CDC vs DA pathway split
A Complying Development Certificate (CDC) is issued by a private certifier when a property meets all SEPP Housing 2021 standards. A Development Application (DA) goes through council assessment and is required when the property has constraints like heritage listing, flood overlay, or environmental sensitivity.
CDC vs DA pathway split
All CDC records in the NSW Planning Portal have status “Approved” — rejected CDC applications are not published in the open dataset. DA records show status “Determined” for all decided applications — the portal does not distinguish between approved and refused DAs.

| Application count | 0 | 4 |
Cost of development is self-reported by applicants at lodgement and may not reflect actual construction costs. Processing time outliers (>365 days for CDCs, >730 days for DAs) are excluded from median calculations.
