Finding a safe place to park your motorhome or travel trailer should not be a difficult task. In the Treasure Valley, owning an RV is a way of life, but finding a spot to store it can cause major headaches. Kings Roofing & Contracting LLC specializes in building residential RV garages that protect your investment and add value to your home.
Whether you need a simple motorhome garage or a complex RV garage with living quarters, our team provides the craftsmanship that homeowners in the region expect. As established Boise roofers, we bring the same level of detail to our custom garage builds as we do to our award-winning residential roofing projects.
Idaho is a paradise for outdoor lovers. According to the RV Industry Association (RVIA), Idaho remains one of the fastest-growing markets for recreational vehicles, with used RV sales increasing by 5.4% over the last year alone. This surge in ownership has made on-site storage more than a luxury; it is now a practical necessity for many families.
However, the Boise climate can be tough on recreational vehicles. Intense summer sun and freezing winter temperatures damage seals, tires, and paint. Custom RV garage construction offers a permanent solution that monthly storage facilities cannot match. To ensure your new structure meets local safety standards, we coordinate closely with the City of Boise Building Department to secure all necessary permits. Additionally, we recommend checking the Idaho Department of Parks and Recreation for local trail and campsite height restrictions to ensure your new garage door height accommodates your travel plans.
Treasure Valley homeowners who invest in a dedicated residential RV garage protect their recreational vehicles, boats, and equipment from Idaho’s demanding four-season climate while adding measurable long-term value to their property. The following benefits outline why more Boise area homeowners are choosing on-site covered storage over off-site rental facilities across Ada and Canyon County.
Every property in Boise is different. We offer several garage plan options to fit your lot size and your visual preferences. Because we are a full-service exterior contractor, we can ensure your garage features professional siding installation that matches your primary residence perfectly.
An attached RV garage is built directly onto your existing home. This is a popular choice for homeowners who want easy access to their vehicle without stepping outside. We ensure the design matches your home’s siding, roofline, and exterior finishes. If you are adding an attached unit, it is often a perfect time to schedule a full roof inspection to ensure your existing structure is ready for the addition.
As experienced detached RV garage builders, we often recommend stand-alone structures for properties with more acreage. A detached building allows for a larger floor plan and more flexibility. These can be designed as a standard metal building or a traditional wood-frame structure. For these builds, many clients opt for metal roofing because of its longevity and modern appearance.
The barndominium trend is growing quickly in Idaho. We can build an RV garage with living quarters that includes a kitchen, living room, and bedrooms. This setup is perfect for an accessory dwelling unit (ADU), a guest house, or a hobby space. If you are planning a complex build like this, check out our project gallery to see the quality of our previous work.
Choosing the right size for your structure is the most critical step in the design process to ensure long-term usability. The following table outlines the minimum and recommended dimensions based on the different classes of recreational vehicles commonly found in Idaho.
RV Classification | Average Vehicle Length | Recommended Garage Width | Recommended Garage Length | Minimum Door Height |
Class A (Luxury Motorhome) | 30′ – 45′ | 16′ – 20′ | 50′ – 55′ | 14′ – 16′ |
Class B (Camper Van) | 17′ – 23′ | 12′ – 14′ | 25′ – 30′ | 10′ – 12′ |
Class C (Mid-Size RV) | 20′ – 33′ | 14′ – 16′ | 35′ – 40′ | 12′ – 14′ |
Fifth Wheel Trailer | 25′ – 45′ | 16′ – 18′ | 50′ + | 14′ – 16′ |
Travel Trailer | 12′ – 35′ | 14′ – 16′ | 30′ – 40′ | 12′ – 14′ |
A high-quality motorhome garage is more than just a big shed. It requires specific technical details to ensure it functions correctly for large recreational vehicles.
Many of our clients choose to add a workshop space or a shop area to their build. This provides a dedicated spot for maintenance work or storing equipment like ATVs, boats, or cars. To protect the foundation of your new shop, we always include professional gutter installation to move water away from the building.

A truly functional garage goes beyond simple shelter by providing the utilities necessary for vehicle maintenance and trip preparation. This checklist details the technical specifications our team follows to ensure your garage meets the highest industry standards for safety and convenience.
