In Victoria, storage sheds do not require a permit or approval if they meet the following guidelines.
• Have a floor area of no greater than 10m²
• 3m or less in height, or, if situated within 1m of a boundary, is no more than 2.4m in height located no further forward than the front wall of the single dwelling

A 10ft shipping container thereby does not require a permit. For other sizes, we suggest you contact your local Council and check their individual requirements as each one is different.
