Jon,
I rather imagine it'll be like the E2 nightclub in Chicago or that fire in NJ ?
When someone get hurt because of the poor installation ( code violation's ) then everyone whoever worked in/on the building will be investigated.
Some-one is going to pay the piper.
Seems as though many installers, inspectors, owners, gamble that it won't happen to them.
Another problem is, an inspector just cannot look at everything, for instance, the inspector would have to be on both ends of a cable pull, and that would be on every electrical installation that day!
The installer, beit the electrical or the general contractor, must be responsible for their site.
Been on some multiple occupancies buildings lately and on every building the GC starts covering 300.21. Tomorrow I'll be inspecting a section of wall for 300.21, after the drywall is removed, hopefully today.
This is the 10th building of 12 such buildings, at least 70 " Party" fire walls so far.
The way I look at such practices, There should be at least 6 different persons involved for these installations. The Electrical contractor, the Electrical inspector, the General Contractor, the Building inspector, the Insulator and the Drywaller.
Each one should know when Fire Wall penetrations are violations.
