What size garage door do I need for an RV?

For a Class A motorhome, plan on a 14-foot-wide by 14-foot-high door, with 16 x 14 being common. Class C motorhomes usually need 12 x 12 or 12 x 14. Class B camper vans can often use a 9 x 8. Always measure to the tallest point of your rig, typically the air conditioner, and add at least 12 inches of clearance.

How deep should an RV garage be?

Add 4 to 6 feet to the total length of your RV so the door closes behind it. A 40-foot Class A therefore wants a bay in the 44 to 46 foot range, and more if you want walk-around space at the front for maintenance.

How big does a motorhome garage need to be?

For a Class A coach, plan on roughly 16-foot sidewalls to carry a 14-foot door with its opener and track, a bay 44 to 46 feet deep, and at least 14 feet of width. That typically works out to 700 to 1,000 square feet for a single coach bay, though most plans provide considerably more so the space doubles as a workshop.

Can an RV garage have living quarters or an apartment?

Yes, and it is a common configuration. A loft above the rear of the bay is the cheapest option since the roof volume already exists. A side-by-side apartment on the same level costs more in footprint but avoids stairs. Both require the bay to be built with the sidewall height a motorhome door needs.

Is an attached RV garage cheaper than building a detached one later?

Usually. An attached bay shares the foundation, roof structure, and trade mobilization with the main house. A detached building added later needs its own slab, roof, permit, and separate mobilization of every trade, which typically costs more than including the space in the original plan.

Do I need a thicker slab for an RV bay?

Usually yes. A loaded Class A motorhome can exceed 30,000 pounds concentrated on relatively few contact points, so the RV bay typically needs a thicker, more heavily reinforced slab than the living area. Your engineer will specify thickness and reinforcement for your soil conditions.

Can I add an RV bay to a plan that does not have one?

Often yes, but it is a structural change rather than a cosmetic one. It affects sidewall height, door headers, truss design, and slab specification. It is almost always simpler and cheaper to start from a plan drawn with the bay included.
