This chapter is designated as “Reserved” for future use. The chapter previously contained provisions for the regulation of existing buildings. Section 101.4.7 was established in the 2015 IBC® to indicate that the International Existing Building Code is to be applied to all matters governing the repair, alteration, change of occupancy, and addition to and relocation of existing buildings. Chapter 34 is now considered as a placeholder for any future new chapter that may be added to the IBC.
