SF will allow (Currently, I get a different answer, and ask every time.) 40'!
However, I have seen simular existing/original installs that were whole house, and close to 80'. Like the one you mentioned.
The reactions you get here on this and other forums, is that it would never fly anywhere, anytime. I find it facinating. I have never seen SEC used here, except for oven feeds and sub-panels. Smurf tube is non existant, except for Oakland in slab, and no one stocks it.
And back to thread in this pic', Romex is subject to physical damage under 8' unless behind finish. And would not pass my personal standard 110.12 the way it run.
