Four units have brand new service panel and the fifth is tied in with the whole building.

I also turn on all water and let it run to look for leaks, test outlets , look in electrical panel, etc....

Since there is no water (all copper pipes removed) and no electric (all conductors downstream of the electric panels were removed) not much one can do inspection wise except the roof.With a MF building like this do you renovate all units at the same time and get them ready for rental all in one shot?

It has never been the whole building with 4 units, but I bought a duplex that had one electric meter and we added a second panel and the electric company came in and put in a second meter.

The first project I did, I pulled a permit for which was to completely replace the electric main panel and replace the large main wires that go out to the roof. 

We actually tried that since I was replacing all of the doors with new prehung 6 panel doors anyway and when we took the measurements with everything off I still couldn't find a washer and dryer that would fit through the opening into the basement.

Old panel?

There was a panel on ADUs held by FIBI South Bay this week and a senior planner from LA (City) explained the new law.You can add two one story ADUs behind a MF building.

Gutted the entire house replaced paneling and popcorn sealings with drywall. 3.

The electrical panel looked old so it may need to be replaced.
