Also in CA.... A contractors' license is only required if the combined value of the work (labor and materials) is $500 or more. So Anyone can install an electrical outlet as long as the labor and materials are not more than $500....
So:
Outlet $1.00 cover plate $1.00 Old Work Box $1.00 10' of Romex $5.00 Wirenuts etc $0.25 Labor $200
So $208.25 to a handyman and presto, you've got yourself an outlet! All nice and legal like.
But also in CA (at least in San Diego) you're supposed to pull a permit to add an outlet. I'm curious what would happen if one day I walked into the planning dept and asked for an "over the counter / no plan" permit for an electrical outlet.
I'd bet they would have no clue what to do because NOBODY pulls a permit for an outlet.
I'm Not an engineer, but I play one on TV. My handle is Tweety but I have nothing to do with the organization of similar name. I just had a really big head as a child so folks called me tweety bird.
