What approvals do I need? - Decking

Description Decking can be described as a flat surface or platform capable of supporting weight, similar to a floor, but typically constructed outdoors. Decking is often elevated from the ground and usually connected to a building.
Do I need approval?

Planning Approval (also referred to as Development Approval) may be required for decking over 500mm in height from natural ground level. Should it be required, planning approval must be obtained prior to a building permit being issued.

All decking requires a Building Permit, regardless of the height or floor area.

What do I need to submit?


Please refer to the City's DA Checklist - Residential Additions for a complete list of the information required to apply for planning approval.


Please refer to the City's Decking Information Sheet for a complete list of the information required to apply for a building permit.

If your structure has already been constructed without prior approvals and/or permits, please refer to our Unauthorised Works page which includes a separate application checklist.
