Is this loft construction safe for my needs?

Hello everyone.

I'm new to the site. I'm hoping you can help me out as I just completed a loft and shelves in my little shop that I built last winter. After completing it, I realized that perhaps I should have done things a little differently, even though it seems of sound construction.

Here are some factors as you will be able to see in the pictures:

I used 2x4's for the joists and they are 9.5 feet in length.
The joists are 12 inches apart within 6 feet
The joists are NOT placed on top of the double wall plate. I did this because I wanted a little more room up top.
The joists are sitting on top of a 2x4 ledger, but are also tied into the wall with brackets.

I plan on storing a lot of things up in this loft, and maybe even having the kids camp out up there every now and then.

Is this sufficient strength, or should I have used 2x6 or 2x8 joists? If not, what are your suggestions to improve it?

Thanks in advance!

Luke

How heavy an item you plan on storing? On 12" centers I think your OK. A couple of kids bunking up there should be fine. Your roof rafters appear to be on 24" centers. I would not use those to support anything hanging from them. They should be OK for snow load but nothing more.

I would add a 2 X 4 vertical post at the outside corner of the cantilevered shelves.

Maybe one in the middle at the front.

I would agree with Norm if really heavy things are to be stored there. I did not suggest it because it looks like the span there is wall-to-wall and not cantilevered.

The middle support would be in addition to the corner support that I suggested.
