But why didn't you keep the 70's wall paneling? 

Typically arises when a landlord has a building with a common area that has lighting, such as a foyer or hallway, but the wiring for that lighting is connected to a tenant’s electric panel and meter; it can also be something that consumes even more energy such as a laundry area that is available for all tenants in a building but the wiring goes to a single tenant’s electric panel and meter.That is why when utilities get separated in a building that the owner needs to realize that an extra panel and meter must be installed for the common areas, with billing for that common area meter going to the landlord.Some BP links that discuss this a bit more:https://www.biggerpockets.com/forums/84/topics/75044-installing-common-area-electric-in-a-3-4-unithttps://www.biggerpockets.com/forums/52/topics/107306-triplex-without-seperate-utilitieshttps://www.biggerpockets.com/forums/52/topics/72185-water-sewer-bill---what-to-do-with-it?

I was at a legal 2 flat yesterday and the listing broker said it is about a $4k job to split the panel for a 3rd unit.
