This training document is an overview of the critical concepts of the 2003 International Building Code (IBC). These concepts provide a basis for the correct use of the code in the design, plan review, inspection and analysis of projects. A clear understanding and correct use of the requirements identified by these basic code provisions, tables and categorizations allows code users To apply the code in clear-cut situations, and helps To build understanding of the intent of the code when asked To make code compliance decisions.
