What must a builder do if they plan to change the original design during construction?

When a builder plans to change the original design during construction, obtaining a signed change order from the homeowner is essential. A change order is a formal document that outlines the specifics of the proposed changes, including details about how the changes will affect the project's scope, cost, and timeline. This process ensures that both parties are in agreement with the modifications, promotes transparency, and helps to avoid disputes down the line.

Having a signed change order also provides a legal record of the homeowner's approval, which is critical for protecting the interests of both the builder and the homeowner. In construction, clear communication and documentation are vital to maintaining trust and avoiding misunderstandings.

The other options lack the necessary formality and documentation that protects both parties involved in a construction project. Verbal agreements can lead to miscommunication, and proceeding without notification undermines the homeowner's rights. Keeping changes informal and undocumented can create significant issues if disagreements arise later regarding the work performed or the costs incurred.
