Building an RV garage comes with an average price tag of about $90,000, or roughly $40 to $140 per square foot. However, it can range from as low as $9,000 to as high as $180,000 depending on the design and local labor rates. Picking the right location, sizing the space for your rig, and choosing quality materials all influence what you’ll pay. Hire a licensed garage builder near you to make sure the structure meets code, wraps up on schedule, and fits your RV like a glove.
Cost Factors for Building an RV Garage
Location, square footage, materials, and labor drive your final price.
Location
Begin by selecting the ideal location for the garage. You’ll need good drainage, straightforward access to plumbing and electrical lines, and an exterior style that blends with your home.
Where you place the garage dictates its size, materials, and the number of doors or windows you’ll need. If the site sits far from the house, plan on higher costs to run power and plumbing. Check local bylaws and building codes as well—they may limit the garage’s height or footprint.
Size
Your RV’s length and width drive garage size—bigger rigs need bigger buildings. Expect to pay between $40 and $140 per square foot, depending on the design and materials used. A typical RV garage measures about 20 feet wide, 50 feet long, and 14 feet high.
Some homeowners opt to add extra space in the RV garage for additional features or storage. Keep in mind that some municipalities have codes that require RV garages to be a specific size; therefore, refer to your local building department for the relevant regulations.
| Square Feet | Average Cost Range |
|---|---|
| 700 | $28,000–$98,000 |
| 800 | $32,000–$112,000 |
| 850 | $34,000–$119,000 |
| 900 | $36,000–$126,000 |
Garage Type
Whether the structure is attached to your home or stands alone is one of the biggest cost drivers for any garage, including one built for an RV.
Attached RV Garage
An attached RV garage shares at least one wall with your home. Because RVs are tall, the structure has to be, too. Attached builds are less expensive than detached ones, but you’ll likely spend more on insulation to maintain steady indoor temperatures.
Materials
Material choice is a significant price factor, no matter whether the garage is attached or detached. Just like a home build, everything from the foundation to the siding affects the bottom line.
The most common siding materials are vinyl, wood, brick, and metal. Vinyl siding is the most standard, ranging from $3 to $12 per square foot, while brick can run up to $20 per square foot. In addition to the main structure, you will also need to budget for other materials, including:
Roofing material prices range from $5,000 to $10,000
Garage door prices cost $1,300 to $7,000, depending on the size
Garage door opener installation costs an average of $450 each.
Window installation costs anywhere from $3,445 to $11,835
Insulation costs between $0.50 and $1.25 per square foot, $350 to $875 for a standard 700-square-foot garage. If you want to install an insulated garage door on top of this, you could pay an additional $4,000.
Labor
Labor to build an RV garage runs $20 to $75 per square foot—about half of the total project cost. Share your RV’s dimensions and must-have features with at least three local garage builders and ask each one for a written quote so you can compare apples to apples.
Hiring a local garage builder can be more cost-effective than hiring each specialist individually. Professional contractors can handle every aspect of the build, including hiring subcontractors to work on key components such as plumbing, siding, HVAC, and electrical work.
Permits
You will likely need to apply for and obtain a permit to build an RV garage. Building permits cost $1,200 to $1,500, depending on your location. Check with your local government or ask your general contractor to get the required building permits on your behalf.
Does Building an RV Garage Increase Home Value?
Adding an RV garage is often a wise investment, especially in areas where RV ownership is prevalent. The expected return on investment (ROI) varies, but many homeowners can recoup about 60% of their initial cost when selling their property.
The actual increase in home value depends on factors like the quality of construction, local real estate market conditions, and the garage design. Potential buyers often view a well-constructed RV garage as a premium feature, making it a significant selling point. While building an open-air carport may be less expensive, a fully enclosed RV garage offers better protection for your recreational vehicle from the elements. It provides greater security and can allow for more storage options.
Budgeting for Building an RV Garage
Planning ahead keeps costs in check and ensures the finished garage truly works for you and your RV.
Request detailed quotes from multiple contractors to compare pricing.
Consider a simpler design with minimal architectural complexities to reduce labor and material costs.
Opt for pre-engineered metal building kits, which can be more cost-effective than traditional construction methods.
When selecting materials and components, factor in long-term maintenance, like future garage door repair costs.
Install water, electric, and sewer hookups for your RV during the construction phase.

Frequently Asked Questions
When building an RV garage, you’ll need to aim for enough clearance to move comfortably around the rig. While most RVs are roughly eight feet wide, give yourself a few extra feet on each side for safe maneuvering. A 14-foot interior height, a 12-foot-plus door width, and lengths of 40 to 45 feet cover most models. If the lot allows, consider sizing up to accommodate storage shelves or a small workshop in the future.
An RV garage requires a door that exceeds the height of your vehicle’s highest rooftop feature. You must select a door that stands 12 to 14 feet tall, ensuring it provides full clearance for air conditioning units, antennas, and satellite systems. This door height guarantees that your RV moves in and out without any risk of contact or damage, protecting both the vehicle and the structure.
Plan on six to 10 weeks for a typical detached RV garage and 12 to 24 weeks for an attached multi-car version. Your exact timeline hinges on design complexity, permit approvals, material lead times, and the builder’s schedule. Ask your contractor for a detailed calendar up front so you know when to expect each milestone—from the foundation pour to the final inspection.
