During the renovation of a bathroom, these photos were taken of the violations as they were discovered:
This box was discovered behind one layer of tile and two layers of sheet-rock.
This switch box was set back at least 1.25 inches from the finished surface of the wall. Even with the "mounting-screw extension" only the very tip of the switch lever protruded beyond the cover plate
Another buried box, this time unsecured and with no cover. This one found behind the ceiling in the shower stall.
The receptacle was originally installed sometime in the '70's so it may predate the GFCI requirement. However, it was replaced within the last couple years and still no GFCI (the copper pipe is the vent stack for the sink that was mounted right next to it). The NM cable below was feeding a pull-chain light above the sink, no junction box, the splice simply buried in the wall.
This beauty was also buried in the ceiling. The original splices came through a crows-foot and were held behind that hanging light canopy before the NM was tied in. The NM cables feed the receptacle in the previous picture and an overhead light.
This is my favorite, it makes absolutely no sense: This is the setup for the vapor-tight light fixture in the shower stall. The feeder into the far octagon box, then into a custom J-box in the middle, both of which were buried behind the ceiling. There isn't even a splice inside the custom J-box: The conductors from the BX go right out of an open KO and join the fixture wires in that flying splice above the joist. If the BX had been simply connected directly to the box for the vapor-tight fixture, they would've saved two additional J-boxes and prevented several code violations.
