Complying Development Certificates - FAQs
A CDC is a fast-track approval that combines planning and construction approval for eligible development.
A CDC is assessed against fixed complying development standards. A DA is assessed by council under the standard planning pathway.
No. Only projects that meet the applicable complying development standards can use CDC. Other projects usually need a DA.
A CDC has a statutory lapsing period. We confirm the relevant commencement and expiry requirements when your certificate is issued.
