What we look for in Joondanna, and why it differs from the suburb next door. 4.8 km from the CBD, 7.1 km from the coast, postcode 6060.
Joondanna Heights was the first declared township in what is now the City of Stirling, gazetted in November 1939. The name was later shortened. That makes it one of the oldest declared areas in the district. The original housing reflects it.
The original stock is 1940s and 50s timber framed workers' cottages. Not brick. Timber framed, not double brick, which changes the inspection entirely.
On a timber framed house the subfloor carries the structure, so stumps, bearers, joists, ventilation and moisture all get assessed directly rather than inferred from what is visible upstairs. Asbestos era materials are likely on anything unrenovated, and cladding of that period frequently contains it.
Many of those cottages have been removed for unit development, and that is the second thing to establish. Joondanna now holds old timber cottages standing beside brand new unit blocks, sometimes on adjoining lots. Those are two entirely different inspections with almost nothing shared between them.
Single detached housing still dominates, but the teardown and rebuild pressure is real given the suburb sits about six kilometres from the city.
Inner but inland, so salt and delignification are a low priority here, and the roof inspection concentrates on fixings, roof plumbing and workmanship instead.
A timber framed cottage from the 1940s is the higher risk building type in Perth, and this suburb has a lot of them. The structure itself is food, the subfloor gives access and cover, and eighty years is a long time for anything to go unnoticed.
So the subfloor is where inspection concentrates. Mud leads on stumps and piers. Damage in bearers and joists, particularly under wet areas where old plumbing has been patched rather than replaced. Ventilation blocked by paving, raised beds or a later addition built across the vents.
Eighty year old gardens hold buried timber and old stumps. Any barrier is absent or long expired.
In the new unit stock the picture reverses. Concrete and modern construction, with exposure limited to ground floor landscaping and courtyard planters where responsibility usually sits with the scheme.
On a timber framed cottage everything that matters sits under the floor, and both reports are read off the same bearers by the same torch. Opening the hatch once is the obvious arrangement. Reported under AS 4349.1 and AS 4349.3.
Active teardown means condition records matter for an old cottage next to a demolition or excavation. Unreinforced or timber framed buildings on old footings do not tolerate vibration well, and a dated record beforehand is worth far more than an argument afterwards.
We do handover inspections on the new unit stock, and staged inspections where an old cottage is being restumped or reclad. That work is far easier to assess while open than after it is closed in and lined.
If you are buying an original cottage here with a view to renovating, get the subfloor assessed before you set a budget. On a timber framed house of this age it is where the money is.
Joondanna is one of Stirling's oldest declared areas, from 1939, and its original stock is 1940s-50s timber-framed workers' cottages. The ones still standing need the full timber-frame read: stumps, borer, framing, subfloor, with asbestos-era materials likely on the originals. This is genuinely old inner stock, and where a cottage survives un-modernised its structure and services are well past their intended life, so the inspection weights toward the timber structure and the aged fabric.
The other half of the Joondanna story is teardown. There is active replacement of the old cottages with unit blocks, so you routinely find an old timber cottage standing beside a brand-new unit development, which is two very different inspections, and the new development brings fresh strata stock into the suburb. Where a home borders active construction next door, a dilapidation record before the work starts is worth having. Inland, salt and delignification are low priority. The Joondanna picture is old timber-frame cottages alongside new strata, with the age of the original stock and the construction next door being what an inspection reads.
On a surviving Joondanna timber cottage the inspection is a structural read of old timber: the stumps for settlement and rot, the framing where visible, and the subfloor entered where access allows, with borer and decay the recurring findings. The 1940s-50s fabric means asbestos-era materials are genuinely likely, so eaves, linings and fencing are noted for licensed assessment rather than sampled. Where a cottage has been extended, the additions are traced for approval and workmanship. And where the old stock has already given way to units next door or on the block, the inspection shifts to the strata picture, reading common property, shared drainage and the concrete and membrane detailing that new unit blocks bring.
None of it is guesswork. Reading the stock above into an inspection, these are the checks the Joondanna pattern pushes to the top of the list:
Joondanna 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 Joondanna:
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.
Coolbinia, Yokine, Mount Hawthorn, Tuart Hill, Menora and North Perth sit on the same ground as Joondanna, 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.

7.1 km inland through Stirling, Joondanna 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 Stirling 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.
Joondanna is 7.1 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:
