Decks

Multiple dwellings, commercial developments or caravan parks

All decks associated with multiple dwellings, commercial developments or caravan parks will require Development (Planning) Approval. Proceed to Step 2.

Residential single house or grouped dwelling

Development (Planning) Approval is not required for decking 500mm or less in height from the natural ground level.

Decking 500mm or greater from natural ground level does not require a Development (Planning) Approval if it complies with the following:

• Setback requirements: The setback requirements depend on your property's R-Code density. 
• Please note: For dual-density code not developed to the higher density, adhere to the R20 setback requirements.

• Privacy screens: If your deck is within 7.5 metres of the side or back boundary, you must install a privacy screen at least 1.6 metres high from the deck surface, made from durable materials.
• Additional requirements: If your property is located within a structure plan area, additional requirements may apply.

Not sure of your R-Code or if your property is in a structure plan area? Insert your address into our online mapping system to view the R-Code and structure plan details. Contact the City of you need assistance.

If you do not require Development (Planning) Approval, proceed to Step 3.

If your project does not comply with the requirements set out in Step 1 above, you will need to apply for Development (Planning) Approval. This requires submitting an application form, along with building plans and a cover letter. Application fees will apply.

For detailed information, refer to the Requirements for planning applications page.
