Garage Material Prices

The average material costs to build a garage range anywhere from $15 to $40 per square foot. This works out at $5,250 to $14,000 for an average 350-square-foot garage. Remember, this does not include the cost of hiring a contractor or paying for building permits.

The costs vary considerably depending on whether you opt for a bare-bones model or a high-quality finish with an insulated interior, electricity, HVAC, and running water. Upgrading the flooring, adding windows or a separate entrance, or specifying better roofing or designer doors all add to the total build cost.

Some of the material costs to consider when building a garage include:

  • Framing costs: $3–$6 per square foot
  • Roofing costs: $1–$10 per square foot
  • Concrete slab costs: $4–$8 per square foot. It’s tough to get this one done with materials alone. You’ll need a concrete mixer and specialized tools to pour, level, and set the slab perfectly.
  • Drywall costs: $1.50–$3 per square foot or $12–$35 per panel. Attached units at least require fire-rated drywall on the wall or ceiling shared with living spaces.
  • Insulation prices: If you’ll be working in your garage rather than storing cars, you might consider adding insulation. Depending on the type you choose, it costs between $1 and $5 per square foot.
  • Window costs: $75–$1,500 per window depending on the materials, size, and style.
  • Foundation costs: Concrete slabs are a common foundation for a garage. Expect to pay $3 to $5 per square foot.
  • Garage door costs: Installing a standard garage door costs anywhere from $350 to $1,100. You could pay up to $10,000 for a high-end custom variety.

      Garage Installation Cost

      Typically, labor makes up at least 50% of garage construction costs (unless you opt for budget or very high-end materials). Expect to pay from $20 to $50 per square foot. Hiring a local general contractor is usually more convenient and cost-effective than hiring each specialist individually. They can bring in subcontractors to work on things like the roof, walls, siding, painting, and any electrics or plumbing.

      Garage Cost by Type

      The type of construction you opt for with your garage build can affect costs significantly. At the low end, prices start from around $25 per square foot, including materials and labor, while at the high end, expect to pay upwards of $120 per square foot.

      Brick or Brick Veneer Garage

      Expect to pay $27 to $45 per square foot or more to purchase the materials for building a garage made from brick. By the time you add in the labor, brick garage costs could be as much as $47 to $95 per square foot. Building solid brick walls is a labor-intensive method, and the bricks themselves don’t have any real insulating value.

      For a more economical and practical brick look over the top of a wood or metal frame, you could opt for a brick veneer wall instead. Also known as wythe, these are typically 4-inch thick bricks, and they cost between $10 and $30 per square foot. A thinner brick veneer (around 1-inch) typically costs $5 to $15 per square foot and is less heavy than wythe. If your home has brick siding, you can select a veneer for your garage to match.

      Stick-Built Wood Garage

      If you want to go with a unique shape or traditional carpentry, you might choose to have your garage stick-built with a lumber frame on-site, particularly if your home has the same type of construction. This framing style typically costs $40 to $70 per square foot for the materials alone and $60 to $120 per square foot including labor.

      Pole Barn Frame Garage

      A more economical option compared to stick-built frames, pole barn framed garage materials typically cost between $20 to $35 per square foot. Manufacturers build the prefabricated frames off-site and they take less time to construct. Including labor, you can expect to pay between $40 and $85 per square foot.

      Metal Garage

      You can build metal garages faster than wood or brick framed constructions, but they lack cohesiveness with your home. Also, you can't get a permit for these types of structures in every neighborhood, so you'll need to check with your municipality. Before adding on labor costs, expect to pay between $3,000 and $11,000 for a metal DIY garage kit.

      Cinder Block Garage

      Cinder block walls are a popular choice in areas prone to hurricanes or termites because they’re durable and easy to cover with siding or stucco. Expect to pay between $9 and $12 per square foot for cinder block wall materials and $29 to $62 including labor.

