You could also go to an electrical supply store with your drawing and they can point you in the right direction They are a great source of the local code requirements. Your garage looks great!
I have mine enclosed for the winter and can now hopefully get some of the interior work complete. Need to complete my electrical, insulation, heat, drywall and paint. Spring I will shingle and do the siding.....and
plant some grass.....best of luck and have fun
