What is a Master Builders Cost Plus Contract in Residential Building?

A Cost Plus Contract is a type of contract where the homeowner agrees to pay the builder for all the costs incurred in building the home, plus an agreed-upon margin or fee for the builder’s services. This type of contract is often used for custom home building projects where the scope of work and pricing can be difficult to determine upfront.

The Master Builders Association (MBA) Cost Plus Contract is a popular option for residential building projects in NSW. It is designed to provide greater transparency and flexibility in pricing, allowing for more open communication between the homeowner and the builder. This type of contract can provide greater control and flexibility in the construction process, but it can also be more expensive and require more trust between the parties.

The advantages of a Cost Plus Contract include greater flexibility in the construction process, as well as more transparency in pricing and a clearer understanding of the costs involved. However, the potential drawbacks include higher costs and more risks, as the homeowner assumes more responsibility for the cost of the project.

To ensure a successful outcome with a Cost Plus Contract, it is important to have clear communication and transparency between the homeowner and the builder. A well-drafted contract can help to clarify expectations and provide a roadmap for the construction process. It is also important to review the contract carefully and negotiate any areas that may be unclear or ambiguous.

How Does an MBA Cost Plus Building Contract Work?

The Master Builders Association (MBA) Cost Plus Residential Contract is designed to provide homeowners with greater transparency and flexibility in pricing for construction projects.

Under this type of contract, the builder charges the homeowner for all costs associated with building the home, plus an agreed-upon margin or fee for the builder’s services.

  • The cost-plus formula used in the MBA contract typically includes direct costs (such as materials and labour) plus indirect costs (such as overhead and profit margin). The homeowner is responsible for paying all costs associated with the project, including any additional expenses that may arise.
  • The MBA Cost Plus Contract includes several key features that are designed to protect both the homeowner and the builder. These include provisions for detailed invoicing and documentation of all costs, as well as clear communication about any changes or additions to the project scope.
  • One important limitation to note is that the builder is typically limited in the amount of margin that can be charged on top of the direct and indirect costs. This is to prevent excessive markups on the project and ensure that the homeowner is not charged more than is reasonable for the builder’s services.

Overall, the MBA cost-plus contract can provide greater flexibility and transparency for residential building projects, but it is important to carefully review and negotiate the terms of the contract to ensure that your interests are protected.

How Do You Protect Yourself if You're Using a Cost Plus Contract?

While a Master Builders Cost Plus Contract can provide greater flexibility and transparency for residential building projects, there are some common issues and risks that homeowners should be aware of.

  1. To protect your interests when using a cost-plus contract, it is important to have clear contract terms and conditions, as well as a plan for mitigating potential risks and resolving any disputes that may arise.
  2. One of the most important ways to protect yourself is to ensure that the contract terms are clear and well-defined. This includes clearly defining the scope of work, pricing and payment terms, and any other relevant details that may impact the project. It is also important to review the contract carefully and negotiate any areas that may be unclear or ambiguous.
  3. Another important consideration is to have a plan in place for mitigating risks and addressing any issues that may arise during the construction process. This may include setting up a system for monitoring progress and costs, as well as having a plan in place for addressing any changes to the project scope or any unexpected expenses.
  4. Finally, it is important to understand your options for resolving any disputes that may arise during the project. This may include mediation or arbitration, or taking legal action if necessary. Having a clear understanding of these options can help to ensure that any issues are resolved in a fair and timely manner.

By taking these steps to protect your interests, you can help to ensure a successful outcome when using a cost-plus contract for your residential building project.
