# Steel RV and Boat Storage Buildings in Arkansas: Sizes, Costs, and Design Options
A Class A motorhome sitting in a driveway fades faster than most people realize. UV damage, hail, ice, and Arkansas humidity take years off paint, rubber seals, and roofing membranes. A steel storage building solves the problem permanently, and in Northwest Arkansas and the River Valley, more property owners are building dedicated RV and boat storage structures every year.
D&P Steel Erection has been building steel structures across Arkansas for over 17 years. Below is everything you need to know about planning, sizing, and pricing a steel RV or boat storage building in Arkansas.
Why Steel Works for RV and Boat Storage
Wood-frame pole barns have been the default in rural Arkansas for decades, but steel outperforms them in every category that matters for vehicle storage.
Durability. Steel buildings resist rot, termites, and mold. In the Fort Smith area and across the Arkansas River Valley, humidity levels regularly exceed 80 percent in summer. Wood framing absorbs that moisture and degrades over time. Steel does not.
Clear-span design. RVs and boats need wide, unobstructed interiors. Steel allows clear spans up to 200 feet with no interior columns. A 40-foot-wide building with a single open bay is standard for most RV owners, and steel makes it straightforward.
Low maintenance. A quality steel building with a 26-gauge painted panel system needs almost nothing beyond occasional washing. No repainting, no replacing rotted boards, no re-shingling every 15 years.
Speed of construction. Most steel RV storage buildings in the 30x50 to 40x60 range go up in two to four weeks once the slab is poured. A comparable wood-frame structure takes significantly longer.
What Size Building Do You Need?
Sizing is the most common question, and getting it wrong is expensive. Here are the standard dimensions that work for most RV and boat combinations.
Single-Vehicle Storage
| Vehicle Type | Minimum Width | Minimum Length | Recommended Door Height | |---|---|---|---| | Class A Motorhome | 14 ft | 40 ft | 14 ft | | Class C Motorhome | 12 ft | 30 ft | 12 ft | | Fifth Wheel | 12 ft | 38 ft | 14 ft | | Travel Trailer | 10 ft | 28 ft | 12 ft | | Bass Boat on Trailer | 10 ft | 26 ft | 10 ft | | Pontoon on Trailer | 12 ft | 30 ft | 12 ft | | Ski Boat on Lift | 12 ft | 28 ft | 12 ft |
Multi-Vehicle and Combination Storage
Most Arkansas property owners who build a storage structure want room for more than one vehicle. A 40x60 building comfortably fits a Class A motorhome and a boat, with room left for an ATV or workshop area along one wall. A 50x80 building handles two large RVs side by side or an RV, a boat, and a full workshop bay.
Add three to five feet of clearance on each side of the vehicle for comfortable maneuvering. If you plan to work on your boat or RV inside the building, add at least eight feet of extra length.
Door Options for RV and Boat Access
The door is the most critical component. An undersized door turns every pull-in and pull-out into a stressful experience.
Roll-up doors are the most common choice. A 14x14 roll-up accommodates the majority of Class A motorhomes. Wind-rated roll-ups are worth the upgrade in the Arkansas River Valley, where straight-line winds regularly exceed 60 mph during spring storm season.
Hydraulic doors offer a clean, modern look and can span wider openings without a center column. They cost more than roll-ups but provide a single unbroken opening that simplifies maneuvering a 45-foot motorhome.
Sliding doors work well for boat storage where height is less of a concern. They are durable, low-maintenance, and do not require the overhead clearance that roll-ups need.
For most RV storage buildings in Arkansas, we recommend at least one 14-foot-tall opening for the primary bay and a standard walk-through door on a side wall for everyday access without opening the main door.
How Much Does a Steel RV Storage Building Cost in Arkansas?
Pricing depends on size, foundation type, door configuration, and whether you add insulation or electrical. Here are realistic ranges for completed buildings in the Fort Smith and Northwest Arkansas market as of 2026.
| Building Size | Estimated Cost (Turnkey) | Notes | |---|---|---| | 30x40 | $28,000 - $38,000 | Single RV or boat, basic | | 40x60 | $42,000 - $58,000 | RV + boat, most popular | | 50x80 | $65,000 - $90,000 | Multi-vehicle, workshop space | | 60x100 | $95,000 - $130,000 | Commercial or multi-bay |
These ranges include the steel building package, erection, a standard 4-inch concrete slab, one roll-up door, and one walk-through door. Insulation, electrical, plumbing, and upgraded doors add to the total.
