Development applications are required if a development is considered an assessable development under the Sustainable Planning Act 2009 ( 2.6 MB).
To determine if your proposed development is an assessable development, you will need to look at the following planning instruments:
- the Sustainable Planning Regulation 2009, schedule 3
- your local government's planning scheme.
The types of developments which are assessable development and therefore require a permit vary for each local government area. As a general rule, a development application must be lodged if you are:
- building any free-standing permanent structure
- extending or raising an existing structure
- building a retaining wall over one metre high or a fence over two metres high
- erecting signs.
You may also be required to lodge a development application if you are:
- clearing native vegetation
- demolishing an existing building or structure (in part or in full)
- changing the use of the land (e.g. a house to a block of units; an office to a retail shop; a wheat farm to a piggery)
- altering the exterior of a heritage place
- carrying out significant structural changes to an existing building.
Unless the property is heritage listed, you do not need a development application if you are, for example:
- painting or redecorating the interior or exterior of a structure
- remodelling a kitchen or bathroom
- performing minor internal structural changes to an existing structure.
