While requiring additional engineering for a specific material or its installation, the use of engineering means does not disqualify the remainder of the structure from the IRC code. These provisions and the associated limits will be addressed in a subsequent article in greater detail. The 2021 IRC® contains many important changes such as: Braced wall lines must be placed on a physical wall or placed between multiple walls.

2018 International Residential Code ( IRC ), with amendments, effective 01-01-2020, 19-11-102 (PDF). This comprehensive code comprises all building, plumbing, mechanical, fuel gas and electrical requirements for one- and two-family dwellings and townhouses up to three stories. As industry experts, we provide the codes and standards. Decades of knowledge and experience guide our code development process to create safe, sustainable and affordable communities and a level playing field for builders, developers and manufacturers. The IRC, by its nature, is generally considered a prescriptive code. This means that the code lays out direction for materials and installation methods of the structures under its jurisdiction. While a number of techniques and items are covered in the IRC, it does leave room for certain items to be used under a performance-based (or engineered) use described as “ alternative materials and methods” as illustrated in this article. More specifically, the IRC covers certain materials in a prescriptive way within certain limits. Once those limits are met or exceeded, engineering applications are typically required to address those materials, which can then be submitted to building officials for review and approval under the IBC. Look at the adopted codes for building inspections. The International Codes, or I-Codes, are the most trusted source of model codes and standards. Review original, unaltered versions of the IRC, IBC and other I-Codes or view specific versions adopted by a state and jurisdiction. Commercial decks attached to multi-family buildings, such as apartment buildings or businesses, are regulated under the International Building Code. Note that some local jurisdiction or state require higher, such as 42' in California. means the comprehensive stand-alone residential code that creates minimum regulations for one-and-two family. The IRC requires guardrails to be at least 36' in height, measured from the deck surface to the top of the rail.
