Do You Need Council Approval for a Kitchen Renovation in WA?

When a Kitchen Renovation Requires a Building Permit in WA

Most kitchen renovations in Western Australia do not require council approval or a building permit—but some do, and getting it wrong can result in fines, orders to undo completed work, or complications when you sell your property. Understanding the rules before you start saves significant headaches down the track.

Under the Building Act 2011 and the Building Regulations 2012, building permits are administered by your local council (the “permit authority”) and are required for any building work that is classified as construction, demolition, or alteration of a building’s structure. The key question for kitchen renovations is whether your project crosses the line from cosmetic work into structural alteration.

If you are planning a complete kitchen remodelling project, distinguishing between simple maintenance and structural work is the first step in your planning process.

Permit Requirements by Renovation Type

The Difference Between Building Permits and Planning Approval

These are two separate processes that Perth homeowners often confuse:

• Building permit: Ensures the work complies with the National Construction Code (NCC/BCA) and Australian Standards for structural integrity, fire safety, and accessibility. Administered under the Building Act 2011. The permit fee varies by council but is typically $200–$800 for residential work.
• Planning approval (development approval): Ensures the work complies with your local council’s planning scheme and the Residential Design Codes (R-Codes). Only required if you are changing the external appearance of the building, extending the footprint, or changing the use of a space.

For a standard kitchen renovation that stays within the existing walls of your home, you typically need neither. The moment you remove a structural wall or extend the kitchen into a new area, you likely need both.

Structural Changes: What You Need to Know

Removing a wall to open up the kitchen to a living or dining area is one of the most popular renovation requests in Perth, particularly in older homes across Morley, Balcatta, and Scarborough where small, enclosed kitchens were the standard design in the 1960s through 1980s. If the wall is load-bearing, you will need:

• A structural engineer’s design and certification for the replacement beam (typically a steel or laminated timber beam sized to carry the load). Engineering fees range from $500–$1,500.
• A building permit from your local council, which requires submission of the engineering drawings and typically takes 10–20 business days to process.
• A registered builder to carry out the work. Owner-builder permits are available but have their own requirements under the Building Services (Registration) Act 2011, including a mandatory owner-builder course for projects valued over $20,000.

Determining whether a wall is load-bearing requires professional assessment. If you are unsure about the structural integrity of your home during a kitchen renovation, consulting with experts early is vital.

As a general guide, walls that run perpendicular to the roof rafters or trusses are more likely to be structural, but the only way to be certain is to have a builder or engineer inspect the framing.

Compliance Certificates for Trade Work

Even when a building permit is not required, certain trade work must be completed by licensed professionals who issue compliance certificates:

• Electrical: All electrical work requires a licensed electrician who lodges a Notice of Completion with EnergySafety WA. This covers new circuits, additional power points, rangehood wiring, and under-cabinet lighting installation.
• Plumbing: Licensed plumber required for all water supply and drainage connections. Compliance documentation provided on completion. This applies to sink replacement, dishwasher connections, and any hot or cold water supply modifications.
• Gas: Licensed gas fitter required for gas cooktop and oven connections. A gas compliance certificate is issued and lodged with EnergySafety WA. Gas work must be inspected before the appliance is used.

Keep all compliance certificates in a safe place. They are critical documentation when selling your home, as buyers’ conveyancers and building inspectors routinely request them. Missing certificates can delay settlement or give buyers leverage to negotiate a lower price.

What Happens If You Renovate Without Required Approvals?

If you carry out building work that required a permit without obtaining one, your local council can issue a building order requiring you to either obtain retrospective approval (which is more expensive and not always granted) or demolish the non-compliant work and restore the original structure. This also creates problems at sale, as unapproved structural work must be disclosed and can reduce your property’s value or deter buyers entirely.

When in doubt, contact your local council’s building department before starting work. Councils across Perth metro—from the City of Joondalup to the City of Rockingham—have building teams who can advise whether your specific renovation requires a permit. It is a free enquiry that could save you thousands.

For cosmetic kitchen upgrades like cabinet resurfacing, benchtop replacement, or splashback installation, you can proceed without permits as long as you use licensed tradespeople for any plumbing, electrical, or gas work involved.
