Do I need council approval to build a granny flat in NSW?

Not always. Most granny flats qualify under a Complying Development Certificate (CDC) instead of a full Development Application (DA). CDC approvals are: • faster • simpler • usually approved within weeks • handled by a private certifier. We manage the entire approval process on your behalf.

What is a CDC granny flat?

A CDC granny flat is a secondary dwelling that meets NSW planning rules and can be approved without going through council. It allows: • quicker approvals • lower costs • fewer delays • streamlined paperwork. This is the most common approval pathway for backyard homes in NSW.

When is a full DA required instead of CDC?

A Development Application may be required if: • your block doesn’t meet CDC rules • your site has planning restrictions • heritage overlays apply • bushfire or flood zoning requires extra assessment. If CDC isn’t possible, we guide you through the DA process.

How long does granny flat approval take?

Typical timeframes: • CDC → 2–6 weeks • DA → 6–12+ weeks. CDC is significantly faster, which is why we assess eligibility first.

What size granny flat can I build?

Is my block suitable for a granny flat?

Suitability depends on: • land size • slope • access width • sewer & services • planning controls. We offer a feasibility check to assess your site and confirm what’s possible.

Do I need separate services for the granny flat?
