David and Russell--thanks for your input! Here is the information from the electrical inspection:
Service The service was recently replaced with a new 3-meter pack.There was no sign of permitting, and the old undersized SE cable was not replaced, and there was not proper grounding and bonding.It is not clear if the 3-meter pack is PSEG approved.The ZINSCO sub-fed panel is now considered a safety hazard and needs to be replaced.There is not room for the new conduit to rise up the exterior wall to the point of attachment.The steps and newly laid cement must be torn up and replaced for the service to be replaced.There were several instances of unsafe electrical installations in the basement including a live wire that was laying at the foundation wall.
Price Easily $5000, could go to $6500 not including cement and step repair
2nd Floor Apt. The sub-fed panel has been placed in the stairwell which is in direct violation of the code.The neutral and ground wires are attached to the same buss which is a safety hazard, and needs to be remedied.Nearly all of the lighting and receptacle circuits show evidence of rewiring but the ground wires do not show conductivity to ground.This is evidence of poor electrical installation and possibly using old knob-and-tube wiring to feed these circuits which were found in the basement.Also, there are broken boxes and unsafe wiring practices evident throughout the inspection which led one to believe that the work was performed by an unqualified individual.The cheated wires must be found or the entire ungrounded circuits may need to be rewired.
Pricing to move the sub-fed panel, properly install bonding and grounding, and correct the ungrounded circuits $3500-$6000
Rear apt No entry was gained.The Electrical portion of the Home Inspection report shows ungrounded receptacles and possibly more.Considering the evidence in the rest of the building, it is possible that the circuits are also poorly installed by amateurs. The range to correctly install these circuits is $750-$2000
These prices do not include the patching of plaster or the repair of any other damaged surfaces.
