Foundation?

[fishfarmeat]

If I had a unattached garage that was poured on a slab without a block foundation could I attach the house and the garage with a three season breezeway? Any help or suggestions would be greatly appreciated. Also I live in the country with relaxed building codes.

how long has the garage been there?

I wouldn't do it. I have seen too many roof lines moving around with the freeze thaw cycles. I have a buddy that purchased a house(with a foundation) that had attached 3 season porch(without a foundation) and he had water running in where the roof line moved. That is just my experience with it.

Can be done but you'll have to keep some things in mind.

Knowing the distance would help. If you can post a picture that would help so we wouldn't have to list all the possibilities of what and what not to do.

I was going to do the same,BUT my frost heave of the garage is 1&1/2-2 inches the neighbors is up to 6 inches.The only way I could think of doing it, was not to attatch to the garage but let the walls and roof float,then there is a possibility of leakage from non attached roof valleys,but a water diverter on garage roof would help,lots of maybes,like dont attach roof to roof but nail flashing on both and hope it flexes and takes frost heave???????????

Have not built the garage yet. Was thinking of putting in the garage this year and would do a breezeway later. Garage would be less than 20 feet from the house.

If you have not built the garage yet, it's easy..

Frost footings!! That would be the best way to build what you want.

Frost footings for the garage would be ideal. I'd then not go with a 3 season breezeway. I'd turn that connection into an Entryway/Mud room with frost footings as well or floor trusses. A picture would help.

If the garage frost footings are out of the question then you can't connect the house to the garage. You can still have a breezeway though. You can do it free from the house and garage. Or you could tie into the house and use a frost footing next to(not tied in)the garage. Nothing structural can touch the ground between those two points and there'll need to be enough clearance for frost. You can make a slip joint from ground to wall though.

You could tie into the garage(not the house) but you can't be sure the frost heave at the garage will be the same away from it. In fact because or the heat loss around your foundation the ground won't heave at all. So that option doesn't have a constant and I would not go with it.

I agree with surface tension I have a mud room between my garage and house and love it . It not that much money to put in frost footing if you plan to attach.
