Typical cost for Carport vs Garage

[Venky B.]

I have given an offer on a home which does not have a garage. I am planning to add a car port or a garage for a one car. I believe adding garage is expensive than adding a car port.  Can any one suggest, how much a carport will cost Vs adding a garage.

Thanks,

Venky

If you can attach it that is usually cheapest, as you avoid one whole wall and get to hang structural units from the house. Otherwise, it should be somewhere around 50-75% of local finished square feet.
