Hi Dave. I don't understand what you mean. The only issue is the panel cover was removed during a small cosmetic remodel with the addition of a some can lights and 2 breakers to accomplish the addition of the can lights. Unfortunately, the panel box is behind a framed wooden door behind a laundry room door. I have since removed the wood frame and wood door as I am sure that is not code. However, because of the door and behind the laundry room door, we did not see it until after the contractors were gone. So, this has been a situation of chasing the contractors around and trying to fins the panel. Of course, no one admits to it.
ActionDaves point was that a simple cover missing should not necessitate replacing the entire panel. The deal with panels is that the cover and cabinet are listed assemblies iirc. Be interesting to find out from this inspector about what he does if an exception has to be made- A replacement cover DOES NOT automatically void any listing if made to the appropriate specs per UL for that panel.
OTOH, if you really want a cover, you/your landlord may end up just having to get the panel replaced- on the flip side, at least you will have a new panel/new breakers.
