The Planning Development and Infrastructure Act 2016 and associated regulations are being progressively phased between 2017 and 2020 to replace the Development Act 1993 and the Development Regulations 2008. The assessment of new development is currently still guided by the Development Act 1993 and Development Regulations 2008 legislation.

The Development Act 1993 establishes Development Plans as the primary legal document to guide new development in South Australia. The Development Plan for each council area contains the zones, maps, and explicit rules that guide and control what can and cannot be done on any piece of land within the area. They are the basis on which applications for new development will be assessed and any appeal decisions are made.

Development Plans outline which land uses are envisaged in a zone and those uses which are not contemplated. Development Plans contain objectives, principles, and policies that will control and affect the design and location of proposed land use activities. The Plans can also spell out the desired character for a given area or zone.

Note that ‘development’ is legally defined in the Development Act 1993 and Development Regulations 2008. Generally, development refers to land use, land division, and physical construction.

In 2020, South Australia introduced a new planning system supported by strengthened regional partnerships, community consultation, and a simplified planning and design rulebook.
