Retaining Walls Joondalup

Joondalup and its neighbouring suburbs are built over rolling coastal dune country, with limestone ridges and noticeable slopes in many streets. Lots of established homes here already have limestone walls from when the suburbs were developed, and many are now due for repair, extension or replacement.

Limestone country

One Perth landscaper lists Joondalup among the coastal Spearwood-dune suburbs: yellow-brown sand, often with limestone bedrock close to the surface. That helps explain why limestone walls are so common here, and why excavation can hit rock. If your specialist needs to cut into the slope or drill post holes, rock can affect time and cost.

The City’s step-by-step process

The City of Joondalup sets out a clear sequence: work out whether development (planning) approval is needed (it isn’t if the works meet the R-Codes and the City’s residential policies), apply if it is, then work out whether a building permit is needed, and apply either certified (BA1 with a BA3 certificate from a registered building surveyor) or uncertified (BA2 with the City’s retaining wall checklist). Some areas are also covered by the City’s Housing Opportunity Areas policy, which can change the rules.

Material choice

Limestone keeps the look of most Joondalup streetscapes; concrete sleepers are a slim option on side boundaries; engineered block suits tall walls under pools or driveways.

Permits in Joondalup: City of Joondalup

The City of Joondalup says no building permit is needed only where a wall is 0.5 m or less, is not part of (and doesn’t require) building work to protect adjoining land, and doesn’t adversely affect neighbours. Planning approval is needed unless the works comply with the R-Codes and City policies. The R-Codes also limit fill within 1 m of a boundary to 0.5 m above natural ground unless a local development plan says otherwise, so check any estate LDP. 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 Joondalup specialist will price your actual site.

Joondalup retaining wall questions

Do I need approval for a 400 mm garden wall?

Usually not a building permit, provided it isn’t tied to other building work or affecting the neighbour, but it still has to meet the R-Codes, particularly in the front setback.
