Notching Posts – Is it okay?

Say “No” to notching pressure-treated deck posts. We want you to build an outdoor railing system that you, your family and guests can enjoy without worrying about safety issues. In order to do so, you need to know this building shortcut is not advisable, and we recommend avoiding it at all costs.
When you notch your railing posts, creating a lip that extends over the deck or porch boards, the outward thrust is significantly reduced. Unfortunately, notching railing posts is a practice we see time and time again.
Here’s why it should NOT be done:
Creates a weak point in the post
Vulnerable to cracking
Moisture creates issues between post and deck over time
Here’s a great visual representation to reference from Builder Online.