Factors that affect your price:
- Site prep. Clearing, grading, and drainage work vary by property. A flat, cleared lot in Alma costs less to prepare than a wooded hillside in the Ozarks.
- Insulation. Spray foam or batt insulation adds $2 to $4 per square foot but protects your RV from condensation and temperature swings.
- Electrical. A basic panel with lights and outlets runs $2,000 to $4,000. Shore power hookups for RV battery charging add $500 to $1,000.
- Permitting. Building permits in Arkansas vary by county. Sebastian County, Washington County, and Benton County each have different setback and size requirements. We handle the permit process for every project we build.
Insulation: Do You Need It?
If you are storing a vehicle you care about, insulation is worth the investment. Arkansas temperature swings from 15 degrees in January to 100 degrees in July create condensation inside an uninsulated metal building. That condensation settles on your RV roof, boat upholstery, and electronics.
A minimum of R-13 wall insulation and R-19 roof insulation keeps interior temperatures stable enough to prevent condensation in most conditions. Spray foam performs best because it seals gaps and acts as a vapor barrier simultaneously, but fiberglass batts with a vapor barrier work well at a lower cost.
If the building is strictly cold storage and you do not plan to spend time inside, you can skip insulation, but be aware that moisture issues will develop over time.
Building Permits in Arkansas for RV Storage
Permit requirements vary by county across Arkansas. In unincorporated areas of Crawford County or Franklin County, you may need nothing more than a septic setback verification. In the city limits of Fayetteville, Rogers, or Bentonville, you will need a full building permit with engineered drawings and a site plan.
D&P Steel Erection handles permitting for every project. We know which jurisdictions require engineered stamped plans, which allow owner-builder permits, and which have specific restrictions on accessory building height or square footage.
Key things to confirm before you build:
- Setback requirements. Most Arkansas counties require 10 to 25 feet from property lines.
- Height restrictions. Some HOAs and city ordinances cap accessory building height at 20 feet. A 14-foot door plus roof pitch may push past that limit.
- Flood zones. Properties along the Arkansas River, Illinois River, or in low-lying areas of the River Valley may require elevated foundations.
Commercial RV and Boat Storage Buildings
If you are building storage units for lease rather than personal use, steel is the only material that makes financial sense at scale. A 60x120 building with six 12x30 bays generates revenue from day one, and the maintenance costs are minimal compared to wood-frame construction.
The demand for covered RV and boat storage in Northwest Arkansas has grown steadily. Beaver Lake, Lake Fort Smith, Illinois River access, and the Ozark mountain trail systems bring thousands of recreational vehicles into the region. Covered storage commands $150 to $300 per month per bay in the Bentonville-Rogers-Fayetteville corridor, and waitlists are common.
If you are considering a commercial storage venture, we can help with site layout, bay sizing, and building configuration to maximize your return.
Frequently Asked Questions
How long does it take to build a steel RV storage building? Most residential RV storage buildings in the 30x40 to 50x80 range take two to four weeks for erection after the foundation is complete. Foundation work typically adds one to two weeks depending on weather and site conditions. Total project timeline from contract to completion is usually six to ten weeks.
Can I add living quarters to my RV storage building? Yes. A steel building with an attached or integrated living space is essentially a barndominium, and D&P Steel Erection builds those as well. We can design the storage bays on one side and finished living quarters on the other, all under one roofline.
Do I need a concrete slab? For RV and boat storage, a concrete slab is strongly recommended. Gravel floors work for equipment storage, but the weight of a loaded motorhome or boat trailer causes rutting in gravel over time. A 4-inch slab with fiber mesh reinforcement is the standard specification.
What wind load rating should I specify? Arkansas building codes generally require a minimum 90 mph wind load rating. In the River Valley and tornado-prone areas, we typically build to 110 mph or higher. Higher wind ratings add minimal cost and significantly improve the building's long-term performance.
Will a steel building rust in Arkansas humidity? Modern steel buildings use Galvalume-coated panels with baked-on paint finishes rated for 40 years. Rust is not a concern with quality panels and proper installation. We use 26-gauge Galvalume as our standard panel, which is the industry benchmark for longevity.
