Understanding Building Approvals: DA vs. CC Explained
When planning a new building project in NSW—whether residential, commercial, or remedial—understanding the approval process is essential. Two terms you’ll often hear are DA (Development Application) and CC (Construction Certificate). While they are closely related, they serve very different purposes in the journey from design to construction. Here’s what you need to know:
What is a Development Application (DA)?
A Development Application (DA) is the formal request submitted to your local council seeking permission to carry out a development. It’s essentially asking, “Can I build this?”
The DA focuses on the concept and impact of your proposed development. It addresses factors such as:
- Building design and aesthetics
Appearance, massing and how the development fits with the local area.
- Land use and zoning compliance
Whether the proposed use is permitted and complies with council planning controls.
- Environmental impact and sustainability
Assessment of ecological, water and energy impacts, where applicable.
- Heritage considerations
Assessment of any heritage values and required conservation measures.
- Neighbourhood and community impact
Consideration of privacy, overshadowing, traffic and amenity effects.
Council reviews the DA to ensure the proposal aligns with planning controls, community standards, and state regulations. Once approved, you’ll receive Development Consent, which allows you to progress to the technical documentation and construction approval stages.
What is a Construction Certificate (CC)?
A Construction Certificate (CC) is the next step after DA approval. While the DA answers “Can I build this?”, the CC answers “How will it be built safely and correctly?”
The CC focuses on technical details and compliance with the Building Code of Australia (BCA). It requires detailed structural and engineering documentation, such as:
- Structural design and documentation
Engineered drawings and calculations that demonstrate safety and performance.
- Civil and stormwater drainage design
Detailed drainage, site works and external works documentation required for construction.
- Fire safety compliance
Specifications and documentation to meet fire safety and egress requirements.
- Building materials and specifications
Information on materials, fixings and workmanship standards.
- Construction methods
How the design will be implemented on-site safely and effectively.
A CC can be issued by either the local council or an accredited private certifier. Construction cannot legally commence without a valid Construction Certificate.
Key differences between DA and CC
| Aspect | Development Application (DA) | Construction Certificate (CC) |
|---|---|---|
| Purpose | Seeks approval for the concept and design of the development | Ensures the technical construction details meet standards |
| Authority | Local Council | Local Council or Private Certifier |
| Focus | Planning, zoning and community impact | Building Code compliance and technical design |
| Stage | Submitted at the start of the project | Required before construction begins |
Why both are important
Skipping or misunderstanding these approvals can result in costly delays, compliance issues, or even legal consequences. Together, the DA and CC ensure that your project is:
- Appropriate for its location
- Safe for construction and use
- Compliant with council and state regulations
