Just bought a house built in 1902. I want to add a new light fixture in the dining room that requires running 12/2 cable to it since there is no existing fixture.
From putting an endoscope in the ceiling it looks like a drop ceiling was added at some point (I think?). It also looks like there is a gap between the 2x4s and the original ceiling.
Obviously, it would be easiest to run the wire for my light fixture in the gap rather than drill holes through the 2x4s.
So, my question is - can I run the wire in this gap or do I need to drill holes through the 2x4s? Will I be violating any codes by running the wire through the gaps of the drop ceiling?
