Is there any code reference as to how far away a panel can be from where the service cables enter a house? I believe it should be as close as possible to where the cables enter, but what about a utility room in the middle of a house, 12' away from an exterior wall?

It is not specified. The AHJ makes that call. Read the comment after 230.70 in the handbook for more on this but it basically says the same thing.

12 foot seems to be a violation.
Basic rule is in 230.70 also check 230.6

What wiring method is used for the Service Entrance Conductors? The conductors can come up through the floor if the Utility Room is in the basement but I don't imagine you would have brought this up if that were the case. Type USE conductors may not extend more than six feet inside a structure because they lack a flame retardant outer covering. If the service entry conductors would have to extend twenty feet into a building and you can't encase them in masonry at least two inches thick on all sides you will have to resort to an exterior Service Disconnecting Means. Alternatively you could mount the main breaker in a flush mount enclosure at any acceptable place just inside the structure. Your main panel then becomes a feeder supplied panel and all of the rules that apply to what everyone calls "sub panels" now apply. If this doesn't actually fit your situation then sketch in some more detail and I'll try again.

I'm thinking a main breaker disconnect should be installed at the "nearest point of entrance" (or outside) and then put the panel wherever you want, except for a bathroom or kitchen.

Tom:
I'm curious as to where you obtained this info
"Type USE conductors may not extend more than six feet inside a structure because they lack a flame retardant outer covering."

Basically 'closest from point of entry into panel'; literally meaning...out of meter pan, into basement, and straight into panel' No turns, straight down into panel. That's the basic.

I have to go with Celtic, what do you mean 'not in kitchen'.

What would be wrong (Code wise, not design) with a panel in a kitchen wall??

Actually, in a home of a friend they took out the utility room, moved the water heater to a closet off the kitchen, and ended up with the panel right there next to the back door... in the kitchen (it never was moved). AHJ passed it, no changes needed.
