See whether Complying Development or a full DA is more likely in your state. Not a substitute for certifier advice.
FAQs
Approval wizard questions
What is the difference between CDC and DA for a granny flat?
Complying Development (CDC) is a faster certifier-led pathway when your proposal meets fixed standards in the Housing SEPP or equivalent state code. A Development Application (DA) goes through council assessment when you cannot meet those standards or your lot has overlays.
Can I use this wizard instead of a certifier?
No. This wizard only flags which pathway is more likely based on your inputs. A private certifier or council still makes the final call after surveying setbacks, BASIX, flood overlays and other site-specific rules.
