What must be done before making a material change to a permitted plan?

Before making a material change to a permitted plan, it is essential to notify and obtain authorization from the chief building official. This is crucial because the chief building official is responsible for ensuring that all construction complies with applicable codes and regulations. Material changes can affect various aspects of the project, including safety, compliance, and adherence to local zoning laws. Therefore, securing permission helps to maintain oversight and ensures that all changes are properly reviewed and approved, avoiding potential legal and safety issues.

The role of the chief building official is to assess the impact of these changes and determine if they still meet the required building standards. This process protects the integrity of the project and the safety of its occupants. Additionally, changes made without proper authorization could result in delays, fines, or even permit revocation, underscoring the importance of following the correct protocol.

Other options present different approaches that do not fulfill the necessary requirement of obtaining proper authorization from the chief building official, thus potentially leading to non-compliance with building regulations.
