What we look for in Kenwick, and why it differs from the suburb next door. 14.5 km from the CBD, 20.7 km from the coast, postcode 6107.
Kenwick holds three different kinds of land in the one suburb. Residential, light industrial, and semi rural smallholdings of several acres. It also contains the Brixton Street Wetlands, relatively pristine native wetlands of significant conservation value.
What a property actually is varies enormously here, so the first job is working out which Kenwick you are buying into. A house on a suburban block, a smallholding of several acres, and a dwelling beside light industrial land are three different inspections with almost nothing in common.
On the acreage the property is the inspection rather than the house. Septic and leach systems. Bore and tank water. Outbuildings and sheds that need assessing in their own right or explicitly excluding. Long private driveways. On those blocks the sheds are often worth more to the owner than the dwelling.
Land adjoining the Brixton Street Wetlands carries constraints on clearing, drainage and development, and those constraints are real. Check them before making plans that depend on altering the land.
The Canning River bounds the suburb to the south west, so river flats there are low with alluvial soils and flood context. Roe and Albany Highways form other edges, and blocks near either take traffic and heavy vehicle noise. Kenwick is also one of the early farming communities of the colony, with a pioneer cemetery among its historic sites.
Conservation wetlands beside remnant farmland is a demanding combination. The wetlands are protected, which means the vegetation stays, and vegetation of that quality holds well established colonies permanently.
On smallholdings the exposure spreads across the whole site. Old sheds sitting directly on soil. Fence lines with posts set into damp ground running for hundreds of metres. Stacked timber and disused equipment that has not moved in years. Remnant orchard and market garden infrastructure. Agree in writing which structures are included before anyone attends, because scope is the commonest disagreement on an acreage job.
On the suburban blocks it is more familiar. Slab edge and perimeter, with barriers on older stock long finished.
On a several acre holding the combined inspection is the only practical arrangement, because covering the dwelling, the outbuildings and the services takes hours before travel is counted. It also puts one person across how the wetland edge affects the particular property. Reported under AS 4349.1 and AS 4349.3.
Because the suburb mixes zoning so thoroughly, we do commercial and industrial inspections here alongside residential and rural work. Those are separate disciplines with separate priorities.
Buyers of smallholdings often want the effluent system and water supply assessed specifically. That is sensible. Neither is covered by assumption, and both are expensive to put right.
Where wetland constraints affect what may be done with a parcel, we have prepared reports for owners in dispute about it. Those disputes are usually about drainage, and they are far easier to argue with a dated record than without one.
If you are looking at acreage here, walk the boundaries before you make an offer. What is stored along a back fence tells you more about the property than the house does.
Kenwick sits on the Guildford Formation — alluvial clay and sandy clay laid down by the Swan and Canning systems. This is the reactive ground. Clay here shrinks and swells with moisture, which is what puts stepped cracking through brickwork and takes doors out of square between seasons. Articulation joints matter on these sites, and a great many older houses do not have them where a current standard would want them.
What that means in practice, on a house in Kenwick:
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.
Wattle Grove and Orange Grove sit on the same ground as Kenwick, 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.
Maddington is 1.9 km away but sits on the Bassendean dune system; Beckenham is 3.2 km away but sits on the Bassendean dune system; Langford is 3.3 km away but sits on the Bassendean dune system; East Cannington is 3.5 km away but sits on the Bassendean dune system. 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.

Well inland at 20.7 km from the coast, out in Kalamunda, coastal salt is not the first thing an inspection in Kenwick 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 20.7 km inland, Kenwick 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:
