Building in Western Downs
In Western Downs, flood is the overlay to check first. The planning scheme regulates building work only through its airport environs, heritage, flood hazard and stormwater overlays, so sheds, carports, pools, fences and retaining walls otherwise take their setbacks and site cover from the state rules. Minor operational work is accepted subject to the operational work code.
A secondary dwelling needs a minimum lot size and must be attached to the house or sit close to it, with more distance allowed on rural residential and rural land. It is capped at the lesser of a fixed floor area or half the house, and adds a car space. Where a house on a small lot is assessed, the accommodation code limits site cover and height.
Western Downs Regional Council maps flood itself and lists applications for Dalby, Chinchilla, Miles and Tara on Development.i.
What we hold for Western Downs
For Western Downs we hold the council’s current fee schedule.
At each lot we check the council’s own mapping for flood, and the state’s mapping for flood, bushfire, landslide, heritage and native vegetation. We also read the council’s application register for past applications on the lot.

How approval works in Queensland
In Queensland a building certifier, usually a private one, gives the building approval for work on a house lot, and the council comes in for the parts it controls. The smallest structures are accepted development and need no building approval when they meet the state's standards. Anything larger needs building approval, and a structure that sits closer to a boundary or the street than the siting rules allow also needs the council's agreement to a siting variation; an overlay or the zone in the council's planning scheme can add a planning approval on top. The certifier and the council read the site plan for where the structure sits against each boundary, the house and any easement. Its size, its height and its distance to each boundary decide which way it goes, as per the Queensland Housing Code and the Building Regulation 2021.
Drawing the plan
Type the property address, the lot’s real boundaries load from official land records in Queensland, and you place the structure over the aerial view. The plan prints to scale with boundary lengths, setback distances, a north arrow, a legend, a site coverage table and a title block, as the site plan for a building approval or a DA.
What a certifier in Western Downs will ask you
Is the lot in an overlay, and what is the zoning?
A flood, bushfire, heritage or character overlay can bring a planning approval on top of the building approval, and the zone decides which of the council’s rules apply. The mapped overlays are read at the lot as the structure goes on the plan.
Who gives the approval, and who draws the plan?
The certifier or the council gives the approval, and the site plan can come from the builder, the supplier, a drafter or the owner, as long as it is clear and to scale. A surveyor comes in where the position of a boundary on the ground has to be fixed.
How big is it, and how big is the lot?
The size and the height decide whether the structure needs building approval at all, and the council can add limits that step with the lot’s size. The sheet prints the lot’s area and the running total of site cover.
Is the patio, shed or carport attached to the house?
Whether it fixes to the house changes how it is classified, and so what the certifier checks near the boundary. The sheet says which it is.
The figures for your own lot are read in a minute, from its address.
Every question a certifier asks is on the Queensland page.
