What Factors Influence the Cost to Build a Garage?

There are many factors that influence the cost of a garage, from size to siding. Keep in mind that all of these factors together will determine the final cost of your new garage.

The cost to build a new garage depends on the following factors:

  • Size: The square footage and how many cars you’d like to fit inside your garage

  • Material: The best garage material for you should fit your budget and the aesthetics of your home

  • Labor: Cost per square foot is different when using a standard material vs. using specialized material

  • Location: The cost in Missouri to build a garage is more affordable than the cost in California

  • Design: Depends on whether it’s an attached garage or a detached garage

  • Construction: The type of foundation makes a huge difference in the cost

  • Roof type: Asphalt shingles are popular and affordable while clay shingles can be on the higher-end

  • Siding material: Using vinyl is more affordable and durable than wood

  • Insulation type: An additional insulation layer in your garage will add to the final cost

  • Doors: The door size and whether it’s automatic or manual adds to the cost

  • Windows: They are not required but if you want to have natural light in your garage, it’ll add to the cost

Repairing vs. Building a New Garage

While the costs associated with repairing a garage are generally lower than the cost to build new, they can range widely based on what sort of repairs are needed. If your garage is not structurally sound, it may require costly updates to the foundation or framing. If your garage is structurally sound but needs some cosmetic repairs, you can expect costs to be considerably lower than building new.

Whether you repair or build new, you can expect labor to cost around $20 to $49 per square foot. Roofing, a common repair needed in older garages can cost between $1,600 to $16,000, depending on the size of your garage and whether you need to replace the insulation.

Older garages are also commonly in need of garage door repair or replacement. Most garage door repairs cost between $150 and $300 but replacements vary widely in cost. If you do have to replace your garage door, you’ll likely pay the same for materials and installation as you would if you were building a new garage.
