How Much Does It Cost to Build an RV Garage? [2026 Data]

The cost of an RV garage typically ranges between $36,000 and $140,000, though most homeowners spend about $90,000 on the project. On the low end, an RV garage can cost just $9,000, while large garages with lots of add-ons can run upwards of $180,000. When you’re not out on the road discovering all the great outdoors has to offer, you’ll want to park your RV somewhere safe and secure. An RV garage offers security, shelter from the elements, and an easier way to maintain and access your vehicle for your next adventure. Here’s everything you need to know about how much it costs to build an RV garage.

RV Garage Cost by Size

Most RV garages come in the same general size, roughly 14 feet by 50 feet or 700 square feet. Depending on the type of garage you choose, its design, and the materials used in its construction, you can expect to pay anywhere from $40 to $140 per square foot. To get a more precise quote that’s tailored to your property, the RV’s dimensions, and your personal design preferences, contact a garage builder near you for a written estimate.

Keep in mind that you should plan on sizing up your garage if you also want it to serve as a place to store your primary vehicle or a place for storage.

RV Garage Cost by Siding Material

The siding material you choose for your RV garage will greatly impact the final price. Vinyl is the most affordable option at $3 to $12 per square foot. The table below estimates what you’ll pay for siding on a 700-square-foot RV garage.

Garage Builder Costs

Labor costs to build your RV garage will average from $20 to $75 per square foot, representing an average of about 50% of the total project cost. Garage builders don’t typically charge by the hour, so you’ll want to get competitive quotes from at least three contractors before you make a final decision. The quotes will also help you finalize a more accurate budget for your project.

Additional Costs to Consider

In addition to the main cost factors, there are other expenses that can push up the price of your RV garage if you’re not keeping a close eye on your budget.

Garage Door

RV garage doors cost anywhere from $1,300 to $7,000, depending on the size, as most RV garages will need oversized doors to fit the larger vehicle. The type of material you choose for your garage door can greatly affect the price, with aluminum doors coming in toward the low end of the price range and fiberglass or wood composite doors coming in toward the high end of the price range.

Garage door openers are another expensive to consider and can cost around $450 each. Even if you’re DIYing your RV garage build, we recommend hiring a professional for this step, as garage door openers may not work properly if installed by an inexperienced DIYer.

Air Conditioning

Adding HVAC vents and ducts to an RV garage will cost between $475 and $2,100 if your garage is attached and can connect to an existing HVAC system. If you’re building a detached RV garage, expect to pay to install a standalone HVAC system. A common option is a ductless mini split, which totals around $4,000.

Water

Adding plumbing to your RV garage will cost anywhere from $375 to $1,900. Again, this price estimate depends largely on whether you can connect the structure into existing water lines or if you need to have new water lines installed entirely. 

Electricity

Running electrical lines to your RV garage costs around $125 to $300 if you’re installing an attached RV garage with easy access to existing electrical wiring. If you’re building a detached RV garage, the cost to run electricity to your structure typically falls between $1,000 and $2,500. You can add on an additional $75 to $150 for each switch, outlet, and light fixture you need to install.

Insulation 

The cost to insulate a garage is between $0.50 and $1.25 per square foot. Since the average RV garage is 700 square feet, you’ll pay anywhere from $350 to $875 to insulate your RV garage on average. If you want to install an insulated garage door on top of this, you could pay an additional $4,000.

Attached vs. Detached RV Garages

RV garage kits generally come in two distinct types: attached and detached. Which one you should choose depends on the space you have available, your budget, and your personal preferences. 

An RV garage that’s built off to one side of your home and is attached to the home’s structure is less expensive than one that’s detached. However, you’ll spend more for things like insulation in an attached garage, which you won’t need in a detached garage.

Most homeowners select a detached garage style to protect their RVs. This style is more flexible because you can put it anywhere on your property where it’ll physically fit, with allowances for driving and maneuvering the RV itself. Detached garages cost less in some cases because they also give you more flexibility in choosing materials, which can help you save money overall. 

Site Conditions and Location

The condition of the site you’ve chosen for your RV garage will have a direct impact on your total project costs. If your site needs to be graded to a level surface, or if it needs work to provide good drainage, your costs will increase, as will the total project time. The same is true if you plan to run power or water to the garage but the location is removed from your home’s plumbing and electrical systems.

Permits

Most municipalities will require you or your general contractor to acquire a building permit before constructing or installing your garage. The cost for a permit for an RV garage averages between $1,200 to $1,500, although your town or city may charge more or less.

Why You Should Hire an RV Garage Building Pro

While it’s possible to build your own RV garage (especially with a fabricated kit), we always recommend working with a local garage contractor on this project. Even if you opt for a prefab kit, these pros will complete the project much faster, all while ensuring the structure is sound and stable for years. And if you want to build something custom, these experts will help bring your vision to life. Though they charge $20 to $75 per square foot, the benefits of pro garage builders make the costs more than worth it.

Here’s why it’s ideal to hire an RV garage building pro

There are a few reasons you should consider working with a pro to build an RV garage, such as:

• Ensuring the structure is safe and sturdy

• Ensuring code compliance

• Avoiding injury caused by moving heavy building materials

• Access to work warranties and guarantees

• Help securing permits, if needed

• Help creating a custom garage to fit your needs and preferences

If you want to DIY an RV garage build

While we don’t recommend taking this entire project on by yourself, there are still a few ways to save by handling the prep yourself:

• Come up with a list of needs for your RV garage to ensure an accurate quote

• If using a prefab kit, order it yourself and get professional help with assembly

• Clear the area where the garage will be built

• Make sure you know how much space your garage will need to fit your RV, and don’t forget to add some extra space for clearance and storage

How You Can Save Money on an RV Garage

Installing an RV garage can be a significant investment. To save money on the project, consider the following tips:

• Comparison shop for different methods of building your RV garage: Even if you’re leaning towards a DIY experience with a garage kit, check out how much it would cost to have one built based on available plans versus hiring a specialist to design and assemble one for you. 

• Get at least three quotes or prices from contractors: This is the most effective way to evaluate your options and make sure you’re getting the best possible price.

• Explore different materials: You may be able to save some money by choosing a different material for your garage.

• Keep it simple: It’s tempting to shoot for the moon and install plumbing, HVAC, and full electrical work, but these will all drastically increase your installation costs.

• DIY what you can: While it’s best to hire a professional for major construction, you can save money by DIYing simpler projects, like installing garage organization solutions, finishing interior walls, and installing light fixtures.

Does an RV Garage Increase a Home’s Value?

An RV garage can increase your home’s value thanks to the additional storage space it offers. On average, homeowners can see a 65% return on investment (ROI) on a new RV garage. Although the ROI isn’t quite as high as adding a traditional garage, you could see a higher return if you add a workspace to the RV garage or convert part of it to a living space.
