How to Stay Compliant with Landscaping and Retaining Wall Rules on the Sunshine Coast
If you’re planning a new retaining wall, deck, or landscaping project on the Sunshine Coast, it’s not just about good design — it’s about compliance.
Council rules can feel complicated, but understanding them early helps you avoid fines, rebuilds, and project delays.
Here’s what you need to know before you start building.
Why Landscaping Regulations Matter
They Protect You — and Your Neighbours
Council requirements for landscaping, retaining walls, and drainage aren’t there to slow you down — they’re there to keep your property (and your neighbours’) safe.
They ensure your structures are engineered properly, water flows where it should, and no one ends up with damage after heavy rain.
They Add Long-Term Value
A compliant outdoor structure adds value and confidence to your property. When it comes time to sell, buyers and inspectors will appreciate the paperwork and approvals being in order.
When You Need Council Approval
Not every project requires approval, but many do — especially if it changes ground levels, supports soil, or affects drainage.
Retaining Walls
You’ll need council approval if your wall:
- Is higher than 1 metre, or
- Is within 1.5 metres of a boundary, or
- Supports a structure, driveway, or other load.
In most cases, you’ll also need engineering certification for any wall above 1 metre to ensure structural stability.
Decks, Pergolas, and Outdoor Structures
Similar height and boundary rules apply to decks and pergolas. If your structure exceeds a certain height or is attached to the dwelling, council approval is often required.
Drainage and Stormwater
Any landscaping that redirects water, alters surface levels, or affects drainage paths may require approval or inspection.
Stormwater must always flow to an approved discharge point — never onto neighbouring properties.
Understanding Setback and Boundary Rules
Typical Setback Distances
Most retaining walls or landscaping features must sit at least 1.5 metres from the boundary unless approved otherwise.
These rules help prevent disputes and allow safe access for maintenance or repairs.
Working Near Fences or Shared Boundaries
If your wall or fence sits on or near a boundary line, you may need written agreement from your neighbour. The Dividing Fences Act 1991 (QLD) outlines each party’s responsibilities and cost-sharing arrangements.
Engineering and Certification
Why It Matters
Engineering certification confirms that your retaining wall or structural landscaping element meets Australian Standards. Without it, your builder or landscaper may not be covered by insurance — and neither will you.
What’s Required
- Structural drawings from a registered engineer
- Soil and site assessment
- Proof of compliance for footing depth, materials, and drainage
- Certification lodged with council where required
Professional landscapers like Greener Landscaping handle this process from start to finish — ensuring your paperwork and construction meet every requirement.
Common Compliance Mistakes to Avoid
Building Without Checking Site Levels
Sloping sites require careful planning. Even a small change in height can trigger the need for council approval or engineering.
Ignoring Drainage
Redirected stormwater can cause erosion, flooding, or even damage neighbouring properties — one of the fastest ways to attract complaints.
Assuming “She’ll Be Right”
The most common issue we see? Homeowners trusting unlicensed contractors who “don’t worry about approvals.” It might save time upfront, but it always costs more later.

How to Get Approvals Sorted Early
Step 1 — Plan Your Project Properly
Start with a concept plan showing boundaries, heights, and materials. If your site has a slope, include contour lines or levels.
Step 2 — Check Council Requirements
Visit the Sunshine Coast Council website or talk to a local certifier. Their planning team can confirm whether your project is exempt or requires approval.
Step 3 — Work with Licensed Professionals
Choose a landscaper who knows local rules and works with qualified engineers. This ensures everything is compliant from the ground up.
FAQs
Do I always need council approval for a retaining wall?
No — walls under 1 metre high that don’t support extra load and are more than 1.5 metres from a boundary usually don’t need approval. Always confirm for your specific site.
Can I build right up to my boundary?
Not usually. Most retaining walls and landscaping structures must be set back from the boundary unless approved with engineering documentation.
Who is responsible for retaining walls between neighbours?
Responsibility depends on location and purpose. If the wall benefits one property (for example, creating a flat area), that owner typically pays for it. Shared walls require written agreement.
Can Greener Landscaping help with approvals?
Absolutely. We can organise engineering, certification, and council paperwork so you can enjoy a smooth, fully compliant build from start to finish.
