I only know my particular area, but as a homeowner, I can do any electrical work I want on my dwellings. If I owned a rental, I couldn't do electrical work on that. I still have to pull permits and pass inspections, but it's really not as bad as most people assume. Just do competent work and check your wire gauge derating math a few times before you start pulling things. My main panel, outside, is effectively "half mine, half the power company's." The side with the meter in it is tagged off and I can't get into it without going through power company indicators. But everything on the other side, with the breakers, is my problem. Then everything from the box out to the pole transformer is the power company's problem. Again, this isn't going to be broadly true everywhere, but that's the usual breakdown of things, and outside a few areas in the US, you are legally permitted to do electrical work on your residence. I mean, I did my own massive ground mount solar install, grid tied, without having to bother an electrician. It just required the normal permitting process and such.
