Which type of buildings are exceptions to the requirement for special inspections according to the IBC?

Group U occupancies that are accessory to residential occupancy are specifically noted in the International Building Code (IBC) as exceptions to certain requirements for special inspections. These types of buildings, usually garage structures, sheds, or similar accessory buildings, are perceived to have a lesser risk in terms of structural issues or safety concerns when they are tied directly to a residential occupancy. Therefore, the IBC allows for some flexibility in the inspection requirements for these structures, given their scale and usage.

This exception helps streamline the building process while still maintaining adequate safety standards for more critical structures. In contrast, high-rise commercial buildings, industrial facilities, and historic preservation projects typically involve more complex construction processes and materials, necessitating more extensive special inspections to ensure compliance with safety and performance standards set forth in the IBC.
