Building a custom home in Perth requires navigating various permits and approvals. This comprehensive guide breaks down the essential building permits needed for your custom home project in Western Australia, helping you understand the process from start to finish.
Understanding Building Permits in Perth
Building permits (also called building approvals) are legal documents that confirm your proposed construction complies with the Building Code of Australia (BCA), relevant Australian Standards, and local planning requirements. In Perth, these permits are typically issued by your local council or a private building surveyor.
A building permit ensures your custom home will be structurally sound, safe, and meet minimum standards for health, amenity, and energy efficiency. Without proper permits, you risk costly fines, demolition orders, and difficulties when selling your property.
Types of Permits Required for Custom Homes
1. Planning Approval
Before applying for a building permit, you may need planning approval from your local council. This confirms your proposed home complies with:
- Zoning requirements
- Residential design codes (R-Codes)
- Local planning schemes
- Heritage considerations (if applicable)
Planning approval focuses on how your home will impact the surrounding area, including setbacks, building height, site coverage, and overall design.
2. Building Permit
The main permit required is the building permit itself, which comes in two forms:
Certified Building Permit (BA1): Requires a private building surveyor to certify your plans before submission. Processing time is typically 10 business days.
Uncertified Building Permit (BA2): The local government assesses and certifies your application. Processing time is usually 25 business days.
For custom homes, a certified permit (BA1) is often preferred as it’s generally faster and allows you to choose your building surveyor.
3. Demolition Permit
If your custom home project involves demolishing an existing structure, you’ll need a demolition permit (BA6) before any demolition work can begin.

Start by engaging:

Step 3: Submit Your Application

Special Considerations for Perth Custom Homes
Bushfire-Prone Areas
Many Perth suburbs are designated as bushfire-prone. If your property falls within these areas, you’ll need:
- A Bushfire Attack Level (BAL) assessment
- Compliance with AS3959 construction standards
- Additional fire safety measures incorporated into your design
Coastal Areas
For properties near the coast:
- Corrosion protection requirements apply
- Wind loading considerations are stricter
- Special foundations may be needed for sandy soils
Heritage Considerations
If your property has heritage significance or is in a heritage area:
- Additional planning approvals are required
- Stricter design guidelines apply
- Conservation requirements may limit changes
Common Permit Issues and Solutions
Setback Variations
If your design doesn’t meet standard setback requirements:
- Apply for a variation through your planning application
- Provide justification for the variation
- Consider redesigning if the variation is unlikely to be approved
Overlooking and Privacy
To address privacy concerns:
- Ensure compliance with visual privacy requirements in the R-Codes
- Consider screening or window placement
- Adjust floor levels if necessary
Site Works and Retaining
For sloping sites requiring significant earthworks:
- Include detailed site works plans with your application
- Obtain engineering certification for retaining walls
- Consider drainage implications
Local Council Specific Requirements
Different Perth councils may have specific requirements:
City of Perth: Focus on design excellence and sustainability
City of Stirling: Strict adherence to local planning policies
City of Joondalup: Detailed requirements for coastal developments
City of Fremantle: Strong heritage considerations
Always check with your specific local council for their unique requirements.
Timeframes and Planning
Allow adequate time for the permit process:
- Planning approval: 60-90 days (if required)
- Certified building permit: 10-15 business days
- Uncertified building permit: 25-30 business days
Factor these timeframes into your project schedule to avoid delays.
