Proper Flashing
5 Attachment(s)
I have a 3' overhang on the back of my house (2nd story overhang over 1st story). Below the overhang is a concrete slab. I would like to enclose the overhang and make it an outside closet/storage area. How exactly would I do this?

I understand the framing part, my big question is how do I attach to the slab? Do I just bolt the bottom plate into the concrete slab or should I have something else there at the transition (row of brick)? The exterior will be siding. Seems to me that i would not want siding going all the way down to the slab but maybe with proper flashing that is ok?

It will be inspected, but my inspector isn't very knowledgable/helpful.

In a northern climate, if attached to the house then frost footers will probably be required.

If not, then bolted to the slab may suffice.

Not sure how code looks at that.

Too many variables, do you have stucco, wood siding, crawl space, slab-on-grade etc?

Sorry, I am located in Pittsburgh, PA.

The exterior is (will be) vinly siding. The slab runs under the current wall to the garage on the other side.

Nothing under slab.

Where I live, if its attached to the house, it requires a building permit. In Pittsburgh its likely that you will have to have a foundation with footings below the frost line.

You should check with your building dept. and see what is required in your area.

Here, if its free standing, it can be mounted on the slab. If its less then 100 s.f. and is free standing, no permit is required.
