Before you start transforming your outdoor space, it’s important to know whether your plans require planning (development) approval or a building permit. In Perth and across Western Australia, requirements depend on the scope of work, your site’s zoning, and local council regulations.
Knowing this upfront can save you time, money, and stress down the track. It ensures your project runs smoothly and meets all compliance standards from the very beginning.
What Landscaping Works Might Need Planning or Development Approval?
Whether your landscaping needs council approval depends on the extent of the works and how they interact with your property and neighbours.
Common landscape works that may require planning or development approval in Perth include:
• Retaining walls over 0.5 m high or near property boundaries, especially if they affect neighbouring land or drainage.
• Earthworks (excavation or fill) that alter natural ground levels, water run-off or land stability.
• Tree removal or vegetation clearing, particularly in conservation, heritage or bushfire-prone areas.
• Driveway and paving changes that modify drainage or vehicle access points.
• Swimming pools and spas, which often require both planning and building approvals depending on zoning and setbacks.
• Large water features or ponds that alter water flow or drainage patterns.
• Outdoor structures (pergolas, sheds, garages, play equipment) that exceed height/size limits or are located within setback areas.
• Fencing, especially front boundary or tall boundary fences that may affect sightlines or streetscape.
• Works within heritage or special conservation areas, where additional controls apply to preserve character and local significance.
Every local council has its own requirements, so it’s always worth checking before you start your project.
When Is a Building Permit Required?
A building permit is needed when your landscaping involves structural elements or anything that could pose safety risks. Examples include:
• Retaining walls higher than 0.5 m or supporting other structures or fences.
• Decks, patios or raised platforms elevated 300–500 mm or more above ground level.
• Pergolas, gazebos, shade structures, sheds, or outdoor kitchens involving structural supports, plumbing, or gas fittings.
• Swimming pools and spas, which require structural certification and compliant safety barriers.
• Water features connected to mains or drainage, or with significant excavation or structural components.
A Simple Rule of Thumb
You should review any landscaping work for potential approvals if it:
• Changes ground levels by 500mm or more
• Includes structures over 2.4m high
• Is built within required boundary setbacks
Refer to the Residential Design Codes (R-Codes) and your local planning scheme for guidance.
How Long Do Approvals Take?
• Planning / Development Approval: Typically, 60–90 calendar days, depending on project complexity and whether public advertising or consultation is required.
• Engineering Documentation: Where required, allow 2–4 weeks for preparation and review of structural engineering drawings, subject to consultant availability and timely provision of information.
• Certification: Once engineering documentation is complete, allow 5–10 working days for review and certification by a registered building surveyor.
• Building Permit: Following certification, allow an additional 10–25 working days for building permit approval, depending on the issuing authority and council workload.
When in Doubt, Ask Early
Before starting any work, reach out to your local council’s Duty Planner or Building Approvals team for guidance. Doing work without approval can lead to fines, enforcement notices, or complications when selling your property.
