Canning Vale is a large, established family suburb south-east of the Perth CBD. Most of it is relatively flat, so retaining here is less about holding up steep slopes and more about the jobs that come with renovating: pools, patios, raised gardens, granny flats and replacing walls that were put in when homes were first built.

Typical Canning Vale jobs

- Raised garden beds and lawn terraces
- Replacing ageing timber sleeper walls along fences
- Low boundary walls where neighbours have built up their yards
- Walls supporting new patios, outdoor kitchens and granny flats
Flat ground, fences and fill
On flat lots, the most common mistake is building up a yard against a fence that was never meant to retain soil. A dividing fence is not considered suitable for retaining soil (City of South Perth guidance), and the City of Gosnells says a fence should not be used as a retaining wall unless designed to do so. If you’re adding fill near a fence, put a proper retaining wall in first.
Low walls tied to other work
Many Canning Vale walls are under 0.5 m, but the exemption only applies if the wall isn’t associated with other building work. A low wall built as part of a pool or patio project may need to be included in that project’s permit. Ask your pool builder and wall specialist to coordinate.
Which council?
Canning Vale is split between two councils: the City of Canning west of Nicholson Road and the City of Gosnells east of it. Check your rates notice to confirm which one handles your permit.
Permits in Canning Vale: City of Canning
Canning Vale is split between the City of Canning (west of Nicholson Road) and the City of Gosnells (east). The City of Gosnells says any wall retaining more than 0.5 m needs a building permit, and so does a wall of any height that is tied to other building work, encroaches, or affects adjoining land or an existing boundary wall; development approval may be needed for walls over 0.5 m or within 1.5 m of the boundary. The City of Canning publishes a retaining walls information sheet; check with its Building Services. The R-Codes also limit fill within 1 m of a boundary. Full detail in our WA permit guide.
What it might cost
Published Perth guides put typical installed prices as of 2026 at about $260 to $630 per lineal metre for concrete sleeper walls and about $420 to $680 per square metre of face for limestone, before drainage, engineering and permits. These are typical ranges, not quotes; see the Perth cost guide. Your Canning Vale specialist will price your actual site.
Canning Vale retaining wall questions
My neighbour raised their yard and soil is pushing on my fence. Who pays?
Generally whoever changed the level is responsible for retaining it. Talk to your neighbour and get legal advice if needed.
