True or False: Upon notification from the permit holder or his agent, the building official must make any necessary inspections for on-site construction.

In the context of the International Residential Code, the statement is true because building officials are mandated to perform inspections on-site as part of their responsibilities to ensure compliance with the code and regulations. When the permit holder or their agent notifies the building official, it triggers the obligation for the official to conduct the necessary inspections, which are essential for verifying that the construction is being carried out according to approved plans and codes.

This requirement helps to ensure that any issues are identified and addressed promptly, thus safeguarding public safety and maintaining the integrity of the building process. The role of inspections is critical throughout the different stages of construction, and timely notifications enable the officials to fulfill their duties efficiently.

Other options would not accurately reflect this requirement. For instance, stating that inspections only occur if prior notice is given or are limited to only residential projects discounts the obligation of building officials to respond to notifications regardless of type or prior arrangements, which is not in line with how proper inspections are mandated within the code.
