Why Council Approval Matters in Landscaping
When planning a landscaping project, many Perth homeowners wonder: “Do you need council approval for landscaping projects in Perth?”
The answer depends on the scope and structural elements involved.
While basic landscaping works like turfing or planting are usually exempt, anything involving walls, construction, or site works may require planning approval or a building permit.
Understanding Council Roles in Landscaping
Each local council in Western Australia enforces planning and building approvals to ensure projects are safe, compliant, and respectful of the surrounding environment.
Their role includes checking that your proposal meets R-Codes, setback rules, and safety requirements.
General Rule: Not All Landscaping Needs Approval
Small, non-structural landscaping — like planting native plants, adding mulch, or installing garden furniture — usually doesn’t require approval.
However, the moment your project involves altering the natural ground level, installing a retaining wall, or modifying boundaries, it enters the approval process.
When Council Approval Is Required
You’ll likely need council approval for your landscaping project if it involves:
- Retaining walls higher than 500mm
- Excavation or fill exceeding 500mm from natural ground level
- Permanent structures such as patios, gazebos, or roof covers
- Driveways that affect street access or street trees
- New swimming pools or water features with electrical or plumbing connections
These changes alter the land, so they trigger planning or building permit requirements.
Retaining Walls and Approvals
A retaining wall is one of the most common structures requiring council approval.
If the retaining wall exceeds 500mm in height, sits on a boundary, or supports another structure, it typically needs both planning approval and building approval.
Ensure your retaining wall complies with structural certification and building codes to avoid future disputes or council dissatisfaction.
Planning Approval vs Building Approval
These two approvals serve different purposes:
- Planning approval ensures your project complies with local planning policies, street setback area rules, and R-Codes.
- Building approval (or building permit) ensures the construction is safe, stable, and meets fire separation requirements and other building codes.
Some projects need both types of approval, depending on scale and location.
The Council Approval Process
The council approval process involves several steps:
- Submitting a development approval or planning application with drawings and details.
- Waiting for assessment under local planning policies.
- Once approved, lodging a building permit application for construction.
The process may take several weeks, depending on complexity and local council workloads.
Development Approval Explained
A development approval (DA) relates to the design and placement of your landscaping project.
You may need a DA if your proposal alters the natural ground level, changes street setback areas, or includes substantial walls or structures.
In Western Australia, DAs fall under the Planning and Development Act 2005 and local town planning schemes.
When Planning Approval Is Needed
You’ll need planning approval if your project affects:
- Boundaries shared with neighbours
- The front setback or street trees
- Natural ground level changes over 500mm
- The visual impact on the surrounding structures
Always consult your local council or a building surveyor before starting — what seems simple may still require approval.
Building Permits and Building Approvals
A building permit or building approval ensures construction is structurally sound and safe.
This includes:
- Retaining walls
- Concrete driveways
- Roof covers or shade structures
- Any building work over a specified height or load
Applications can be lodged through your local council or a private building surveyor for faster processing.
Using a Private Building Surveyor
A private building surveyor can issue certified applications, saving time in the approval process.
They assess whether your building work and landscaping structures meet all building codes and ensure your project is built correctly before issuing approval.
This is particularly useful when timelines are tight or council approval backlogs exist.
What Happens If You Skip Approval
Skipping the council approval process can have serious consequences.
If your landscaping works don’t comply, you could face:
- Council dissatisfaction notices
- Orders to remove or modify non-compliant structures
- Fines or, in extreme cases, forced demolition
Even well-intentioned homeowners are responsible for ensuring their project complies.
Exempt Landscaping Works
Some landscaping tasks are exempt from development approval, such as:
- Basic garden design and planting
- Installing reticulation systems
- Low-level walls or edging under 500mm
- Small water features without plumbing
Always confirm exemption status with your local council, as rules vary by location.
The Importance of Approved Plans
Always work from approved plans.
These show that your project meets local regulations, building codes, and planning policies.
They also protect you if questions arise during construction or sale of your property.
Soil, Site, and Structure Considerations
Before beginning site works, ensure soil removal, fill, or construction doesn’t affect boundaries or drainage.
Perth’s sandy soil can shift easily, so engineers often recommend compacted fill or organic matter mixed with clay for stability.
These measures prevent future walls or structures from failing and keep your project safe.
Consult Experts Early
Your first step should be to consult both your landscape designers and the local council for expert advice.
Professionals familiar with planning approval and building codes can identify potential issues before work begins — saving time and money later.
How to Ensure Your Project Complies
To ensure your landscaping project complies with all development approval and building approval requirements:
- Engage a qualified building surveyor early.
- Confirm council rules before digging or altering land.
- Make sure all structures have proper structural certification.
- Keep all approved documents for reference.
This ensures smooth execution and legal peace of mind.
The Role of Landscape Designers in Compliance
Experienced landscape designers understand local council standards, planning frameworks, and Western Australia’s compliance systems.
They’ll help prepare documentation, drawings, and permit applications — making the approval process simpler and stress-free.
Protecting Your Investment
Following the proper council approval steps protects your property’s value and ensures your landscaping project is both legal and safe.
It also proves your project complies with planning and building approvals, giving future buyers or tenants confidence in its quality.
