The 2021 Code Conforming Wood Design (CCWD), a joint publication of the American Wood Council (AWC) and the International Code Council (ICC), is now available as a free download. The publication summarizes the key provisions related to the use of wood and wood products as they appear in the 2021 International Building Code (IBC).  

“The motivation behind the development of the CCWD is to provide code officials with a concise resource on basic requirements affecting wood use in the IBC,” said Philip Line, AWC Vice President of Codes & Regulations. 

 The 2021 CCWD details new code provisions from the 2021 IBC including: 

• Significant changes to Type IV construction with the introduction of three new types of mass timber construction (i.e., Type IV-A, Type IV-B, Type IV-C) and the renaming of the original Type IV as Type IV-HT.
• Revision of Section 506.2 on allowable area determination to include specific sections for single-occupancy buildings and mixed-occupancy buildings and introduction of Table 506.3.3 as a replacement to the weighted average calculation for frontage increase factors. 
• New requirements in Section 3313 for water supply to be provided prior to commencement of the above ground framing. 

“The main goal of the CCWD is to compile the occupancy and height and area provisions of the IBC for wood structures into one easy to use publication,” said Code Council Executive Vice President of Content and Services Mark Johnson. “We are pleased to partner with the American Wood Council to share this valuable information to aid in the safe and sustainable construction of wood buildings.” 

The 2021 CCWD, along with 2018, 2015, 2012 and 2009 versions, can be downloaded for free on the AWC website.
