There is no easy answer to how much a garage will cost to build. There are lots of variables and things to consider before the project can even start. A significant investment like a garage is essential to calculate all the potential costs and expenses.

There are variables like:

Attached or Detached Garage
Garage Size Factors
Garage Prefab Kits vs. Prebuilt vs. Custom Design
Garage Foundation
Garage Driveway
Garage Framing
Garage Walls/Siding
Garage Roof
Garage Door
Garage Person Door
Garage Windows
Garage Flooring
Garage Insulation
Electric, Plumbing, and HVAC
Electric Door Opener
Drywall and Trim
The Cost of Permits
Total Garage Cost

Let’s dive in and see also what is the cheapest way to build a garage.

Attached or Detached Garage Cost

First, you have to decide whether you will attach the garage to your house or build a detached garage on your property. Both have pros and cons.

The attached garages are usually built at the same time as the house. Adding one later can be costly. The attached garages are convenient for cold areas, and you have direct access from the house.

Downsides can be car fumes, and other unpleasant smells could drift into the house. They also need to match the design of your home. Sometimes they are the only option because of the lot size.

Detached garages can be almost anywhere on your property and easily customized and constructed anytime after the initial house construction. They keep the loud noises and smells away from the house. It is easy to add a second story of loft too in a detached garage for extra space.

Downsides are exposure to weather if you don’t build a breezeway.

I wrote an article about different types of garages. Check it out here for information about all kinds of garages.

There is no single answer to which type of garage will cost less to build. There are lots of factors that affect the price drastically.

Most of the infrastructure is already nearby with attached garages, but making significant changes to the house’s structural integrity will bump the costs.

You may have to pay for electricity and plumbing carried out to the garage with detached garages if you need power and water in the detached garage.

A detached garage with a breezeway to the house is a good option if the property has room for them.

The average cost for a one-car attached garage is between $7,500 and $12,500, 2-car garages start at $14,100, and 4-car garages go up to $42,700. The average cost for a detached garage starts at $14,250 with the average homeowner spending $19,600 to $28,200. (Source homeguide.com)

Size	Attached	Detached
1 Car	$10,800	$13,200

Detached Garage

A detached garage costs $25,000 to $55,000 or about 20% to 40% more than an attached garage. Some homeowners have reported costs up to $120,000. Detached prices tend to run higher. (source homeadvisor.com)

Attached Garage

An attached garage costs $15,000 to $40,000. Some reports have them as high as $100,000. A two-story attached garage to extend living space can cost as much as $180,000. (source homeadvisor.com)

Garage Size Factors

Garage size is maybe the most crucial factor when deciding what you need, your budget, and the garage project’s total cost. Choosing the garage size is more than just thinking about how many vehicles you own.

When considering the garage’s size, you need to ask yourself what you are using it for. Like how many cars you or your family members own or will own in the future—the size of the cars. Also, if you need some storage space besides the vehicles. Things like workbench and cabinets. Maybe you have a Lawnmower. Or perhaps you need additional living space or a gym.

I wrote an extensive article about garage sizes. Check it out here. To help you decide the optimal garage size for you.

On average, the cost to build a garage is about $35 to $60 per square foot depending on the dimensions, finishing, and if it’s attached or detached. The cost to build a 1-car garage is between $7,500 to $14,200. The most common 2-car garage dimensions fall in the 400–576 SF range which costs between $19,600 and $28,200, while a 3-car garage will measure 576 to 864 SF and cost about $28,200 to $42,300. Average Range is $19,600 to $28,200. (Source homeguide.com)

Garage Prefab Kits vs. Prebuilt vs. Custom Design

Prefabricated or prebuilt garage sections can be transported to the construction site and assembled in just a couple of days. Customers generally choose a base design that can be customized somewhat or, in some cases, many ways. This makes the whole garage building process fast and easy to accomplish.

The terms “prebuilt,” “modular,” and “prefabricated” are often used interchangeably.

Garage Prefab Kits

With garage prefab kits, all the design, sourcing, measuring, and cutting of the materials to the correct size is already done. The parts interlink easily with each other. You only have to put everything together.

Garage kits are prefab garages that you can build and set up as DIY hands-on projects. They are easy to build even with limited experience. They are also cost-effective, and you only pay for the materials if you DIY. There is limited customization or not at all. Kits are usually basic models and come with a simple coating.

Prebuilt Garages

Prebuilt modular garages are often more expensive than garage kits. These can refer to finished buildings or prebuilt modules like individual walls. The modules (two or more pieces) get assembled on site. With a prebuilt garage, you also pay for the high-quality materials, customization, and labor cost.

