depends. most need permission from landlord, developer and electric company regarding connections and insurance. old developments are harder than new ones due to amperage (?) surplus. electricity is billed as all other equipments in the same zone. we have no differencial pricing besides industrial (lower) vs domestic (higher).
not easy and it really depends on individual owners. As a lucky one, I had worked for almost 1 year to get it approved and with charger installed. As it is now approved, it takes now not more than 2 weeks to install the charger.
@Telegogo - so you just asked your landlord and they said sure? How do you meter or pay for power? If 10 more Teslas show up at your complex, would the landlord also be okay with installing more stations?
