Building a duplex in New South Wales (NSW) can be a great investment for homeowners and developers, but navigating the approval process can be complex. Thankfully, Complying Development Certificates (CDC) offer a streamlined alternative to traditional Development Applications (DA), allowing for faster approvals under certain conditions.
What is CDC Approval for Duplexes?
CDC approval is a fast-track approval process for residential developments that meet specific criteria set by the NSW government. Unlike a DA, which requires council approval, CDC is assessed by a private certifier and follows State Environmental Planning Policies (SEPPs).
Key Requirements for Duplex CDC Approval
To be eligible for CDC approval, your duplex must comply with:
- Zoning Requirements: Your land must be zoned R2 for dual occupancy under local council planning controls.
- Minimum Lot Size: Most areas require a minimum 400m² lot size with specific frontage requirements of 15m at building line.
- Setbacks & Heights: Must comply 100% with Low-Rise Housing Diversity Code (e.g., front setback of 4.5m+ and max height of 8.5m).
- Private Open Space & Landscaping: Minimum 24m² per dwelling and at least 20% of the lot landscaped.
- Car Parking: At least one parking space per dwelling.
Benefits of CDC Approval for Duplexes
- Faster Approval: Can be approved in as little as 20 days, compared to months for DA approval.
- No Council Involvement: Assessed by a private certifier, reducing bureaucracy.
- Cost-Effective: Avoids additional costs of council submissions and modifications.
Steps to Obtain CDC Approval for a Duplex
- Engage a Building Designer: Ensure your design complies with CDC requirements.
- Preliminary Site Assessment: Check zoning, flood zones, and other constraints.
- Prepare a Compliant Design: Include setbacks, height limits, and open space.
- Lodge Application with a Certifier: Submit architectural drawings, BASIX certificates, and engineering reports.
- Approval & Construction: Once approved, you can start building immediately.
