Installing pergola on raised deck.


Actually we did build the deck to fit the pergola structure. We had the same dilemma about the vertical posts then as we do now. We decided to build the deck making room for the 4 pergola posts to be added later when we solved the height issue. We haven't added rails pending the raising of the pergola structure.

The existing deck posts are 4x4.

I don’t see what the big issue is, go buy longer post.

Oh, and BTW your post to beam connections are not to code.

The issue for me is cosmetic. I still don't know why the deck wasn't built to accommodate the pergola.
You're right about those connections. Maybe he can bolt a short vertical 2x4 on either side of the post

I think the concerns from the general population here are:

1) You used 4x4 posts
2) You did not notch the post where the 2x joists connect creating the beam (which you can't do with a 4x4 post anyway)

Your first photo looks like pg 8: Figure 9. "Prohibited Post to Beam Attachment". And it should look like Figure 8.

I'm sure some folks will be reluctant to offer much help since there is a real concern about the integrity of the deck given those 2 points.

I think before moving forward with the pergola, you should concentrate on reinforcing the beams. Get 6x6 posts, notch the top, measure from the bottom of the beam to the top of the footing, add 1/4", jack the deck up, and put the right posts in. Once you have proper support for the decking, build the pergola right on top.

Good luck.

I still say bolting 2x4 blocks on either side of the post directly under the joists will work if the inspector allows it. I've built industrial buildings 60'x100' in this way with a 2x12 yellow pine spanning 12' between posts and then roof trusses resting on top of the 2x12s. Thats with a 40# snow load up here!

I will look for signs of stress or failure and if present will try adding blocks bolted on the posts under the beams. Thanks.

If you had your approved plans which is needed for your permit that you didn’t pull you wouldn’t be having these issues now.

No permits required where the deck was built and so far I am not having any "problems". All I asked originally was how to solve a post height issue.

And now for the third time I’m saying “buy longer post, go to a lumber yard and not a box store and buy your longer post”.

I looked at the attachment of the document, and it directly contridicts a floating deck consrtuction. Is this something doc for certain hieghts and sizes of deck?

So, I've seen supplies for attaching a 4x4 post to the top od a deck or concrete slab. If you feel secure about the deck construction, what is keeping you from putting the posts over the support posts? Then put your railings between them.

You see my previous post above...Floating decks only allow for a 4x4 post. There is no other way to attach the beams. Though, I am only 3' off the ground.
