Which of the following is NOT a requirement for a home improvement contract?

In a home improvement contract, a detailed list of materials used is not a standard requirement. While it is beneficial for transparency and clarity regarding the scope of work, the law typically mandates that contracts must include certain key elements, such as approximate start and completion dates, the homeowner's signature to indicate consent and agreement, and the contractor's license number, which verifies that the contractor is legitimate and authorized to perform the work.

Including a detailed list of materials can be helpful in establishing the quality and type of materials being used, but it is not legally necessary to fulfill the basic requirements of a binding home improvement contract. Thus, the correct answer reflects the reality that while a list of materials might enhance the contract, it is not required by law.
