Need some help on getting a garage built

[Quan Booker]

I am preparing to have a garage built next to my duplex.  There has never been a garage here, but there is more than enough room with my lot being almost an acre.  Does anyone have any recommendations/suggestions for builders?  The detached garage will have electricals running to it from the duplex.  One tenant apt electricals powers the common hallways and a majority of the basement.  I was wondering, isn't it fair in this case for the electricals of the garage to be connected to the other tenant?  Thanks!
