RV Garage Cost

I think it would be wood with a sutuco exterior and flat roof. Wired for lights and outlets and that it...

Labor in our area would be on the low side.

Over here on the other side of the OR/ID line, I just got an estimate from our contractor and his quote was $40/sq ft, plus any utilities we wanted. This was for a 30' x 50' steel pole barn type building with 14' eaves and a 12x14 RV door, one man door and windows every 10 feet. That would include spray on foam insulation and 6000 psi floor with footers.

Go ahead and call a contractor and get a quote. Too many variables for any of us to "guesstimate" a cost of construction.

Depends on labor cost in your area for one.
Wood, brick or a Pole Barn.
You want a Full Hook Up inside?
Heat to keep the dampness out.
Cealing fan or two to help dry things out.

We had a 30'x40' pole barn. Cost was a very long time ago.
Have a 68' attached garage now. Cost of garage was in house build so can not help with that.
