A 50×100 RV garage gives you a lot of room to work with. At 5,000 square feet, it can hold a large RV, other vehicles, tools, equipment, and a good-sized workshop without feeling cramped.
But the size alone doesn’t make a good RV garage. Door height, door placement, turning room, storage, and the way you divide the floor space all matter. A little planning before construction can save you from expensive changes later.
This guide covers the main things to think about when planning a 50×100 RV garage, including RV door height, practical layouts, construction costs, and common design choices.
How Big Is a 50×100 RV Garage?
A 50×100 building has:
- 50 feet of width
- 100 feet of length
- 5,000 square feet of floor space
That’s enough space for much more than an RV parking bay.
For example, you could use part of the building for RV storage, another area for cars or trucks, and the remaining space for a workshop or equipment storage. You could also keep most of the building open and use one side for cabinets, shelving, and a workbench.
The key is deciding how you expect to use the building five or ten years from now. A garage designed only around your current RV may feel limiting if you later buy another vehicle, add equipment, or want a larger workshop.
Before settling on the footprint, comparing different pole barn layouts can help you see how different uses can fit into a large open building.
Choosing the Right RV Garage Door Height
The garage door is one of the first things to plan because you can’t easily change a building’s structure around it later.
A typical RV can be much taller than a regular pickup truck or car. Depending on the RV, roof equipment, air conditioners, satellite dishes, and other accessories can add to its overall height.
That’s why you shouldn’t choose the door based only on the RV’s published height.
Measure the RV and everything on top
Before choosing a door, measure the RV from the ground to its highest fixed point. Include roof-mounted equipment that will stay on the vehicle.
Then consider how much clearance you want above it.
A door that’s technically tall enough may still be inconvenient if there’s only a small amount of clearance. You also need to account for the garage door itself, framing, tracks, and the structure above the opening.
For many RV garages, a door around 14 feet high is considered a useful starting point, but the right height depends on the actual vehicle and building design. Larger RVs or owners who want more flexibility may choose a taller opening.
Don’t assume one size works for every RV.
Door width matters, too
Height gets most of the attention, but width is just as important.
A large motorhome needs room to enter without constantly worrying about the mirrors or sidewalls. A wider door can also make it easier to bring in a trailer, fifth-wheel, boat, or large equipment later.
Think about the driveway approach as well. A wide garage door doesn’t help much if the driveway forces a tight turn right before the opening.
A Practical 50×100 RV Garage Layout
With 5,000 square feet, you have plenty of options.
One simple approach is to divide the building by function rather than filling it with walls.
For example, a 50×100 building could include a long RV parking area, several vehicle spaces, and a workshop at one end. The exact dimensions should be adjusted to your vehicles and how much working space you need.
Layout idea: RV and vehicle storage
You might reserve one side or part of the building for the RV and use the rest for cars, trucks, trailers, or equipment.
This works well if the building’s main purpose is storage.
Keep enough open floor space around the RV for doors, storage compartments, maintenance, and walking. Don’t plan the parking area so tightly that every vehicle has to be moved just to access another one.
Layout idea: RV plus workshop
If you enjoy woodworking, mechanical work, welding, or farm repairs, a workshop may be more valuable than extra parking.
A common approach is to place the workshop at one end of the building. This keeps tools, benches, compressors, and storage in one area while leaving the main floor open for the RV.
A wall between the shop and parking area can also help keep dust, noise, and sparks away from vehicles.
If you want a building that combines vehicle storage with workspace, looking through garage and workshop blueprintscan provide useful layout ideas.
Layout idea: open multipurpose building
You don’t necessarily need many interior walls.
A large open floor can be useful if your needs change throughout the year. You could park the RV in one area, move equipment into another, and use part of the building for seasonal storage.
This approach also gives you more flexibility if you change vehicles or equipment later.
Don’t Forget RV Turning and Approach Space
The inside dimensions aren’t the only measurements that matter.
An RV needs enough room outside the building to approach the door at a comfortable angle. This is especially important on a narrow lot or where the driveway is close to a property line, fence, or another building.
