Type an NSW address to see the approval pathway — EXEMPT, CDC or DA — for a granny flat, dual occupancy, extension, pool or new dwelling. Free, computed in code from public planning data.
In most NSW residential zones a secondary dwelling (granny flat) up to 60m² on a lot of at least 450m² with an existing lawful dwelling is complying development (CDC) — about 10 working days under SEPP (Housing) 2021 — and is exempt from s7.11/s7.12 contributions. It drops to a DA if the lot is heritage, flood-affected or below 450m². Check your address above.
CDC is the fast-track pathway when the project meets the SEPP standards and the site has no disqualifying constraint. Heritage, a heritage conservation area, a flood planning area, bushfire Flame Zone/BAL-40 or contamination remove CDC and a DA is required. We compute this in code from the SEPP rules and your zone.
Zone, FSR, height, minimum lot size, cadastre lot size, and heritage/flood/bushfire overlays. Anything that depends on your title — easements, covenants, 88B restrictions or exact dimensions — is shown as "unknown without title documents" and resolved by a paid Investigation.
