Romex in an abandoned chimney

Is it code to run romex from a basement to a second or third floor inside of an unused chimney?

Wouldn't be able to support it inside the chimney.

The chimney is dry and does not take in rain/snow etc.

I am not sure about code compliance (never seen this come up before), but it doesn't sound like a very good idea to me. From the code perspective, I believe this would be a damp location prohibiting the use of NM-B, UF cable would probably be required if it would be allowed at all. I am interested in what others have to say about the code on this one.

Thanks. More a question out of curiosity than anything. Other than it being a chimney, seems like a great way to get from A to B.

It may be mickey mouse, but that doesn't mean it's prohibited. Can you provide a code citation?

Off the cuff, I'd say it would be a fished cable and not subject to fastening requirements. If I were doing this, I'd use UF with a PVC sleeve and sheaves or bushings to avoid abrasion, or use flexible PVC. You might also be able to use ENT. Just throwing ideas out there; no idea if they're compliant or not.

A chimmney would make a nice chase. Perhaps running a 2'' or so pvc conduit with bell ends at the top and bottom. Make sure you cement off the top where it leaves the roof to keep those darned squirrels out.
