Understand Code Bracing Requirements

What is bracing, and why is it so important?

A house must be built to safely resist the lateral loads during a high-wind event or an earthquake. Wall studs alone can't resist the racking forces. Wall bracing helps keep walls square during wind and earthquakes.

What are code requirements for wall bracing?

Wall bracing is one of the most important structural elements of any house, but it can also be one of the most confusing. The International Residential Code (IRC) defines eight bracing methods and two alternative methods and defines minimum widths for wall bracing segments based on the type of bracing method and construction material specified. Fully sheathing a house with wood structural panels is the only IRC-approved way to reduce the width of bracing segments to less than 48 inches. Most modern home designs feature narrower segments at garage, window and door openings, and it is important to follow the code requirements in these locations, including connection requirements to the foundation.

The wall bracing experts at APA – The Engineered Wood Association offer a free online course and publication, Introduction to Wall Bracing, Form F430, on wall bracing. These resources will clarify IRC requirements and answer common questions about wall bracing.
