There is no one with any assets worth going after involved, is my take.
Apparently, there was an absentee landlord, an elderly Vietnamese man, whose daughter dropped by once a month to collect the rent. The residents were instructed to tell her that they only worked, not lived there.
Hope he's got a good lawyer.
If there is ANY paperwork in Oakland’s FD suggesting there might be violations, they will be on the hook.
(See how I found deep pockets without even being a lawyer?)
They will go after the city and the absentee landlord. The city will pay out as it appears they were aware of it and did nothing about it since they liked having the hippies around. Reports are had complaints about fire hazard specifically and visited more than once.
