Site plans for Busselton, Western Australia: drawn in minutes
Need a site plan for a shed, patio, carport, deck, pool or granny flat in Busselton? Site plans and assessments in minutes, drawn over the real lot.
Building in Busselton
Busselton sorts outbuildings by zone. In the Residential and Centre zones a shed within the state's housing codes needs no approval, and a bigger or taller one can still gain approval within the City's limits, which step up from small or dense lots to larger blocks; where the density coding and the lot size point different ways, the lower limits apply. On a vacant residential lot a single shed may be supported only once the house foundations are finished, with no bathroom or toilet and no one living in it.
Rural residential lots get a larger allowance shared by sheds, carports, patios and shade structures, inside any building envelope, and the conservation and bushland zones take the larger figure too. In the Rural and Viticulture and Tourism zones the policy sets no area cap. The City of Busselton runs an online application search.
What we hold for Busselton
For Busselton 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
At each lot we check 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 Western Australia
In Western Australia the local government is the permit authority and issues the building permit, and an application can arrive with the design already checked by a private registered building surveyor, who issues a certificate of design compliance. Some small structures need no building permit, but every structure still has to meet the planning side: on a house lot, the Residential Design Codes and the local planning policies. Work that meets their deemed-to-comply standards, on a place that is not heritage protected, needs no planning approval; work that does not goes to the local government as a development application, judged against the design principles. The site plan shows the structure's distance to each boundary, its wall height and the open space left on the lot. The lot's density coding decides how close a structure can go, as per the Residential Design Codes (R-Codes) and the Building Act 2011.
Drawing the plan
Type the property address, the lot’s real boundaries load from official land records in Western Australia, 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 permit or a development application.
What a certifier in Busselton will ask you
How big can a granny flat be, and how far from the house?
The council caps a granny flat’s floor area, and some councils also limit how far from the house it may stand. The sheet prints the floor area and dimensions the distance to the house.
How deep is the pool?
The depth decides whether the water needs a barrier, and the barrier has to be in place before the pool is filled. The barrier is what gets inspected, so the sheet shows where it runs and every gate with its swing.
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.
Is the patio a pergola, a louvred roof or a solid roof?
An open pergola and a roofed patio are treated differently near the boundary, and louvres that shut to shed water count as a roof. Roofed, it also adds to the site cover total on the sheet.
The figures for your own lot are read in a minute, from its address.
Every question a certifier asks is on the Western Australia page.
