said by stev32k:That's pretty amazing. I knew the building costs were higher, but didn't realize they were that much higher. My brother-in-law just had a 3-car, 30' X 35' garage built. It is brick veneer, finished inside, but not insulated and does not have storage space above. His total cost was a little under $35,000 or about $33/ sq ft.
Sooooo many factors go into new construction you can't compare them without it all. Foundation is a huge one. Most people can just have a slab poured and the foundation might run $3,000-5,000. Others like myself have a major slope to deal with so that same foundation is $25,000. Most people just use OSB sheathing and 2x4 framing but I used plywood and 2x6. A normal unconditioned garage might only need cheap windows but mine has energy star rated windows. With no room above the garage you don't need a firewall, stairs, etc. either. Different towns/states have different requirements on building. Most don't need a certified plot plan but mine did so add $1,500 right there. Most don't need a engineering stamp either so add another $1,500 there. Mine had demo costs to remove the old garage and dispose of the waste for $3,200. A new garage doesn't have that. My garage has 2 fire doors and 2 external doors. Most garages don't have that either. My garage has a 60amp subpanel and again most garages don't have that either. It's hard to compare your brother-in-law's garage to anyone else's without all the info.
