Building Disputes Victoria
Your rights and how to resolve them
Dealing with a building dispute in Victoria?
A building dispute can be one of the most stressful situations a homeowner faces. Whether your builder has delivered defective work, failed to complete the project, refused to honour warranty obligations, or simply disappeared — you have rights under Victorian law, and there is a clear process to resolve it.
At IOA Building Inspections & Consultants, we help Victorian homeowners navigate building disputes by providing independent expert assessments and reports. Our principal consultant Anton Molnar — a BPC-registered building practitioner (CB-L 16678) and Master Builder — has worked with hundreds of homeowners across Melbourne and regional Victoria who are dealing with the same issues you're facing right now.
This page explains how building disputes work in Victoria, what your options are, and how an independent building consultant can help you get the outcome you deserve.
What is a domestic building dispute?
In Victoria, a domestic building dispute is a disagreement between a homeowner and a builder (or building practitioner) about residential building work. This is governed by the Domestic Building Contracts Act 1995 (Vic), which sets out the rights and obligations of both homeowners and builders.
A domestic building dispute can involve:
- Defective building work — work that doesn’t meet the applicable building standards, the approved plans, or the requirements of the building permit
- Incomplete building work — a builder who has abandoned the project before practical completion
- Delays — a builder who has significantly exceeded the agreed completion timeframe without a valid reason
- Cost disputes — disagreements about variations, progress payments, or the final cost of the build
- Warranty claims — a builder refusing to rectify defects within the statutory warranty period (6 years for structural defects, 2 years for non-structural defects under the Act)
- Non-compliant work — building work that does not comply with the Building Code of Australia (BCA/NCC), relevant Australian Standards, or the conditions of the building permit
If you’re a homeowner in Victoria dealing with any of these issues, you are not alone — and the law is on your side.
How to resolve a building dispute in Victoria
There is a clear, structured pathway for resolving domestic building disputes in Victoria. Here’s how it works:
Step 1 — Try to resolve it directly with your builder
Before involving any external parties, put your concerns in writing to your builder. Be specific about the defects or issues and give them a reasonable timeframe to respond. Keep copies of all correspondence.
Step 2 — Get an independent building assessment
This is where most people realise they need professional help. An independent building consultant can inspect the work, identify every defect and area of non-compliance, and provide a formal report that documents the issues against the relevant building codes and standards.
This report serves two critical purposes: it gives you a clear, professional understanding of exactly what is wrong, and it provides the evidence you need if the dispute escalates to DBDRV or VCAT.
At IOA, we regularly prepare these forensically detailed reports for homeowners across Victoria. Our reports identify each defect, reference the applicable Australian Standards and BCA/NCC clauses, include photographic evidence, and provide an estimated cost of rectification. If you’re buying a property that may already have issues, a pre-purchase building inspection can identify problems before you commit.
Step 3 — Apply to DBDRV
If your builder won’t resolve the issues, you can apply to DBDRV for a free conciliation process. DBDRV is a government service that brings both parties together with an independent conciliator to try to reach an agreement.
Having a professional building report at this stage significantly strengthens your position. The conciliator and the builder can see exactly what the independent expert has found — it shifts the conversation from opinions to evidence.
If conciliation succeeds, the agreement is documented and can be enforced. If it fails, DBDRV issues a Certificate of Conciliation, which allows you to take the matter to VCAT.
Step 4 — Apply to VCAT
The Victorian Civil and Administrative Tribunal (VCAT) is where building disputes are formally determined if DBDRV conciliation doesn’t resolve them. At VCAT, you’ll need an expert witness report that meets the requirements of Practice Note VCAT 2 (PNVCAT2).
IOA prepares PNVCAT2-compliant expert witness reports and can attend the hearing to present expert evidence if required. Read more about our VCAT expert witness services.
Common building dispute scenarios in Victoria
Based on the hundreds of homeowners we’ve assisted, these are the most common building dispute situations we encounter:
Cracking in walls, ceilings, and brickwork
Cracking is one of the most common issues we see. It can range from minor cosmetic cracking to significant structural movement indicating foundation problems, inadequate footings, or roof truss deficiencies. We frequently see homeowners who have been told by their builder that cracking is “normal settlement” when it is actually well beyond the acceptable limits of AS 2870 (Residential Slabs and Footings).
Waterproofing and water damage
Leaking balconies, bathrooms, showers, and basements are among the most destructive building defects. Poor waterproofing can cause timber rot, mould growth, corrosion of structural steel, and extensive damage to internal linings. We identify the cause of the water ingress, assess the extent of resulting damage, and document it against the requirements of AS 3740.
Builder walked off or gone into liquidation
When a builder abandons a project or their company enters liquidation, you’re left with an incomplete build and potentially significant hidden defects. Our inspection documents exactly where the build is up to, identifies defects in the completed work, and provides a cost estimate for completion and rectification.
New home defects within warranty
Even brand new homes can have significant defects. Under the Domestic Building Contracts Act, your builder must rectify defects within the statutory warranty period. Learn more about our new construction inspection services.
Asbestos-related disputes
In older properties undergoing renovation, the discovery of asbestos-containing materials can lead to disputes over remediation responsibility and costs. Our asbestos testing services can provide the independent evidence needed to support your position.
Insurance disputes
Sometimes the dispute isn’t with your builder directly, but with your insurer. Our independent assessment can provide the evidence to challenge that determination.
Why you need an independent building report
- Evidence, not opinions — A professional report documents defects against specific building codes, standards, and regulations.
- Quantified rectification costs — Knowing the estimated cost to fix each defect is essential for negotiation, mediation, and any claim at DBDRV or VCAT.
- Protection against further damage — Some defects get worse over time. Identifying them early prevents escalation.
- Stronger negotiating position — Builders and their insurers take disputes far more seriously when facing a detailed, independent expert report.
