The suit says Killian told Davis that he would start getting the permits for Musk's restroom, but the suit paraphrases him responding: "We don't do that; we don't have to follow those rules."
According to the suit, he instead suggested Killian hire an unlicensed plumber to build the toilet since others wouldn't want to jeopardize their license by working on a project without a permit.
I suspect it's been going on for years and is why he had them illegally install a bathroom next to where he slept, so he wouldn't keep waking security going to pee so frequently