Prebuilt garages can be built on-site or transferred as prebuilt on your property. They offer many customization options like style, features, and size. They cost more than prefab garages, but you get high-quality materials and labor costs included. Prebuilt garages are aesthetically pleasing and look good on property.

Custom Design

With custom garages, you pay for planning and design from a professional architect. There is also the cost of materials, labor, and equipment. These take a long time to build. But you really get something unique.

Custom garages are usually built from scratch and designed by professionals with all the customer wanted options. These garages can have it all or just the pieces you need. So you really get what you want. All the customization is available, and only your imagination and bank account are the limits.

Garage Foundation Cost

Ground preparation is essential for any garage. The foundation selection includes garage size and height and possible frost lines in the area.

Your options include a gravel pad and a concrete foundation.

Gravel Pad is cost-effective and usually done with gravel surrounded by a treated wood perimeter. They are a good choice for carports, small prefab kits, or small modular garages.
Concrete Foundation is a must choice for larger garages and proper support. There are 4 different kinds of options for concrete foundations:
Floating pad – Simple and cheap. Usually 4” of concrete over 5” of clean stone.
Floating foundation – 4” floor with moisture barrier under the concrete and mesh reinforcement and footers up to 12” deep around the perimeter.
Monolithic foundation – Similar to the floating foundation with the addition of a frost wall about three feet under the pad and 10″ wide around the pad.
Block foundation – at least 2 “wide footers are poured at the required frost depth around the perimeter. Concrete blocks are built on top of the footer. The foundation is completed with a 4” concrete floor.

Build the foundation right to avoid any problems in the long run. You don’t want a ruined garage because of a poorly made foundation.

A garage foundation costs between $2,000 and $7,000 depending on the size. A standard 16’ x 24’ (1-car) garage foundation costs $2,500, a 24’ x 24’ (2-car) costs about $3,500, and a 36’ x 24’ (3-car) garage foundation runs $5,500 on average. (source homeguide.com)

A garage foundation costs $1,500 to $8,500. You’ll spend more depending on the size of the structure. For a two-car unit, or around 600 square feet, expect to pay $3,000 to $7,000. (source homeadvisor.com)

Size (4” Deep)	Square Feet	Average Cost
16’ x 24’ (1 car)	384	$2,039 – $3,191
20’ x 20’ (2 cars)	400	$2,124 – $3,324
24’ x 24’ (2-3 cars)	576	$3,059 – $4,787
20’ x 30’ (2-3 cars)	600	$3,186 – $4,986
36’ x 24’ (3-4 cars)	864	$4,587 – $7,179

Garage Driveway Cost

The driveway is an integral part of the garage. Ideally, you’ll be able to place the garage in such a way that you can maximize the space in front of the garage for turning the car if needed. Your options include gravel, asphalt, concrete, and high-end driveways.

Gravel needs to be reapplied from time to time if it washes away with heavy rain or snow.
Asphalt driveway will last around 15-20+ years and requires little to no maintenance.
Concrete is the most durable option and can be customized with colors and different finishes.
High-end driveways are made of bricks, cobblestone, or pavers and look nice and elegant. There are also options to heat the driveway for wintertime or permeable driveways for heavy rainfall areas.

A concrete driveway costs between $2,900–$5,500 depending on the length and width of the driveway and whether you use concrete or asphalt. (source homeguide.com)

Asphalt paving costs $3,000-$6,500. (about $2.50 to $4.50/sq. ft)
Sealing asphalt costs $250-$700.
Concrete driveway installation costs $1,800-$6,000. (about $4.50-$15/ sq. ft)
Coating concrete costs $1,500-$3,000.
Driveway pavers cost $6,100-$30,400.
Gravel driveways cost $1,500-$6,000. (about $1.25-$3.75/sq.ft)
Driveway chip sealing costs $650-$3,000.
(source homeadvisor.com)

Garage Framing Cost

2×4 are standard options when building the garage framing, but for large or insulated garages, it is better to use a 2×6 frame. Make sure to use good quality wood like timber.

Garage framing costs $10 to $35 per square foot, depending on which option you select.

Timber $10 per square foot
Concrete Block Frame $10-$35 per square foot

Framing costs $1-$5 per square foot. You’ll spend another $4-$8 per square foot in labor depending on your location and the complexity of the build. (source homeadvisor.com)

Garage Walls/Siding Cost

You have a lot of options for garage walls/siding to choose from. It’s best to match the garage with other buildings on the property and factor in budget, maintenance, and durability. Your options include wood, vinyl, metal, bricks, or stucco.

