Cost breakdown & calculator ↗Granny flat approval in NSW, the fast way.
Most granny flats skip council entirely via Complying Development. Here's what your block needs — and read the full guides in our journal.
450 m² & 12 m wide
The block must be a residential zone, at least 450 m² with 12 m of width at the building line.
Up to 60 m²
A secondary dwelling capped at 60 m² keeps the fast CDC pathway open — no full council DA.
CDC in ~10 days
A private certifier assesses against a fixed checklist — approval in as little as 10 business days.
We lodge it
We prepare plans, check setbacks and easements, and lodge the CDC for you.
