An electrical contractor mounted a 12"x18" pullbox for a panel feeder close to a wall. The carpenter hung a layin ceiling just below the pullbox. The 18" dimension is split in two by a ceiling main T. Four inches are on one side of the T and 14" on the other side of the T. Is this box in violation of 314.29 that states it "can be rendered accessible without removing any part of the building"? The main T could be removed for access to the box but it would take time and be a little expensive. Is the layin ceiling "part of the building"? Thanks for your help!
