What we look for in Cardup, and why it differs from the suburb next door. 35.7 km from the CBD, 19.6 km from the coast, postcode 6122.
Cardup is rural land sitting between two growth centres, with around eleven hundred people spread across nineteen square kilometres. The surrounding district has been subject to extensive rezoning, and there is community concern about the loss of rural and cultural character. That context is the thing to understand before buying here.
Buying rural land in a district under rezoning pressure means buying into something that may change. Finding out what is proposed for the surrounding parcels is more consequential than anything an inspection of a building will tell you, and the planning information is public.
The properties themselves are sparsely settled rural holdings, so the property is the inspection. Septic or aerobic treatment systems. Bore or tank water. Long private driveways. Sheds, stables and outbuildings that form part of the purchase.
Shire rural land here is used mainly for agriculture and equine activities, so horse properties are common and stables frequently represent real value.
Tributaries of the Wungong and Serpentine catchments cross the district, which means low ground near watercourses with a seasonal water table, and that affects footings and drainage on affected parcels.
State forest and bushland nearby bring genuine bushfire exposure, so BAL requirements matter and a long rural driveway is not always something a fire appliance can use.
Equine and agricultural properties have a particular exposure, and it comes from the infrastructure rather than the house.
Stables, yards and shelters are timber structures sitting on or in the ground, usually built to be functional rather than protected. Fence and yard timbers run for hundreds of metres. Feed sheds and tack rooms sit directly on soil. Bedding and feed attract their own pests and hold moisture.
Paddock irrigation keeps ground damp through summer when surrounding land has dried, and nearby state forest supplies continuous habitat.
On the dwelling, older rural houses on timber floors put the subfloor first. Barriers are generally absent. Settle the scope in writing before anyone attends, because on a holding of this size which structures are included is the commonest source of argument afterwards.
Covering a rural holding properly takes hours once the outbuildings and services are included, and doing it twice makes no sense. Reported under AS 4349.1 and AS 4349.3.
Check the rezoning position for the land around a property. In a district under this much development pressure, what happens on neighbouring parcels will shape both the value and the amenity of what you buy, and it is knowable now rather than after the fact.
Look at low ground in winter. Near a catchment tributary that is the version that matters, and a dry summer inspection will not show it to you.
Buyers want the bore, the treatment system and the outbuildings assessed as specific items. On equine properties the stables warrant a proper look rather than a walk past. They are working structures carrying real value, and they are also the part of the property most likely to have timber in the ground.
Cardup sits on the Bassendean dune system — deep leached grey quartz sand, almost pure, and very free draining. Bassendean sand is about as unreactive as a building site gets, so seasonal footing movement is rarely the story here. The water table is the story. Parts of this system sit over the Gnangara Mound and the standing water level can be within a couple of metres of the surface.
What that means in practice, on a house in Cardup:
Landform is assigned from the suburb's position on the Swan Coastal Plain rather than from a site soil test. It tells you what to expect, not what you have. A site classification to AS 2870 is a different exercise and a different report.
Darling Downs, Oldbury and Oakford sit on the same ground as Cardup, so the footing behaviour and the drainage problems tend to repeat across all of them. If you are comparing houses across those suburbs, you are largely comparing the same site conditions.
Whitby is 3.2 km away but sits on the Guildford Formation; Byford is 4.7 km away but sits on the Guildford Formation; Mundijong is 4.8 km away but sits on the Guildford Formation. That is the useful thing about this part of Perth: the ground can change inside a few kilometres, and with it what an inspection is looking for.
On site classification: any soil zone quoted for a suburb is indicative, inferred from geography rather than surveyed. A real AS 2870 classification comes from geotechnical work on your actual block and can differ from the one next door. We report what we observe; we do not read your soil class off a map.
The inspection is visual and non-invasive, over the readily accessible areas, reported to AS 4349.1. Our inspectors physically enter the roof space, as long as there is sufficient access. Report within 24 hours of the inspection.

Flat fee, the same in Cardup as anywhere: $440 inc. GST for a pre-purchase building inspection, or $616 inc. GST with the timber pest scope added in the same visit. Full price list →
Well inland at 19.6 km from the coast, out in Serpentine - Jarrahdale, coastal salt is not the first thing an inspection in Cardup chases. The fee buys closer work on footing movement, site drainage and the reactive-ground behaviour of the South East suburbs, with delignification checked only where a tiled roof meets a busy corridor.

Yes. Our inspectors physically enter and inspect the roof space, as long as there is sufficient access to do so safely. Where access is restricted, the report says so plainly rather than implying we saw more than we did.
At 19.6 km inland, Cardup carries lower coastal-salt exposure, so delignification is not the first thing we would expect. It remains possible near heavy arterial corridors or industrial emissions.
Within 24 hours of the inspection itself, not 24 hours from booking. On a pre-purchase or pre-settlement job that timing is the whole point, because your leverage disappears once you are committed.
We would rather you checked than took our word for it. These are the bodies that actually hold the records and set the rules:
