Quick answer: Plan an RV storage steel building from the RV outward. Measure the rig’s real height, length, and width, then set the door size and eave height from those numbers with room to spare, and decide whether you want a fully enclosed garage or an open-sided cover. The concrete slab and the apron in front of the door have to carry a heavy vehicle, so DGS Concrete & Steel Structures pours the foundation directly, helps you order the steel building through a trusted manufacturing partner, and coordinates both as one project.
An RV or camper parked in the open in North Carolina takes a steady beating from summer sun, heavy rain, humidity, and the occasional hailstorm. Roof seals dry out, decals fade, tires crack, and moisture works its way inside. A steel building gives the rig a dry, shaded, lockable place to sit between trips. Owners who start researching RV storage steel buildings NC soon learn that the building itself is the easy part. The planning that matters is sizing for the vehicle, picking the right doors, and building a slab that can carry the weight.
DGS Concrete & Steel Structures is an established North Carolina contractor based in High Point. DGS handles the concrete and foundation work directly, helps you select and order the steel building through a trusted manufacturing partner, and then coordinates the slab and the structure as one project. For an RV building, that coordination covers the anchor bolt pattern, the slab edge, the door apron, and the timing between the pour and the installation. Every building in this guide is a non-dwelling storage building, made for parking and protecting a vehicle and the gear that goes with it.
Measure Your RV Before You Pick a Building Size
The right building size starts with three measurements of the RV you own today, and ideally the one you might buy next. Height should be taken from the ground to the tallest item on the roof, which is usually the air conditioner shroud, a satellite dome, an antenna, or a solar panel rack, not the roof itself. Length should run from the front bumper to the rear ladder, bike rack, or spare tire, and for a towable unit it should include the hitch or tongue. Width should include the mirrors and the awning housing. If you ever want to open the slide-outs inside the building to air out the RV or do maintenance, measure the width with the slides fully extended.
North Carolina sets an outside limit on how big a road vehicle can be. North Carolina’s vehicle size law, G.S. 20-116 caps vehicle height at 14 feet and width at 102 inches, and it allows recreational vehicles up to 45 feet long, not counting bumpers and mirrors. Those figures are a ceiling for the road, not a target for your building. A road-legal RV will fall inside them, so measure your own vehicle rather than designing around the legal maximum, and then add working room on every side so you can walk around the RV, open the storage compartments, and reach the roof ladder.
The table below shows what to measure closely for the most common RV and camper types.
| RV or Camper Type | What to Measure Closely | What It Means for the Building |
| Class A coach | Height to the top of the roof units, full length, and mirror width | Tallest door and eave height, a long bay, and a wide opening for the mirrors |
| Class C or Super C | Height of the cab-over and roof units, and length with any rear rack | Tall door, plus extra length if a bike rack or tow bar stays attached |
| Fifth wheel trailer | Height at the front cap and roof units, and length including the pin box | Tall door, long bay, and turning room for the truck to back it in |
| Travel trailer | Length including the tongue and jack, and roof unit height | Moderate height, with room at the front for hitching and unhitching |
| Camper van or truck camper | Height with roof vents and racks, and overall length | A shorter bay that can share a building with a workshop or trailer |
| Boat or utility trailer | Length with the trailer tongue, and height of the boat or load | Can share the RV building if the bay is long or wide enough |
How to Set Door Height, Door Width, and Eave Height
The door opening and the eave height are the two numbers that decide whether your RV fits, and both should be set from your measured RV height with a margin, not from a stock building size. A tall door in a short building does not work, and a tall building with a short door does not either.
Roll-Up Door Height and Width
The roll-up door opening should be taller than the highest point on your RV with clearance to spare, so the roof units never brush the door when the suspension rocks over the apron. Door width matters just as much. An opening that barely clears the mirrors turns every trip into a slow, nervous back-in, while a wider door gives the driver room to correct. If the lot allows it, a drive-through bay with a door on each end lets you pull a long fifth wheel or Class A coach straight in and straight out with no backing at all.
Eave Height and Interior Clearance
The eave height of an RV building has to be higher than the door opening, not equal to it. A roll-up door coils onto a drum above the opening, and that drum and its header need space inside the wall. The steel frame also has rafters and bracing that sit below the roof line, so the clear height under the frame is less than the eave height printed on the order. Ask for the clear height under the frame in writing, and check it against your RV height plus the clearance you want.
Walk-In Door and Windows
A walk-in door lets you check on the RV, grab gear, or plug in a battery maintainer without opening the big door. Place the walk-in door where you will actually approach the building, usually on the side facing the driveway. Windows bring in daylight so you can work without lights, and they should sit high enough that an open compartment door or a mirror will not hit them. Every door and window is a framed opening in the steel building that changes how the walls handle wind, so lock in the layout before the building is ordered.
Enclosed RV Garage or Open-Sided RV Cover
A fully enclosed RV garage gives the most protection and security, while an open-sided RV cover blocks sun, rain, and hail at a lower cost. The right choice depends on what you are protecting the RV from and how much the building needs to keep out.
An enclosed RV garage shuts out wind-driven rain, blowing dust, pollen, birds, and rodents, and it can be locked. That matters on rural properties where an RV sits out of sight for weeks, and on any property where theft or vandalism is a worry. Enclosed walls also give you places to mount shelves, hang hoses and cords, and run lighting and outlets.
An open-sided RV cover still keeps direct sun off the roof seals, tires, and paint, and it sheds rain and hail. An open cover uses fewer components and costs less, but it leaves the RV exposed to blowing rain, humidity, and pests, and it offers no security. Some owners choose a middle path with one or two walls closed in on the side that faces the worst weather. DGS can quote both enclosed and open designs so you can compare them for the same RV on the same site.
Plan the Slab and the Apron for a Heavy Vehicle
An RV storage building needs a concrete slab designed for a heavy vehicle, because the weight of a loaded RV is carried through a few tires and, at times, leveling jacks that press down on small pads. That load lands on the same spots every time the rig is parked, and it is far heavier than a car or a lawn tractor. The slab thickness, the reinforcement, and the compacted stone base below it should come from the RV’s weight and the soil on your site, not from a rule of thumb.
The apron in front of the door deserves as much attention as the floor inside. The apron is where the RV rolls from gravel, asphalt, or grass onto concrete, and a weak or settled apron cracks first. A good RV apron is wide enough for the tires to stay on concrete while the driver lines up, meets the floor without a lip, and slopes away from the door so rainwater does not run into the building.
Soil makes a real difference in North Carolina. Clay soils common across the Piedmont hold water and can swell and shrink, while sandier ground in parts of the Coastal Plain drains fast but can sit over a high water table. Our article on how site conditions shape concrete and steel success covers grading, drainage, and soil in more detail. The slab also has to match the building. The anchor bolt pattern, the slab dimensions, and the slab edge detail all come from the steel building’s drawings, which is why DGS pours the slab with the specific building in mind rather than pouring first and hoping the building fits.
Leave Turning Room on the Lot
Turning room is the open space a driver needs to swing the RV or tow vehicle around and line up straight with the door, and it often decides where an RV building can go. A long fifth wheel or Class A coach needs a wide, clear approach in front of the door, free of trees, fences, ditches, and parked cars. Overhead power lines and low tree limbs need a look too, because they can stop a tall rig short of the building.
Place the door so the driver can pull forward past the building and back straight in, or choose a drive-through bay. The drive leading to the apron should be firm enough to carry the RV in wet weather. Building placement also has to respect setbacks, easements, and any neighborhood or HOA rules. Permit and zoning requirements vary by city and county, so verify locally before the building location is final.
