Building a granny flat in Perth has never been more popular, but navigating the regulatory landscape can be daunting. With recent updates to the R-Codes, homeowners have more freedom than ever—if they know how to work within the system.
Understanding the New R-Code Flexibility
The Western Australian government has recently simplified the process for secondary dwellings. The key change? In many residential zones, you no longer require full planning approval for a compliant granny flat under 70m², provided it meets the setback and open space requirements of your specific lot.
This “deemed-to-comply” status significantly reduces build timelines, moving projects from the drafting table to the construction site in weeks rather than months. However, specific requirements around parking, landscaping, and privacy screening remain strictly enforced.
“The goal of these changes is to encourage multi-generational living and urban infill without compromising the character of Perth’s established suburbs.”
Key Site Requirements for Your Project
re you visit a display centre, it’s worth checking these three critical factors on your property:
- Setback Requirements: Ensuring the structure is far enough from boundaries.
- Open Space Ratios: Maintaining enough backyard for drainage and lifestyle.
- Services Access: Identifying where plumbing and electrical connections will tie in.
The Importance of Turnkey Delivery
While the R-Codes have become more flexible, the technical requirements for a building permit remain rigorous. This is where a turnkey builder like Classic Patios adds the most value. We manage the structural engineering, council liaison, and compliance certifications as part of one fixed price.
When you visit our Joondalup or Canning Vale display villages, our consultants can run a preliminary check on your suburb’s specific requirements while you walk through the physical models.