      Garage Installation Cost by Size

      The cost to build a new garage varies depending on the materials used and the desired finish. For a basic build, expect to pay from around $40 to $70 per square foot. High-end builds with electrical and plumbing upgrades could end up costing as much as $120 to $350 per square foot.

      The width and depth of your garage will play a large part in how much you spend on your build, so consider carefully how much space you really need before commencing the project.

      Below are some indicative prices for some of the most common garage sizes.

      1-Car Garage

      For a basic one-car garage with no additions, expect to pay between $10,500 to $27,000. These typically measure 12 to 16 feet wide and 20 to 24 feet deep. For a 1.5-car unit providing a little extra storage space, a basic build could cost up to $32,000.

      2-Car Garage

      Double garage costs range from around $14,500 to $40,300. These are 22 to 26 feet wide and 20 to 24 feet deep.

      3-Car Garage Cost

      Average costs for a basic 31 to 34 feet wide 3-car garage range from $28,200 to $57,100

      4-Car Garage

      The costs for a 4-car garage typically range from $32,000 to $73,900. Adding HVAC, plumbing, and a workshop could raise the costs to over $100,000.

      RV Garage Cost

      To house RVs, you’ll need a door no less than 14 feet wide and 12 feet high, and a single bay will need to be at least 40 feet deep. Prices can range from around $36,000 to $140,000. You could even spend more if you want to install RV hookups for things like electricity and water or a complete sewer system.

      Building a Garage Cost Factors

      As well as the garage size and materials used, various other factors can influence the cost of the build. 

      Attached vs. Detached Garage

      If you’re building a garage attached to your existing home, expect to pay 10% to 15% less than you will for the cost of a detached garage.

      If you want to run electricity and plumbing to your garage, it often works out more cost-effective to run the pipes and wiring to an attached structure.

      Demolition Costs

      When you’re replacing an old garage, you need to factor in the costs to demolish the existing structure. These typically run from $4 to $8 per square foot for detached structures or $5 to $15 per square foot for attached structures.

      Architect Fees

      You may also have architect fees to factor in as well. Architects typically charge between $125 to $250 per hour or $2 to $15 per square foot. It isn’t unusual for architect fees to run over $2,000.

      Garage Plan Prices

      If you don’t need an architecturally designed garage, it’s possible to purchase premade garage plans that cost between $500 and $1,000.


      You will need a permit to build your garage. The cost for a garage building permit varies depending on your location. Budget $1,200 to $1,500 for this. A general contractor can often support you through the application process.

      Cost to Build a Garage Yourself

      You could build a basic detached garage for between $5,000 to $25,000 if you only pay for the materials. Contractor rates tend to eat up at least 50% of your total budget.

      DIY vs. Hiring a Pro

      Even though you can make considerable savings by building a garage yourself, this is a complex, time-consuming project and not one to tackle unless you have solid building experience. Mistakes could prove costly and unsafe.

      Taking on certain parts of the build yourself may be a better option to help save costs rather than DIYing the project in its entirety. Making a mistake while drywalling or painting won’t have the serious consequences that an error when laying the foundation or putting up roof trussing can have.

      General contractors provide peace of mind, have insurance, and are familiar with local building codes and regulations.


      Is it possible to build an apartment above the garage?

      Building an apartment above a garage is possible, but the planning process, permit applications, and budgets will be considerably different. The cost to add an apartment typically ranges from $110 to $250 per square foot. It will be more expensive if the garage is detached and will depend on the finish you’re looking for.

      How much value does a single, double or triple car garage add to your home?

      Typically, you will get about 75% to 85% of your investment back when you sell your home. On average, a garage adds between $12,750 to $33,150 of value to your home.

      What are some ways I can save money on my garage build?

      On a limited budget building to size, forgoing windows, and eliminating upgrades like electricity, HVAC and plumbing can all shave money off your total build costs.

      Prefabricated garage kits are one of the most economical options, and conducting some of the basic finishing work yourself can be worthwhile.
