Secure Your Certificate of Compliance for Illegal Building Works with CODE HQ

Discovering unapproved or non-compliant building works can feel overwhelming, but you’re in the right place. CODE HQ specialises in navigating Victoria’s building compliance requirements, helping homeowners quickly and confidently resolve issues and secure the proper certifications. With expert guidance and a clear, structured process, we make it easier to move forward with certainty.

Why a Certificate of Compliance is Important

Understanding Unapproved or Illegal Building Works

Illegal building work is a building work that required a building permit but was carried out without one, or work that deviates from the approved plans or permit conditions.


Compliance is achieved via assessment and certification by the Relevant Building Surveyor—this is not a “back‑dated permit,” but a formal pathway to recognise the work, verify it meets the required standards, and document compliance.

Situations Where a Certificate of Compliance is Needed

  • You’ve received a Building Notice/Order about works done without a permit
  • Preparing to sell or refinance and conveyancers/banks flag missing approvals or final certificates

Risks of Ignoring Unauthorised Works

  • Financial penalties for breaches of the Building Act 1993; prosecution possible for failing to comply with orders - Building Act 1993.
  • Notice to Order - Escalation from Notice to Order, including Stop Work or Emergency Orders; potential direction to demolish or rectify.
  • Sales can fall through; lenders may refuse refinance; insurers may decline claims related to unauthorised works.
  • Non-compliant structures may pose risks to occupants and visitors, exposing owners to liability.

FAQs

What is a Certificate of Illegal Works and why do I need one?

A Certificate of Illegal Works is a formal document issued by a Registered Building Surveyor confirming that previously unapproved building work has been assessed, rectified where required, and now fully complies with the Building Act and Regulations.



It protects you from enforcement action, supports insurance and finance requirements, and ensures a smooth property sale in the future.

What types of building works require a certificate?

Any structure or alteration that was built without the required building permit may need a Certificate of Illegal Works. Common examples include:


  • Decks, verandah, and pergolas
  • Carports, garages, and sheds
  • Room additions and sunrooms
  • Internal wall changes
  • Pools, spas, and associated safety barriers
  • Retaining walls and structural landscaping
  • Structures that have been repurposed (such as converting a garage into a bedroom)

What documents or evidence are needed for certification?


In all cases, we’ll require drawings from a registered draftsperson or architect and engineering to confirm the work are safe and compliant. No two properties / building works are the same the documents needed depend on what was built and how it’s being used.

What happens if I don’t obtain a Certificate of Illegal Works?

In all cases, we’ll require drawings from a registered draftsperson or architect and engineering to confirm the work are safe and compliant. No two properties / building works are the same the documents needed depend on what was built and how it’s being used.

Can I sell my property if it has illegal works?

While selling is possible, illegal works can reduce buyer confidence and lead to price reductions, withheld funds, or postponed settlement.



Certifying the works early helps protect your property value and avoids last-minute complications.

Can Code HQ help if I’m unsure whether my building work is legal?

Absolutely! We can review the constructed building and advise whether a building permit was required, and let you know exactly what approvals are needed, if any.

How do clients know they’re fully compliant afterward?

  • All documents and certificates provided
  • Clear evidence that the works now meet building regulations
