A modification to incidental accessory occupancies (Table 508.2.5) has been made to the 2009 International Building Code (IBC). Parking garages and storage rooms are no longer regulated as incidental accessory occupancies.

A modification to loading conditions on cantilevered decks (Section 1604.8.3) has also been made in the 2009 IBC. Previous code language had been modified to address the situation in which the load on the cantilevered portion of a deck span could produce uplift at the support remote from the support at the cantilever, which is consistent with the intent of the distribution of live loads in Section 1607.10.

The Significant Changes to the 2009 International Codes series has been developed by the International Code Council and published by Delmar, Cengage Learning to accommodate the transition from the 2006 to the 2009 editions of the International Codes.

Valuable resources for anyone using the International Codes, each book offers a comprehensive yet practical analysis of the critical changes made between the 2006 and 2009 editions of the codes with hundreds of photos, illustrations and tables. Changes are identified then followed by in-depth discussion of how the change affects real-world application. Coverage reflects provisions with special significance, including new and innovative design ideas and technologies, modern materials and methods of construction, and current approaches to safety and stability. Authored by ICC code experts, these useful tools are "must-have" guides to the many important changes in the 2009 International Codes.
