An important issue, that seems to be left out, is to be sure you check with your local Commissar.
Any belief you have that you own your house (and therefore can make reasonable and minor modifications) will be quickly dispelled. In fact, for most, the bank owns yours house and you are simply a source of funds. If, by some fault of the system, you escape that, then your home is owned in the following order:
1. Your HOA.
2. Your City goverment.
3. Your County govenrment.
4. Dept. of Homeland Security.
5. Dept. of Redundancy Department.
6. Your Home Owners insurance company.
7. Your Health insurance company.
8. Barring #7, then by your doctor - oh face it, it is just a matter of time until you owe him EVERYTHING.
9. Any "environmentalist" that thinks anything other than people live on "the" (not your) property.
(This happened to me - ever heard of an "eagle"?)
10. Your lawyer, if you ever make a mistake, or if you don't agree with any of the above.
But less seriously, I was an electricians apprentice at one point in my life. Went to school a couple of months and then was placed in the field. It was expected that I wire an entire house from the breakers, to the outlets, to the switches, to the fluorescents, to the door bell, to the bathroom fans, to stuff I can't remember, in about 6 hours.
Quality control consisted of turning everything on and see if it worked. Usually one thing didn't, and the wirenuts were tightened. I sincerely hope you do not own one of those houses.
However, if you think you do, NEVER attempt to check things without proper govermental authority. It's only right. Never trust yourself, unless someone tells you it is OK.

P.S. And remember, no reading of books on the subject, information in the wrong hands is DANGEROUS! (In my opinion those books (especially electrical ones) should be BANNED and then BURNED - they promote a false sense of security.)
