San Francisco investigates Elon Musk and Twitter over building violations and strange bathroom construction.

San Francisco officials are investigating Twitter after six former employees allege that owner Elon Musk’s leadership team broke laws in turning the company’s headquarters into a “Twitter Hotel” for workers being pushed to stay up late to transform the social media platform. The ex-employees also allege that Musk’s team ordered numerous changes to the company’s headquarters in a 1930s Art Deco building in downtown San Francisco that violated building codes. This is the latest investigation into Twitter, which Elon Musk took over late last year.