Before finalizing the garage location, think through the entire path:
road or driveway → approach → garage door → parking position
If possible, sketch the turning path using the actual length and width of your RV. A professional designer or site planner can also help check vehicle access for the property.
The same applies to trailers. A fifth-wheel or travel trailer can behave differently from a motorhome, especially when backing into a building.
What Should Go Inside a 50×100 RV Garage?
A large building can become cluttered surprisingly fast.
Plan storage early instead of treating it as an afterthought.
Wall-mounted shelving, cabinets, overhead storage, and dedicated equipment areas can help keep the floor open. Leave clear access around electrical panels, mechanical equipment, doors, and other areas that need service.
You may also want space for:
- RV supplies and spare parts
- Lawn and farm equipment
- Hand tools and power tools
- Workbenches
- Compressors
- Tires
- Outdoor gear
- Seasonal items
- Extra vehicles or trailers
If you plan to use the building mainly as a workshop and storage area, shed and workshop plans can also give you ideas for organizing smaller work areas inside a much larger structure.
What Does a 50×100 RV Garage Cost?
There isn’t one reliable price for a 50×100 RV garage.
The total cost can vary widely based on the location, site conditions, building system, materials, labor, foundation, insulation, doors, electrical work, plumbing, interior finishes, and local requirements.
A basic shell and a fully finished garage are two very different projects.
For example, costs can increase if you add:
- Multiple oversized garage doors
- Insulation and interior liner panels
- Heating or cooling
- Extensive electrical service
- Plumbing
- Concrete work beyond a basic slab
- Finished workshop space
- Bathrooms
- Storage rooms
- More windows and doors
- Higher-end exterior finishes
Site preparation can also have a major effect on the budget. Clearing, grading, drainage, and soil conditions should be considered before comparing building prices.
Instead of relying on a single cost-per-square-foot number, it’s better to create a project budget with separate allowances for the site, foundation, building shell, doors, electrical, interior work, and other improvements.
Pole Barn or Metal Building for an RV Garage?
Both pole barn and metal building designs can be used for large vehicle storage, but the best choice depends on your property, budget, construction preferences, and local requirements.
A pole barn can be a practical option for a large open building, especially when you want a simple structure with flexible interior space.
A steel or metal building can also work well for an RV garage and may offer different options for framing, exterior finishes, insulation, and interior layout.
Whichever system you choose, the structural design needs to account for the conditions at your site. Local snow, wind, soil, foundation, and other requirements can affect the final design, so the building should be designed and approved according to the rules that apply where you’re building.
Should You Add Living Space?
A 50×100 footprint gives you enough room to consider more than vehicle storage.
Some owners may want an office, guest area, bathroom, or living space connected to the garage. Others may eventually want a larger barndominium-style building with both living and shop areas.
If you are considering that route, it’s smart to plan the separation between living and garage areas from the beginning. Things like insulation, plumbing, heating and cooling, windows, entrances, and fire separation can affect the design.
For anyone thinking beyond simple RV storage, a barndominium planning guide can help you think through the living-space side of the project before you commit to a floor plan.
Plan the Building Around Your Future Needs
A 50×100 RV garage is large enough that it’s easy to overbuild one part of the building while leaving another part unusable.
Start with your largest items. Measure the RV, trailers, trucks, and equipment you already own. Then think about what you may add later.
Mark out parking spaces, work areas, storage, doors, and walkways on paper before construction begins. This simple step can reveal problems that aren’t obvious when you’re only looking at the outside dimensions.
Also think about where you want outlets, lights, water, air lines, and other utilities. It’s much easier to plan these before walls and finishes are installed.
Final Thoughts
A 50×100 RV garage gives you a lot of flexibility, but good planning matters more than simply having 5,000 square feet.
Choose the door based on your actual RV and the clearance you need. Plan the driveway and turning area along with the building. Decide how much space should go to RV storage, vehicles, equipment, and workshop use. And build your budget around the complete project rather than the building shell alone.
Before making the final decision, compare several pole barn plans and look at how different layouts handle large vehicles, storage, and work areas. A little time spent on the plan can make the finished garage much easier to use for years to come.
