Which term describes the approved methodology of changing a building's use or structure?

The term that accurately describes the approved methodology of changing a building's use or structure is a change certificate. A change certificate serves as an official document indicating that a particular alteration, such as a change in use or the structure's configuration, has met all the regulatory requirements and has been formally approved by the necessary authorities. This ensures that the modifications comply with relevant building codes and zoning laws, thus preserving safety and community standards.

Building alteration refers to any change made to a structure, but it does not inherently imply that such changes have been officially approved or documented in a formal manner. A site survey typically involves assessing the land or site conditions rather than the specific approvals for building changes. Construction modification is a more general term referring to any changes made during construction, without the specific context of approval processes like those reflected in a change certificate.
