There are so many posts on this forum that ask about building costs so I though I would share some of the sub-contractor costs for this build. You can get a sense of the scope by reading through this thread. This hasn't really been a typical garage build as our location has dictated that we do some things differently than someone putting a garage on a piece of property in a rural area.
In general, the job was constructing a brand new 1074 sq. ft. (interior dimension) garage along with converting a 541 sq. ft. existing garage into dwelling space and a small overhang linking the two. Most cost categories consisted of multiple bids and I, as the owner, had to sign off on each chosen sub-contractor.
I know that some of you will have opinions on these costs relative to your experience or expectations. Two things to keep in mind are location (Chicagoland suburbs) and timing (construction during spring and summer of 2021). Judge these numbers in that context.

There were additional smaller costs that added up but I didn't include them as they may not be part of a different garage project. Additionally, the general contractor received a fee that was a percentage of sub-contractor cost. This fee was also not included.
The result was pretty much turn-key. The only thing I have done after completion was purchase and install lighting in the garage ceiling.
I would be happy to answer any questions, just ask.
