The Queensland Development Code (QDC) sets out specific design, setback and siting requirements for detached dwelling houses (i.e. Class 1a), except where the Southern Downs Planning Scheme identifies an alternative requirements.
The Southern Downs Planning Scheme identifies alternative setback provisions for dwelling houses in the Rural zone, and on lots more than 1.0 hectares in the Rural residential zone, as follows:
Rural residential zone – on a lot more than 1 ha, 10 m from boundaries of the lot
Rural zone - 60 m from the side and rear boundaries, and any boundary with a gravel road
Planning approval is required from Council to build a dwelling within these required setbacks.
The setbacks for dwelling on other allotments are stipulated as Acceptable Solutions in the following parts of the Queensland Development Code (QDC), which can be accessed on the website of the Department of Housing and Public Works:
For example, the standard setbacks required for a single storey dwelling on an allotment of at least 450m2 and a road frontage of more than 15 metres are:
- 6 metres from the front road boundary; and
- 1.5 metres from the side and rear boundaries.
Different requirements apply for dwellings over 4.5 metres in height, or located on a corner allotment or narrow lot. You will need to check the QDC to determine what setbacks apply to your land.
If you propose to construct a dwelling within the setbacks required by the QDC you will need to refer your building application to Council, and demonstrate how you can comply with the relevant Performance Criteria of the QDC.
