If that's all that's on your electrical punchlist, you should feel pretty good about it. Of course, without looking at the actual situation, one can't be sure, but...

1) Electrical Service Panel: Install individual circuit breakers for circuits sharing a single breaker to reduce hazards related to double tapping. Install knock-out clamps at two+ wires entering the box to help reduce potential fire hazards.

Hard part about this one is that we don't know how many circuits are involved and whether or not the panel has room to accept any new breakers.

But if it's, say, two or three circuits and there's room to pop in new breakers, you may be looking at 1/2 hour labor and $30 in parts--rather minor, actually. Again, though, complications are possible.

The cost of the two clamps is about a buck or two--not a biggie at all.

2) Family Room: Re-wire outlets to correct polarity.

Again, we don't know how many outlets are involved, but this should just be a matter of a journeyman electrician moving a couple of wires at each incorrectly wired outlet to the correct color-coded terminal screws. With luck, no new parts will be needed and it shouldn't take more than 10-15 minutes time per outlet--maybe less.

All told, you shouldn't have to budget more than $200 total and it might even cost
