An RV garage costs $90,000 on average, but it can cost between $36,000 and $140,000, depending on size and material type.
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.
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.
| RV Garage Size (Square Feet) | Cost |
|---|---|
| 700 | $28,000–$98,000 |
| 800 | $32,000 –$112,000 |
| 850 | $34,000–$119,000 |
| 900 | $36,000–$126,000 |
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.
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.
| Siding Material | Cost for Siding Material Alone |
|---|---|
| Vinyl | $2,100–$8,400 |
| Wood | $700–$10,500 |
| Brick | $7,000–$14,000 |
| Metal | $2,100–$11,200 |
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
The easiest and most low-cost way to DIY your new RV garage is to purchase a prefabricated garage kit, which costs an average of $15 to $25 per square foot. When you build a garage yourself, you can save a little less than half of the total project costs, as you’ll be saving $20 to $75 per square foot in labor costs.
However, even if you choose the simplest DIY garage kit, you'll still need several tools and materials to finish the job. You'll also need assistance maneuvering the parts into place and securing them to each other and the ground.
For most homeowners, it's better to hire a local garage contractor. Building any structure is complicated and dangerous, and it's worth paying a pro to ensure the job is done properly and in accordance with local building codes.
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.
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.

Make sure you’re getting the right size to meet your space needs, including enough space both side to side and vertically to accommodate your RV’s features and allow you to safely move it in and out of the garage.
If you’re building an attached and enclosed garage for your RV, you’ll also want to give some thought to whether you’d like to add workspace, water or electricity, or additional storage. If so, you’ll need a garage with larger dimensions.
On average, RV garage doors are 12 to 14 feet tall to accommodate the large vehicles. Most RVs are approximately 9.5 feet tall but can be taller due to features such as air conditioners, satellite dishes, and luggage racks
The time it takes to build a garage depends on the type and size of the garage you choose. On average, most garage builds take between six and 10 weeks to complete, though an attached multi-car garage can take between 12 and 24 weeks.
