Choosing the right building contract can make the difference between a successful construction project and costly disputes. For property developers, homeowners, and industry professionals in Victoria, understanding the distinction between HC-7 and HIC-6 contracts is fundamental to protecting your commercial interests and ensuring project success.
These Master Builders Association Victoria (MBAV) standard form contracts serve distinctly different purposes within the construction landscape. The HC-7 contract governs new home construction, whilst the HIC-6 contract addresses home improvements and renovations. Each contains specific provisions, risk allocations, and compliance requirements tailored to their respective project types.
This comprehensive analysis will equip you with the commercial insight needed to select the appropriate contract structure, understand your rights and obligations, and navigate the complexities of Victorian building law with confidence.
Why This Topic Matters
The choice between HC-7 and HIC-6 contracts extends far beyond administrative convenience, it fundamentally shapes your project's legal framework, risk profile, and commercial outcomes. With Victorian building industry regulations becoming increasingly sophisticated, selecting the wrong contract type can expose you to unnecessary liability, compliance breaches, and potential disputes.
The Domestic Building Contracts Act 1995 (Vic) mandates specific contract requirements for different project types, making proper contract selection not merely advisable but legally essential for works exceeding $10,000. Recent amendments to Victorian building legislation have further emphasised the importance of using appropriate contract structures, with enhanced consumer protections and builder obligations now embedded within these standard forms.
Furthermore, these contracts determine crucial commercial elements including payment structures, variation procedures, insurance requirements, and dispute resolution mechanisms. Understanding their fundamental differences enables informed decision-making that aligns with your project objectives and risk tolerance.
Key Legal Points to Understand
MBA HC-7 Contract: New Homes Construction Framework
The MBA HC-7 contract specifically addresses the construction of new residential homes where no architect administers the contract. This comprehensive document governs the entire construction process from foundation to completion, incorporating extensive provisions for project management, quality standards, and completion criteria.
Key characteristics of the HC-7 contract include fixed-price arrangements with defined scope parameters, comprehensive building warranties extending beyond completion, and structured progress payment schedules aligned with construction milestones. The contract places significant emphasis on compliance with building codes, permits, and Victorian Building Authority requirements.
Risk allocation under the MBA HC-7 contract typically favours builders through extensive extension of time provisions, whilst providing homeowners with statutory warranty protections and completion guarantees. The contract requires builders to maintain appropriate insurance coverage and comply with all relevant building standards.
MBA HIC-6 Contract: Home Improvement and Renovation Governance
The MBA HIC-6 contract governs residential improvements, renovations, and extensions exceeding $10,000 where architectural supervision is not required. This contract addresses the unique challenges of working within existing structures, including discovery of unforeseen conditions and integration with existing building elements.
Unlike new construction contracts, the MBA HIC-6 incorporates provisions for working around occupied premises, managing disruption to existing services, and addressing structural discoveries that may impact project scope. The contract recognises the inherent uncertainties in renovation work through specific variation and adjustment mechanisms.
Payment structures under MBA HIC-6 contracts often provide greater flexibility for scope adjustments, whilst maintaining consumer protections through statutory warranty requirements. The contract emphasises compliance with heritage constraints, council requirements, and existing building integration challenges.
Comparative Risk Allocation and Commercial Implications
Both contracts contain comprehensive extension of time provisions favouring builders, though the specific triggers and implications differ significantly. MBA HC-7 contracts focus on construction delays and material supply issues, whilst MBA HIC-6 contracts address discovery of existing building defects and unforeseen structural conditions.
Consumer protection mechanisms vary between the contracts, with MBA HC-7 providing broader completion guarantees whilst MBA HIC-6 offers specific protections against cost escalation in renovation work. Understanding these distinctions is crucial for appropriate risk management and commercial planning.
Determining the Appropriate Contract Choice
Project type fundamentally determines contract selection. New home construction, including knockdown-rebuild projects, requires MBA HC-7 contracts, whilst additions, renovations, and improvements necessitate MBA HIC-6 agreements. The presence or absence of architectural administration can also influence contract choice.
Consider engaging legal counsel early in the project planning phase to ensure appropriate contract selection and customisation. Standard form contracts may require amendments to address specific project requirements, risk allocations, or commercial arrangements.
Essential Pre-Contract Considerations
Before executing either contract type, ensure all parties understand their respective obligations, particularly regarding variation procedures, payment schedules, and completion criteria. Verify that all necessary permits, approvals, and insurances are in place or clearly allocated within the contract framework.
Review extension of time provisions carefully, as both contracts contain broad builder protections that may significantly impact project timelines. Consider whether liquidated damages clauses adequately reflect your potential losses from completion delays.
Managing Contract Performance and Compliance
Establish clear communication protocols and documentation procedures to manage contract performance effectively. Both MBA HC-7 and MBA HIC-6 contracts require careful administration to ensure compliance with notice requirements, variation procedures, and payment obligations.
Monitor progress against contractual milestones and maintain comprehensive records of all decisions, variations, and communications. This documentation proves invaluable should disputes arise or if enforcement action becomes necessary.

Frequently Asked Questions
Question: Can I use an MBA HC-7 contract for a major renovation project?
Answer: No, MBA HC-7 contracts are specifically designed for new home construction. Renovation and improvement projects require MBA HIC-6 contracts, regardless of the project's scale or complexity. Using the wrong contract type can result in enforceability issues and compliance breaches.
Question: What happens if my renovation project uncovers structural issues not anticipated in the MBA HIC-6 contract?
Answer: MBA HIC-6 contracts include specific provisions for unforeseen conditions and structural discoveries. These typically allow for contract variations to address additional work, though the procedure for managing such discoveries must be followed carefully to avoid disputes over additional costs and time extensions.
Question: Do both MBA HC-7 and MBA HIC-6 contracts require domestic building insurance?
Answer: Yes, both contracts require domestic building insurance for work exceeding $16,000. This insurance protects homeowners if the builder becomes insolvent, dies, or disappears during the project. Only registered builders can arrange this mandatory insurance coverage.
