From the Foreword: "The new FEMA Building Science Branch Building Codes Toolkit offers basic guidance and tools to help building owners and occupants learn about building codes and the process of making a building stronger against natural hazards. Building codes are the minimum design and construction requirements to protect the health and safety of building owners and occupants, and the public. In the past, building codes, how they are added into buildings, and their value to communities have only been understood by the technical community. FEMA knows it is also important for building owners and occupants to learn about building codes and how they protect lives and property."
