Home Builders' Jobsite Codes
Introduction
Introduction
Home Builders' Jobsite Codes is a field guide for builders, trade contractors, design professionals, inspectors, and others involved in the design and construction of residential buildings. It is based on the 2006 edition of the International Residential Code® (IRC), a comprehensive, stand-alone code that establishes minimum regulations for the construction of one- and two-family dwellings and townhomes, including provisions for
- structural design
- fire and life safety
- energy conservation
- mechanical systems
- fuel-gas systems
- plumbing
- electrical systems
The IRC's purpose is to safeguard public safety, health, and general welfare from fire and other potential hazards attributed to the built environment, while still providing for affordable homes. The code provides for strong, stable, and sanitary homes that conserve energy and yet offer adequate lighting and ventilation.
The IRC is published by the International Code Council® (ICC), maintained and updated through an open code development process, and is available internationally for adoption by the governing authority.
Home Builders' Jobsite Codes focuses on the prescriptive provisions of the IRC-"recipes," if you will, for meeting code requirements without the need for an engineered design. These provisions address all aspects of conventional construction of dwellings and their accessory buildings. Illustrations and tables assist the reader in understanding the code requirements and address frequently asked questions. Certain industry terms appear in italics the first time they are used in the text. Definitions of these terms are provided in the glossary at the back of the book.
This publication intends to serve as a guide only. It does not include all applicable requirements of the IRC. Engineered design based on performance criteria of the code, for example, is outside the limited scope of this publication. Builders should consult the IRC, local amendments, and local building departments for detailed requirements and other methods of construction. Discussion of structural requirements is generally limited to the prescriptive provisions for regions with wind speeds of no more than 100 mph and ground snow loads of 70 lb. per sq. ft. or less. It excludes earthquake design considerations.
Builders should obtain information on requirements for wind, snow, seismic events, flood, soil, or other conditions, as well as any amendments to the code, from their local building departments. Energy conservation, decay resistance, and termite control requirements also vary by geographic region.
In addition, please be aware that although this guide is organized into chapters similar to the IRC, there are some important exceptions. For example, for ease of use, IRC "Building Planning" requirements, detailed in chapter 3 of the code itself, are divided into three separate chapters in this pocket guide-structural design criteria, fire protection, and other minimum safety and health requirements. These important issues are explored in more detail in later chapters of
Home Builders' Jobsite Codes.
At the same time,
Home Builders' Jobsite Codes includes additional useful information not found in the IRC, such as weights of building materials and components.
