Retrospective Building Approvals in Perth WA

Have you recently purchased a property or are you preparing to sell, only to discover that certain structures were built without local council permission?

Whether it is an oversight from a previous owner or a DIY project that skipped the paperwork, unauthorised building works can cause significant stress. They can delay property settlements, void your home insurance, or result in compliance notices from your local shire.

To legalise these structures and comply with WA building regulations, you need to obtain a retrospective building approval.

We Simplify the Retrospective Approval Process

Retrospective approval is a speciality at Hills Building Consultants. As a fully Registered Building Surveying Contractor and Practitioner, we take the stress out of dealing with local councils. We have the local expertise to handle a wide range of unauthorised works, including:
  • Patios, pergolas and decking
  • Sheds and workshops
  • Shed-to-dwelling conversions
  • Retaining walls
  • House renovations and extensions

How Our Process Works

Navigating council regulations can be complex, but as your dedicated Building Surveyor, we manage the process from start to finish to ensure your property achieves compliance.

On-Site Inspection & Advice: Our process begins with meeting you on-site. We will inspect the unapproved works in person, assess them against current building codes, and provide clear, straightforward advice on exactly what is needed to achieve approval.

Specialist Coordination: In many cases, unauthorised structures require retrospective documentation. We work closely with you and coordinate with any necessary specialists—such as draftspeople and structural engineers—to gather the required evidence of structural integrity.

Certification & Council Lodgement: Once we have compiled the necessary documents, we will issue the required certification for council lodgement. Depending on the pathway required for your specific project, this may include issuing a BA18 Certificate of Building Compliance or a BA3 Certificate of Design Compliance.
