Renovation Contracts in Victoria: What to Check Before Signing

Before you read a single clause, verify the fundamentals. These take ten minutes and they filter out most problem scenarios before they start.

• Builder registration: Domestic building work over $10,000 in Victoria typically must be carried out by a builder registered with the Victorian Building Authority (VBA). Check the registration number on the contract against the VBA public register, and confirm the registration class covers the work being done.
• The contracting entity: The name on the contract should match the registered entity, not a similar-sounding trading name. If the quote came from one company and the contract names another, ask why before signing.
• A written contract at all: For work over $10,000, a compliant written contract is not optional. A quote with a signature line is not a major domestic building contract.
• Domestic building insurance: For work commonly valued over $16,000, the builder typically must provide domestic building insurance before taking a deposit. Ask to see the certificate naming your property and your contract value.

If any of these basics are missing or vague, stop. A professional builder handles this paperwork routinely and will not be offended that you checked.

Victorian law typically caps deposits on major domestic building contracts: commonly a maximum of 10% for contracts under $20,000 and 5% for contracts of $20,000 or more. A builder asking for a 20% or 30% deposit on a $60,000 renovation is asking for something the framework does not generally allow, and that alone tells you how they treat compliance.

Progress payments deserve just as much attention. On renovations, payment stages are often negotiated rather than fixed, so check that each stage is tied to defined, verifiable work on site rather than calendar dates.

• Stage descriptions: Each claim should describe completed work you can physically see, such as demolition complete, rough-in complete or waterproofing complete.
• Front-loading: Be cautious when early stages claim a large share of the contract price before much work exists on site. Payments should broadly track the value of completed work.
• Final payment: A meaningful final stage payable at completion protects you. If the builder is fully paid before the last fix-off and defect items, you lose practical leverage.

None of this is about distrust. It is about keeping payment risk and work-in-place roughly aligned for both parties, which is exactly how experienced builders prefer to run projects anyway.

The single biggest source of renovation conflict is a gap between what the homeowner imagined and what the contract actually describes. Contracts are read literally when things go wrong, so the description of the work needs to be specific.

• Named products and finishes: The contract or its attached specification should name tile ranges, tapware models, cabinetry finishes and appliance selections wherever they are decided. A line that says allowance for tiles tells you very little about what arrives.
• Prime cost and provisional sums: These are legitimate tools for undecided items, but each one is a soft spot in the price. Check that the allowances are realistic for the quality you expect, because you pay the difference when they run over.
• Drawings and documents: Every drawing, engineering document and specification the price relies on should be listed in the contract and version-referenced. If it is not attached or listed, assume it is not included.
• Exclusions: Read the exclusions list as carefully as the inclusions. Painting, waste removal, appliance installation and making good adjacent rooms are common gaps.

A useful test: could a stranger read the contract and price the same project? If not, the document is not ready to sign.

Renovations of existing homes almost always involve some change once walls are opened, so the variation clause will get used. Check how it works before you need it.

• Written variations: Victorian contracts typically require variations to be documented in writing, with the cost and time effect stated, before the varied work proceeds. Verbal agreement on site is how disputes are manufactured.
• Who can request changes: Confirm the process for owner-initiated changes versus builder-initiated changes, such as those triggered by unforeseen site conditions.
• Extensions of time: Understand what events entitle the builder to more time, such as weather, variations or delays in owner selections, and how you are notified.
• Delay damages: Some contracts include liquidated damages payable to the owner if the build runs past the agreed completion date without a valid extension. Check whether the figure is meaningful or a token amount.

The goal is not a contract with no variations. It is a contract where every variation leaves a paper trail showing what changed, what it costs and what it does to the finish date.

Major domestic building contracts in Victoria typically include a five business day cooling-off period, during which you can withdraw with only a small administrative deduction in most cases. If you feel pressured to waive it or rush past it, treat that as a signal.

Victorian law also implies warranties into domestic building contracts that generally cannot be signed away. These commonly include warranties that the work will be carried out in a proper and workmanlike manner, comply with the plans and specifications, comply with legal requirements, use suitable materials and be fit for purpose where a purpose was made known.

• They travel with the home: Implied warranties typically benefit subsequent owners as well, which matters if you sell.
• They sit above the contract: A clause claiming to exclude these warranties does not generally remove them, but a builder who drafts such clauses is telling you something about their approach.
• Dispute pathway: If things do go wrong, Domestic Building Dispute Resolution Victoria (DBDRV) is typically the first formal step for domestic building disputes before VCAT.

Understanding these protections changes how you read the rest of the contract. You are not negotiating from zero; you are checking that the document respects a framework that already exists.

The contract should make responsibility for approvals explicit rather than assumed.

• Building permit: Confirm who is applying for the building permit, who pays for it and whose name it is issued in. For contracted renovation work, the builder commonly manages this through a registered building surveyor.
• Planning permit: If the project needs a planning permit from council, such as for some heritage overlays or external changes, confirm it is obtained before the contract locks in dates and prices that depend on it.
• Domestic building insurance: As noted above, this typically applies to work over $16,000 and protects you in limited circumstances, commonly if the builder dies, becomes insolvent or disappears. Verify the certificate before paying a deposit.
• Public liability and works insurance: Check the builder holds current public liability cover and clarify who insures the works and existing structure during construction.

None of these items are exotic. They are the standard scaffolding of a compliant Victorian renovation, and a contract that leaves them unaddressed is incomplete rather than flexible.

Pulling it together, here is a routine that takes an evening and prevents most contract-driven problems.

• Verify the builder's VBA registration and the contracting entity name.
• Confirm the deposit respects the typical statutory caps and the payment stages track real work.
• Read the specification and confirm every product you care about is named, not allowed for.
• Check every drawing and document the price relies on is listed in the contract.
• Read the variation, delay and extension of time clauses as if you will need them, because you might.
• Sight the domestic building insurance certificate before paying anything.
• Use the cooling-off period to have the contract reviewed if anything feels unclear.

A good builder will walk you through all of this without being asked, because a clear contract protects both sides. If the process of checking the document creates friction, you have learned something valuable before the first wall was touched.
