Mastering MBA Contracts in Melbourne, VIC: A Homeowner's Guide

An MBA contract is a standardised domestic building contract developed by the Master Builders Association. Your builder is not required by law to use an MBA contract — they may present you with an HIA contract, their own custom contract, or another industry form. However, many Melbourne builders favour MBA contracts for residential builds. Regardless of the contract type presented, you have the right to seek independent legal advice before signing. Under the Domestic Building Contracts Act 1995 (Vic), some contract terms are mandatory, and a specialist review ensures compliance and fairness.

Your fixed-fee cost disclosure is provided within 24 business hours of you confirming your interest. Once you accept and payment is received, your comprehensive MBA contract review report — including a Q&A consultation — is delivered within 2 business days. This fast turnaround ensures you have time to review and negotiate amendments before the builder pressures you to sign.

The Domestic Building Contracts Act 1995 (Vic) sets out mandatory requirements for all domestic building contracts in Victoria. Key provisions include: the contract must be in writing; a signed copy must be given to the owner before work commences; prime cost and provisional sum items must be disclosed; cost disclosure documents are required for certain projects; statutory warranties attach to all domestic building work; and homeowners have a cooling-off period after signing. An MBA contract review confirms your agreement satisfies all of these requirements.

Under the Domestic Building Contracts Act 1995 (Vic) and the Building Act 1993 (Vic), builders must warrant that: all work will be performed in a proper and workmanlike manner; materials will be good and suitable; work will comply with all laws and legal requirements; the work will be fit for the purpose for which it is required; the work will be completed within the time specified; and the land will be reasonably protected. These statutory warranties run alongside the contractual terms and cannot be contracted out of. Even where an MBA contract is silent or ambiguous on these points, the warranties provide important legal protection.

Most domestic building disputes in Victoria are resolved through the Victorian Civil and Administrative Tribunal (VCAT). MBA contracts typically include a dispute resolution clause requiring parties to first attempt to resolve matters through negotiation or mediation before proceeding to VCAT or court. The Building Act 1993 (Vic) also provides for compulsory conciliation through the Victorian Building Authority (VBA) for certain categories of dispute. Having your contract reviewed before signing ensures you understand the dispute resolution pathway that applies to your specific situation — and that any dispute resolution clauses are not unfairly loaded against you.

Yes. An MBA contract is a starting point, not a fixed document. Builders regularly accept amendments proposed by homeowners, particularly when those amendments are presented professionally and clearly justified. A contract review report provides you with specific, clause-level amendment recommendations — in plain language — that you can put to your builder. Amendments agreed before signing are far easier to achieve than after. This is why pre-signing review is the most cost-effective legal investment you can make for your build.

If you have already signed your MBA contract, we can still assist. Under the Domestic Building Contracts Act 1995 (Vic), homeowners have a statutory cooling-off period of 5 business days after signing, during which you may rescind the contract. If the cooling-off period has passed, we can review your signed contract to identify your rights and obligations if issues arise during construction. Even post-signing, understanding your contract positions you to manage your builder more effectively and respond to any disputes that may arise.

Prime cost (PC) items are materials or fittings that are not yet selected and for which an allowance is included in the contract price — for example, tapware or tiles. Provisional sums (PS) are estimates for work that cannot yet be precisely costed, such as earthworks or rock excavation. Both create financial risk for homeowners because the final cost may exceed the allowance. Victorian law requires prime cost and provisional sum items to be clearly disclosed in the contract. A review identifies whether these items are adequate — and whether the contract appropriately limits how and when the builder can claim additional amounts.

Early legal advice prevents expensive disputes. Even a well-drafted MBA contract may contain terms that, in the context of your specific project, expose you to cost blowouts, delays, or reduced recourse if defects emerge. Most homeowners sign without fully understanding their obligations and the risks embedded in even standard form contracts. A pre-signing review identifies these risks while you still have negotiating power. Problems that cost thousands — or tens of thousands — to resolve through VCAT later can often be addressed with a fixed-fee review now. It is the most cost-effective legal investment you can make for your construction project.