System | Professional Requirement | Benefit to Homeowner |
Electrical Outlets | 120V / 20-Amp (GFCI Protected) | Safe power for tools and maintenance |
RV Power Hookup | Dedicated 30-Amp or 50-Amp Circuit | Keeps batteries charged and appliances running |
Flooring | 6″ Reinforced Concrete Slab | Supports heavy weight without cracking |
Lighting | LED Overhead + Task Lighting | High visibility for evening loading or repairs |
Ventilation | Passive Ridge Vents or Powered Fans | Prevents moisture buildup and mold growth |
Safety | Fire-Rated Drywall (Attached Garages) | Meets Boise building codes for fire safety |
The RV garage cost residential projects vary based on materials and size. While a metal building or prefab metal buildings are often more budget-friendly, a custom-built stick-frame garage offers better integration with your home’s look.
In the Boise area, construction costs are influenced by local building codes and snow load requirements. While it is an investment, the savings from eliminating monthly storage fees, which can reach $400 per month for indoor, powered units in Boise, often allow the building to pay for itself over time. To help make your dream garage a reality, we offer flexible financing options to fit your budget.
Project Component | Estimated Cost Range | Impact / Value Add |
Building Permits (Ada County) | $1,200 – $1,500 | Ensures legal compliance and resale value |
Basic Metal Structure (700 sq ft) | $28,000 – $45,000 | Budget-friendly, durable storage |
Custom Stick-Built Garage | $60,000 – $120,000 | Matches home exterior; highest ROI |
Insulation & HVAC (Mini-Split) | $3,500 – $6,000 | Protects plumbing and interior seals |
Electrical (50-Amp Service) | $1,500 – $3,000 | Allows for on-site climate control and charging |
Plumbing & Cleanouts | $800 – $2,500 | Convenient waste management and cleaning |
We do not believe in one-size-fits-all solutions. Your garage plan should reflect how you live and travel.

Based on current construction data, the average cost to build a high-quality residential RV garage in the Boise area ranges from $36,000 to $140,000. Most of our clients invest approximately $90,000 for a fully finished, 700-square-foot structure. Factors such as choosing between a metal building and a stick-frame structure, as well as adding custom insulation options, will influence your final quote.
Yes. In the City of Boise and throughout Ada County, any detached structure larger than 200 square feet requires a formal building permit. At Kings Roofing & Contracting LLC, we handle the entire permitting process for you, ensuring your new motorhome garage complies with local set-back rules, drainage requirements, and the 24-inch frost line depth for foundations.
For a Class A motorhome, we recommend a garage door height of at least 14 to 16 feet. While some standard RVs sit at 13 feet, extra clearance is necessary for roof-mounted accessories like AC units and satellite dishes. We design our taller garages with these dimensions in mind to prevent any accidental damage during entry or exit.
Absolutely. This is often referred to as an accessory dwelling unit (ADU) or a barndominium. In Boise, an ADU can be up to 900 square feet or 70% of the primary dwelling’s area, whichever is less. We can design a garage apartment plan that includes a kitchen, living area, and up to two bedrooms, making it a versatile addition to your property.
Yes, significantly. Real estate trends in the Treasure Valley show that homes with residential RV garages are highly sought after. On average, a well-built garage can add a 31% premium to your home’s value. In a market like Boise, where outdoor recreation is a priority, a custom RV garage is often the deciding factor for high-end buyers.
Many HOAs in the Treasure Valley have strict “architectural harmony” clauses. This means your detached RV garage must match the exterior of your house in terms of siding color, roof pitch, and material. We specialize in matching existing finishes, from asphalt shingle roofing to specific siding installation profiles, to ensure easy board approval.
Due to the immense weight of a Class A motorhome or a large fifth wheel, we install a 6-inch reinforced concrete slab. Standard 4-inch residential slabs are prone to cracking under the weight of these vehicles. Our flooring process includes heavy-duty rebar reinforcement to ensure your foundation remains stable for decades.
While not strictly required by all codes for non-living spaces, we strongly recommend it. Treasure Valley’s winter temperatures frequently drop below freezing, which can damage an RV’s internal plumbing. By choosing high-quality insulation options and perhaps a small HVAC unit, you protect your vehicle’s seals and systems from the Idaho “freeze-thaw” cycle.
