Side by sides even bother me because the doors are generally right next to each other, not that I would let the get in the way of a great deal, but would prefer entrances away from one another, or at least not right next to each other.

For the new multi-family (and this was the same Texas storm @Roy N. references) we put salt on two steep stairways and in entrance ways.

You can certainly see an attorney to see if there is some entrance to a transaction but might ask the new owner as I doubt you'll be able to set them aside, which sounds to be your goal, it's too late. :)

We came up with the realization that since both of the bathrooms were rather small, especially the master (which used to be a jack-and-jill but I closed the other entrance off to make a master suite) that we could go a little bit more higher end because there wasn't much square footage.

Now to your specific questions about utilities: Electricity: If we are to take the worst case scenario: The entire property is on a single entrance and that entrance is not to modern service levels.

the entrance?

They said "evict us if you can still afford it".So we threw them out too.Now, our 2nd floor tenant, which has been ducking us on the rent, told us that we need to pay her 3200 in cash or she won't pay rent anymore either.She is saying that we owe her the money because the hallway lights are on her electric bill and it's "illegal" to be set up that way.The 3200 is for her electric bill.Thing is, it is NOT a common area. 1st floor has their own private entrance, with their own lights, on their own bill.The hallway in question is specifically for the 2nd and 3rd floors.

The basements have separate entrances behind the house.

I do not personally do business with NRIA because I do not fit their very small window of entrance.

I would envision entrance through a main hallway to individually locked spaces with security, 24 your access...etc and built specifically for document/light storage rather than cars/boats..etc.
