Deck support barely adequate?

[Gerald C. Wilcox]

Today's deck 12x20. The horizontal ledger board was a single 2x6 lag screwed into the 4x4. Shouldn't it at least have been doubled one on each side of the 4x4 and bolted through? All the support to the deck joist is depending on the lag screws.

Absolutely.

Daaaamn.....I'll bet there is no permit on file (w/ municipal) for this deck installation. If there is a permit, it wasn't built to specs.

And look at the railing system. Another Wow!!!

I am positive Dave there was no permit pulled on that one.

Yea, I can see the first deck party now.

Call an ambulance for standby.

Let's just hope they don't decide to have a Winter bash when there is 3 feet of snow on it.
North Dakota.
My older brother was stationed in Minot many years ago. Bad Winters.

The 4x4's continue through the decking and are part of the guardrail system. Actually it was strong an no movement. The 12ft span on 3 4x4's bothered me. The 2x6 ledger actually is butted together at the center support.

Last year we had a tough winter, lasted 7 months. Lots of snow.......Lots of cold -30 actual with -50 wind chill. Not a practical choice for the homeless. But this deck survived.

No. Girders should bear directly on posts.
