Development Assessment

State Significant Development (SSD)

Some types of developments are deemed to have State significance due to the size, economic value or potential impacts that a development may have.
Development that is State significant development (SSD) is identified in the State and Regional Development State Environmental Planning Policy.


Types of State Significant Development (SSD)

The Government has identified certain types of development that are SSD, for example:

  • new educational establishments, hospitals and correctional centres,
  • chemical and other manufacturing,
  • mining and extraction operations,
  • tourist and recreation facilities,
  • some port facilities,
  • waste management facilities, and
  • energy generating facilities.

A development proposal for any of the identified development types is SSD if it:

  • is over a certain size,
  • is located in a sensitive environmental area, or
  • will exceed a specific capital investment value.
  • Open configuration options

In addition, some development on identified sites can also be SSD. Identified sites include Sydney Olympic Park, Darling Harbour, the Bays Precinct and Barangaroo.

The full list of SSD development types and identified sites can be viewed in Schedules 1 and 2 of the State and Regional Development State Environmental Planning Policy.

Lodging an application

Once you have determined that your proposal is SSD, you can lodge your application online with the Department.

The Independent Planning Commission (IPC) is the consent authority for SSD applications if the applicant is not a public authority and:

  • the application is not supported by local council,
  • the Department has received 50 or more public objections (petitions and submissions that contain substantially the same text count as one objection), or
  • the applicant has made a reportable political donation.

The Minister is the consent authority for all other SSD applications. In some cases, the Minister may delegate the decision making function to Department staff.

Changes to the SSD application payment process

We’re changing the way we charge applicants fees for assessment. All applicants have to pay a fee to have their application assessed by the department. Our practice to date has been consistent with case law, which allows for application fees to be paid up to the point of determination.  

From 1 July 2021, all SSD applications, including modifications, will require payment before they can be considered lodged. This new way of working provides certainty and consistency to applicants by aligning the timing of payment for development applications.  Fees have increased under the EP&A Regulation 2021 and all invoices issued after 1 April 2022 will reflect the updated fees.

To minimise delays, it is important to make sure information supplied is complete and correct when an application is submitted. This includes, providing a Quantity Surveyor’s Report, where required, to support the Capital Investment Value cited in the application.
