Who typically has the authority to approve materials used in construction?

The building official typically has the authority to approve materials used in construction because they represent the local government or jurisdiction responsible for enforcing building codes and regulations. This oversight role ensures that all construction materials meet the necessary safety and quality standards required by law.

Building officials assess whether the materials comply with applicable codes and standards, which may include requirements set forth by national, state, or local regulations. Their approval is essential because it ensures that construction practices adhere to the established safety protocols, protecting both the integrity of the structure and public safety.

While contractors and special inspectors play crucial roles in the construction process—contractors by executing the work and managing supplies, and special inspectors by monitoring specific aspects of construction—the ultimate responsibility for approving materials lies with the building official. Architects also contribute significantly by selecting and specifying materials in their designs, but they do not have the final authority to approve them. Therefore, the building official is the key figure in ensuring that materials used in construction are compliant and safe.
