RV Garages
Frequently asked questions
-
What size garage do I need for an RV?
Your required garage size depends on motorhome class, length, height, and whether you need to store additional vehicles or require shop space.
Class A motorhomes need the most space, while Class B vans fit smaller garages. Travel trailers and Class C RVs fall in between.
Always plan interior clearance beyond the RV footprint for doors, mirrors, and maneuvering.
Here are our standard metal building size recommendations for popular setups:
RV Class RV Only Dimensions (WxLxH) RV + 2 Cars Class A 20x30x16 or 20x50x16 30x30x16 or 30x50x16 Class C 20x25x14 or 20x35x14 30x25x14 or 30x35x14 Class B (van) 15x20x12 or 20x30x12 25x20x12 or 30x30x12 Travel trailer 20x25x14 or 20x35x14 30x25x14 or 30x35x14 5th wheel 20x25x14 or 20x35x14 30x25x14 or 30x35x14 -
How tall should an RV garage door be?
Most RV parking garages use doors between 12 and 14 feet tall, with 12 feet being a typical “safe minimum” and 14 feet preferred if you own (or might upgrade to) a large Class A or Super C.
Typical recommended heights
Guidance from RV and door suppliers typically puts Class A and Super C garage door height in the 12–14 foot range to comfortably clear coaches that are 11–13.5 feet tall plus roof accessories.
How to choose your height
- If you plan only for smaller Class B/B+ rigs or camper vans, a 10- or 12-foot door may be enough, since many of these are 7–10 feet tall.
- For flexibility and property resale, we recommend a 12-foot-tall by 12-foot-wide RV door, with 14 feet of height if you want to future‑proof for any highway‑legal Class A or Super C (max vehicle height is generally 13.5 feet).
Practical rule of thumb:
Measure the tallest point on your current or planned rig (including A/C, satellite, roof racks, etc.), then add at least 1–2 feet of clearance; in practice, this usually gives you a 12–14-foot-tall door for RV use.
Also, be aware that doors for pre-engineered metal buildings must be 2’ below the eave height, so for a 14’ door, you will need to specify a 16’ eave height. Maintaining a minimum clearance of 2 feet between openings and the building’s corners or roofline is critical for structural integrity, code compliance, and weatherproofing.
Note: For buildings with bypass sidewalls, manufacturers often recommend adding an extra 8–10 inches to this minimum distance to account for the depth of bypass girts.

How much do RV garages cost to build?
The average turnkey cost to build a motorhome garage ranges from $20,400 to $34,000 for a Class A garage, from $17,000 to $23,800 for a Class C, and from $10,200 to $17,000 for a camper van. This includes the building kit package, concrete foundation, and professional installation.

Will a recreational vehicle garage add value to my property?
Well-designed, permitted pre-engineered metal RV garages almost always add value. In many markets, expect 5–15% added property value, with the best results in markets where garages and shop space are in high demand.
-
What are my options for installation?
When it comes to erecting your building, you have three options.
Do-it-yourself (DIY). We only advise going this route for smaller buildings (under 2,000 square feet) and for those with previous construction experience.
Self-manage. With a self-managed outline, you are responsible for hiring and managing the various sub-trades, including the concrete company for the foundation, the steel erectors to construct the kit, plumbers, electricians, etc.
Hire a General Contractor (GC). For a completely hands-off option, consider hiring a GC who will manage the entire design on your behalf, from pulling permits and installation to the final inspection. Expect to pay 10-20% for a GC's services.

Why are your metal buildings more expensive than other options I have seen online?
Our suppliers exclusively offer commercial-grade Pre-Engineered Metal Buildings (PEMBs) featuring solid steel I-beam framing.
In contrast, most buildings sold online are light-gauge tubular structures. Since steel is priced by weight, and tubular buildings weigh less than half as much as a PEMB, the cost difference reflects the significantly greater volume of steel and the structural durability of our products.
It’s a classic case of apples and’ oranges! -
What an RV will fit in a standard size garage?
Standard residential garages (typically 12x20 ft for single-car, 20x22-24 ft for two-car, with 8-10 ft door heights) will only accommodate compact RVs like Class B motorhomes, teardrop trailers, pop-up campers, and small truck campers.
