Holes & Notches in your Studs, Beams and Joists

We all have them in our homes: holes drilled in our wood studs, joists,and beams to pass through electrical wiring or HVAC ducts. And sometimes you need to notch that stud just so to fit your new plumbing pipes. Not only is it standard construction practice to alter studsand beams to allow for wiresand pipes, but it is actually permitted by the International Residential Code (IRC), the code governing residential construction in most states, New Hampshireand Massachusetts included.

Some holes or notches may look worse than they are, but some may have more of an adverse impact on the structure of your home than it appears. So the IRC provides limits,and we developed Standard Details to help you know if the sizeand location of the notchesand holes are acceptable. So before you (or your plumber or your electrician) start drilling your studs, beam, or joists, take a look. And if you’re not sure if your stud wall is load bearing or just a partition, give us a calland we can help!

These are just two of the dozens of Standard Details Team Engineering has developed visualizing the IRCand showing good construction practices. Stay tuned, as we are constantly developing more!
