Overview of the IBC

The International Building Code (IBC) is the foundation of the complete Family of International Codes®. It is an essential tool to preserve public health and safety that provides safeguards from hazards associated with the built environment. It addresses design and installation of innovative materials that meet or exceed public health and safety goals.

Benefits of the IBC:

  • IBCThe principles of the IBC are based on protection of public health, safety and welfare.
  • The IBC results in efficient designs that provide flexibility for the code official, designer, engineer and architect.
  • Provisions of the code encourage the use of new and smarter technological advances.
  • The IBC emphasizes both prescriptive and engineered solutions and allows the use of time-tested methods.
