Structural integrity?

Hello. This is a brand new deck system as of 2 months ago. I noticed that not only were 2/3 horizontal supports off center, but also, 2 joist hangars are snapped.

I live in MN and this is the code requirements
https://www.dli.mn.gov/sites/default/files/pdf/res-decks.pdf

I contacted the builder and he said the support posts didn’t move (despite obvious slide marks) or shift. He also said it was nailed on the end where the broken joists are and it was done so to make it straight.

It seems it isn’t or wasn’t square to begin with and should a single 6” x 6” horizontal support been used rather than 3 2” x 6” ’s?

Vertical and horizontal cracks on wood too?

Thanks for feedback.

Thanks for the feedback all:

Seeing as work needs to be done, several questions:

  1. What is the best way to lift the deck platform to add/adjust horizontal beams?
  2. The builder insists the vertical supports didn’t move, what else would explain the misalignment?
  3. Best way to secure end/mid posts attachment is Simpson Ties?
  4. Do the 3 horizontal beams need to be bound together?
  5. Anything else besides the obvious?

Appreciated much!

That is NOT up to code in my area. Beams aren't allowed to stand on the top of a post like that. They have to be installed in a way that they won't roll over.

Did you pull a permit to get this built?

It’s allowed in my area but requires the post to fully bear the beam and a connector to be used from post to beam
