Dubious deck structure


what do you mean by 'Dubious deck structure'
A picture of your deck would certainly help.
I guess the department only looks at safety aspects and not estethic. This means that joists spacing should be 20" - 25" and deckingboards with a 5mm spacing. I am not sure, maybe footings are rotten, loose, connections between the joists, you need to be more specific. There is also a checklist in the buildingcode so then you will be able to check which items are dubious

Dubious deck structure


Would this beam splicing detail pass as dubious?

Probably not, but a easy and similar solution is probably available. Are you in Seattle, or "Seattle"? It would be nice to see an itemized list of the decks shortcomings.

1) How do you know it doesn't have footings?
2) While a ledger is nice, there is a rim back there. Your attachment may be structurally sound, and weather proofing may be the major issue.
3) What do you mean by 5" gap on the stair treads?
4) It is not uncommon for decks to not be included in the permitting process of Seatlle or the surrounding area, untill recently.

Dubious deck structure


A list of the defects, and I understand that not all of these may have been required by code at the time of construction:

1) The beam splice details are wrong
2) The deck has a ten foot span, but is framed using 2x8's
3) There is no diagonal bracing
4) The ledger is actually just a 1x10 which is part of the siding. This detail exists all around the house, not just where the deck is attached.
5) The posts aren't sat on proper bases (I meant base, not footing in my earlier posts).
6) The deck is attached to overhanging structure
7) The deck has a 3 foot overhang on a section of deck where the joists are only 8 feet long.
8) The space between the stairs allow the passage of a five inch sphere.

I want to waterproof the space under the deck using one of the interlocking aluminum board systems. This requires the deck structure being graded for run-off. For this I would need to pull off the stairs (which I would replace anyway with the aluminum boards), and I'm unsure as to what effect the regrade would have on the integrity of the existing joist hanger connections.

Since I would be going to all this effort, I thought it best to take the extra time to get all the structure up to code which will mean a total redo of the deck structure, but means it won't turn up to bite me in the ass if and when we come to sell the house. Thanks to everyone who has offered to provide fixes for the wrong details, but I think that if I went the 'fixing' route I would just end up with a Frankensteins monster of a deck, given the scope of problems.

I have started a few other threads on other aspects of this deck, and this thread was more concerned with the legal aspects of the work done by the previous contactor.

I am currently in the process of designing the new deck, in conjunction with a structural engineer and the permit dept.

Thanks to all who have helped me out here!

Cheers
Chris

Dubious deck structure


okay the picture explains a lot, I am not aware about local seatle regulations, however here in my country we have a building engineer make the technical drawings and he obtains the permits. He is also responsible for future failures.
The other comment here made was about liability or transferability of the contractor (you want to make a claim with the contractor), the previous homeower is the contracting party with the original installer, and so you can only make a fuss with the the previous owner to my opinion.
Since you can make a claim only a long time after the sale of the house is only possible with a 'hidden' failure. According to your photo this is not hidden but clearly visible. Anyway, this is the law here, maybe in your country/ state/ city it is different.
Technically seen, if the juntion is vast and stable and has not moved over time I guess an engineer would approve this kind of construction.
