Basic Requirements for Development Applications

(Carport, verandah, garage, swimming pool and other minor building works)

In order for your application for building approval to be assessed as quickly as possible, the following information should be provided with your application:

Completed Forms

Development Application Form

Electricity Declaration Form

Indemnity Insurance (required for all domestic building work valued $12,000 and over)

CITB Levy (required for all work over $40,000)

Plans required

Site Plans (example below)

Site plans should be at a scale of 1:200 (1 cm = 2m) showing the whole of your block and show the location of all the current buildings on the block (eg. sheds, houses, swimming pools, regulated / significant trees). Site plans should also indicate where the new building work is going to be located and method of stormwater disposal.

Plan view (example below)

The plan view of the structure should be at a scale of 1:100 (1 cm = 1m) and show what you are proposing to build from looking above. This view is also used to show the location of beams, posts, direction of sheeting and spacings of all members and an overall size

Elevations (example below)

Elevations are views of the completed structure from each side – i.e.. from the front and the side.  On the elevations, the overall height of the structure is shown, materials and how the structure is to be attached to any existing buildings

Sectional Drawings (example below)

A sectional drawing of the structure is a view of the structure 'cut away'. Sectional drawings show in detail of how the structure is fixed to the foundation (soil) and also how it is to be attached to other buildings in more detail

Other Details

Swimming Pools

Applications for swimming pools need to show:

  • All the pool fencing as well as the gate access to the pool. It is important to show the height and type of existing fencing (if you are using it as part of the pool fence) and also the type of fencing that complies with AS1926.1.
  • Location of the pool pump in reference to the site boundaries and details of whether it is to be housed within a structure designed to mitigate noise
  • Structural engineering certification.
  • Location of the CPR chart.

Pitched Roof Pergolas

Applications for pitch timber pergolas can be dealt with using the Timber Framing Code. Steel framing pitched roof pergolas need to have an engineer's calculations to test the steel member sizes and to also specify the connection details. Those plans which are received with no calculations will not be approved until calculations have been provided.


If you are constructing a building using standard building specifications, a copy of the specification related to the job should be attached to the applications.

These 'standard' designs use specific connection and footing details which need to be adhered to during constriction. For 'non-standard' designs (ie. using your own design), a Certificate of Structural Adequacy from a structural engineer will need to be provided with your application.

Cutting or Filling Land

If the existing ground surface is to be modified by cutting or filling, details of the final level to be created, relative to the existing site levels.  Any retaining walls should also be identified.
