Thinking about building a retaining wall on the Gold Coast? Before you start digging, it pays to understand the council rules that apply. Knowing when and how to get approval can save you time, money, and a lot of stress later on.
The Gold Coast City Council (GCCC) enforces strict guidelines to protect property owners and the local environment, and that goes especially for flood-prone or canal-front areas.
When Approval Is Required
In most cases, you’ll need building approval if your retaining wall:
- Is 1 metre or higher
- Supports extra loads, such as a driveway, fence, or building
- Alters natural water flow or redirects drainage
- Sits close to a boundary or easement
Smaller decorative walls under one metre often don’t require formal approval. However, they still need to be structurally sound and built in line with Queensland Building Regulation 2021 and relevant Australian Standards.
Even “small” jobs can create big headaches if they’re not properly designed.
Council vs Private Certification
Council Application
If you apply directly through the council, you’ll need to supply:
- Engineering drawings
- Soil test data
- Drainage and footing plans
Approval times vary depending on complexity, but most applications take around 2–3 weeks to process.
Private Certification
Many homeowners prefer to use a private certifier for faster turnaround. Private certifiers check your engineering documents, ensure your wall meets AS 4678 – Earth Retaining Structures, and confirm compliance with GCCC setback rules before issuing your permit.
The key advantage? Less red tape and more flexibility with scheduling your build.
Key Considerations for Coastal Blocks
Building near the coastline comes with its own challenges:
- Drainage: Direct runoff away from neighbouring properties and structures.
- Salt Air: Use corrosion-resistant steel posts and quality coatings to extend your wall’s life.
- Setbacks: Maintain proper distances from boundaries, easements, and fences.
Don’t ignore these things. Otherwise you could find yourself being served with rectification orders, facing insurance issues, or even being forced to rebuild later.
FAQs: Gold Coast Retaining Wall Regulations
Can I build a retaining wall myself?
You can for small, non-structural garden walls. Anything structural or load-bearing must be built or certified by a licensed builder or engineer.
What happens if I skip approval?
You risk fines, stop-work orders, and being required to remove or rebuild the wall at your own expense.
How do I know if my wall is compliant?
Ask your builder for their engineering certification and approval documents before construction begins.
Do retaining wall approvals expire?
Yes. Approvals generally remain valid for 12 months from the date they’re issued.
