Growler nailed it on the head.
the inspector can usually keep your permit from being finaled if he finds problems elsewhere (depending on your jurisdiction) which makes it harder for the homeowner to ignore the needed upgrades or have a handiman perform the repairs
btw, trying to warrant your work when you extend from existing wiring, especially non-corforming wiring or panel boards really opens up a can of worms for you when it comes to trying to determine liability for repair costs in the future. you may know it wasnt your work causind additional problems but explaining that to homeowner is a much trickier proposition unless you can show clear demarcatioons between your new work and existing.
I preach to my guys all the time about segregating our new work from existing. i consider it nearly essential and will only allow extensions from existing in rare circumstances.
probably would not have even turned the first screw
or try to decide if I can segregate my work from the existing
or just figure that it's better for me to move on to something less risky
Get a permit and see if this city is OK with it.
