For example, they can see your wiring diagram and know you plan on using the right sized breakers and will not overload them, you have GFCI in the proper locations, smoke alarms will be installed in all the proper rooms, etc.5.

The interior electrical work should/would be nil, and the cost of submetering won't require the installation of two new power panels, assuming you currently only have one. idk maybe @Stephen Joyner can chime in and provide some electrician professional insight on this option.Now the on the billing side of things, you would still be responsible for providing electrical service to the units as the main electric company account holder, but you would be able to bill each unit for their own proportionate share of the electric bill.

Unless there has been a natural disaster, poor installation/construction, or failure of previous board to perform the fiduciary responsibility then this was a foreseeable item.

We are planning to install new kitchens, fix up bathrooms, etc over time.

Consider the following: Installing a ceiling fan may cost you $200.00 and you may only get $10 a month more in rent.
