FJ requirements for for a spa on deck?


Does anyone know what would be needed to support a hottub 7'x7'x36". The weight when full will be 4500 lbs. That's a 90 psf load.

The hottub will sit on a platform below the deck so that the top of the hottub will be at deck level. The platform is about 2 feet off of the ground.

I had planned on using a 3-2x10 band with 2x10 fj 12" o.c. for the 7'x7' platform. The posts will be 6x6 posts with a 16"x16"x16" footing on each of the four corners.

Is this going to be sufficeint or is it way to much? Do I have to use joist hangers or could I simply use a ledger strip and notch the bottom of the joists to sit on the ledger?

You essentially need to build it so it is freestanding from your main deck, and self-supporting. Structurally, they won't need to tie together, but you can utilize the existing deck somewhat for lateral support of the new structure. I would think that the joist system you're proposing would be adequate, but you should check with the local inspector to run it by him. The prescriptive measures and span charts in the code don't cover this. You'll need for your posts to directly bear the weight of the 3-2x10 beam...Not side-loaded and bolted. I would suggest joist hangers over the proposed notching and ribbon. Joist hangers, properly installed, will be much stronger.

And, if you're in indiana, a 16" deep footing will be inadequate. Here in Kansas, the code required frost depth is 36". I imagine it is easily that deep up north.
