Towns and suburbs in Mackay include Mackay, Sarina, Walkerston, Marian and Mirani.
Building in Mackay
Mackay lets open carports and shade sails take a lesser road setback where they are open on all sides, front a collector or access street and keep a small gap from the boundary, with post spacing limits. Domestic outbuildings have eave and apex height limits set by the lot, and the house, outbuildings and every other structure together have a site cover cap that also depends on the lot.
One secondary dwelling is allowed per lot, with a floor area cap and a requirement to sit close to the house.
Mackay Regional Council is its own water and sewerage provider and assesses building near its mains itself. It also maps bushfire, flood and landslide, which matters across Mackay, Sarina, Walkerston and Marian. Planning and development applications are listed online.
What we hold for Mackay
For Mackay we hold the council’s own rules for:
- sheds, garden sheds, garages and carports
- patios, pergolas, louvred roofs, decks and shade sails
- pools, fences and retaining walls
- granny flats
- driveways, water tanks and shipping containers
We also hold its current fee schedule.
Build-over of sewer and water assets is decided by the council itself.
At each lot we check the council’s own mapping for flood, bushfire and landslide, 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 Mackay will ask you
Is the carport open, or closed in?
How open the carport is changes whether it needs a fire rated wall near the boundary, and a roller door or a later enclosure reopens the question. A shed never takes the open carport exemption.
How high can a retaining wall and a fence go?
Each takes its own height test, and a retaining wall carrying a fence has its own approval. Both heights go on the sheet for the certifier to read together.
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.
Are there easements, sewer mains or other services?
Work near a sewer or water main goes to the asset owner before the certifier can sign it off, on a timeline of its own. Mapped easements and mains show on the lot as it loads.
The figures for your own lot are read in a minute, from its address.
Every question a certifier asks is on the Queensland page.
