Each planning scheme sets out whether development is impact assessable, code assessable, development requiring compliance assessment, self-assessable or exempt. These are typically referred to as ‘levels of assessment’ or ‘assessment categories’ and represents the range of assessment categories set out in the Sustainable Planning Act 2009. Planning schemes identify whether applications such as 'making a material change of use' or 'reconfiguring a lot' are either impact assessable or code assessable. Stated simply, impact assessment applications need to be publicly notified and receive a broader assessment by the Council and any State referral agencies. With a higher level of scrutiny, impact assessable applications require extra care and attention. Code assessable applications do not require public notification but can still be complex and require a detailed assessment. On the other hand, some code assessable applications can be relatively simple and straightforward.
