I currently own a 6-plex in a 10,000 sq ft building. There was 1200 sq ft of open space that used to be a store. Im building 2 additional apartments using this space. Im wondering if anyone knows the cost of adding 2 additional electric meters to the house. National Grid will not give a quote over the phone without filling out a work order. My dilemma is I may just keep them on the house meter if its too much. I just need a ball park quote.
