Allowable Holes and Notches in Wood Joists

By Brian Ki, P.E.

There are very specific guidelines of where and how to drill holes and notches in conventional wood joists for plumbing and electrical. Taking out the wrong section of a wood member can lead to failure.

To help guide you on your next project and/or inspection, we’ve taken this detail straight from the 2015 International Residential Code. If you believe these guidelines were not followed on your project and would like one of our licensed Professional Engineers to inspect and/or come up with a repair solution for your home, give us a call today!
