Building Regulations in Perth: What Property Owners Need to Know

Navigating the world of building regulations in Perth can feel overwhelming for property owners planning to build, renovate, or extend their home or commercial property. Whether you're a first-time homeowner, a developer, or a business owner, understanding your legal obligations and council requirements is essential to ensure your project runs smoothly—and remains compliant.

At Boda Building Group, we’ve helped hundreds of Perth clients bring their visions to life while strictly following the region’s building codes and planning regulations. In this guide, we break down the key things you need to know before starting your next construction project in Perth.

1. Understanding Local Building Codes in Perth

In Perth and throughout Western Australia, building regulations are governed by the Building Act 2011 and enforced through the National Construction Code (NCC). These frameworks are designed to ensure all buildings meet standards of health, safety, sustainability, and structural integrity.

The City of Perth and other local councils across WA also implement additional planning policies and zoning codes that must be met. Whether it’s a new home, renovation, or commercial fit-out, all building work must align with these national and local rules.

2. Do You Need Building Approval or Planning Approval?

There are two primary types of approvals required in Perth:

• Planning Approval (Development Approval): Focuses on land use, design aesthetics, and how the building fits into the community. Required for major works like new dwellings, extensions, or multi-dwelling units.

• Building Approval (Building Permit): Ensures the physical construction meets safety and code compliance. Required for most structural work, including sheds, pools, garages, or interior alterations.

Boda Building Group helps clients identify the correct type of approval needed and submits plans for council approval efficiently.

3. Projects That Require Building Permits in Perth

In Perth, the following works typically require a building permit:

• New home constructions

• Home extensions or additions

• Structural renovations

• Carports, garages, and patios

• Swimming pools and pool fencing

• Retaining walls above 500mm

• Commercial fit-outs

Even seemingly minor work like removing a load-bearing wall or installing a new window may need a certified permit. When in doubt, it’s always best to check with your local council or consult a professional builder in Perth.

4. Role of a Registered Builder

A registered builder, like those at Boda Building Group, plays a crucial role in ensuring your building project complies with Perth’s construction regulations. We take responsibility for:

• Submitting necessary documents and plans

• Coordinating with engineers and certifiers

• Liaising with council and other authorities

• Ensuring works meet Australian standards

In most cases, projects over a certain value (typically over $20,000) must be carried out by a Registered Builder in WA. This provides assurance to the council—and to you—that your project is in capable hands.

5. Key Documents Required for Building Applications

To get a building permit in Perth, you typically need:

• Architectural drawings and site plans

• Structural engineer certifications

• Energy efficiency report

• Home indemnity insurance (if over $20,000)

• Certificate of Design Compliance (CDC)

A qualified builder can prepare and gather all necessary documentation to streamline the application and avoid delays.

6. Timeframes and Fees

The timeline for obtaining building approval in Perth varies based on project complexity, but on average:

• Residential applications: 10 business days

• Commercial applications: 15–25 business days

Fees also vary depending on project value and location. Local councils may also charge development fees, infrastructure levies, and inspection fees. Boda Building Group always provides clients with transparent timelines and fee expectations.

7. Heritage and Zoning Considerations

Perth has numerous heritage-listed properties and specific zoning laws that impact what can and cannot be built. If your property falls within a heritage precinct or special control area, you may need extra approvals and design concessions.

Zoning codes influence:

• Plot ratio and site coverage

• Building height and setbacks

• Use of land (residential, commercial, mixed-use)

We work closely with Perth councils to interpret these codes and obtain the necessary permissions before breaking ground.

8. Sustainability and Energy Efficiency Compliance

All new buildings in Perth must comply with energy efficiency requirements under the National Construction Code (NCC). These include minimum insulation levels, glazing performance, and ventilation design.

Builders must submit a NatHERS (Nationwide House Energy Rating Scheme) report or Deemed-to-Satisfy assessment as part of their building application. At Boda Building Group, we ensure your design meets these requirements without compromising style or comfort.

9. Common Mistakes That Delay Projects

Many property owners in Perth unknowingly delay their projects due to:

• Incomplete or inaccurate documentation

• Starting construction without a permit

• Failing to meet planning setbacks or height restrictions

• Not using a registered builder for major work

Avoiding these pitfalls saves time and money. Working with an experienced Perth builder ensures every box is ticked before construction begins.
