Turn a detached garage into an ADU?

[Kash Tacke]

Hi,

I have two single family houses in Detroit currently rented out.  Both houses have detached garages and I have been considering turning the garages into 1 bedroom units.  They would be very small, approximatley 300 sf.  Right now the only utility at the garage is power so basically I am starting with a frame and a roof.  Has anyone done this before?  Any advise or lessons from your experience?

Thanks

 Cost to build is likely more than the worth of the unit. It's Detroit, not Los Angeles, just buy another house.
