Typical costs for the construction of a new garage
According to Home Advisor, the nationwide average for paying a company to build an average-sized garage for you is about $25,000. That includes the total cost to design and build the new garage, including the materials plus the building permit. (To see costs just for the materials, click here.)
On the left below is a typical 2-car garage. In the photo on the right below, notice that an addition of a 1-car garage was later attached to the original garage. Building an attached 1-car garage like that will typically cost much less than the nationwide average.
So, is the size of your new garage the only factor in how much it will cost? No, there are many other issues (like whether the garage will be attached or detached).
Another factor in cost will be the construction material and the amount of additional insulation, if any. The garages with the lowest cost (and the least insulating) are metal garages. Next best is the standard wood or "stick-built" garage. Even better (in terms of better insulation but also with higher initial construction costs) is masonry block (or brick).
In fact, on the extreme of lowest costs, if the garage will be built by enclosing an existing carport that already has a roof and several walls, that will greatly reduce the total costs (plus construction time).
