The average national cost to build a garage is $23,539, with most homeowners spending between $14,610 and $32,467.
When it comes to building a garage, a lot of factors come into play, which mimic other large-scale building projects. Garage construction costs come from a lot of different considerations and basically are determined by what the homeowner decides is most important. However, there are a couple of common categories that affect garage construction costs.
Attached versus Detached
Putting on an attached garage is more common and tends to be more affordable. Attached garages are building off of an existing structure, and can utilize that as a wall, which cuts down on the average cost to build a garage. It is also less expensive if the driveway is already in place. For a detached garage, the garage construction costs go up because it's building from scratch. However, these garages tend to offer more options, like a bigger work space.
As with more projects, size maters. The more square footage, the more materials and labor that go into the project. The size of your garage will depend on how many cars you want to fit, as well as if you want extra storage space or floor space for bicycles or other equipment.
The materials you choose will have a huge impact on garage construction costs. Upgrading the flooring to stain free or another higher-end floor, or adding a window, better roofing, designer doors, or a separate entrance can all add to the average cost to build a garage.
Sometimes homeowners opt to add an extra level to their garage, like an attic or suite above. These can even be used as an apartment. The addition will add to the overall garage construction costs, but it will help to increase the resale value of your home, so the overall cost per usable square footage goes down.
When thinking about garage construction costs, just remember that it's all in details. Once the size of the garage is decided, from there the average cost to build a garage lies in the smaller upgrades and whether or not you want to utilize the space above the garage. Some people opt to add custom organization, or hooks from the ceiling to increase storage space; others opt to add a guest bedroom or apartment. But your basic garage construction costs can be manageable if you stick to the basics.
