What are the building code requirements for notching and boring holes in a wall stud?
Tuesday, June 19, 2018
The photo above shows how not to notch studs, especially since it was at a bearing wall. The International Residential Code (IRC) and the Residential Edition of the Florida Building Code (FBC) have separate standards for bearing and nonbearing walls, as shown below. Maximum of 25% notch in bearing wall and 40% in nonbearing wall; 40% bored hole in bearing wall, and 60% in nonbearing wall. Bored holes must be minimum of 5/8” from face of stud. An exception is allowed for up to a 60% bored hole for maximum of two successive studs in a bearing wall if they are doubled-up.