Wood – has many styles to choose from and looks great but requires regular maintenance.
Vinyl – is very durable and low maintenance and has lots of color and style choices.
Metal – can withstand almost anything depending on the quality—durable and low maintenance.
Bricks/Concrete Blocks: Are energy-efficient and have long-lasting durability.
Stucco – Decorative coating for walls.

Siding Material	Cost Per Square Foot
Vinyl Siding	$0.70–$3
Aluminum Siding	$4–$7
Brick Siding	$11–$15
Engineered Wood Siding	$3–$8
Fiber Cement Siding	$6–$10
Stone Siding	$11–$15 ($18 for real stone)
Wood Siding	$3–$10

Garage Roof Cost

Framing the roof is usually made by trusses and will affect the cost depending on the garage you are building. Maybe you have an attic area, or if you are building an entire second floor, you need a floor joist. It’s a good idea to have at least a 12″ overhang on all sides to keep rain further away from the sides of the garage. Trusses and supports cost about $4.90/SF

Roofing costs anywhere from $1,000-$10,000, depending on its size. Expect to spend an added $600-$6,000 in labor. (source homeadvisor.com)

Ceiling material options include cork, wood (veneer), drywall, gypsum, plastic tile, or Styrofoam tiles at the cost of $1.80 to $10/SF

Roof Options include :

Asphalt Shingles – Durable and easy to install. A popular choice for sloped roofing. Common and good-looking style is dimensional shingle. The price is about $3.60/SF
Corrugated Metal – Easy to install and looks good. Very durable too.
Standing Seam Metal – Style where the fasteners are hidden. Has the maximum durability of any metal roof. Looks nice.
Wood Shakes – Looks good with many styles.
Slate / Synthetic Slate – Super long-lasting but expensive.

Roof Styles include – prefabricated or prebuilt garages.

Regular Roof Style
Boxed Eave Style
Vertical Roof Style

Garage Door Cost

Again you have many options and styles to choose from. You also need to consider insulation and if you will have an electric door opener. Most people opt for sectional, roll up or swing outdoors. Materials include steel, aluminum, wood, vinyl, glass, and composite.

You need also consider door configuration depending on the size of the garage.

I wrote articles about different types of garage doors here and garage door openers here. Check them out to help you decide the door style for you.

Garage door installation costs $750 to $1,500 on average for each door. Since most have two, expect to pay $1,500 to $3,000 total. For oversized doors, such as in an RV stall which is larger and less common, add another 50%. Custom doors can set you back up to $10,000 each (source homeadvisor.com)

Garage door prices are $400 to $1,200 on average, depending on the size, style, material, design options, and customizations. Aluminum doors are the least expensive, but they are also more likely to exhibit dents and physical damage than the next cheapest option of a steel door. Fiberglass and wood doors generally offer a more diverse range of designs. (source homeguide.com)

Garage door installation costs $550 to $1,800, with most homeowners spending between $1,000, depending on the style, size, and quality you choose. Installing a single-car garage door could cost as little as $550. This price includes the doors, labor, tracks, and materials. (source homeguide.com)

Garage Person Door Cost

The garage side door has many benefits like convenience, privacy, safety, energy conservation, and save time. In a detached garage, this is almost a must option to include in the plans. These cost about $100 each or up to $2,500 for high-end security options.

Check the article about garage side doors benefits here.

Garage Windows Cost

Opting for windows lets in the natural light beside electric lights. If you spend a lot of time in the garage in any activity like car repairs or workshop, you will want to add some windows. There are a lot of window dimensions to choose from and styles for any garage. Windows also comes as insulated and non-insulated choices.

The average cost to add windows to a garage is $100 to $600 per window.

Windows cost $100-$1,300 or more depending on the materials, size, and style. You’ll pay another $100-$300 per window for installation. (source homeadvisor.com)

Garage Flooring Cost

A concrete foundation will act as a floor fine by itself. Especially when sealed with concrete sealant when possible. Other options include:

Epoxy
Paint
Tiles
Mats
Stains & dyes
Sealed concrete

Check out the article here about the benefits of epoxy floors in the garage.

More info about tiles here and sealing the concrete here or perhaps putting down some mats.

Garage epoxy floors cost $1,500 to $3,000. Garage floor refinishing and polishing costs $3 to $10 per square foot for concrete resurfacing. You can also use other flooring types costing $1,500 to $4,500, like tile. (source homeadvisor.com)

Garage Insulation Cost

Garage insulation is an excellent idea in very cold or warm regions if you plan to heat or cool your garage. Adding insulation will save you a considerable amount of money in energy bills. An insulated garage offers year-round comfort as it moderates the temperature. Insulation also adds soundproofing.

