@Ana Mills We use electricians for all necessary electrical connections.

Haven't discussed with them as my electrician has suggested installing a device to determine kilowatt usage for the main dwelling and the ADU.For now my ADU strategy will be looking for properties with attached garages and are large enough to eventually add a detached ADU if I decide to go that route and I prove that this strategy works.  

Go Google the average current age of electricians, plumbers, etc.

All for adding an overhead light or two (generating the city approx $50 in fees) that’ll take the electrician an hour and costs you $200.

I know only carpentry, but I have friends who are electricians and plumbers as well.

Dr's, Nurses, Electricians, heavy equipment operators etc etc.. 

For the kitchen light, we did end up sending out a licensed electrician and the issue was resolved within 1 week. 4.

I have my own "go to" plumber and electrician as backups when/if something doesn't go as planned with his crew.

Our Team (bankers, contractors, excavators, attorneys, surveyors, electricians) aren't there. 

How many electricians would hang up the belt and wait to die.
