ABOUT THE BOOK

The 2018 International Residential Code for One- and Two-Family Dwellings (IRC) is a comprehensive technical reference developed by the International Code Council (ICC) for professionals involved in residential construction, building design, inspection, and code enforcement. It establishes essential requirements for the construction, alteration, and safety of one- and two-family homes and townhouses up to three stories in height.

This edition brings together building, plumbing, mechanical, fuel gas, and electrical provisions in one coordinated code. It covers important areas of residential construction, including building planning, foundations, floor systems, wall construction, roof assemblies, chimneys, fireplaces, and energy efficiency. Dedicated sections also address heating and cooling equipment, ventilation, duct systems, water supply, drainage, plumbing fixtures, electrical wiring, lighting, and appliance installations.

The 2018 edition incorporates several significant technical updates. These include revised seismic design maps, updated townhouse fire-separation options, changes to emergency escape and rescue opening requirements, revised smoke alarm interconnection provisions, and updated structural tables for wood framing. These changes help professionals understand the code requirements and apply appropriate safety measures during residential building projects.

The book also includes extensive appendices covering subjects such as manufactured housing, radon control, private sewage disposal, patio covers, existing buildings, sound transmission, tiny houses, strawbale construction, and solar-ready provisions. Its organized chapters, technical tables, definitions, and referenced standards make it a practical resource for locating specific construction requirements.

Whether used by architects, engineers, contractors, builders, inspectors, code officials, or students of building trades, this reference supports a clearer understanding of residential building regulations and construction safety practices. It is a valuable professional resource for anyone working with residential building codes and compliance requirements.

ABOUT THE AUTHOR

The International Code Council (ICC) is a leading global nonprofit organization dedicated to developing building safety codes, standards, and professional resources that help protect public health, safety, and property. Established in 1994, the organization was formed through the collaboration of three major regional code-development bodies: Building Officials and Code Administrators International (BOCA), the International Conference of Building Officials (ICBO), and the Southern Building Code Congress International (SBCCI).

ICC develops the International Codes (I-Codes), a coordinated family of model codes covering residential and commercial construction, fire prevention, plumbing, mechanical systems, energy conservation, electrical safety, and other important aspects of the built environment. These codes provide consistent minimum safety requirements for buildings and communities.

The organization works with building officials, architects, engineers, contractors, inspectors, manufacturers, and other industry professionals through an open, consensus-based code development process. Its work also includes professional certification, technical training, product evaluation, accreditation, and educational publications.

The International Code Council is widely recognized for its contribution to improving construction standards and promoting safe, affordable, sustainable, and resilient buildings worldwide.

As the publisher of the 2018 International Residential Code for One- and Two-Family Dwellings, ICC provides essential technical guidance for residential construction, helping professionals understand building regulations, structural requirements, and safety provisions for homes and townhouses.
