I am planning to build an addition to my house above my attached 2-car garage.The question is, will there be any problems with the slab on grade foundation ? Will any frost footings need to be installed?Or should I just build as planned?

First off, a building permit will be needed. This is going to be the key factor in what you are doing....BLUEPRINTS are requiired and this will show what the foundation is.

If the garage is attached to the home, I am assuming that what you have is sufficient for a 2nd story addition. Not knowing where you live, cold or warm climate, the attached garage means usually that you have frost footings. If the garage didn't, you would have severe heaving and thaw issues effecting the exterior of the home.

I really don't see any problems here but whoever is doing the drawings will access this to determine its feasibility.

Hope this helps!

Like Doug said we don;t know where you live. but I am willing to bet, that your footings are going to be a big problem. They usually are. Also, your roof, including your ceiling joists will have to be replaced, and it is possibel that additional strength in the walls will be required. Good Luck
