Landscape plan (if required)
Step 3: Lodgement via NSW Planning Portal
- Create an account on the NSW Planning Portal
- Complete the online application
- Pay the application fee
Step 4: Council Assessment
- Council reviews the application
- May request additional information (RFI)
- Neighbour notification (14-21 days depending on council)
Step 5: Determination
- Approved with conditions
- Approved as submitted (rare)
- Refused (with reasons)
Step 6: Post-Approval
- Obtain Construction Certificate (CC)
- Appoint Principal Certifier
- Commence work within approval timeframe (usually 5 years)
NSW Planning Portal Guide
The NSW Planning Portal is the central platform for all DA submissions. Here’s how to use it effectively:
- Register: Create a user account
- Find your property: Use the property search tool
- Track your application: Monitor status in real-time
- Respond to RFIs: Upload additional documents quickly
Pro Tip: The Portal now integrates with most council systems, significantly reducing processing times.
Common Reasons for DA Rejection
Based on our analysis of recent determinations:
- Non-compliance with LEP/DCP controls (zoning, height, FSR, setbacks)
- Insufficient documentation (missing SEE, inadequate plans)
- Neighbour objections (privacy, overshadowing, view loss)
- Environmental impacts (bushfire, flooding, heritage)
- Traffic and parking concerns

FAQs
What’s the difference between DA and CDC?
DA is a merit-based assessment by council. CDC is a fast-track approval that must meet pre-set standards. CDC is faster but more restrictive.
Can I withdraw a DA?
Yes, but fees are typically non-refundable after a certain stage.
How long does a DA approval last?
Usually 5 years from the date of determination.
Do I need a BASIX certificate?
Yes, for all residential development in NSW.
What is the role of a Principal Certifier?
The Principal Certifier ensures construction complies with the approved plans and conditions.