There is a whole article here about the benefits of insulation. Check it out.

Insulation Type	Average Cost Per SF	1 Car 12’x24’	2 Car 24’x24’
Batt	$0.93	$268	$536
Blown In	$1.50	$432	$864
Spray Foam	$0.50	$144	$288

Electric, Plumbing and HVAC Cost

Electricity is kind of a must for lights and garage door openers, at least. It is good to add enough capacity to the plans if you plan a serious workshop in the garage.
Plumbing is needed if you use water in the garage.
HVAC (Heating, ventilation, and air conditioning) are needed for year-round and heavy usage of the garage.

Read more about garage heaters here and garage cooling here for more info and help you decide.

Here is also guides for best garage heaters and coolers.

Electrical and lighting work can add about $1,000 to $2,500 to your garage build. You’ll need electrical outlets if you plan on using power tools in the garage space—a 100-amp subpanel and between 10–12 outlets in the garage. Along with this, either adding traditional bulb fixtures or ceiling–mounted, cost-effective LED workshop lights (at around $80 each) will be enough for the most demanding garage requirements. Four to 6 sockets with a 60-amp subpanel may work if you are just going to park your car and not work in there. If you are planning on having your clothes dryer or some other appliance that needs a 240v outlet, you can expect to pay an additional $220 to wire for that. (source homeguide.com)

Heating and Cooling Your Garage -You can add an all-in-one heating and cooling unit for between $700 and $1,500, depending on the size of the space and the temperature you need to address inside your garage. (source homeguide.com)

Running Water – Depending on how far the garage is from the water supply, what kind of fixtures you want, and whether you just want a functioning sink, drain, or a sink and a shower, a plumber should be able to tap into your water supply and connect a faucet and handbasin and/or a shower for $1,100 to $3,000. (source homeguide.com)

Plumbing installation costs $600 to $1,600 per fixture.
Electrical installation costs for a detached garage run $1,200 to $2,500.
HVAC costs vary depending on what you want to install

Electric Door Opener Cost

You also need to add the cost of the door opener if you install an electric door opener. For heavy garage usage, it is recommended to have one. If garage usage is rare, you can opt for a manual door. The garage door springs will make even a heavier door easy to operate by hand.

Again there are opener options like chain drive, belt drive, screw drive, direct drive, and jackshaft drive.

I wrote articles about different types of garage doors here and garage door openers here. Check them out to help you decide the right type of garage door opener for you.

The average cost to install a garage door opener ranges from $127 to $199, while the garage door opener itself costs around $120 to $288. This brings us to a total cost of between $247 and $487 to install your garage door opener. Prices vary depending on the brand, model, power, and type of garage door you have. (source homeguide.com)

Prices for garage door openers vary depending on the brand, model, power, and type of garage door you have, but installation prices start at $127 with an average price of $199 in most states. Basic installations do not usually include removal of an old unit, so be sure you ask your pro what’s included in the install. Installation prices are similar at many home improvement stores.

Drywall and Trim Cost

Many garages are left unfinished, with the walls left open so the studs can be seen. Finishing the garage with drywall and paint will make the place look nicer. Keep in mind if you plan to install insulation, the time to do so is before the drywall. Finishing the interior cost varies greatly depending on what you are planning to do with the space.

Several wall systems do not require any drywall and can be installed directly to the studs. Most building codes dictate though you have to have drywall installed before installing garage wall panels.

Check garage wall systems out in this article.

Drywall costs $1-$3 per square foot of wall space or about $8-$12 per 4 foot by 8-foot panel just for the materials. The attached units require fire-rated drywall at least on the wall or ceiling shared with living spaces. Other walls covering ideas include wood sheathing, metal panels, plastic or vinyl paneling, and cement board. (source homeadvisor.com)

There is a wide range of wall options to suit all design considerations that will cost $1.80 to $30 per square foot,

The Cost of Permits

Building permits typically cost $100-$200, but this varies greatly from state or county to the next. With a permit, you get peace of mind, and you keep on the right side of the law. The permit will affect the insurance claims, too, in case of an accident.

When the garage is finished, a representative from your local government building department will come to check that the garage meets all the required building codes. If the garage passes the inspection, you know your garage is deemed to be safe and well-built.

Total Garage Cost

Everything adds up, and the total cost of your garage project will vary wildly depending on all the variables discussed in this article. You have to add everything up and estimate the price range of the whole project from start to finish.

