Part 5 identifies the category of development and category of assessment (i.e. if, and what type of a development application is required) and the assessment benchmarks for assessable development and requirements for accepted development (e.g. applicable codes) for development (e.g. land uses, subdivision, operational work and building work) within the planning scheme. Part 5 also outlines when a local plan changes the category of development or category of assessment from that of a zone and where an overlay changes the category of development or category of assessment from that of a zone or local plan.
