Re: Electric Meter/Deck covers majority of it
Unfortunately, viewable isn't the criteria being used by WE energies on this one. According to the "general requirements" section of We energies handbook, all service equipment (meter sockets, troughs, tap boxes, transsockets , etc.) are to be installed per NEC 110.26. WE Energies further requires a meter height between 36" and 60" (from ground level to center line of meter.)
I've run into these problems before (generally the result of a deck installed with no permit pulled.) It can be a tough fix. Removing the decking, or providing a means by which it can be readily moved (hinged section) will get you your required three feet of clearance. But, unless you provide a means of egress from the deck to the ground in that area, you still won't be within the meter height requirements. All things considered, moving the metering equipment is usually the easiest course of action.
As to who is responsible? That would probably be best discussed with an attornet specalizing in real estate. A building inspector could hav caught it on the deck install, but that assumes a permit was pulled (highly unlikely.) A home inspector could have caught it pre-sale, but most HI's I've dealt with know only what is on their standardized checklist and I'm betting electric / gas and water metering isn't. Perhaps the previous owner can be held responsible, but I'm no lawyer so i won't comment on that.
