Paul on residential meters I believe bypass is required on the landlord meter in multifamily applications. Your best bet is to contact the power company for the town you are working in BEFORE you do any service instalations. Some also require a fifth terminal in their meter socket. Some also require you to make a permanent connection at the service drop on service upgrades as your connection will not be redone by them. On underground services most cases are the property owner owns the service lateral back to the transformer, or back to and up the pole. As for the gec terminating in the meter can I have heard of inspectors not allowing this although as pointed out they have no basis fo this and it is perfectly acceptable and legal. I suspect they have the same questions as you but they have not bothered to find the answer.
