Building a new home or development in Perth is an exciting venture—but it’s not without its complexities. From local council rules to statewide legislation, there are a number of critical regulations you must follow before laying the first brick. Failing to comply can lead to costly delays, redesigns, or even legal issues.

At SMG Construction, we understand the importance of building right the first time. That’s why we’ve created this guide to help you navigate the key building regulations in Perth, Western Australia. Whether you’re planning a custom home, investment property, or subdivision, here’s what you need to know.

1. Local Council Approval

Before any construction begins, you must receive planning and building approvals from your local council. Each local government in Perth (e.g., City of Stirling, City of Joondalup, City of Wanneroo) has its own zoning rules, land use policies, and development guidelines.

Key Considerations:

  • Zoning: Your land must be zoned for residential or mixed-use development and must align with your local zoning code.
  • R-Codes: The Residential Design Codes of Western Australia (R-Codes) determine how many dwellings you can build and what the minimum lot size is.
  • Development Application (DA): Required if your proposed build doesn’t comply with all R-Code standards.

Pro Tip: Engage a builder like SMG Construction early in the process—we liaise with councils and handle documentation to streamline your approval process.

2. Building Permits

Once planning is approved, you’ll need a Building Permit from your local council or a registered building surveyor. This ensures your plans meet the Building Code of Australia (BCA), which forms part of the National Construction Code (NCC), and comply with Australian building standards.

Common Requirements:

  • Certified building plans
  • Structural engineer sign-off
  • Energy efficiency reports
  • Termite treatment details
  • Bushfire Attack Level (BAL) assessment (if applicable)

Delays in this stage can hold up your construction timeline significantly. Working with a professional builder who submits complete and compliant documentation is crucial.

3. Environmental and Energy Compliance

Sustainability is a growing focus in Western Australia. Homes built in Perth must now meet minimum energy efficiency standards.

Things to Check:

  • 6-Star Energy Rating: All new homes must achieve at least a 6-star rating under the Nationwide House Energy Rating Scheme (NatHERS).
  • Water Management: Perth’s dry climate means water-sensitive urban design (WSUD) is often required. Think rainwater tanks, greywater systems, and efficient plumbing.
  • Tree Preservation: Some suburbs have tree protection policies. You may need special permission to remove mature trees from your lot.

4. Bushfire and Flood Zone Compliance

With changing climate conditions, more areas in and around Perth are now designated as bushfire-prone or flood-risk zones. This has major implications for your build.

Bushfire Zone? You May Need:

  • A BAL (Bushfire Attack Level) assessment
  • Fire-resistant construction materials
  • Ember-proof vents and flyscreens

In a Flood Zone?

  • You may need elevated construction
  • Additional drainage systems
  • Council reports and hydrological studies

Ignoring these regulations can result in unsafe homes and denied occupancy certificates. At SMG Construction, we assess these risks early to ensure full compliance.

5. Subdivision and Strata Regulations

If you’re planning to subdivide or build multi-dwelling units, there are additional rules to follow.

Key Requirements:

  • Minimum lot sizes (according to R-Codes)
  • Common property access
  • Strata title approvals
  • Infrastructure upgrades (e.g., sewerage, roads)

Land development in Perth requires collaboration with surveyors, town planners, and utility providers. At SMG Construction, we provide end-to-end solutions, so you don’t have to juggle all these parties yourself.

6. Heritage and Character Area Guidelines

Some suburbs in Perth—especially older inner-city areas like Fremantle, Subiaco, and Mount Lawley—have heritage overlays or character codes.

This Could Mean:

  • Preserving original facades or materials
  • Designing new builds to match surrounding streetscapes
  • Additional planning approvals or heritage assessments

Failing to meet these rules could lead to redesigns or rejected permits. Our team at SMG Construction ensures your new home blends style with compliance.

7. Construction Site Regulations

Even during the build, regulations apply. Site management, safety, and waste disposal are all closely monitored by councils and WorkSafe WA.

Key Rules:

  • Permitted work hours (typically 7am–7pm weekdays)
  • Temporary fencing and signage
  • Sediment control and stormwater management
  • Asbestos removal procedures (for demolitions)

We pride ourselves on running clean, compliant, and professionally managed building sites—protecting your project, your neighbours, and the environment. We also conduct site assessments to ensure all requirements are met prior to construction.

8. Licensing and Insurance

You can’t just hire anyone to build a home in Perth. Only registered builders with the Building Commission of WA are legally allowed to construct or manage residential projects over $20,000.

Builder Requirements:

  • WA builder’s license
  • Home Indemnity Insurance (mandatory for residential work over $20,000)
  • Adherence to building warranties and defect liability periods

SMG Construction is fully licensed and insured, giving you peace of mind that your investment is protected.

9. Occupational Health and Safety (OHS) Compliance

Construction must meet strict OHS standards, which include:

  • Site safety management plans
  • Training for all workers and contractors
  • Risk assessments
  • Regular inspections

Any incident on-site can delay your build, increase costs, and cause legal problems. We invest in comprehensive safety systems and training to prevent issues before they arise.

10. Final Inspections and Occupancy Permits

Before you move in or lease out your new property, you’ll need:

  • A final inspection by a building surveyor
  • An Occupancy Permit (if required for Class 2–9 buildings)
  • Compliance certificates for plumbing, electrical, and energy systems

Our team handles all the final touches—so you can move into a fully approved, compliant home without stress.
