Do I need a common electric meter for Multifamily Chicago Homes?

[Joseph Konney]

Hello all- 

I recently acquired a 2-flat in Chicago (Cook County, Illinois) and there are only two electric meters/panels. Is a 3rd required for common areas and exterior lights? Less the inside wiring, what is an approximate cost to add a 3rd meter and panel that is just on the other side of the wall of the exterior meter? 

I had an electrician come out before the electric service was turned on and he is claiming it is necessary. The City of Chicago conservation department will soon do an interior inspection related to the previous owner's violations so I am not sure that he will even be able to pull a permit until that is done. 

Side note: I purchased a 2-flat in Forest Park (which I now live in) which only has two meters and the city of Forest Park did not flag that as an issue during the building pre-sale inspection. Possibly this was not an issue only because it was going to be owner occupied or grandfathered?

Thanks in advance for your thoughts on this!
