What we look for in North Perth, and why it differs from the suburb next door. 2.8 km from the CBD, 8.3 km from the coast, postcode 6006.
North Perth is old, established and built mainly of solid brick from the early 1900s. Not double brick with a cavity. Solid brick, laid before damp proof courses were standard, which means these walls behave nothing like a house from the 1990s and should not be judged as though they do.
Rising damp is normal in a wall like this. Salt frets the brick at the base over decades. Neither is a reason to run, and an inspector who writes them up as catastrophic is not helping you buy a house in this suburb. What matters is the degree, whether anything is making it worse, and what it has done to the timber nearby.
The floors are suspended timber on stumps, so the subfloor gets inspected. Ventilation, moisture, stump condition, joists, borer. Very often the subfloor has been compromised by a later addition built straight over the original vents, which is a finding in itself.
Which brings us to the real issue in North Perth. The suburb is deep into a renovation wave as buyers move back toward the city, and recent renovation makes a house look sound without making it sound. We find load bearing walls removed or altered. Rear additions of wildly varying quality. Roof spaces opened up. Services rewired and replumbed to an unknown standard. Some approved, some not. A beautifully presented cottage can hide structural changes nobody documented, so tracing what was done and under what approval matters here more than almost anywhere.
Timber floors on stumps, mature gardens and a century of additions. Termites like all three.
The subfloor is the priority because that is where colonies establish and where the damage runs unseen. Old stumps, buried timber, disused form-work and garden beds banked against the original brick all help them along. Any chemical barrier installed before the mid 1990s is finished, whatever the paperwork says, and a lot of North Perth houses have never had one since. Where an addition has been built over the old subfloor we lose sight of the very area that needs watching, and the report will say where our access stopped.
These two jobs overlap almost completely in a suburb of timber floored, heavily renovated houses. The damp that rots a bearer is the damp that feeds a colony. The subfloor is the same subfloor. The addition that blocked the vents caused both problems at once. Booking the building and timber pest inspections together gets you one attendance and one account of the house, reported to AS 4349.1 and AS 4349.3 respectively.
Renovation drives most of our other work here. Building stage inspections while a rear addition goes up catch problems while the builder is still on site and still liable. Practical completion inspections do the same at handover. If you are extending and your neighbour is close, which in these streets they usually are, a dilapidation report protects both of you.
We also see subdivided lots and new units built behind original cottages, and those bring party walls, shared drainage and strata arrangements into the picture. Pre-settlement inspections apply to all of it.
The defining stock in North Perth is solid brick from the early 1900s, laid without a cavity and generally without a damp-proof course, which means rising damp is a normal condition rather than a defect in itself, salt attack frets the brickwork at the base of walls, and the walls behave quite differently from the double-brick cavity construction that came later. These houses are judged by the standards of their own construction. But the single biggest inspection issue here is renovation: North Perth is undergoing extensive renovation as buyers move back toward the city, so expect removed or altered load-bearing walls, rear additions of varying quality, roof spaces opened up, re-plumbed and rewired services of unknown vintage, and work that may or may not have been approved. Recent renovation makes a house look sound; it does not make it sound, and that distinction is the heart of the job here.
Homes of this era sit on suspended timber floors over stumps, so subfloor inspection — ventilation, moisture, stump and joist condition, and borer — is essential, and it is frequently compromised by later additions built over the vents, which is itself a finding. Mid-century additions to early-1900s homes commonly used asbestos sheeting, so that is assessed before any renovation or demolition. A North Perth inspection reads the solid early-1900s brick by the standards of its own construction, scrutinises the extensive and variably-approved renovation work behind the fresh presentation, and gets into the subfloor wherever the additions have not closed it off.
The renovation is where a North Perth inspection concentrates. Any wall that may once have been load-bearing is read for how its removal was handled, the rear additions are assessed for quality and for whether they were approved, and the re-plumbed and rewired services are traced for age and standard, since fresh finishes routinely conceal work of unknown vintage. The solid early-1900s brick is read for rising damp at the base of the walls and salt fretting, and the subfloor is entered wherever later additions have not built over the vents, so the stumps, joists, ventilation, moisture and any borer can be assessed. Mid-century asbestos sheeting in additions is noted for assessment before any further work.
None of it is guesswork. Reading the stock above into an inspection, these are the checks the North Perth pattern pushes to the top of the list:
North Perth sits on the Spearwood dune system — residual yellow and grey sand over a Tamala Limestone core, with the rock often close to the surface. Limestone near the surface makes for stable footings and expensive excavation. Where the rock is shallow, older houses often sit directly on limestone footings, and those are the ones to look at for rising damp and salt damp at the base of the wall.
What that means in practice, on a house in North 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.
Rosemount Hotel is the fixed point most people in North 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.
Menora, Leederville, Coolbinia and Northbridge sit on the same ground as North 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.
Mount Lawley is 1.9 km away but sits on the Bassendean dune system; Highgate is 1.9 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.

8.3 km inland through Perth City, North Perth is off the worst of the coastal strip, so the fee spreads wider: an older tiled roof still gets checked for salt corrosion, but drainage, the wet areas and the way the Perth City ground moves take up more of the visit.

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.
North Perth is 8.3 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:
