DCA5 DCA 5 - Post-Frame Buildings
Free Download - PDF
Provides guidance to post-frame building designers for meeting the requirements of the 2000 International Building Code and to confirm that a properly designed post-frame building is in fact code compliant.

DCA 6 - Prescriptive Residential Deck Construction Guide - 2009 IRC Version with May 2013 Addendum
Free Download - PDF*
Includes guidance on provisions of the International Residential Code (IRC) pertaining to single level residential wood deck construction. Provisions contained in this document that are not included in the IRC are considered good practice recommendations. Based on the limited number of changes to deck provisions in the 2012 IRC, the DCA6 2009 IRC version can be used in jurisdictions enforcing the 2012 IRC. The May 2013 Addendum contains new tables and other criteria to use with DCA6 based on changes to design values for all grades and sizes of visually-graded Southern Pine lumber effective June 1, 2013.

Learn about DCA 6* changes here.

Building officials may print a reasonable number of copies of DCA 6 for use with permits.

*Please Note: The entire DCA 6 cannot be posted to a building department website.

Updates and revisions are frequently being made to the document so it is recommended that building departments post a link (http://www.awc.org/codes/dcaindex.html) to DCA 6 on their websites. Also, AWC has developed a one-page PDF that can be posted to the jurisdiction’s website to provide an overview and links to the AWC document.
