What are the requirements?

Decking may be located up to a side or rear boundary provided it complies with the Residential Design Codes and the City’s Local Law’s relating to Fencing.

Decking over 500mm in height is considered to be the same as a Balcony and as such, requires a setback of 7.5m to side and rear boundaries. Reduced setbacks may be considered via an Application to Commence Development (Development Approval).

Timber decking must be designed and constructed in accordance with AS 1684.2-2010 (Residential Timber-Framed Construction)

Engineer’s details may be required for decking over 500mm in height from Natural Ground Level. Engineer’s details are not generally required for decking less than 500mm in height from Natural Ground Level, however it will be at the discretion of the Building Surveyor assessing the plans as to whether they will be required.
