Planning and Development

This section deals with land-use planning and the assessment of development proposals. Most of the law in this area is contained in the Planning, Development and Infrastructure Act 2016 (SA) and all references are to this Act unless otherwise stated.

A new planning system

The Planning, Development and Infrastructure Act 2016 (SA) was assented to on 21 April 2016, and was gradually implemented across 5 years. The new planning system fully commenced on 19 March 2021 and completely replaced the previous planning system under the repealed Development Act 1993 (SA). The Planning, Development and Infrastructure Act 2016 (SA) was implemented in 3 phases across all council regions in South Australia.

The three phase implementation of the new Planning, Development and Infrastructure Act 2016 (SA) was implemented as follows:

  • Phase 1: Implemented in outback areas of South Australia from 1 July 2019
  • Phase 2: Implemented in rural council areas with small towns and settlements from 31 July 2020
  • Phase 3: Implemented in urban councils and councils with regional towns and cities from 19 March 2021.

The key feature to the new planning system is the replacement of the previous Development Plan process with the new Planning and Design Code. Under the new system, development applications are submitted and tracked through an online ‘ePlanning’ portal.

The Planning and Design Code is the single source of planning policy in South Australia. The planning policies are applied on a property basis. To find out the planning policies which apply to your property, use the search function available on the PlanSA website.
