Building work will generally require a development application for Building Approval if you are:
- building a free-standing permanent structure e.g. house or shed
- extending or raising or re-stumping an existing structure
- building a retaining wall over one metre high or a fence over two metres high
- erecting signs, flag pole, mast or tower, aerial or antenna
- swimming pools and swimming pool fencing
- demolishing an existing building or structure (in part or in full)
- altering the structure for a different use (e.g. a shed to house, converting a dwelling to short-term accommodation, an office to a retail shop)
- 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:
- painting or redecorating the interior or exterior of a structure
- remodelling a kitchen or bathroom
If you are intending to undertake building work, you must have a Building Approval. Also, some projects will require you to have a Planning Approval prior to submitting an application for Building Approval.
Development application forms (IDAS forms) are available at the Department of Infrastructure, Local Government and Planning website.
