What we look for in Perth, and why it differs from the suburb next door. in the Perth CBD, 9.0 km from the coast, postcode 6000.
The suburb of Perth covers the central business district and the residential streets running north to Hyde Park. For most buyers, purchasing here means purchasing an apartment, and that changes the inspection completely.
In a strata building the things that matter are mostly things you cannot see from inside the lot. The concrete structure. Waterproofing membranes under bathrooms and balconies, and under any podium or planter sitting above occupied space. The facade and any cladding. Balcony drainage and balustrade fixings. Fire and acoustic separation between dwellings.
None of that is visible from inside a tidy apartment, which is exactly why it gets missed. And in a tall building the cost of putting it right is spread across every owner regardless of where the defect sits.
So read the paperwork. Strata minutes, the maintenance plan, levy history, and any special levy already struck or being discussed will frequently tell you more than an hour walking through the apartment. A defect in common property becomes your cost through levies no matter whose ceiling it is above. The building's finances and its physical condition are really the same question.
Away from the towers the older residential pocket toward Hyde Park is a different proposition. Solid brick, timber floors, and a century of inner city alterations to trace. Those houses are worth buying carefully. They sit on some of the most valuable land in the state and have often been rented for decades.
A concrete apartment on the fifteenth floor has no termite exposure worth speaking of. The risk in this suburb concentrates in two places, and they are worth naming precisely.
Ground floor and podium level lots, where landscaping, planter boxes and courtyard gardens sit against or above structure and keep soil permanently damp. And the older houses toward Hyde Park, which have timber floors on stumps, mature street trees, and the usual century of garden beds banked against original brickwork. Those are ordinary suburban termite conditions in the middle of the city. Where a strata scheme owns the landscaping, responsibility for treatment usually sits with the scheme, so it is worth knowing who acts if something is found.
For a ground floor apartment or a Hyde Park house the combined inspection makes obvious sense, because the planters and gardens a pest inspector examines are the same places where waterproofing and drainage fail. Even higher up, having both done means one attendance and one set of access arrangements through the building manager. Reported under AS 4349.1 and AS 4349.3.
Apartment and strata inspections are the bulk of our work in this postcode, for owner occupiers and investors alike. Practical completion inspections matter on off the plan purchases, where the defect list at handover is always longer than expected and the builder is still liable.
Pre-settlement inspections apply to established apartments, and dilapidation reports to owners near the constant construction in the city. We also do expert witness reports, which in this setting almost always concern water ingress and who has to pay to stop it.
Buying in the Perth suburb almost always means buying an apartment, so the inspection is a strata one and the priorities change completely. What matters is the concrete structure and the waterproofing membranes, especially in bathrooms and on balconies and around podium or planter areas. The facade and any cladding matter too, as do the balcony drainage and balustrade fixings, the fire and acoustic separation between dwellings, plus the condition of common property. On an apartment the building's paperwork often tells you more than the walls: the strata minutes and the maintenance plan, the levy history, and any special levies struck or foreshadowed, because a defect in common property becomes your cost through levies regardless of which lot it sits in. The building's finances and its physical condition are really the same question.
Not all of the suburb is towers. The residential streets toward Hyde Park hold older housing — solid brick, timber floors, and the alteration history of a century of inner-city living — which is a quite different inspection from a tower apartment: it reads rising damp and subfloor condition and the traced alterations instead. The city-centre setting brings traffic and night noise, limited parking, and construction activity on neighbouring sites as ongoing realities. A Perth inspection is usually a strata one, reading the concrete and membranes, the facade and balconies, and the fire and acoustic separation, alongside the building's records and finances, and shifts to a character-home inspection on the older streets toward Hyde Park.
On a Perth apartment the inspection reads the building and its paperwork together. The concrete structure is checked for spalling and movement. The membranes on bathrooms and balconies and any podium or planter areas are read for the water entry that is the commonest strata defect. The facade and cladding are read for condition and compliance, the balcony drainage and balustrade fixings for corrosion and safety, and the fire and acoustic separation between dwellings assessed alongside. The strata minutes, maintenance plan and levy history are read as closely as the walls, since a common-property defect becomes the buyer's cost through levies. On the older streets toward Hyde Park the inspection shifts entirely, reading solid brick and timber floors and subfloor, and a century of alterations, instead.
None of it is guesswork. Reading the stock above into an inspection, these are the checks the Perth pattern pushes to the top of the list:
Perth 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 Perth:
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.
Hyde Park is the fixed point most people in Perth navigate by. Buildings like it are useful to an inspector for a duller reason: they date the area. Whatever era put that up is usually the era that put up the houses around it, and the construction methods of that decade are what we expect to find in the roof.
Highgate, East Perth and Mount Lawley sit on the same ground as Perth, 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.
Northbridge is 1.2 km away but sits on the Spearwood dune system; West Perth is 1.5 km away but sits on the Spearwood dune system; North Perth is 2.9 km away but sits on the Spearwood 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.

9.0 km inland through Perth City, the salt risk in Perth is real but secondary. The same fee weighs an older roof for corrosion alongside the wet areas, the drainage and the movement patterns the Perth City stock tends to show.

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.
Perth is 9.0 km from the coast — outside the highest-exposure band, but close enough that salt-driven delignification is worth checking in an older tiled roof.
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:
