When it comes to constructing an attached garage to Secondary Dwelling (commonly known as Granny Flat ) under a Complying Development Certificate (CDC), the answer is a resounding YES. However, navigating the nuances of associated structures and compliance is crucial. Let's break down the key considerations.
Understanding Ancillary Structures
Garages fall under the category of 'Ancillary Structures,' as defined in Clause (1)(g) of Schedule 1 in the State Environmental Planning Policy (Housing) 2021. This classification is further detailed in Clause 4, where 'Attached Ancillary Structure' explicitly includes a garage attached to a secondary dwelling.

1 年Recently achieved this for a client as a CDC. However the difference was that the existing principal dwelling house on the lot had no garage so it was a combined CDC under Housing SEPP & Codes SEPP. One of the ways around it. Complex to say the least in terms of the conflicting controls and how they interact/contradict but achievable.
Development Assessment Planner
1 年Last time when I was assessing DA for a secondary dwelling with attached garage, I was unable to approve under DA as the main dwelling had no garage and it was looking garage was for secondary dwelling. However, we can approve attached garage with secondary dwelling under CDC and lots of owner is going for CDC now. I believe it’s very informative for the certifiers.
