Granny Flat Council Approval (DA) — When and How

When CDC is not available, a DA through your local council is required. Buildana (Lic. 487805C) manages DA applications across all Western Sydney councils.

Processing Times by Council

Fairfield: 40–60 days | Liverpool: 50–80 days | Canterbury-Bankstown: 50–80 days | Cumberland: 40–60 days | Blacktown: 40–70 days

These start from lodgement of a complete application. Incomplete applications receive RFIs that add 4–8 weeks.

Maximising Approval Success

1. Pre-lodgement meeting ($300–$500) to identify issues early 2. Exceed minimum standards — more landscaping, better setbacks 3. Complete documentation — avoid RFIs 4. Neighbour engagement — reduce objection risk 5. Comply with DCP intent, not just minimum numbers
