Overview
About the 18x30 RV Garages
This 18x30 Class A steel RV garage gives you 540 sq. ft. of enclosed steel space for select motorhomes, campers, oversized vehicles, trailers, tools, and outdoor gear.
The 18-foot width gives you room for parking and side clearance. The 30-foot length works for shorter RVs, campers, trailers, and equipment storage. Before ordering, measure the full RV height, including the AC unit, vents, ladder, and roof accessories. The included 10x10 roll-up door fits some RV and camper setups, but taller Class A motorhomes may need a larger custom door and more building height.
This garage has a 12-foot height, vertical roof system, one 10x10 roll-up garage door, 14-gauge steel frame, and 29-gauge sheet metal panels. The vertical roof helps rain, snow, leaves, and debris move off the building better.
Shown in Pebble Beige with Black trim, this building gives you enclosed protection for travel gear, vehicles, and equipment you don’t want sitting outside.
Every building is custom made. You can change the height, door size, colors, roof style, insulation, anchors, panel layout, and certified wind or snow options based on your RV size, property, and local code needs.
Delivery and professional installation are included. Call Garage Buildings to get your 18x30 steel RV garage quote.

FAQ
Frequently Asked Questions about 18x30 RV Garages
What sizes are available for commercial metal buildings?
Our commercial metal buildings range from 30x40 for small businesses up to 100x200+ for large warehouses and industrial facilities. Clear-span designs eliminate interior columns, giving you maximum usable floor space for your operation.
What is the most popular metal garage size?
The most popular sizes are 24x30 and 30x40 for residential use. A 24x30 comfortably fits two vehicles with workspace, while a 30x40 provides room for a full workshop. We offer sizes from 12x20 all the way up to 60x100+.
What size building do I need for my RV?
Measure your RV and add at least 2-3 feet on each side and 2 feet of height clearance. Most Class A motorhomes need a building at least 14 feet wide, 40-45 feet long, and 14 feet tall. Class C RVs typically fit in an 18x30x12 structure.
What size metal carport do I need for two cars?
A standard two-car carport is typically 20x20 or 24x20 feet. If you want extra room for opening doors comfortably or storing additional items, consider going up to 24x24 or 24x30. Our team can help you determine the perfect size based on your vehicles.
What is the maximum size for a metal warehouse?
We build metal warehouses up to 100 feet wide and virtually unlimited length. Clear-span designs up to 60 feet wide eliminate interior columns for maximum storage flexibility. For wider buildings, interior columns can be added.
How much do metal buildings cost?
Metal building pricing depends on size, roof style, gauge of steel, customizations, and your location. Every quote is personalized to your exact needs and includes free delivery and professional installation — no hidden fees. Call us at (888) 234-0475 or request a free quote online to get your price.
What can I customize on a metal building?
Nearly everything. You can customize the size, roof style, wall height, colors, door types and placement, window locations, insulation, lean-tos, wainscoting, and more. Our design team works with you to create a building that fits your exact needs.
What size metal barn do I need for horses?
For horse stalls, plan for 12x12 feet per stall plus aisle space. A 30x40 barn comfortably houses 3-4 horses with a center aisle. For larger operations, 40x60 or 60x80 barns provide room for more stalls, tack rooms, and feed storage.
