Two and a half years in, we are FINALLY sucking it up and hiring someone to finish the garage apartment. This is the before photo from the entrance doorway looking in. It's a very good size, and has good light from all the windows.
I'll be sharing progress photos soon. The crew says they will be done in 3 weeks. The painting and some of the finishing will be completed by 'us' after the paid crew leaves.
Edit 1/3/2015: I had a comment today asking if there was an exterior photo of the apartment, so I am inserting the photo below. The apartment is the upstairs portion of the garage.
