These dimensions are considered bare minimums.

All builders have a basic per-square-foot cost which they factor in the most basic framing and construction work.

Average national cost for a basic free-floating slab is about $2,000 to $7,000.

This cost can vary somewhat depending on the circumstances.

For example, if major excavation is required, costs can be higher.

Obviously, the fancier the garage doors, the more you should expect to pay.

Plan on doubling that cost if you are installing two doors in a double garage.

This cost does not include the garage door opener or any electrical wiring that must be done.

Of course, the number of windows you install will also increase the overall cost of your project.

Your garage will also need a side entry door, which is mandated by code in most areas.

You will pay more for more elaborate doors with glass panes, decorative panels, or fiberglass construction.

If you choose skylights, expect to add about $200 in time and materials for each cutout.

That’s usually because a homeowner ran out of money or a contractor skipped town.

Therefore, if you have a 600-square-foot garage roof you actually need 6 squares.

Nation averages are $80 and up including installation, by far the most common choice for garages.

There are also the costs of wiring and plumbing to consider.

Be prepared to spend some time identifying the pop in of garage you want and its features.

A nice garage will also be a strong positive if you someday decide to sell your home.
