Oakland Fire that killed 36 people was a club for wild sex parties
"They had blocked my area off and the music was so loud you couldn't really hear stuff but they were rocking my trailer. I had to go out and tell them to get off my trailer, they were having sex up there."
Mack said the organizers of the sex party didn't clean up properly and used condoms were found littered on the floor.
She said: "All the carpets and furniture you see in the photos have either been p***ed on by cats or were used in the orgy."
Inside was a picture of squalid chaos. The filthy floors offer little space to move and corridors are like narrow rat runs. Nails protrude from rickety stairs and brick-work crumbles in the walls.
The footage, shot by former tenant Shelley Mack, shows her stepping over junk and trash as she tries to negotiate the hall ways before reaching a set of stairs made out of what looks like reclaimed wood.
It's believed several people lived inside the Ghost Ship including some in an indoor 'RV park'.
Visitors have described a squalid scene where cat faeces and used condoms are found on the floor and junk and 'art' is piled high in every room.
