Hey all, inspection student here,
I just finished the deck inspection class which I noticed said that ledger strips holding up joists are okay: https://education.nachi.org/show.php?course_id=61&element_id=1440
Does anyone know if they changed that in the 2018 IRC?
I found this:
R507.5.1 Joist bearing. Joist bearing shall be provided in accordance with Section R502.6 and fastened to the beam in accordance with Table R602.3(1) and to the joist hangers per the manufacturer. Joist hangers shall have a capacity as specified in Table R507.5.1.
This makes it sounds like every joist attached to a beam MUST be attached with a joist hanger. If that’s the case, a ledger strip alone would not be enough to support the joists. Or am I misreading here?
If true, do we need to change the training materials in the class? Also, how would you address this in a report?
