This publication covers material that applies to communities or states that utilize the IBC rather than the International Residential Code® (IRC®), and is designed for the convenience of homebuilders, design professionals, building officials and others involved in the design and construction of detached one- and two-family dwellings. Although many similarities exist between the two codes, this document covers the important differences inherent in the development of two separate documents with varying scope and application. 83 pp.
