Stuck with unresponsive contractor

[Chip Cook]

Please help!!! I closed on my 1st BRRRR project in August. Hired a contractor and laid out the project. Got formal bid and have gone over the details. I paid him 1/2 of the estimate up front ($15k).

It's only about 1000 sf small home, but the guy has made little to no progress on this project 3 1/2 months later...with no end in sight.

What FORMAL actions can I take against this guy?  W/ the state (Idaho)? City? County?  BBB?  Any tips or ideas?
