EV:
As the 'local insp' there's not much I can do. Once a CO is issued for a premise, it's out of our hands.
The 'neon' signage is inside a window, and it appears that since the HV wiring was field extended, a permit would have been required. A 'plug-in' sign does not require a permit.
Signage like this 'appears'; it's tough to catch the installer.
I gave the pics to the Fire Dept (Fire Prevention) as they do inspections for what some may refer to as prop. maintenance.
Still trying to track down the installer.