Building a garage costs $17,000 to $38,000 on average. A typical build runs $40 to $70 per square foot. Large, luxury custom work with high-end materials like slate and brick costs $50,000 to $100,000. Adding a workshop or extra stalls could add another $10,000 to $40,000 (source homeadvisor.com)

Building a garage averages $50 per square foot. Homeowners report paying between $16,748 and $38,918. A single-car unit ranges from $10,500 to $27,000, 2-car between $14,500 and $40,300, and a 3-car or more at $57,000+ (source homeadvisor.com)

The average cost to build a garage is $35 to $60 per square foot. The cost to build a 1-car garage is between $7,500 to $14,200, a 2-car garage costs $19,600 and $28,200, and a 3-car garage ranges from $28,200 to $42,700. Depending on many factors, homeowners can expect to see about an 80% return on their investment in relation to home value. (source homeguide.com)

Garage Plan Prices

Premade garage plans cost $500 to $1,000. You can spend up to $2,000 (or more) to hire a draftsperson or architect to change existing documents or create custom blueprints. (source homeadvisor.com)

Garage Construction Cost

Labor rates for construction cost about 50% to 70% of the finished building or around $20 to $49 per square foot. However, if you choose expensive materials, like hardwood siding and spray foam insulation, you’ll end up paying more for materials than labor. (source homeadvisor.com)

Cheapest Way to Build a Garage (Your Options and Tips)

Detached garages: Single-car designs are available completely prebuilt and transported to your site. All the design and possible customization are done beforehand, so on-site time is minimal. With a simple gravel pad, this could be the cheapest way to have a garage.

Attached Garages – When doing major renovations in the old house. Adding a garage could be easiest before moving in. It’s a massive project to add an attached garage in most cases. The project becomes much more manageable if building a short-covered breezeway between the garage and the house.

What Is the Cheapest Type of Garage to Build?

Prefab kit or prebuilt garage without a floor with a simple gravel pad. Pre prefab garages are cheap because you don’t have to pay for labor, design, or construction.

The cheapest garage to build is a single stall steel kit for $3,000 to $5,000.

Prefab kit garages do not come with a foundation, so you have to build one. A concrete slab is recommended, and footing for the garage to hold it in place.

Another option is pole barn or sometimes referred to as post-frame construction. They are pole-style buildings typically without foundation. The posts are sunk deep into the ground.

Laminated wood posts are used to frame the garage, form a structure, and support the load from winds or snow. Metal panels hold the whole design together. This type of building offers lots of wide-open storage space without interior load-bearing walls.

Pole Barn Sizes & Prices

Size	Square Feet	Average Cost	Typical Use
16×16	256	$4,000 – $8,000	1 car garage
20×20	400	$4,500 – $12,000	1 or 2-car garage,
20×30	600	$5,000 – $15,000	1 or 2-car garage
24×24	576	$5,000 – $15,000	1 or 2-car garage
30×30	900	$7,000 – $20,000	3-car garage
30×40	1200	$10,000 – $25,000	3-car garage
30×50	1500	$12,000 – $30,000	4-car garage

Portable and pop up garages cost $130 to $5,000. They’re generally PVC or metal framed with a soft cover, such as vinyl. They come in sizes ranging from a single-car to double-wide or deep. They have limited weight-bearing capacity and don’t always hold up well to strong winds. (source homeadvisor.com)

You could also opt for a covered or portable carport. Read more about carports here.

Metal garages cost $3,000 to $11,000 for a DIY kit, with labor doubling that. Custom metal structures might run as much as $40,000 for a large building. Not only are they cost-effective, but they are also built much quicker than wood or concrete. However, they often don’t fit with the aesthetic of many neighborhoods and are often prohibited by HOAs. (source homeadvisor.com)

Garage kits cost anywhere from $2,000 to $30,000. They include all the pieces required to build the unit with no waste. They sometimes have portions of the building already built, like roof trusses, but that’s not always true. They include the roof, framing, hardware, panels, and siding. They don’t include the labor, foundation, or utilities. (source homeadvisor.com)

Is It Cheaper To Build a Garage or Buy a Kit?

You have three choices, actually. Prefab garage kit, Pre-built, and custom design.

With custom garages, you pay for planning and design from a professional architect. There is also the cost of materials, labor, and equipment.

So buying a kit would be a cheaper choice than building a garage from scratch. Pole barns can be cheap choice too.

Prefabricated garages cost $10,000 to $50,000 for most standard single and double-wide buildings. That price includes the unit, foundation, delivery, and installation. The unit alone costs $5,000 to $40,000. Two-story and luxury prefabricated garage kits can hit $95,000 or more. (source homeadvisor.com)
