What we look for in Karawara, and why it differs from the suburb next door. 6.6 km from the CBD, 11.3 km from the coast, postcode 6152.
Karawara was developed through the 1950s and 60s by the State Housing Commission and under War Service Homes, alongside Manning, Salter Point and their neighbours. It then acquired something those suburbs did not. Curtin University's Bentley campus sits immediately beside it.
That proximity reshaped the suburb. Completely. A substantial student and investor rental market grew up here, and it drove unit and townhouse development alongside the original government housing. Two markets, one postcode.
So establish house versus strata first, because the two are entirely different purchases. In a unit complex the common property, the shared drainage and the levy position matter as much as anything inside the lot, and a scheme's spending decisions reach every owner regardless of which dwelling a defect sits in.
On the original 1950s and 60s stock, expect the fabric of that period. Asbestos era materials wherever renovation has not reached. Services either original or through one ageing replacement. Wet areas well past a second cycle.
Student tenancy leaves its own marks. They are worth looking for. Houses converted to multiple tenancies, sometimes with rooms added or subdivided. Heavy wear through wet areas and floors. Maintenance deferred by owners who have never lived in the building.
Where a conversion has happened, ask whether it was approved, because an unapproved one is usually a fire separation and plumbing problem as much as a compliance one.
The Canning River system lies nearby, so low blocks carry a higher water table and damp.
Density is the local factor. Shared walls, shared structure, shared problems. Where unit and townhouse development has gone in among the houses, shared walls let a colony travel between dwellings through structure that no single owner can inspect, and treating one side alone rarely works.
Access to a shared subfloor or roof space may need a neighbour's cooperation, and in a strata arrangement responsibility usually sits with the scheme rather than an individual owner. Establish who acts before something is found rather than after.
On the detached government stock the barrier is long finished. Rarely replaced, too. Seventy years of garden has buried the slab edge or the subfloor vents in most cases.
River proximity supplies moisture on the low blocks, and rental tenure means small leaks run longer than they would in an owner occupied house.
On a tenanted or strata property, arranging access is the awkward part of any inspection, and doing it once for both assessments saves genuine time. Reported under AS 4349.1 and AS 4349.3.
Ask for the approval history on any house that has been carved into rooms. Floor plans get redrawn after the fact, and a diagram is not evidence that anyone signed anything off.
Investor purchases make the final inspection before settlement worth booking, since an occupied house and an empty one present differently. Strata work is a large share of what we do here, where the scheme's records decide whether a unit is a sound buy.
Karawara 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 Karawara:
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.
Waterford, Manning, Bentley, Como, Salter Point and Shelley sit on the same ground as Karawara, 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.
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.

11.3 km inland through South Perth, Karawara is far enough from the water that salt takes a back seat. The same fee goes into footings, drainage and the ground movement typical inland, and the tiled roof is checked for delignification only near heavy traffic.

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 11.3 km inland, Karawara 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:
