2018 International Residential Code for One- and Two-Family Dwellings by International Code Council

The 2018 International Residential Code for One- and Two-Family Dwellings is a comprehensive collection of prescriptive regulations and standards providing minimal requirements for the construction and remodeling of one- and two-family dwellings and townhouses up to three stories in height. It is widely accepted as the most up-to-date and comprehensive code of its kind. As an essential resource for local officials, builders, designers and remodelers, the 2018 International Residential Code (IRC) offers the latest regulations for the construction and inspection of one- and two-family dwellings and townhouses.

The 2018 IRC is organized by topic, making it easier to find and use the information relevant to your project. Its updated design, organization, and information-sharing capabilities will help minimize the time and complexity of the inspection and permitting process, helping you meet your project goals in a timely and cost effective manner.

The IRC works to ensure that the minimum regulations and standards for building and remodeling one- and two-family dwellings are met everywhere in the United States. It focuses on specifying practices that create safe and durable dwellings that are also energy efficient, accessible, and cost effective. The IRC addresses areas such as structural design, fire safety, sanitation, health, and energy efficiency.

The IRC works in tandem with other residential codes and standards to create a comprehensive set of building regulations. For example, the IRC coordinates with the International Construction Code (ICC) and International Existing Building Code (IEBC) to create unified construction and renovation practices.

The 2018 IRC provides important information on topics such as the building footprint and structural design, fire- and life-safety systems, mechanical and electrical systems, plumbing systems, energy efficiency measures, accessibility requirements and much more. It also includes measurement tools for areas such as occupancy loads, ventilation and egress requirements, equipment ratings and materials and equipment performance.

The 2018 IRC highlights the importance of using up-to-date codes and standards. It is a refreshing reminder that although older materials sometimes still work with newer systems and materials, sometimes they may make the most sense in certain applications.

By referencing the IRC and complying with its regulations and standards, one- and two-family dwelling designers, builders, and remodelers can be assured that their projects meet minimum requirements for safety, energy efficiency and cost-effectiveness. This helps ensure the long-term outcomes of their project, making the 2018 IRC an essential resource for any professional working on one- and two-family dwellings.
