If we are talking about a duplex (two family dwelling), then there has to be a common area for the disconnecting means to be located in. It can't be in someones side yard where it can be behind a fence. The exception only applies when there is building mangement in place. I only have the '99 at home.
Being in different parts of the country, we may each have a different underatanding or picture in our minds of what this will look like. The way I picture this is like having my service equipment located on my neighbors house, maybe I have the wrong picture here.
This being described as a "two family complex" and being seperate buildings sent up the red flag for me.
Once 230-72(c) is satisfied, then I agree the 2nd building disconnect will be required, plus the grounding req's for 2nd buildings.
