Retaining wall approval requirements differ by state and council. Here's what's generally required — we confirm the exact pathway for your specific site.
Most Australian councils require certified structural engineering for retaining walls above a certain height (commonly around 1 metre, though this varies), or for any wall that supports a structure, driveway, pool or significant surcharge load — regardless of height. Below that threshold, engineering is still strongly recommended for safety even where formal approval isn't required.
Requirements vary by state and even by individual council, and can change over time. Rather than guess at your specific pathway, we confirm exactly what's required for your address and wall as part of your quote — so you get the right documentation the first time.
Whatever your state's process, the core documentation is similar — we prepare all of it as part of your design engagement.
The engineering basis for your design, ready for certifier review.
Detailed, buildable drawings for lodgement and construction.
Your engineer's certificate confirming the design meets AS 4678 and relevant codes.
Where required, sign-off confirming the wall was built to the certified design.