Control Humidity and Condensation Inside the Building
Humidity is the hidden risk in RV storage across North Carolina, and an enclosed steel building needs ventilation and condensation control to keep moisture off the RV. Bare steel roof panels cool quickly at night. When warm, damp air meets that cold steel, water condenses on the underside of the panels and can drip onto the RV roof. Over a long storage season, that moisture can feed mildew inside the RV and rust on the chassis.
A few simple features handle most of the moisture problem in an RV building.
- Insulation or a condensation control layer under the roof panels
- Ridge vents, gable vents, or wall vents that let damp air escape
- A vapor barrier under the concrete slab to slow ground moisture
- A slab and apron graded so rainwater drains away from the door
- An electrical outlet for a battery maintainer, fan, or dehumidifier
Ask for insulation and vents to be listed on your quote, because they are much easier to include in the order than to add after the building is up.
Add a Workshop Bay Beside the RV
Adding a workshop or garage bay next to the RV bay gets more use from the same slab and site work, and it is far easier to plan at the start than to add later. The RV side stays tall while the workshop side can use a standard door, giving you space for tools, a workbench, a mower, or a boat. Think of it as two buildings under one roof, an RV garage on one end and one of the metal workshops NC property owners use for repairs and hobby projects on the other.
A lean-to on the side of a tall RV building is another way to gain covered space for a trailer or equipment. Whichever layout you choose, plan the slab, the doors, and the power for both spaces at once, so the floor levels, anchor bolts, and drainage all work together. The workshop bay serves the same non-dwelling purpose as the RV bay, which is tools, maintenance, and storage.
What Drives the Cost and How to Compare Quotes
The cost of an RV storage steel building depends mainly on its height, its footprint, whether it is enclosed or open, the number and size of doors, insulation, the slab, and the site work needed to reach it. Height weighs more on an RV building than on most storage buildings, because a taller building needs taller columns, more wall panel, and larger doors.
When you compare quotes, make sure each one covers the same complete scope, because a building price on its own leaves out the slab, the apron, grading, delivery, and installation. A complete quote should list the clear height under the frame, the door sizes, the slab design, and the site work included. If you are weighing how to pay for the project, our guide on rent to own versus financing for a metal building explains the two general paths, and you can ask DGS which parts of the project each option can cover. Comparing RV storage steel buildings NC is much easier when every quote describes the same building on the same slab.

Frequently Asked Questions
- How tall should the door be on an RV storage building?
The door should be taller than the highest point on your RV, measured to the top of the air conditioner, antenna, or satellite dome, with clearance to spare. The building’s eave height then needs to sit above the door so there is room for the roll-up door drum and the steel frame. DGS can review your measurements and help you set both numbers before the building is ordered.
- Can DGS pour the slab and coordinate the steel RV building as one project?
Yes. DGS pours the concrete slab and apron directly, helps you select and order the steel building through a trusted manufacturing partner, and coordinates the two as one project. That means the anchor bolt pattern, the slab size, and the door apron are all set to match the building you order.
- Should I choose an enclosed RV garage or an open RV cover?
Choose an enclosed garage if you want protection from wind-driven rain, dust, pests, and theft, and choose an open cover if shade and rain protection at a lower cost are enough. An enclosed building also gives you walls for storage and lighting. DGS can quote both for the same RV and site so you can compare.
- Do I need a permit to build an RV storage building on my property in NC?
Permit and zoning requirements vary by city and county, so verify locally what applies to your parcel and building size. Setbacks, easements, and any HOA rules can also limit where the building sits. Check early, before the building location and size are final.
- Can I add a workshop or boat bay to my RV storage building?
Yes, a combination building with an RV bay plus a workshop, garage, or boat bay is a practical way to get more from one slab and one project. Plan both spaces at the start so the slab, doors, drainage, and power work together. The added bay is for tools, maintenance, and storage.
- How much does an RV storage steel building cost in North Carolina?
There is no single fixed price, because cost depends on the building height and size, enclosed or open sides, doors, insulation, the slab, and site work. The quickest way to a real number is an itemized quote for your RV and your site. Ask DGS about the rent-to-own and financing options available for your project.
