Development Assessment Panels

Under the Planning and Development (Development Assessment Panels) Regulations 2011, DAPs must be administered by an officer(s) of the Department of Planning, Lands and Heritage, and the CEO of the Department must establish a DAP website.

Development Assessment Panels report directly to the Minister for Planning, and do not form part of the Department of Planning, Lands and Heritage or the Western Australian Planning Commission. 

DAP application types and values

Development Assessment Panels (DAPs) will meet and determine development applications within certain class and value thresholds set in the DAP regulations. There are three types of DAP applications:

  • Mandatory DAP applications
  • Optional "Opt-in" DAP applications
  • Local government delegated applications.

All applications are first lodged with the local government as per standard practice.

Mandatory DAP applications

These are development applications which must be determined by a Development Assessment Panel (DAP) and cannot be determined by a local government or the Western Australian Planning Commission (WAPC). Mandatory applications must meet the following value thresholds:

DAP Mandatory value threshold
City of Perth $20 million or more
Rest of the State $10 million or more

Optional "Opt-in" DAP applications

These are development applications where the applicant may choose to have the application determined by a Development Assessment Panel (DAP), or by the local government or Western Australian Planning Commission (WAPC) under the normal process. In order to be considered an "opt-in" application, the application must fit within the following value thresholds:

DAP "Opt-in" value threshold
City of Perth Between $2 million - $20 million
Rest of the State Between $2 million - $10 million

Local government delegated applications

The WAPC and local governments may choose to delegate their decision-making authority for applications which fit the optional ‘opt in’ criteria for Development Assessment Panel (DAP) applications to a DAP. Therefore a DAP will also determine applications of a type upon which either of these bodies have chosen to delegate their authority.

Either of these bodies may take advantage of this option by following the process of formally delegating their authority to a DAP.

To achieve this, a written instrument outlining the terms and the extent to which that body's authority is transferred to the DAP, must be prepared to the CEO of the Department. Also, in the case of a local government, an absolute majority of the local government's council must support the decision to delegate that body's authority, before such delegation can occur.

 The local government will be required to pay the associated DAP Application fee in accordance with Development Assessment Panel (DAP) regulations, Schedule 1 – Fees for applications

A DAP which is authorised by either the local government or the WAPC to decide delegated applications cannot then hand over that authority to another organisation.

The DAP will be responsible for deciding such applications and must treat them in the same way as any other DAP application.

Excluded applications

Under Development Assessment Panel (DAP) regulations, development applications relating to the following classes of development are "excluded development applications".  These applications will not be able to be determined by a DAP:

  • construction of a single house
  • construction of less than 10 grouped dwellings or multiple dwellings
  • construction of carports, shade sails, outbuildings or sheds
  • development in an improvement scheme area
  • development by a local government or the WAPC.

All Development Assessment Panel applications will still be lodged with the local government and assessed by the local government and/or the WAPC. Following assessment, a report from the responsible authority will be forwarded to DAP members, via the DAP secretariat, with recommendations for consideration when determining the application at a DAP meeting.

View DAP applications in PlanWA

PlanWA is a public mapping tool that provides ready access to planning data across Western Australia, including information on DAP applications.

The interactive PlanWA viewer enables users to:

  1. Utilise an address search tool
  2. Discover DAP region boundaries
  3. Obtain application details – including address, development description, status, decision, cost and history information
  4. Link to DAP agenda and minutes.

Currently, DAP applications from 2014 onwards are available, with progress underway to include archived applications.

The PlanWA page contains further information and a detailed instructional video on how to use it.
